“…After reviewing the full text of 13 eligible articles, we excluded four for the following reasons: studies outside the field of interest (n = 3) and those with overlapping study populations (n = 2) . Ultimately, eight studies evaluating the diagnostic performance of DWI for GB lesions, including 557 patients, were included.…”

“…One study (21) used only 3T scanners, six used only 1.5T scanners, and one used both 1.5T and 3T scanners. Regarding the respiratory trigger for DWI, five studies obtained respiratory‐triggered echo‐planar DWI and two obtained non–respiratory‐triggered echo‐planar DWI. Regarding breath‐hold for DWI, one study used breath‐hold and six used free‐breathing DWI.…”

“…T1-weighted dual-echo chemical-shift MR with in-phase and out-of-phase imaging and apparent diffusion coefficient values have been used for the evaluation of XGC by some researchers [13,14]. The signal intensity of intramural nodules was higher on the in-phase image than on the out-of-phase image in 4 cases confirming fat/lipid within the wall.…”

SummaryBackgroundTo study CT and MR findings in xanthogranulomatous cholecystitis (XGC).Material/MethodsRetrospective analysis of 30 histopathologically confirmed cases of XGC. Seventeen patients underwent CECT and 13 underwent MRI. The following features were studied – wall thickness, intramural nodules, pericholecystic stranding, wall thickness, THAD, fat in gallbladder wall, cholelithiasis, infiltration, biliary dilatation, lymph nodes, complications.ResultsThe majority of cases (22/30) showed discontinuous mucosal lining. Discontinuous mucosal lining was seen in all cases with wall thickness >10 mm, 75% of cases with wall thickness between 3–10 mm and none in normal wall thickness (p=0.03). Diffuse wall thickening was seen in 23 cases, focal thickening in 3 and polypoidal wall thickening in 2 cases. Polypoidal thickening was seen in gallbladder carcinoma. Intramural nodules were present in 87.5% of cases with discontinuous mucosal lining. Pericholecystic stranding was seen in 19, biliary dilatation in 12, liver infiltration in 13 and fat in 7 cases. Lymphadenopathy was seen in 1 case with gallbladder carcinoma. Four cases showed a signal drop in the intramural nodules on chemical shift MRI.ConclusionsDiscontinuous mucosal lining is evident in xanthogranulomatous cholecystitis. Diffuse wall thickening, intramural nodules, continuous or discontinuous mucosal lining and cholelithiasis may indicate XGC rather than gallbladder carcinoma. Based on correlation with pathophysiological findings, we conclude that discontinuous mucosal lining is not an unusual finding in cases of XGC. Advances in knowledge: Being aware of the radiological findings described in this article may be helpful in making preoperative radiological diagnosis of XGC. Mucosal lining may be continuous or discontinuous in XGC.

Visually increased mural signal on high b-value DWI was highly sensitive and moderately specific for acute cholecystitis, being an independent predictor relative to conventional features for both readers. Although requiring larger studies, DWI (particularly the high b-value images) may have additive value relative to conventional MRI-suspected acute cholecystitis. J. Magn. Reson. Imaging 2016;44:89-97.
