Prompt and accurate diagnosis is critical in the treatment of acute cholecystitis. Diffusion-weighted whole-body magnetic resonance imaging with background body signal suppression/T2 image fusion (DWIBS/T2) identifies areas with high signal intensity, corresponding to inflammation. In the present study, the records and images of patients with acute cholecystitis who underwent DWIBS/T2 between January 2013 and March 2014 were retrospectively analyzed. A total of 11 patients with acute cholecystitis were enrolled. In one patient, DWIBS/T2 identified a thickened wall and high signal intensity, with high signal intensity in the pericholecystic space that suggested localized peritonitis. Positive DWIBS/T2 results indicating acute cholecystitis were obtained in 10/11 patients, with a sensitivity of 90.9%. In addition, wall thickening and high signal intensity were absent in DWIBS/T2 images when wall thickening was not detected by computed tomography. Wall thickening and high signal intensity was attenuated when patients with acute cholecystitis were clinically treated. These data suggest that a thickened gallbladder wall and high signal intensity are indicative of acute cholecystitis and that DWIBS/T2 may be a useful technique in evaluating the severity of acute cholecystitis.
及时准确的诊断对于急性胆囊炎的治疗至关重要。背景体部信号抑制/ T2图像融合的扩散加权全身磁共振成像（DWIBS/T2）可识别出与炎症相对应的高信号强度区域。在本研究中，对2013年1月至2014年3月期间接受DWIBS/T2检查的急性胆囊炎患者的记录和图像进行了回顾性分析。共纳入11例急性胆囊炎患者。在1例患者中，DWIBS/T2显示胆囊壁增厚及高信号强度，胆囊周围间隙呈高信号强度提示局限性腹膜炎。11例患者中有10例DWIBS/T2结果呈阳性，提示急性胆囊炎，敏感性为90.9%。此外，当计算机断层扫描未检测到胆囊壁增厚时，DWIBS/T2图像中也无胆囊壁增厚及高信号强度表现。急性胆囊炎患者经临床治疗后，胆囊壁增厚及高信号强度减弱。这些数据表明，胆囊壁增厚及高信号强度提示急性胆囊炎，且DWIBS/T2可能是评估急性胆囊炎严重程度的一种有用技术。
