本文主要进行了临床41例病人动脉门脉造影CT（CTAP）技术检出小肝癌（直径＜3．0cm）和微小肝癌直径≤1．5cm）的敏感性研究，同时与其它影像诊断技术进行比较。全部病例同时作了常现二维超声（US），平扫CT（PCT）和增强CT（CCT）；15例经手术清理证实的肝癌患者又作了动态增强CT（DI－CT）和4h延迟CT（DCT）8其余26例未手术的肝癌患者作了碘油CT（IO－CT）和肝动脉造影（HAA），其中10例病人再作了磁共振成像（MRI）检查。结果表明：它们检出小肝癌的敏感性分别为：CTAP94．1％（48／51）、US43．1％（22／51）、PCT43．1％（22／51）、CCT54．9％（28／51）、DI－CT57．1％（12／21）、DCT57．1（12／21）、IO－CT63．3％（19／30）、HAA70％（21／30）、MRI63．2％（12／19）；检出微小肝癌的敏感性分别为：CTAP90．9％（20／22）、US13.6（3／22）、PCT9．1％（2／22）、CCT22．7％（5／22）、DI－CT25％（2／8）、DCT25％（2／8）、IO—CT50％（7／14）、HAA57．1（8／14）、MRI50％（4／8）。行统计学检验CTAP与其它各种影像诊断技术有差别（P＜0.05），但进一步作统计学分析发现肿瘤直径在1．5～3。0cm间的病灶，CTAP除与US和PCT有差异外（P＜0．05），同其它影像诊断技术无差别（P＞0．05）。?
This article mainly carried out the clinical study of 41 cases of clinical arterial portography CT (CTAP) technology to detect the sensitivity of small hepatocellular carcinoma (<3.0cm in diameter) and tiny hepatocellular carcinoma diameter ≤1.5cm, and compared with other imaging diagnostic techniques. . In all cases, two-dimensional ultrasound (US), plain CT (PCT) and contrast-enhanced CT (CCT) were performed at the same time. Dynamic contrast-enhanced CT (DI-CT) and 4h delay were also performed in 15 cases of liver cancer patients confirmed by surgery. The remaining 26 cases of untreated liver cancer patients with CT (DCT)8 were treated with lipiodol CT (IO-CT) and hepatic artery angiography (HAA). Magnetic resonance imaging (MRI) was performed in 10 patients. The results showed that: The sensitivity of their detection of small hepatocellular carcinoma were: CTAP 94.1% (48/51), US 43.1% (22/51), PCT 43.1% (22/51), CCT 54.9% (28 /51), DI-CT57.1% (12/21), DCT57.1 (12/21), IO-CT63.3% (19/30), HAA70% (21/30), MRI 63.2% ( 12/19); The sensitivity of detection of micro HCC was: CTAP 90.9% (20/22), US13.6 (3/22), PCT9.1% (2/22), CCT 22.7% (5 /22), DI-CT25% (2/8), DCT25% (2/8), IO-CT50% (7/14), HAA57.1 (8/14), MRI50% (4/8). The statistical test of CTAP was different from other diagnostic imaging techniques (P<0.05), but further statistical analysis revealed that lesions with a tumor diameter of 1.5-3.0% had a difference in CTAP except US and PCT. (P<0.05), no difference with other imaging diagnostic techniques (P>0.05). ?
