目的探讨腹部数字减影血管造影(DSA)不同参数造影对肝癌病灶检出的影响。方法对就诊的220例肝癌患者行DSA下肝总动脉不同参数造影,对造影图像进行分析并对检出病灶在大小及数量方面进行测量统计。结果220例病例中,140例在2种参数下造影检出病灶数相同,80例出现病灶染色差异。对220例病人行常规造影(routine angiography,RA)共检出病灶562个,病灶直径最小0.8 cm;行长时间低流率造影(long tim e low rate angiography,LTLRA)共检出病灶691个,最小0.3 cm。结论经肝总动脉长时间低流率造影较常规参数造影可大大提高病灶检出率,特别是对血供不丰富及较小病灶的检出更有意义。
Objective To investigate the effect of different parameters of abdominal digital subtraction angiography (DSA) on detection of liver cancer lesions. Methods 220 patients with hepatocellular carcinoma treated under DSA under different parameters of the common hepatic artery angiography, angiography images were analyzed and the detection of lesions in size and number of measurement statistics. Results Of the 220 cases, 140 cases had the same number of lesions detected by two kinds of parameters and 80 cases showed lesions. A total of 562 lesions were detected by routine angiography (RA) in 220 patients, with a minimum diameter of 0.8 cm. A total of 691 lesions were detected in long tim e low rate angiography (LTLRA) Minimum 0.3 cm. Conclusion Long-term low-rate contrast-enhanced MR angiography can greatly improve the detection rate of lesions, especially for detection of lesser blood supply and smaller lesions.
