BACKGROUND AND OBJECTIVE
The aim of this study was to evaluate the efficacy of DWI in differentiation of patients with residual cavity and type 1 hydatid cyst (HC) in the liver.
METHODS
32 patients were included. 12 of these patients had type 1 HC and the remainders (n = 20) had postoperative residual cavities. In all patients, axial T2-weighted and DWI images were obtained. An apparent diffusion coefficient (ADC) map of the images was automatically generated and the ADC values were measured on this map for all patients. Mann-Whitney U test was used for comparison of continuous variables between two groups.
RESULTS
The mean diameters of type 1 hydatid cyst and residual cavity groups were 83.42 mm, 49.30 mm, respectively (P = 0.001). There were no significant differences in gender and age between the groups (both P > 0.05). The mean ADC values of type 1 hydatid cyst and residual cavity groups were 2.58 ± 0.13 × 10(-3) s/mm(2), 2.58 ± 0.16 × 10(-3) s/mm(2), respectively (P = 0.953).
CONCLUSION
DWI might not be suitable to differentiate the postoperative residual cavity from the type 1 hydatid cyst in the liver due to similarity of ADC values between postoperative residual cavity and type 1 hydatid cyst.
背景与目的
本研究旨在评估弥散加权成像（DWI）在鉴别肝脏残余腔隙与1型肝包虫囊肿（HC）患者中的疗效。
方法
纳入32例患者。其中12例患者患有1型HC，其余20例有术后残余腔隙。所有患者均获取了轴位T2加权像和DWI图像。自动生成图像的表观扩散系数（ADC）图，并在该图上测量所有患者的ADC值。采用曼-惠特尼U检验比较两组间的连续变量。
结果
1型肝包虫囊肿组和残余腔隙组的平均直径分别为83.42mm、49.30mm（P = 0.001）。两组间性别和年龄无显著差异（P均>0.05）。1型肝包虫囊肿组和残余腔隙组的平均ADC值分别为2.58±0.13×10⁻³s/mm²、2.58±0.16×10⁻³s/mm²（P = 0.953）。
结论
由于术后残余腔隙与1型肝包虫囊肿的ADC值相似，DWI可能不适用于鉴别肝脏术后残余腔隙与1型肝包虫囊肿。
