The capabilities of computed tomography (CT), ultrasonography (US), and magnetic resonance (MR) imaging were studied in order to determine the role of each of these noninvasive examinations for estimating the T-factor of hepatocellular carcinomas (HCCs). Fifty-one patients with surgically proven HCCs received CT (50 patients), US (46 patients), and MR (44 patients). The images of CT, US, and MR were prospectively evaluated for main tumor size, intrahepatic metastases, and vascular invasion, which compose the T-factor of HCC, and compared to pathological results. The sizes of the main tumor were estimated correctly by all examinations. For estimating intrahepatic metastases, US (74%) and MR (73%) were superior to CT (65%). For estimating portal invasion, CT (79%) was superior to US (70%) and MR (66%), because CT could demonstrate the segmental staining caused by portal invasion. The estimates of hepatic venous invasion were difficult during any of the examinations. We conclude that presurgical evaluations of the T-factor require the use of US and CT or MR and CT.
为了确定计算机断层扫描（CT）、超声检查（US）和磁共振成像（MR）在评估肝细胞癌（HCC）T分期中的作用，我们对这些非侵入性检查的能力进行了研究。51例经手术证实的HCC患者接受了CT检查（50例）、US检查（46例）和MR检查（44例）。对CT、US和MR图像进行前瞻性评估，以确定构成HCC T分期的主要肿瘤大小、肝内转移和血管侵犯情况，并与病理结果进行比较。所有检查都能正确估计主要肿瘤的大小。在估计肝内转移方面，US（74%）和MR（73%）优于CT（65%）。在估计门静脉侵犯方面，CT（79%）优于US（70%）和MR（66%），因为CT能够显示由门静脉侵犯引起的节段性染色。在任何检查中，肝静脉侵犯的估计都很困难。我们得出结论，术前对T分期的评估需要联合使用US和CT或MR和CT。
