Extensive use of magnetic resonance imaging (MRI) in clinical practice revolutionized our understanding of the pathogenesis of axis spondyloarthritis (aSpA) and treatment approaches. The use of MRI to diagnose non-radiographic aSpA is well established. At the same time, the possibility of its use for follow-up and treatment assessment is actively discussed.Objective: To present comparative analysis of clinical and laboratory data, reflecting the activity of the disease, and analysis of MRI results in patients with ankylosing spondylitis (AS) receiving biological disease modifying anti-rheumatic drugs therapy (bDMARDs).Patients and methods. The study included 39 patients with AS, mainly men (74.3%), 24 patients (61.5%) had late and 15 (38.5%) – advanced stage of the disease. The average age was 41.0 [34.0; 48.0] years. All patients were administered bDNARDs; inhibitors of the tumor necrosis factor α or inhibitors of interleukin 17 were drug of choice. The median of treatment duration was 1.5 [1.0; 4,5] year. All patients had sacroiliac (SI) and spinal MRI. The activity of the disease was estimated using BASDAI and ASDAS-CRP/ESR indexes, functional disorders – using the BASFI questionnaire. Results and discussion. There was no significant difference in disease activity between patients with osteitis in the SI/spine or without it: BASDAI – 4.7 [2.7; 5,5] and 4.2 [2.9; 8,1], respectively (p=0.533); ASDAS-ESR – 2.6 [2.2; 3,0] and 2.6 [2.2; 3,2], respectively (p=0.725); ASDAS-CRP – 2.5 [2.1; 3,4] and 3.1 [2.8; 3.9], respectively (p=0.172). There was no significant difference in the number of osteitis foci between group of patients who have achieved the therapeutic target (ASDAS < 2.1) and those who have not (ASDAS ≥2.1) – 1.0 [0.0; 3.5] and 1.0 [1.0; 4.0], respectively, (p=0.376), and no difference in amount of inflammatory changes – 1.0 [0.2; 1.7] and 0.1 [0.0; 1,1] cm3, respectively (p=0.124). Conclusion. The data suggests a limited MRI informative value as a method for managing the efficacy of bDMARDs treatment in patients with the advanced / late stage of the AS.

Glomus tumor is one of the most common temporal bone tumors. Most of them are benign and locally invasive, some are occasionally able to metastasize and have signs of malignancy. Diagnostic imaging is necessary before treatment. Computer tomography (CT) is traditionally used as a primary method of diagnosis, to recognize changes in the temporal bone. Role of magnetic resonance imaging (MRI) in temporal bone tumor diagnosis is not definitively determined.Purpose. To assess the possibilities of computer and magnetic resonance tomography, to develop an algorithm for the application of diagnostic imaging methods in the diagnosis of glomus tumors of the temporal bone.Material and methods. The article presents the experience of diagnosing 30 patients with glomus tumors.Results. The tympanic form of the glomus tumor was observed in 11 cases (37%), tympano-yugular in 19 cases (63%). CT and MRI data totally coincided in cases of small tumors (type A and B). In the presence of extended forms CT ability of assessing bone invasion, involvement of the internal carotid artery, internal jugular vein, and dural sinuses was lower than the MRI.

The Impact

Background:Bath Ankylosing Spondylitis Metrology Index (BASMI) is an instrument developed to assess spinal and hip mobility. The relationship between BASMI and disease activity is not always linear and, above all, the data that correlate the variation in BASMI values (ΔBASMI) with the variation in disease activity scores and response to treatment are not unanimous.Objectives:Explore the effect of biological disease-modifying antirheumatic drugs (bDMARD) in spine mobility (as assessed by BASMI) and the associations between ΔBASMI and disease activity.Methods:Observational retrospective study was performed including consecutive patients with the diagnosis of Spondyloarthritis (SpA) followed at our Rheumatology Department. Demographic, clinical, including Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), BASMI, Ankylosing Spondylitis Disease Activity Score with erythrocyte sedimentation rate and C-reactive protein (ASDAS ESR and ASDAS CRP, respectively), and laboratorial data were collected from our national database at baseline, 6 and 12 months after initiation of a bDMARD. The variation of each parameter was calculated as the difference between the levels recorded at 6 and 12 months and the reference level and presented in the form of Δ. Statistical analysis was performed using SPSS 23.0. Correlations between variables were studied using Spearman correlation analysis and comparison between groups was performed using Wilcoxon and Kruskal-Wallis tests.Results:Median age of patients (n=178) was 42 years old [34, 50], 92 (51.7%) were males with a median disease duration of 4.9 [1.0, 10.3] years. One hundred and twenty-six patients (70.8%) had Ankylosing Spondylitis, 15 (8.4%) Inflammatory Bowel Disease related SPA and 30 (16.9%) Undifferentiated SpA. Fifty four (30.3%) patients were taking glucocorticoids and regarding conventional synthetic disease-modifying anti-rheumatic drugs use before starting the bDMARD: Sulfasalazine (52, 29.2%), Methotrexate (31, 17.4%) and Leflunomide (3, 1.7%). Regarding the bDMARD, only one patient started Secukinumab and the others a Tumor necrosis factor inhibitor (TNFi) [Golimumab (n= 64, 36.0%), Adalimumab (n=36, 20.2%), Infliximab (n= 35, 19.7%), Etanercept (n= 32, 18.0%) and Certolizumab (n= 10, 5.6%)].The majority of the patients had very high disease activity at baseline (86.0%, n=153); median ESR was 29 mm/h [15, 47], median CRP was 13.7 mg/L, [6.60, 27.3], median ASDAS CRP was 7.6 [6.0, 9.0] and median BASMI was 8.0 [7-0, 9.0]. After 6 and 12 months of treatment, mean ESR, CRP, ASDAS-CRP and BASMI were significantly lower than mean baseline values (p<0.01), with median ASDAS-CRP at 12 months of 2.20 [1.50, 2.90] and median ΔBASMI of -4.10 [-5.50, -2.40].BASMI at baseline showed a moderate correlation with ASDAS CRP (r=0.468, p<0.01), BASDAI (r=0.496, p<0.01) and patient visual analogic scale (VAS) (r=0.563, p<0.01). No correlations were found between BASMI and CRP, ESR, physician VAS or the consumption of nonsteroidal anti inflammatory drugs at baseline.A significant positive correlation was found between ΔBASMI and ΔASDAS at 6 months and 12 months (r=0.243, p=0.02; r=0.286; p<0.01) and also between ΔBASMI and ΔBASDAI at 6 and 12 months (r=0.183, p=0.04; r=0.291, p=0.02). No correlations were found between ΔBASMI and ΔCRP or ΔESR. No differences were observed in ΔBASMI, regarding the bDMARD of choice.Conclusion:In our cohort, starting a bDMARD improved BASMI scores through a 12 month period and there was a correlation between the variation of BASMI and disease activity improvement. As such, a TNFi may retard the progression of spinal mobility dysfunction in SpA patients. We cannot draw conclusions regarding differences between TNFi and interleukin 17 inhibitors and further work is needed to clarify possible differences in their impact in improving spine mobility.Disclosure of Interests:Salomé Garcia: None declared, Bruno Miguel Fernandes: None declared, Sara Ganhão: None declared, Maria Rato: None declared, Filipe Pinheiro: None declared, Georgina Terroso: None declared, Miguel Bernardes Speakers bureau: Abbvie, Amgen, Biogen, Eli-Lilly, Glaxo-Smith-Kline, Pfizer, Janssen, Novartis, Lúcia Costa: None declared

Background: Borrelia infections, especially chronic neuroborreliosis (NB), may cause considerable diagnostic problems. This diagnosis is based on symptoms and findings in the cerebrospinal fluid but is not always conclusive. Purpose: To evaluate brain magnetic resonance imaging (MRI) in chronic NB, to compare the findings with healthy controls, and to correlate MRI findings with disease duration. Material and Methods: Sixteen well-characterized patients with chronic NB and 16 matched controls were examined in a 1.5T scanner with a standard head coil. T1- (with and without gadolinium), T2-, and diffusion-weighted imaging plus fluid-attenuated inversion recovery (FLAIR) imaging were used. Results: White matter lesions and lesions in the basal ganglia were seen in 12 patients and 10 controls (no significant difference). Subependymal lesions were detected in patients down to the age of 25 and in the controls down to the age of 43. The number of lesions was correlated to age both in patients (ρ = 0.83, P<0.01) and in controls (ρ = 0.61, P<0.05), but not to the duration of disease. Most lesions were detected with FLAIR, but many also with T2-weighted imaging. Conclusion: A number of MRI findings were detected in patients with chronic NB, although the findings were unspecific when compared with matched controls and did not correlate with disease duration. However, subependymal lesions may constitute a potential finding in chronic NB.

Background Creutzfeld-Jacob disease (CJD) is a rare, progressive disease that has a vast clinical manifestation range. Cranial magnetic resonance imaging (MRI), electroencephalography (EEG), and measurement of 14-3-3 in cerebrospinal fluid (CSF) may offer a pragmatic approach in the diagnosis of CJD as an alternative to histopathological confirmation. Purpose To present the symptoms and signs of the CJD patients in regard to radiological and neurophysiological findings. Material and Methods We collected all cases with the diagnosis of probable CJD admitted to our neurology department between June 2010 and June 2014. The medical records and laboratory data, clinical features, results of MRI (including diffusion weighted images), EEG and CSF evaluations, and other laboratory data to exclude other possible diagnoses were recorded. None of the patients underwent biopsy or autopsy for histological diagnosis. Results Of 20 patients, 11 (55%) were men and nine (45%) were women. The mean age at disease onset was 60.0 ± 9.5 years (age range, 47–80 years). All patients without exception had characteristic abnormalities in DWI and/or FLAIR on admission, about 4 months after the initial symptom. Periodic complexes on EEGs characteristic for CJD were detected only in 10 patients (50%) on admission and in 13 patients (65%) during disease course. Out of 14 patients who underwent CSF examination, 11 (78.5%) were positive for 14-3-3 protein. Conclusion Although the definite diagnosis of CJD is made histopathologically, we aimed to discuss the value of magnetic resonance imaging in the diagnosis of CJD in respect to EEG findings and protein 14-3-3 levels in CSF.

Investigation which devoted to the study of the age characteristics of the human body are becoming increasingly important. Magnetic resonance tomography is the most informative diagnostic method for intravital visualization of tissues and structures of the brain. It also allows you to more accurately see the picture of morphological features with age-associated changes. The aim of the study was to carry out a comparative analysis of the age-related morphometric characteristics of the cerebellum in male with mesocranic type of cranium in young and old age according to the data of magnetic resonance tomography. The analysis of the results of a morphometric study of the cerebellum on tomograms of 91 men examined for medical reasons was carried out. Depending on the age, the subjects were divided into two groups. Group I included 52 young men (22–27 years old, inclusive), group II included 39 elderly men (from 78 to 83 years old, inclusive). The transverse, longitudinal and vertical dimensions of the cerebellum were determined. When comparing the parameters of the linear dimensions of the cerebellum in the studied age groups of men, a statistically significant decrease in all indicators in old age compared with young age was revealed (p=0.042). There was no statistically significant difference between the parameters of the longitudinal and vertical sizes of the cerebellar hemispheres in individuals of each age group (p>0.05); there is a tendency for these sizes to prevail in the right cerebellar hemisphere. The results obtained can serve as the equivalent of the age-related anatomical norm of the cerebellum in young and old men, which will make it possible to use these data in basic and clinical research, as well as in medical practice.

Objective The objective of this study was to determine whether white matter hyperintensities (WMHs) in subjects with migraine are related to alterations in resting cerebral blood flow (CBF). Methods Migraine with aura (MWA), migraine without aura (MwoA), and control subjects were enrolled in a 1:1:1 ratio. WMH load was scored based on fluid-attenuated inversion recovery/T2-weighted magnetic resonance imaging (MRI) using a previously established semi-quantitative scale. Global and regional CBFs were quantified using arterial spin labelled perfusion MRI. Integrity of the circle of Willis was assessed with magnetic resonance angiography (MRA). Results A total of 170 subjects were enrolled (54 controls, 56 MWA, and 60 MwoA). There was no significant difference in subjects with ≥1 WMH across groups (22% controls, 29% MWA, 35% MwoA; p = NS). Similarly, high WMH load was not significantly different across groups (16.7% controls, 21.4% MWA, 25.0% MwoA; p = NS). High WMH load was strongly associated with increasing age (odds ratio: 1.08 per year, 95% confidence interval: 1.02–1.13, p = 0.01). Resting CBF was similar across groups, but was significantly higher in women. In MWA subjects with high WMH load, CBF was substantially lower ( p = 0.03). No association between WMH load and CBF was seen in control or MwoA subjects. Conclusions WHMs in MWA may be related to alterations in resting CBF.

Objective. The aim of this study is to evaluate the magnetic resonance imaging (MRI) findings of central neural system (CNS) superficial siderosis cases and the diagnostic contribution of the susceptibility-weighted imaging (SWI) sequence to conventional imaging. Method. TSE T2-weighted and SWI-MRI of 26 patients diagnosed as CNS-superficial siderosis (CNS-SS) were retrospectively evaluated with 3-Tesla MRI. The localization and type of involvement of SS were reviewed. Results. The CNS-SS were divided into two categories as central amyloid angiopathy-SS (CAA-SS) and non central amyloid angiopathy-SS (non-CAA-SS). In non-CAA cases, the involvement was typical (classic) in 5 cases and atypical in 9 cases. In 12 of these cases (85.7%), SS findings were observed on both turbo spine echo (TSE) T2 images and SWI imaging, while in 2 cases (14.3%) SS was detected only on SWI images. In 7 of the CAA-SS cases, involvement was focal type SS (58.33%), while 5 cases had diffuse type SS (41.67%) involvement. In the vast majority of cases (n = 10) of this type of SS, involvement was detected only in SWI images, while siderosis was not detected in TSE T2 images. In addition, occult cerebral vascular malformation accompanying SS, which can be observed only in the SWI sequence, was found in a total of 4 cases. In the cross-matching statistical analysis performed between CAA-SS and non-CAA-SS groups and subgroups, SWI was found to be significantly superior to T2 in detecting SS in the CAA-SS group (p:0,007). Conclusions. SWI imaging was superior in detecting SS and detecting cerebral occult vascular malformation in CAA-SS cases. Although the detectability of SS by SWI was high in other groups, no statistically significant difference was found. Under these circumstances, we think that it will be beneficial to add SWI imaging to the routine imaging protocol in cases with suspected CNS-SS.

Objective We compared the diagnostic values of mammography and magnetic resonance imaging (MRI) for evaluating breast masses. Methods We retrospectively analyzed mammography, MRI, and histopathological data for 377 patients with breast masses on mammography, including 73 benign and 304 malignant masses. Results The sensitivities and negative predictive values (NPVs) were significantly higher for MRI compared with mammography for detecting breast cancer (98.4% vs. 89.8% and 87.8% vs. 46.6%, respectively). The specificity and positive predictive values (PPV) were similar for both techniques. Compared with mammography alone, mammography plus MRI improved the specificity (67.1% vs. 37.0%) and PPV (91.8% vs. 85.6%), but there was no significant difference in sensitivity or NPV. Compared with MRI alone, the combination significantly improved the specificity (67.1% vs. 49.3%), but the sensitivity (88.5% vs. 98.4%) and NPV (58.3% vs. 87.8%) were reduced, and the PPV was similar in both groups. There was no significant difference between mammography and MRI in terms of sensitivity or specificity among 81 patients with breast masses with calcification. Conclusion Breast MRI improved the sensitivity and NPV for breast cancer detection. Combining MRI and mammography improved the specificity and PPV, but MRI offered no advantage in patients with breast masses with calcification.
