CONTEXT: Different imaging methods can identify the integrity of breast implants and also the extent of possible silicone leakage. Mammography, ultrasonography and magnetic resonance imaging are often used to evaluate the integrity of breast implants, usually in patients that are symptomatic for rupture. A group of clinically asymptomatic patients was taken as a sample. These patients wanted to remove or change their breast implants for psychological or cosmetic reasons. OBJECTIVE: The purpose of this study was to compare the efficacy of mammography, sonography and magnetic resonance imaging in the detection of breast implant rupture in an asymptomatic population. TYPE OF STUDY: Prospective study. SETTING: Department of Diagnostic Imaging, Universidade de São Paulo, São Paulo, Brazil. METHODS: The participants were 44 asymptomatic patients who subsequently had implants surgically removed. Eighty-three implants were evaluated by both film-screen mammography and high-resolution sonography and 77 implants were evaluated by magnetic resonance imaging. The sensitivity and specificity of mammography, ultrasonography and magnetic resonance imaging were assessed using predetermined diagnostic criteria for implant rupture. All radiological signs were discussed and false positives and false negatives were retrospectively evaluated to identify the pitfalls in the investigations. RESULTS: The respective sensitivity and specificity of mammography were 20% and 89%; sonography, 30% and 81%; and magnetic resonance imaging, 64% and 77%. The differences between patients with breast implants for cosmetic and oncological reasons were discussed. CONCLUSIONS: Our experience suggests that magnetic resonance imaging seems to be the best imaging method on its own for the evaluation of rupturing among asymptomatic patients.

Spondylodiscitis represents 2%–4% of all bone infections cases. The correct diagnosis and appropriate treatment can prevent complications such as vertebral collapse and spinal cord compression, avoiding surgical procedures. The diagnosis is based on characteristic clinical and radiographic findings and confirmed by blood culture and biopsy of the disc or the vertebra. The present study was developed with Clementino Fraga Filho University Hospital patients with histopathologically and microbiologically confirmed diagnosis of spondylodiscitis, submitted to magnetic resonance imaging of the affected regions. In most cases, pyogenic spondylodiscitis affects the lumbar spine. The following findings are suggestive of the diagnosis: segmental involvement; ill-defined abscesses; early intervertebral disc involvement; homogeneous vertebral bodies and intervertebral discs involvement. Tuberculous spondylodiscitis affects preferentially the thoracic spine. Most suggestive signs include: presence of well-defined and thin-walled abscess; multisegmental, subligamentous involvement; heterogeneous involvement of vertebral bodies; and relative sparing of intervertebral discs. The present pictorial essay is aimed at showing the main magnetic resonance imaging findings of pyogenic and tuberculous discitis.

Magnetic Resonance Imaging Mri

Magnetic resonance imaging (MRI) is used as a clarifying technique after a high-resolution ultrasound examination during pregnancy. Combining ultrasound with MRI, additional diagnostic information is obtained or ultrasound diagnosis is frequently corrected. High spatial resolution provides accurate radiological imaging of internal organs and widens possibilities for detecting perinatal development disorders. The safety of MRI and the use of intravenous contrast agent gadolinium are discussed in this article. There is no currently available evidence that MRI is harmful to the fetus, although not enough research has been carried out to prove enduring safety. MRI should be performed when the benefit outweighs the potential side effects. The narrative review includes several clinical cases of fetal MRI performed in Vilnius University Hospital Santaros Clinics.

Contents: Magnetic resonance imaging (MRI) is one of the medical diagnostic imaging techniques that can provoke or exaggerate anxiety in certain patients. It may sometimes lead to the cancelation of the MRI.   The lavender essential oil has a long historical anxiolytic benefit. Aim: This study aimed to examine the effect of lavender essential oil inhalation with a massage on anxiety level for patients undergoing closed magnetic resonance imaging. Methods: A quasi-experimental research (study/control group) was used to achieve the aim of this study. The study conducted at Magnetic Resonance Imaging Unit in Main University Hospital, Alexandria, Egypt. A convenient sample of 100 patients divided into the study and control group (50 patients for each). Two tools were used in the present study. Those were structured interview questionnaire that elicited the patients' sociodemographic characteristics, and State-Trait Anxiety Inventory to identify the patients' anxiety levels. Results: There were no statistically significant differences between both groups concerning the anxiety level before the MRI procedure (χ2=2.041, P = 0.495). While there were statistically significant differences between both groups concerning anxiety level post-MRI procedure and after receiving of interventions (χ2 =35.135, P=0.000), there was a highly statistically significant difference between anxiety level before and after receiving intervention in study group patients (t= 77.059, P=0.000). Conclusion: Patients undergoing a closed magnetic resonance imaging who inhaled and massaged their hands with Lavender essential oil exhibited a reduced level of anxiety compared to the control group and compared to their preintervention level. The study recommended using the lavender essential oil, which is an inexpensive and noninvasive intervention in reducing MRI anxiety or other anxiety-producing procedures.

Background: The diagnostic certainty of medullar tuberculosis (TB) without Pott disease is difficult to establish in a tropical environment with the large group of infectious, parasitic, and systemic myelopathies, despite the increasing availability of magnetic resonance imaging (MRI) data and improvement of biological exploration platforms. Methods: We retrospectively analyzed the files of 186 patients hospitalized in the Department of Neurology and Neurosurgery of the University Hospital Center of Conakry, Guinea, between 2008 and 2016 for the management of non-compressive and compressive myelopathy. Biological evidence of TB infection was demonstrated for 13 (6.9%) patients.  Results: Infectious clinical picture prior to the development of neurological signs was reported in 11 patients (84.6%). The neurological signs were summed up by the existence of a sensitivo-motor semiology of progressive evolution (100% of cases) with sphincter disorders in 11 patients (84.6%) and a medullary compression symptomatology with a lesion and under lesion syndrome from the outset in 4 patients (30.8%). Medullary MRI revealed an extensive intramedullary hypersignal in 9 patients with non-compressive myelopathy and in 4 cases, the lesions appeared in T1 hypersignal and T2 isosignal were localized. Lumbar puncture (LP) revealed lymphocytic pleocytosis, hypoglucorrhage (0.3 to 0.5 g/l), and leukocytosis. Conclusion: This study reveals a classic clinical, biological, neuroradiological, and evolutionary profile of compressive and non-compressive myelopathies. These results are important for the  therapeutic and evolutionary discussion of TB myelopathies for good management.

First Year Of Life

Central nervous system (CNS) abnormalities cause about 40% of infant deaths in the first year of life. In case of the detection of abnormalities by ultrasound, a pregnant woman should be offered prenatal magnetic resonance imaging (pMRI). The aims of our study were: (1) to evaluate the effectiveness of pMRI in the diagnosis of selected fetal CNS defects; and (2) to assess the possibility of replacing postnatal tests with prenatal magnetic resonance. The prospective and observational study was conducted between 2014 and 2017 at the University Hospital in Krakow. Patients with suspected CNS defects of the fetus were qualified for pMRI in the third trimester of pregnancy. Sixty patients were included in the study group. Prenatal MRI was characterized by low accuracy in the diagnosis of complex brain defects. Cohen’s kappa coefficient κ = 0.21 (95% CI 0.00–0.46). No evidence was found suggesting the replacement of postnatal tests with pMRI. MRI was characterized by low consistency of diagnoses in the case of complex brain defects. The possibility of replacing postnatal studies with pMRI was not supported.

Aims: The current work aimed to assess the diagnostically value of Magnetic Resonance Imaging (MRI) Double Inversion Recovery (DIR) sequence in diagnosing of multiple sclerosis. Methodology: This study conducted on (42 patients) from the Diagnostic Radiology and Medical Imaging Dep. at Tanta University Hospital in the period from March 2018 to December 2019. Results: In accordance to the total lesions loads, it was found that DIR was higher significantly than T2WI (P-value= 0.003 with a relative gaining of 22%), we found that double inversion recovery (DIR) sequence was higher significantly to FLAIR regarding the number of diagnosed lesions in 3 anatomical areas (Mixed W-GM, cortical and infra-tentorial) with relative gaining of 28%, 85% and 63% respectively. A non-significant change was found among the two sequences regarding peri-ventricular white matter, deep white matter and juxta-cortical lesions detecting. Conclusion: Conventionally MRI has corner-stone roles in diagnosing, characterizing and following-up of multi-sclerosis. Finally, we concluded that DIR can be used as a addition to or even as an alternative for typical T2 and FLAIR. Therefore, we strongly recommend the addition of DIR sequences in the everyday MR protocol of MS cases.
