摘　　要：目的探讨磁共振扩散加权成像在女性附件囊性肿块中的诊断价值。方法对69例经病理证实为附件囊性肿块的患者进行常规磁共振扩散加权成像扫描，分析囊性肿块不同病灶性质扩散系数值、相对信号强度值的变化。结果良性附件囊性肿块磁共振扩散加权成像扩散系数值由低到高依次为血液性病灶、脂质性病灶、脓液性病灶、黏液性病灶、浆液性病灶，不同病灶性质扩散系数值比较差异有极显著性（P〈O．01）；相对信号强度值以脓液性病灶最高，黏液性病灶其次，均显著高于血液性病灶、脂质性病灶、浆液性病灶（P〈O．01）。良性与恶性附件囊性肿块黏液和浆液性病灶扩散系数值、相对信号强度值比较差异均无显著性（P〉O．05）。结论磁共振扩散加权成像在鉴别诊断女性附件囊性肿块的类型中具有较高的应用价值，但在判断囊性肿块良恶性中还存在局限性。Objective To explore the diagnostic value of diffusion weighted imaging in female adnexal cyst- ic mass （ACM）. Methods Routine DWIs were conducted in 69 ACM patients proven by pathology, focus qualities of cystic mass, diffusion coefficient and relative signal intensity analyzed. Results The diffusion coefficient value of blood focus was the highest, then lipid, pus, myxoid and serosity focus in turn, there were very significant differences in diffusion coefficient values of different foci （P〈0.01） ; relative signal intensity of pus focus was the highest, then myxoid, and those of both foci were significantly higher com- pared with blood, lipid and serosity （P〈0.01）. There were no significant differences in diffusion coeffi- cient and relative signal intensity of myxoid and serosity focus between benign and malignant ACM （P〉0.05）. Conclusion DWI has higher application value in differential diagnosis of female ACM, but limitations in judging the benign and malignant of cystic mass.
