- The study investigates the effectiveness of a single contrast agent injection at a 1.5 T MRI system for enhancing both MR angiography (MRA) and MR neurography (MRN) in diagnosing brachial plexopathy.
- Using this approach, researchers found that contrast-enhanced 3D-T2-STIR images significantly reduced background noise from veins, lymph nodes, and muscles, thereby improving the visibility of the brachial plexus.
- The results also indicated a notable correlation between brachial plexopathy and vascular issues, with 39% of cases showing concurrent abnormalities in subclavian and axillary blood vessels.
BACKGROUND The aim of this study was to introduce a novel method combining contrast-enhanced magnetic resonance angiography (CE-MRA), short inversion time inversion recovery sampling perfection with application-optimized contrasts using different flip angle evolutions (T2-STIR-SPACE) and volumetric interpolated breath-hold examination (VIBE) sequences in the assessment of thoracic outlet syndrome (TOS). MATERIAL AND METHODS CE-MRA, T2-STIR-SPACE, and VIBE techniques were employed to evaluate neurovascular bundles in 27 patients clinically suspected of TOS. Images were evaluated to determine the cause of neurovascular bundle compression.

- The study aimed to assess how effective diffusion-weighted MRI (DWI) is at distinguishing between benign and malignant polypoid gallbladder lesions.
- A total of 23 lesions were examined, with results showing significant differences in signal intensity and average ADC values between benign and malignant lesions, indicating that malignant lesions generally have higher signal intensity and lower ADC values.
- The findings suggest that DWI could serve as a reliable diagnostic tool, as it demonstrated a sensitivity of 92%, specificity of 100%, and overall accuracy of 96% in identifying malignant cases.
