High resolution T2 magnetic resonance imaging (MRI) can provide exquisite detail of internal auditory canal (IAC) and cerebellopontine angle (CPA) lesions. In this retrospective case series, blinded imaging sequences were delivered to three radiologists and compared with previously archived clinical reads that were non-blinded and incorporated both T1+C and T2 sequences together. This article demonstrates high sensitivity and specificity for high resolution T2 MRI particularly with lesions >5mm.

Objective: The purpose of this study was continuous quality improvement (CQI) of head and neck CT angiography (CTA) in the neuroradiology practice of a tertiary care medical center.
Materials And Methods: We conducted baseline quality audits of 50 consecutive head or neck CTAs, including referrals for a variety of indications from emergency department, ambulatory, and inpatient settings. Neuroradiologists as a group used Likert-type questionnaire items to assess scan quality.
Article Synopsis
- The study investigates how the attenuation (density) of renal tumors changes during different phases of a contrast-enhanced CT scan to differentiate them from kidney cysts.
- Researchers analyzed CT scans of 20 patients with 21 confirmed renal tumors, measuring attenuation values in both corticomedullary and nephrographic phases, and comparing them with simple cysts.
- Results indicated that most renal tumors showed a significant attenuation change of over 10 Hounsfield units (HU) between the two phases, suggesting that such changes are indicative of a renal neoplasm, while minimal changes are more consistent with high-density cysts.
