瘤体因素(T)是决定肝癌(HCC)能否切除和估计预后最重要的因素,T包括瘤体大小、肝内转移(IM)及血管受侵,包括门脉(Vp)与肝静脉(Vv)。本文前瞻性研究了CT MR,US对这些方面的评价,以明确这些检查的意义。 51例均经病理证实。男37例,女14例,45～77岁(平均61岁)。US检查46例,均使用3.5MHz凸面或线阵式探头。CT检查50例,以1cm层厚连续扫描,注射61.2％碘造影剂100ml行动态进床扫描,并行6分钟延时检查。MR以多层及多回波技术检查44例,场强
Tumor factor (T) is the most important factor determining whether liver cancer (HCC) can be removed and estimated. T includes tumor size, intrahepatic metastasis (IM) and vascular invasion, including portal vein (Vp) and hepatic vein ( Vv). This article prospectively studied the CT MR, US evaluation of these aspects to clarify the significance of these tests. All 51 cases were confirmed by pathology. There were 37 males and 14 females, 45 to 77 years old (mean 61 years old). The US examined 46 cases and all used a 3.5MHz convex or line array probe. CT examination of 50 cases, continuous scan with a thickness of 1cm, injection of 61.2% iodine contrast agent 100ml line dynamic bed scanning, 6 minute delay check. MR examination of 44 cases with multi-layer and multi-echo techniques
