Abstract

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 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). Conclusion The 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.
