摘要
直肠癌是消化道常见的恶性肿瘤。壁外血管侵犯(EMVI)是直肠癌危险分层的关键指标,也是决定个体化治疗方案的重要参考因素,故术前准确评估壁外血管是否被肿瘤浸润非常重要。直肠癌主要影像学检查方法包括磁共振成像(MRI)、电子计算机断层扫描(CT)及经直肠腔内超声检查(TRUS),本文重点分析上述成像方法在直肠癌EMVI方面的表现及诊断效能,为临床提供参考。
Rectal cancer is a common malignancy of the gastrointestinal tract.Extramural vascular invasion(EMVI)is a key indicator of risk stratification for rectal cancer and an important reference factor in determining individualised treatment options,so it is important to accurately assess whether extramural vessels are infiltrated by the tumour before surgery.The main imaging methods for rectal cancer include magnetic resonance imaging(MRI),computed tomography(CT)and transrectal ultrasound(TRUS).This article focuses on the performance and diagnostic efficacy of these imaging methods in the diagnosis of EMVI in rectal cancer,and provides clinical reference.
