Core Tip
Core tip: In rectal cancer, accurate staging and circumferential resection margin assessment are essential for stratifying the risks of recurrence and determining the optimal therapeutic strategy for individual patients. In the preoperative setting, a combination of multimodal imaging methods, including endorectal ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI), can be used to precisely assess the preoperative staging of rectal cancer. However, restaging after neoadjuvant therapy remains a challenge with all of these modalities. Recently, high-resolution MRI with diffusion-weighted imaging and/or positron emission tomography-CT imaging methods have been developed to precisely assess the restaging of rectal cancer following neoadjuvant chemoradiation therapy.
