目的探讨磁共振弥散加权成像(DWI)在卵巢囊实性良恶性肿瘤诊断中的应用价值。方法 31例卵巢良性肿瘤患者作为对照组,同期32例卵巢恶性肿瘤患者作为观察组,均行DWI扫描及核磁共振成像(MRI)扫描,比较两组囊性及实性部分的指数表观弥散系数(e ADC)及表观弥散系数(ADC)。结果两组囊e ADC、囊ADC对比,差异无统计学意义(P>0.05);观察组实e ADC(257.59±89.33)×10-3 mm~2/s高于对照组(194.39±64.30)×10-3 mm~2/s,实ADC(0.96±0.24)×10-3 mm~2/s低于对照组(1.49±0.50)×10-3 mm~2/s,差异均具有统计学意义(P<0.05)。结论 DWI对卵巢实性恶性肿瘤具有较高诊断价值。
Objective To investigate the value of magnetic resonance diffusion-weighted imaging (DWI) in the diagnosis of benign and malignant ovarian cysts. Methods Totally 31 patients with benign ovarian tumor served as the control group and 32 patients with ovarian malignant tumor as the observation group underwent DWI scan and MRI scan. The apparent diffuse coefficient (e ADC) and apparent diffusion coefficient (ADC). Results There was no significant difference in e ADC and cyst ADC between the two groups (P> 0.05). The real e ADC of the observation group was higher than that of the control group (257.59 ± 89.33) × 10-3 mm ~ 2 / s (194.39 ± 64.30) × 10-3 mm ~ 2 / s, real ADC (0.96 ± 0.24) × 10-3 mm ~ 2 / s were lower than those in control group (1.49 ± 0.50) × 10-3 mm ~ 2 / s Significance (P <0.05). Conclusion DWI has high diagnostic value in ovarian solid malignant tumors.
