摘要
目的:探讨多排螺旋CT平扫及增强扫描在富血供肝转移瘤中的影像表现及诊断价值。材料与方法:回顾性分析21例富血供肝转移瘤的CT平扫及动脉期、门脉期、延迟期强化扫描资料。结果:21例共174个病灶,单发1例,多发20例,病灶直径0.9cm―7.3cm。病灶位于肝左叶54个,肝右叶120个。形态类圆形158个,不规则形16个。174个病灶中,平扫发现128个病灶,约占73.6%,呈低密度106个,等密度46个,高密度22个,其中病灶内钙化3例,共16个病灶。多期增强扫描中,174个病灶,动脉期呈高密度168个,呈等密度6个。门脉期呈高密度103个,呈等密度27个,低密度44个。延迟期呈高密度69个,等密度20个,低密度85个。174个病灶中,呈环形强化126个,结节状强化48个。21例中3例病灶推压邻近血管,7例引起邻近肝包膜局限隆起,21例中11例合并淋巴结转移或/和其他部位的转移。结论:多排螺旋CT多期增强扫描对富血供肝转移瘤病灶的检出及诊断具有重要的价值。
Purpose： To explore multi-slice spiral CT plain scan and enhanced scan in the diagnosis of hypervascular liver metastasis and imaging findings. Materials and Methods： 21 cases of CT of rich blood analysis for hepatic metastasis of scanning and arterial phase, portal venous phase, delay phase enhanced scan data. Results： a total of 21 cases with 174 le- sions, 1 cases with single lesion, 20 Cases multiple, diameter of 0. 9CM to 7.3cm. 54 lesions were located in the left hepatic lobe, the right lobe of the liver 120. Morphology of round 158, 16 irregular shape. 174 lesions, scan 128 lesions were found, accounting for about 73.6%, low density was 106, density 46, high density of 22, including 3 cases of calcification, a total of 16 lesions. Multi phase enhanced scanning, 174 lesions, the arterial phase with high density was 168, density 6. Portal ve- nous phase with high density was 103, density 27, low density 44, delay period showed a high density of 69, density 20, low density 85, 174 lesions showed ring enhancement, 126, nodular enhancement in 48, in 21 cases, the lesions of 3 cases push- ing nearby blood vessel, 7 cases were caused by adjacent liver capsule protruded, metastasis of 21 cases in 11 cases with lymph node metastasis or / and other parts of the. Conclusion： multi slice spiral CT scan is of important value in detection and diagnosis of hypervascular liver metastasisfoci.
