摘要
目的探讨NSM-S15超导磁共振成像系统在诊断附件肿块中的诊断价值。方法选择经手术病理证实42例66个附件肿块,分别采用MRI与B超检查,以手术病理检查结果为金标准,比较MRI与B超在诊断效能。结果 66枚附件肿块中,良性肿块48枚,恶性肿块18枚;良性肿块中多表现为T1WI/T2WI高信号,恶性肿块T1WI多表现为低/等高信号;MRI诊断灵敏度、特异度、准确度、阳性预测值、阴性预测值均明显高于B超(94.44%vs 72.22,95.83%vs 89.58%,95.45%vs 84.85%,89.47%vs 72.22%,97.87%vs 89.58%),差异有统计学意义(χ2=2.758-7.775,P<0.05)。结论 NSMS15超导磁共振成像系统在诊断附件肿块中具有明显的比较优势,其诊断价值有待于进一步的开发。
Objective To study the diagnostic value of NSM-S15 superconducting magnetic resonance imaging system in the diagnosis of adnexal masses. Methods A total of 42 cases（66 appendix masses） accepted MRI and ultrasonography examination. And the surgical pathological result was the gold standard. MRI and ultrasound diagnosis effectiveness was compared. Results Results A total of 66 appendix masses, 48 were benign, and 18 were malignant, benign masses showed high signal on T1W1/T2W1, malignant masses showed low/high signal on T1WI; MRI diagnosis sensitivity, specific, accuracy, positive predictive value, negative predictive value were significantly higher than that B ultrasonic（94.44% vs 72.22, 95.83% vs 89.58%, 95.45% vs 84.85%, 89.47% vs 72.22%, 97.87% vs 89.58%）, the difference was statistically significant（χ2=2.758-2.758, P〈0.05）. ConclusionlusionThe NSM-S15 superconducting magnetic resonance imaging system has obvious comparative advantage in the diagnosis of adnexal masses,and the diagnostic value should be further developed.
