摘要
目的：探讨自动乳腺全容积成像系统（ABVS）在小腿肌间静脉血栓诊断中的应用价值。方法：首先对539例临床疑诊下肢静脉血栓高危患者应用ABVS采集容积数据，其次分别由2位超声医师同时双盲进行容积数据阅片及常规彩色多普勒超声（Hand-held ultrasonography，HHUS）检查，ABVS检出所有病灶均由HHUS二次复诊以确诊，最后比较两种检查方法的检出率。结果：①539例患者中HHUS初次诊断68例（共112侧患肢、122处病灶），ABVS初次诊断86例（共141侧患肢、172处病灶）。②ABVS补充及纠正HHUS初次诊断17例（共27侧患肢、42处病灶），占19.4%（27/139）。HHUS及ABVS检出率分别为10.4%（112/1 078）和12.9%（139/1 078），两种方法检出率差异有统计学意义（P=0.00）。③ABVS与HHUS对小腿肌间静脉血栓单发病灶与多发病灶的检查率差异有统计学意义（P=0.02）。结论：ABVS能够多平面显示小腿后肌群，尤其在冠状面能够直观显示病灶，可提高超声对小腿肌间静脉血栓的检出率，特别是多发病灶。
Abstract
Objective: To study the value of automated breast volume scanner(ABVS) in calf muscular venous thrombosis. Methods: Five hundred and thirty-nine patients were subjected to an ABVS examination in the supine position, and data were automatically sent to the ABVS workstation. And then diagnosis of lesions with the volume data and hand-held ultrasonography(HHUS) by two radiologists independently and blindly. Detection rate predictive value of each method were analysed. Results: ①The number of lesions initially detected by ABVS were 86 patients(including 141 limbs, 172 lesions) and 68 by HHUS were patients(including 112 limbs, 122 lesions). ②ABVS discovered additional new findings and corrected the diagnosis in 17 patients(including 27 limbs, 42 lesions). The detection accuracy of HHUS and ABVS were 10.4%(112/1 078) and 12.9%(139/1 078) respectively. McNemar test showed statistically significant(P=0.00) in detection accuracy. ③There was statistical significance(P=0.00) in single and multitudinous lesions of detection accuracy by ABVS and HHUS. Conclusions: Automated breast volume scanner provides advantages of visualization of the whole calf muscular, especially in the coronal plane of ABVS, which can enhance the detection rate of ultrasound in the diagnosis of calf muscular venous thrombosis.
