肝脏占位性病变三维超声诊断价值

Diagnostic Value of Three-dimensional Ultrasonud in Space-Occupying Hepatic Lesions

对60例肝脏占位性病变的三维超声成像进行探讨。其中原发性肝癌23例,肝血管瘤17例,肝囊肿16例,转移性肝痛4例。结果:三维成像显示的病变侵犯区域、空间位置、肿块内部结构、边界边缘状态均优于二维超声显像,优于后者的例数分别为51例(85.0％)、44例(73.3％)、41例(68.3％)、39例(65.0％)。该4项指标全部优秀者三维为38例(69.3％),二维为24例(40.0％),两组相比差异有显著意义(x^2=128.065,P<0.005)。两组成像诊断与病理、CT和MR的诊断符合率三维为59例(98.3％),二维41例(68.3％),两组相比差异也有显著性(x^2=100.36,P<0.005)。综上可见,三维成像的质量和临床诊断价值,明显优于二维成像。

Three-dimensional ultrasound reconstruction (3-DUR)technique was used for diagnosing 60 cases with space-occupying hepatic lesion,in which there were 23 cases of primary liver cancer, 17 cases of hepatic hemangiona,16 cases of liver cyst,4 cases of metastatic carcinoma. The displaying rates of infil-trative area, occupied space, internal structure and contour of the lesion in image presented by 3-DUR were 85% (51/60) ,73% (44/60) ,68. 3%(41/60)and 65%(39/60)respectively. It is superior to 2-Das a whole and provides more information for clinical diagnosis.
