Full field of view coronal chest magnetic resonance imaging (MRI) routinely displays bilateral images of the brachial plexus, surface anatomy, and anatomic structures. Eighty patients had chest radiographs correlated with surgery for thoracic outlet syndrome. The PA chest film findings correlated with the surgical findings: smaller thoracic inlet on the concave side of the cervicothoracic spine...

PURPOSE To assess intra-observer, inter-observer and inter-modality (CT vs. MRI) reproducibility of liver surface nodularity (LSN) scores measured with software used for detection of liver fibrosis. METHODS This IRB-approved retrospective study included patients with both abdominal CT and MRI within 6 months of histopathologic sampling. Two independent observers used post-processing software ...

BACKGROUND AND PURPOSE A rapid and sensitive MR imaging technique would be beneficial for screening of metastatic nodes in the neck. We preliminarily evaluated the coronal MR imaging with a turbo short tau inversion recovery (STIR) sequence for that purpose. METHODS The coronal turbo STIR imaging (repetition time [TR]/echo time [TE]/inversion time [TI] = 3850 ms/20 or 80 ms/180 ms) and axial ...

PURPOSE To evaluate meniscofibular ligament (MFibL) at the posterolateral corner of the knee joint on the magnetic resonance arthrography (MRA) with 70° knee flexion. MATERIALS AND METHODS The MRA of the knee joint was performed at 70° knee flexion. Eighteen patients (19 knee joints) underwent scanning of sagittal, coronal, and axial fat-suppressed T1 weighted images (T1FS), and coronal fat-s...

There is a wide range of values reported in volumetric studies of the amygdala. The use of single plane thick magnetic resonance imaging (MRI) may prevent the correct visualization of anatomic landmarks and yield imprecise results. To assess whether there is a difference between volumetric analysis of the amygdala performed with single plane MRI 3-mm slices and with multiplanar analysis of MRI ...

INTRODUCTION: The use of diffusion-weighted imaging (DWI) for the evaluation of peripheral nerves was recently introduced by Takahara et al. [1]. Since the signal from the nerves at DWI originates from water within the nerve sheath, this method can be referred to as diffusion-weighted nerve sheath imaging (DW-NSI). There are two major limitations related to echo-planar imaging (EPI)-based DW-NS...

Between 5 and 30% of patients with Behçet's disease will present neurological signs during the course of their illness. In order to evaluate the radiological signs on neuro-behçet disease, we studied consecutive patients in whom the diagnosis of this disease was retained, and who referred from January 2004 to December 2011 to the neurology and internal medicine departments in Mohammed VI univer...

Thirty-seven patients with suspected pituitary tumors were evaluated prospectively with MR imaging at 1.5 T. MR detected a microadenoma at its correct location in all eight patients who underwent transsphenoidal surgery, while CT showed a focal abnormality in the correct location in only four of the eight patients. In patients who were clinically and endocrinologically considered to harbor a mi...

OBJECTIVE This study was carried out to evaluate the role of magnetic resonance imaging (MRI) in preoperative assessment of fistula-in-ano. SUBJECTS AND METHODS Twenty-six patients (21 male and 5 female, age 19-65 years) were prospectively studied from July 1999 to December 2001 using a 1.0-tesla superconducting magnet. T(1)-weighted fast spin echo (T1W FSE) images before and after gadolinium...

BACKGROUND AND PURPOSE The substantia innominata can be visualized on coronal thin-section T2-weighted MR images. The purpose of this study was to investigate the morphologic changes of the substantia innominata in normal aging by using MR imaging and to determine whether the changes in this structure on MR images were specific to Alzheimer disease (AD). METHODS The thickness of the substanti...
