Basilar occlusion outcomes did not differ between CT and MRI selection in a trial analysis

The edition in brief

In a post hoc analysis of the ATTENTION trial of acute basilar artery occlusion, 277 patients assessed with CT and 63 with MRI had similar odds of a 90-day modified Rankin score of 0 to 3 (OR 0.99, 95% CI 0.50–1.95), in both thrombectomy and medical arms. MRI did not significantly delay puncture. CT is sufficient as the first-line selection tool, which matters where MRI is not available around the clock. SCARLET-1 tested an AI prostate MRI system on 1,974 external patients in 12 countries: AUC was 0.84 to 0.89 and agreement with standard-of-care diagnosis met interchangeability criteria, though performance varied widely between sites and with image quality. The 2026 ACR Appropriateness Criteria for postmenopausal acute pelvic pain keep ultrasound first, with MRI or CT when ultrasound is inconclusive. QIBA guidance for liver MR elastography states a change in stiffness of at least 19% is needed to call it real. The pearl covers metformin and iodinated contrast.
