Core Tip
Core tip: We review recent advances in the preoperative imaging of colorectal cancer especially regarding computed tomography (CT) colonography, magnetic resonance imaging (MRI), and positron emission tomography (PET)/CT colonography. CT colonography can provide information for the preoperative assessment of T staging in colorectal cancer by morphological analysis of wall deformities. CT colonography with contrast enhancement is useful for imaging the vascular anatomy prior to laparoscopic surgery. MRI is widely used for the T staging of rectal cancer. N staging in patients with colorectal cancer is still challenging. The combination of MRI and PET/CT colonography may be useful for N staging. Gadolinium ethoxybenzyl diethlenetriamine pentaacetic acid - enhanced MRI is more accurate than CT and ultrasound for the evaluation of liver metastases.
