目的：探讨多层螺旋 CT 静脉成像(MSCTV)技术在下肢静脉栓塞疾病中的临床应用价值。方法对临床高度怀疑下肢静脉血栓疾病的28例患者进行 MSCTV,其中行直接造影法10例,间接造影法18例,5例先后行直接造影法与间接造影法,病例扫描并获得原始数据处理后传送至工作站,经血管三维重建,从而得到清晰而满意的诊断图像,总结影像学表现,结合数字减影血管造影(DSA)进行对比分析。结果28例中未见异常9例,下肢静脉栓塞19例,其中左侧下肢静脉栓塞10例,右侧下肢静脉栓塞7例,双侧同时受累2例,下肢静脉均能够清晰显影,满足对病变部位、范围及大小的诊断要求,以 DSA 为金标准,MSCTV 对下肢深静脉血栓的敏感度为95%,特异度为100%。结论 MSCTV 静脉成像技术可作为诊断下肢静脉血栓疾病的首选检查方法。

Objective To evaluate diagnostic value of multi-slice spiral CT venography(MSCTV)in detecting venous thrombosis of lower extremity.Methods We investigated 28 patients with highly suspected deep venous thrombosis for MSCTV,of which 10 cases of direct imaging method,indirect imaging method in 18 cases,5 cases successively underwent angiography direct and indirect imaging method.After the case is scanned and processed to obtain the raw data transmitted to the workstation via a three-dimension-al reconstruction of blood vessels,resulting in a clear and satisfactory diagnostic images,summarizes imaging findings,combined with digital subtraction angiography (DSA)were analyzed.Results Among 28 patients,there were 9 cases in normal,1 9 cases of deep vein thrombosis,thrombosis of lower extremity vein in 1 9 cases(lefe in 10,right in 7,both in 2 cases),and deep vein throm-bosis can be clearly detected,meeting the equirements to the diagnosis of scope and size of the lesion site.DSA as the gold standard, MSCTV deep venous thrombosis with a sensitivity of 95% and a specificity of 100%.Conclusion MSCTV may be used as the first choice in diagnosing venous thrombosis of the lower extremity.
