Tmax >4 s volume predicts stroke recurrence in symptomatic intracranial atherosclerotic stenosis with optimal medical treatment.

Background: The time to maximum (Tmax) profile based on computed tomography perfusion (CTP) provides a quantitative assessment of cerebral hemodynamic compromise. We aimed to delineate the Tmax profile in stroke patients with symptomatic intracranial atherosclerotic stenosis (ICAS) and to investigate its predictive role in stroke recurrence after optimal medical treatment.

Methods: Consecutive patients with ischemic stroke within 30 days attributed to 50%-99% ICAS were prospectively enrolled.

Right-Sided Colonic Diverticulitis: Clinical Features, Sonographic Appearances, and Management.

Purpose: This study aims to evaluate patients with right-sided colonic diverticulitis detected at ultrasonography (US).

Methods: We retrospectively analyzed 14 patients. Demographic data, clinical features, and US images were documented.
