结直肠癌的影像学研究进展

Imaging research progress for colorectal cancer

结直肠癌起病较为隐匿,病情发展缓慢,早期无明显的临床表现,出现明显的症状时大多已到中晚期,因此及时、准确的诊断对临床治疗及预后有重要的意义。随着影像学的迅速发展,早期并及时成功诊断结直肠癌已成为现实。目前,结肠双对比造影仍然为有价值的常用安全检查方法,超声、CT、MR对肿瘤的分期具有重要的诊断价值,18F-脱氧葡萄糖(FDG)PET/CT对结肠癌的分子影像学诊断成为可能。

With the onset of secretiveness,slow progression,atypical symptoms during the early stage,colorectal cancer showed obvious symptoms during the intermediate and advanced stage,so timely and accurate diagnosis is important for clinical treatment and prognosis.With the rapid development of imaging,early and successfully diagnosing colorectal cancer in time has become a reality.At present,colon double contrast barium enema is still a common valuable and safety inspection method.Ultrasound,CT and MRI have important values in neplasms staging.18FDG PET/CT makes the molecular imaging diagnosis of colorectal cancer to be possible.
