ABSTRACT Introduction : This study seeks to characterize lesion distribution in Parsonage–Turner Syndrome (PTS) using high‐resolution MRI. Methods MRIs of 27 patients with clinically confirmed PTS were reviewed. Two radiologists independently evaluated the brachial plexus proper, side and terminal branches, more distal, upper extremity nerves. Results All had at least 1 involved nerve. MRI revealed that appeared normal 24 patients; 3 other patients, signal hyperintensity was seen immediately...
Vaccination is one of the several known triggers Parsonage-Turner syndrome (PTS). This case series describes two individuals with clinical presentations PTS whose symptoms began 13 hours and 18 days following receipt Pfizer-BioNTech BNT162b2 Moderna mRNA-1273 COVID-19 vaccine, respectively. The diagnosis was confirmed by using both electrodiagnostic testing 3.0-T MR neurography. Although research needed to understand association between vaccination, neurography may be used help confirm...
The role of MRI in identifying hourglass constrictions (HGCs) nerves Parsonage-Turner syndrome (PTS) is largely unknown.Six patients with PTS and absent or minimal recovery underwent MRI. Surgical exploration was performed at identified pathologic sites.The time between symptom onset surgery 12.4 ± 6.9 months; the 1.3 0.6 months. Involved included suprascapular, axillary, radial, median nerve anterior interosseous pronator teres fascicles. Twenty-three constriction sites 10 were on A...
We followed 35 consecutive patients with scaphoid nonunions in a prospective longitudinal registry. All were treated curettage, non-vascularized autogenous grafting and headless screw fixation. Preoperative magnetic resonance imaging, intraoperative bleeding points histopathological analysis of cancellous bone the proximal pole recorded as measures viability. Healing was categorized ≥50% bony bridging on computed tomographic images plane scaphoid. Nine 23 poles demonstrated ischaemia imaging...
Study Design. A cohort study. Objective. The aim of this study was to evaluate the clinical utility Zero-Echo-Time (ZTE) magnetic resonance imaging (MRI) for assessment cervical neural foraminal stenosis (CNFS) through comparison inter-modality [computed tomography (CT) and ZTE-MRI] CNFS grade severity agreements. Summary Background Data. Conventional MRI limited in its ability provide direct visualization cortical bone. highly organized tissue structure bone results very short T2 values...
Purpose To determine the diagnostic accuracy of magnetic resonance (MR) imaging for differentiating synovial patterns in patients with total knee arthroplasty (TKA), whether differs index versus revision TKA, and interobserver intraobserver reliability assessment at MR imaging. Materials Methods This retrospective cross-sectional study included 108 consecutive TKAs who underwent within 1 year prior to surgery from 2012 2014. Institutional review board approval was obtained, waiver need...
Abstract Introduction/Aims Hourglass‐like constrictions (HGCs) occur in neuralgic amyotrophy (NA), but the earliest time at which they can be recognized by imaging is poorly understood. We aimed to determine prevalence of abnormal findings acute phase NA. Methods Magnetic resonance neurography (MRN) and high‐resolution ultrasound (US) examinations were performed five sites. The investigation included 39 patients with NA who underwent within 31 days symptom onset. Correlation between...
<h3>ABSTRACT</h3> <h3>BACKGROUND AND PURPOSE:</h3> To train and evaluate an open-source generative adversarial networks (GANs) to create synthetic lumbar spine MRI STIR volumes from T1 T2 sequences, providing a proof-of-concept that could allow for faster examinations. <h3>MATERIALS METHODS:</h3> 1817 examinations with sagittal T1, T2, sequences were accumulated randomly divided into training, validation, test sets. GANs trained using the as inputs, optimized validation set, then applied...
Abstract Introduction In this study we tested the hypothesis that fascicular constrictions (FCs) of median nerve proximal to elbow joint characterize anterior interosseous syndrome (AINS). Methods Magnetic resonance neurography (MRN) and ultrasound (US) examinations were evaluated in 45 patients with clinically suspected AINS. All 22 at site 1 underwent MRN 8 US; all 23 2 US. Results Median FCs identified cases; and/or enlargements 88% US cases. Most mediannerve posterior/posteromedial...
Abstract Introduction/Aims Hourglass‐like constrictions (HGCs) of involved nerves in neuralgic amyotrophy (NA) (Parsonage–Turner syndrome) have been increasingly recognized with magnetic resonance neurography (MRN). This study sought to determine the sensitivity HGCs, detected by MRN, among electromyography (EMG)‐confirmed NA cases. Methods retrospectively reviewed records patients clinical diagnosis NA, and EMG confirmation, who underwent 3‐Tesla MRN within 90 days at a single tertiary...
