Comparison of T2  MSME and STIR methods in assessment of muscle emergency changes in patients with LGMD R2

Introduction. The identification of early edematous changes using MRI and the assessment of the nature of their distribution among the muscles is important for the diagnosis of dysferlinopathy and the differentiation of hereditary muscular dystrophies from inflammatory myopathies. Purpose of the study: to assess the capabilities of STIR and T2 MSME methods in the diagnosis of early edematous changes in the muscles of patients with LGMDR2. Materials and methods: We examined 20 patients with clinical manifestations of dysferlinopathy, with an average age of 35 (24; 44) years. Magnetic resonance imaging of the muscles of the pelvic girdle and lower extremities was performed by 20 patients and a control group equivalent in sex and age.Results. The T2 MSME (ms) method based on the calculation of relaxation time has the highest diagnostic accuracy in detecting early edematous changes in muscles. The sensitivity of the STIR method was 56%, and the specificity was 100%. Conclusion. Dysferlinopathy is characterized by diffuse edema of the least affected muscles. STIR is optimal for differential diagnosis of myopathies characterized by edematous changes. Whereas, for the assessment of minimal edematous changes, T2 MSME is the most acceptable.

Work Up

This article reports the case of a 68-year-old patient with anti-HU antibodies paraneoplastic encephalitis. The clinical manifestations were atypical and the paraclinical work-up, notably the magnetic resonance imaging (MRI) showing bilateral posterior thalamic hyperintensities (pulvinar sign), misleadingly pointed towards a variant Creutzfeld–Jakob disease. After presenting the case, the differential diagnosis of the pulvinar sign is discussed along with other important diagnostic considerations.

The Mean

Background The aim of this study is to investigate the role of diffusion-weighted imaging (DWI) in the differential diagnosis of sacroiliitis. Purpose To compare the sacroiliac magnetic resonance imaging (MRI) examinations of patients with suspected active sacroiliitis with patients with acute SpA MR findings and the DWI examinations of patients with acute brucella sacroiliitis, and thereby determine whether DWI can contribute to the differential diagnosis. Material and Methods A total of 84 patients were included in the study and were separated into three groups: group 1 (13 women, 6 men) comprised cases with brucella positive for sacroiliitis; group 2 (17 women, 19 men) comprised cases negative for brucella but with sacroiliitis; and group 3 (16 women, 13 men) comprised cases negative for brucella and sacroiliitis. Results The mean bone marrow apparent diffusion coefficient (ADC) values independently of edema were determined as 0.71 × 10−3 in sacroiliitis and brucella-positive patients, as 0.53 × 10−3 in brucella-negative and sacroiliitis-positive patients, and as 0.43 × 10−3 in the control group of brucella-negative sacroiliitis-negative patients. In the ADC measurements taken from areas of evident edema in patients with sacroiliitis, the mean values were 0.13 × 10−3 in the brucella-positive group and 0.12 × 10−3 in the brucella-negative group. Conclusion By adding DWI, which is a rapid MR sequence, to sacroiliac joint MR examination, normal bone marrow and bone marrow with sacroiliitis can be objectively differentiated with ADC measurements in addition to visual evaluation.

Hematological Tumors

The use of dynamic enhanced magnetic resonance imaging technology can effectively explore the diagnosis and clinical application of hematological malignancies. This paper selected 60 patients with hematological malignancies from 2015 to 2019; all of whom were diagnosed with hematological malignancies, including 40 men and 20 women, aged between 40 and 77 years. The main clinical manifestations of the patient are hematological malignancies, fever, and other symptoms. We used Siemens 3.0T to perform MRI and dynamic enhanced MRI examinations on 30 patients with hematological tumors. The PACS system was used to collect and organize clinical data. All patients were pathologically confirmed and clinically diagnosed with hematological malignancies. Based on the clinical data of the patients, retrospective analysis and summary were conducted and the clinical manifestations of hematological malignancies were discussed. The results showed that the diagnostic accuracy of 30 cases of dynamic enhanced MRI was 100%, while the diagnostic accuracy of ordinary MRI was lower than that of dynamic enhanced MRI, P < 0.05 , and the difference was statistically significant. In addition, compared with dynamic enhanced MRI and MRI, P > 0.05 , the difference was not statistically significant. Therefore, the application of dynamic enhanced MRI in the diagnosis of hematological malignancies is valuable.

The diagnosis of multiple sclerosis (MS) is quite challenging due to its variable clinical manifestations and lack of a definitive test. Magnetic resonance imaging (MRI) is one of the tools to confirm the diagnosis and also helps in differential diagnosis with other disorders and in exclusion of MS-mimicking diseases. In this article, based on the analysis of clinical cases, we discuss the differential diagnosis of MS with the following non-tumorous multifocal brain lesions: vascular abnormalities caused by hypoxia and ischemia, cerebral autosomal dominant angiopathy with subcortical infarctions and leukoencephalopathy, Susac syndrome, primary angiitis of the central nervous system, and neurosarcoidosis. We present both MRI criteria for MS and disorders that have similar MRI signs, and additional clinical and laboratory data that is essential for correct diagnosis.

Background: Hypermobile lateral meniscus is difficult to diagnose with imaging due to its absence of tears or anomalies. We aimed to clarify the accuracy of the preoperative diagnosis using magnetic resonance imaging (MRI). Methods: The preoperative MRI status of the posterosuperior popliteomeniscal fascicle (sPMF), anteroinferior popliteomeniscal fascicle (iPMF), and popliteal hiatus were examined retrospectively on sagittal images in the hypermobile lateral meniscus group (n = 22) and an age- and gender-matched control group (n = 44). These statuses were evaluated by a logistic regression analysis to assess their degree of diagnostic accuracy. Results: The area under the curve (AUC) of the sPMF, iPMF, popliteal hiatus, and all three criteria combined was 0.66, 0.74, 0.64, and 0.77, respectively (low, moderate, low, and moderate accuracy, respectively). The odds ratios of the most severe type 3 forms of the sPMF, iPMF, and popliteal hiatus for hypermobile lateral meniscus were significantly high (5.50, 12.20, and 5.00, respectively). Although the diagnostic accuracy was not high enough, the significantly higher odds ratio for type 3 may indicate a hypermobile lateral meniscus. Conclusion: a definitive diagnosis of hypermobile lateral meniscus is difficult with MRI findings alone; however, MRI evaluations of the iPMF, sPMF, and the widening of popliteal hiatus can be used as an adjunct to diagnosis.

The aim of the review was to summarize information on clinical manifestations, diagnostic features, as well as methods for correction of scar defects after cesarean section (CS) outside pregnancy. Lack of the scar after CS, niche, isthmocele are a myometrium defect in the area of scar after CS, which is most often detected by ultrasound, sonohysterography or magnetic resonance imaging and is manifested by postmenstrual bleeding from the genital tract. In some cases, it can cause menorrhagia, dyspareunia, pelvic pain, infertility, uterine rupture during subsequent pregnancy and childbirth. Conservative therapy or surgical treatment with laparoscopy, laparotomy or vaginal approach is carried out depending on the symptoms, size of the defect, the thickness of the residual myometrium, as well as the womans reproductive plans.
