摘要
应用ＣＤＦＩ检查３５例四肢软组织肿块（简称ＳＴＭＥ），其中良性肿块２５例，恶性肿块１０例。结果显示：①以肿块血流信号丰富程度分级，恶性肿块属０、１级占２０％（２／１０）（良性肿块占６２．５％，１０／１６），属２、３级占８０％（８／１０）（良性肿块占３７．５％，６／１６）。②恶性肿块组动脉峰值流速Ｖｓ＝０．７７＋０．２３ｍ／ｓ，显著高于良性肿块组（０．３１±０．１２ｍ／ｓ）（Ｐ值＜０．０１）。③恶性肿块组动脉阻力指数ＲＩ＝８１．１２％±６．００％，也显著高于良性肿块组（６５．５０％±１２．９０％）（Ｐ值＜０．０１）。以Ｖｓ≥０．５ｍ／ｓ或／和ＲＩ≥７５％作为良恶性肿块判断标准，则两维超声（２Ｄ）结合ＣＤＦＩ提高了对ＳＴＭＥ良恶性肿块判断的敏感性、特异性和准确性，其诊断准确性由单纯２Ｄ的６１．５％（１６／２６）提高到９２．３％（２４／２６）和８０．８％（２１／２６）（Ｐ值＜０．０５）。
Thirtyfive patients with soft tissue masses in extremity (STME) were studied by CDFI, including 10 malignant and 25 benign masses. The results showed: ①According to the grades of blood flow signal in masses: 20% (2/10) malignant and 62.5% (10/16) benign masses belonged to 0 and 1 grade, 80% (8/10) malignant and 37.5%(6/16) benign masses belonged to 2 and 3 grade. ②The peak flow velocity (Vs) in malignant masses was higher (0.77±0.23 m/s) than those in benign masses (0.31±0.12m/s) (P<0.01). ③The resistance index (RI) in malignant was higher (81.12±6.00%) than that in benign masses (65.50±12.90%)(P<0.01). Combining 2D with CDFI, with Vs≥0.5 m/s or/and RI≥75% as criteria for differential diagnosis, the sensitivity, specificity and the accuracy of diagnosis in malignant or benign STME are greatly improved. The accuracy rate of diagnosis for STME increased from 61.5% by 2D alone to 92.3% and 80.8% when combined with CDFI (P<0.05).
