“…To our knowledge, this is the first report of gallbladder mucosal retraction. About 20% of intrahepatic cholangiocarcinoma show adjacent hepatic capsular retraction ( 18 ), and lung and breast cancers show retraction of adjacent normal tissue or architectural distortion ( 19 20 ); these are owing to the prominent fibrous stroma of malignant neoplasms ( 18 ). GBC originates from the mucosal layer, and fibrosis of the neoplasm retracts the adjacent gallbladder wall; therefore, it is presented as a mucosal retraction.…”

Purpose To define an MRI scoring system for differentiating xanthogranulomatous cholecystitis (XGC) from wall-thickening type gallbladder cancer (GBC) and compare the diagnostic performance of the scoring system with the visual assessment of radiologists. Materials and Methods We retrospectively analyzed 23 and 35 patients who underwent abdominal MRI and were pathologically diagnosed with XGC and wall-thickening-type GBC after surgery, respectively. Three radiologists reviewed all MRI findings. We defined a scoring system using these MRI findings for differentiating XGC from wall-thickening type GBC and compared the area under the curve (AUC) of the scoring system with the visual assessment of radiologists. Results Nine MRI findings showed significant differences in differentiating the two diseases: diffuse gallbladder wall thickening ( p < 0.001), mucosal uniformity ( p = 0.002), intramural T2-high signal intensity ( p < 0.001), mucosal retraction ( p = 0.016), gallbladder stones ( p < 0.001), T1-intermediate to high-signal intensity ( p = 0.033), diffusion restriction ( p = 0.005), enhancement pattern ( p < 0.001), and phase of peak enhancement ( p = 0.008). The MRI scoring system showed excellent diagnostic performance with an AUC of 0.972, which was significantly higher than the visual assessment of the reviewers. Conclusion The MRI scoring system showed better diagnostic performance than the visual assessment of radiologists to differentiate XGC from wall-thickening-type GBC.

“…MR images were uploaded to the picture archiving and communication system workstation (SYNAPSE (PACS), 3.1.1., Fujifilm (China) Investment Co., Shanghai, China) for image analyses. In all images, we evaluated the presence or absence of crimping of the liver capsule (flattening, or concavities of the convex border and/or focal irregularities of the liver capsule [10]), atrophy of the liver parenchyma (reduced size of the corresponding liver lobe by at least 50%), the upstream bile duct dilatation (a bile duct diameter >2 mm or the adjacent portal vein diameter > 40%), enhancement of the peribiliary liver parenchyma, the proportion of intraductal soft tissue, and tumor location. To determine intraductal tumor volume, the tumor area or area of interest was described on each imaging slice of the axial MR image.…”

Departmental sources Background:In most cases, biliary tract intraductal papillary mucinous neoplasm (BT-IPMN) is depicted by pathological features rather than on imaging modalities, but fine-needle aspiration cytology cannot provide complete information on tumor(s). Computed tomography (CT) has the advantage of high spatial resolution and multiplanar capabilities, while magnetic resonance imaging (MRI) has greater contrast resolution than CT. The purpose of this study was to compare the diagnostic performance of CT vs. MRI for the diagnosis of BT-IPMN using surgical pathology as the reference standard. Material/Methods:Data from CT, MRI, and surgical pathology of 210 patients with complaints of abdominal discomfort, vomiting, and/or jaundice for at least 6 months were included in the analysis. Intra-observer agreements for diagnosis of neoplasm was evaluated by kappa statistics. Results:CT and MRI respectively detected 171 and 33 patients with BT-IPMN, 6 and 176 with biliary intraductal tubulopapillary neoplasms (BT-ITPN), and 28 and 6 with inconclusive results. Surgical pathology reported 179 patients with BT-IPMN and 25 patients with BT-ITPN. CT and MRI both had the same accuracy (97.14%) for BT-IPMN.The sensitivities for diagnosis of BT-IPMN were 87.75%, 83.81%, and 81.43% for the surgical pathology, MRI, and CT, respectively. Intra-observer agreements for diagnosis of neoplasm were substantial (k=0.79), perfect (k=0.81), and perfect (k=0.85) for CT, MRI, and surgical pathology, respectively. Conclusions:MRI appears to be a more accurate and reliable method than CT for depicting BT-IPMN.
