“…CT has been used widely for preoperative assessment of disseminated disease but its role in local staging is limited with reported accuracies ranging from 33 to 82% [10,11] . In a recent meta-analysis of 78 studies in 4,897 patients with rectal cancer, CT showed an accuracy of 73% for T staging [12] .…”

Carcinomas of the rectum are associated with a significant local and distant recurrence rate. Not all patients are appropriate candidates for preoperative radiation therapy. Preoperative identification of those most likely to benefit from neoadjuvant therapy is important. There is no general consensus on the role of endorectal ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) in staging patients with rectal cancer. Although the tumor stage is an important prognostic factor, preoperative assessment is associated with prediction of the circumferential resection margin. Newer developments such as coils, sequences and gradients in MRI, evolution of multidetector CT and new contrast media, allow for an algorithm selection aiming at the best diagnostic options for patients. The present review will discuss the current role of the various imaging modalities in staging carcinomas of the rectum.

“…However, early transmural bowel extension cannot be accurately predicted by CT [31]. There is evidence that CT overstages tumors and that it understages as many as 23% of tumors [32]. Transrectal ultrasonography is the state-of-the-art imaging technique in rectal cancer.…”

“…However, the distinction between malignant or inflammatory fixation is still questionable. Staging of rectal cancers with CT is therefore not recommended although it may be helpful for advanced lesions [21,55].…”
