The aim of this review is to provide an update on important recent advances in radiologic colorectal imaging, with emphasis on detection, staging, and surveillance of colorectal neoplasia.
Colorectal imaging advances with magnetic resonance (MR), computed tomography colonography (CTC), and positron emission tomography (PET) over the past year or so have been substantial. Progress in MRI for rectal cancer was most notable in terms of assessment of response to neoadjuvant therapy. Continued maturation and clinical validation of CTC was observed for the evaluation of advanced neoplasia, among other areas. Multimodality approaches to colorectal imaging that incorporate functional PET data have also made impressive strides forward.
Recent advances in cross-sectional and functional radiologic imaging of the colorectum will positively impact the clinical capabilities for noninvasive evaluation of colorectal neoplasia.
本综述旨在提供近期放射学结直肠成像重要进展的最新信息，重点关注结直肠肿瘤的检测、分期和监测。
在过去一年左右的时间里，磁共振成像（MR）、计算机断层扫描结肠成像（CTC）和正电子发射断层扫描（PET）在结直肠成像方面取得了重大进展。在评估直肠癌对新辅助治疗的反应方面，MRI的进展最为显著。在评估晚期肿瘤等领域，CTC持续成熟并得到临床验证。结合功能性PET数据的结直肠成像多模态方法也取得了令人瞩目的进展。
结直肠横断面和功能性放射学成像的近期进展将对结直肠肿瘤的无创评估临床能力产生积极影响。
