高频探头对白内障声像图分型的探讨

本文应用１０ＭＨｚ高频探头检测２８例４８眼白内障患者，经临床特殊检查和手术病理证实。Ｂ超检出４４眼，总符合率为９１．７％（４４／４８）。４４眼晶体声像图表现可分为三型：皮质型、核型和完全型（混合型）。Ｂ超对核型和完全型（混合型）诊断符合率为１００％，皮质型有４例假阴性（１１％）。本文对各型声像图表现及假阴性作了研究与探讨。

Study on Sonographic Patterns of Cataract by 10MHz High Frequency Probe

Using 10MHz high Frequency probe,48 cataract eyes of 28cases were examined,all cases were confirmed by special clinical examines operation and pathology.The accuracy of sonography diagnosis was 91.7%.The ultrasaund appearences of lens were classified into three patterns:cortical,nuclear and complete(mixed).Both the accuracy of nuclear and complete cataract were 100%,that of cortical was 89%,4 cases of cortical being false negative,All patterns of cataract sonography were studies and false negative results of sonography were analysed and discussed.
