目的探讨多层螺旋CT(MSCT)薄层增强扫描对早期胰腺癌的诊断价值。方法分析38例经手术或穿刺病理活检证实的胰腺癌的MSCT三期增强扫描资料,分析肿瘤的部位、大小、影像表现、邻近血管及脏器是否受侵等。结果38例中平扫呈低密度的21例,11例呈略低密度,6例呈等密度。增强扫描可见不均匀低于正常胰腺实质强化。结论MSCT薄层增强扫描对胰腺癌的诊断,尤其是早期诊断具有重要意义。
Objective To investigate the diagnostic value of multislice spiral CT (MSCT) thin layer contrast-enhanced scanning in early pancreatic cancer. Methods Thirty - eight cases of pancreatic cancer confirmed by surgery or biopsy were analyzed by MSCT. The location, size, imaging manifestations, invasion of adjacent blood vessels and organs were analyzed. Results Among the 38 cases, 21 cases showed low density in midline, 11 cases showed slightly low density and 6 cases showed equal density. Enhanced scan visible uneven than normal parenchymal enhancement. Conclusion MSCT thin-section enhanced scan for the diagnosis of pancreatic cancer, especially for early diagnosis of great significance.
