We compared individual computed tomography (CT) and MRI findings in differentiating acute from chronic cholecystitis. Thirty-seven patients undergoing both studies before cholecystectomy were included. Two radiologists (R1/R2) independently assessed all cases. For detecting acute cholecystitis, MRI showed better sensitivity (R1) using gallbladder wall thickening, accuracy (R1) and sensitivity (R1) using gallstones, sensitivity (R1 and R2) and accuracy (R2) using gallbladder wall hyperemia, accuracy (R1 and R2) using gallbladder wall defect, and accuracy (R2) using adjacent liver hyperemia (P=.004-.063). MRI also showed better specificity (R2) using pericholecystic fat stranding (P=.016). Overall, several findings showed better sensitivity and/or accuracy for acute cholecystitis on MRI than CT.
我们比较了计算机断层扫描（CT）和磁共振成像（MRI）在鉴别急性和慢性胆囊炎中的个体表现。在胆囊切除术前，有 37 名患者同时进行了这两项检查。两位放射科医生（R1/R2）独立评估了所有病例。对于急性胆囊炎的检测，MRI 在胆囊壁增厚（R1）、胆囊结石（R1）、胆囊壁充血（R1 和 R2）、胆囊壁缺损（R1 和 R2）、邻近肝脏充血（R2）方面的敏感度（R1）、准确度（R1）和敏感度（R1）、准确度（R2）均优于 CT（P=.004-.063）。MRI 在胆囊周围脂肪条纹（pericholecystic fat stranding）（R2）方面的特异性也更好（P=.016）。总的来说，与 CT 相比，MRI 在诊断急性胆囊炎方面具有更好的敏感度和/或准确度。
