Gallbladder volvulus diagnosed by MRCP and diffusion-weighted imaging in an elderly woman.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Gallbladder (GB) volvulus is a rare cause of acute abdominal pain and is frequently misdiagnosed as acute cholecystitis due to its nonspecific presentation. We report an elderly woman in whom magnetic resonance cholangiopancreatography (MRCP) with diffusion-weighted imaging (DWI) enabled a timely, accurate preoperative diagnosis. An 84-year-old woman presented with acute right upper quadrant pain; inflammatory markers were normal. Ultrasound (US) and contrast-enhanced computed tomography (CT) suggested acalculous cholecystitis; CT showed a "whirl sign" but no V-shaped distortion of the extrahepatic ducts. MRCP confirmed a "whirl sign" involving the cystic duct and artery, and DWI demonstrated diffusion restriction in the GB wall, consistent with acute ischemia secondary to torsion. Laparoscopic cholecystectomy confirmed a 360° torsion with ischemic changes. This case highlights the limitations of US and the variable sensitivity of CT for GB volvulus, especially in atypical presentations. MRCP with DWI provides complementary anatomic and functional information, supporting a confident preoperative diagnosis and prompt surgical intervention.
