A proper preliminary stage is essential for determining the appropriate therapy approach for each patient. Even though controversial, computed tomography (CT) preoperative staging in colorectal cancer (CRC) may be beneficial for planning surgery and neoadjuvant treatment, especially when local tumor extension onto surrounding structures or metastatic disease is identified. CT technology has advanced significantly since the debut of the multidetector row CT (MDCT) scanner. Due to developments in CT technology, the potential usefulness of CT in the diagnosis and staging of CRC has piqued attention. In recent studies, MDCT using multiplanar reformations imaging has shown promise in identifying the local extent and nodal involvement of CRC. CT scans are useful because they give functional as well as anatomical information. As a result, it is only normal to assume that CT will improve CRC preoperative staging accuracy. The exact identification of distant metastases is the most crucial additional information provided by CT. CT offers a relative advantage over CT in the assessment of patients with CRC in terms of tumor penetration thru the walls, extracurricular expansion, and regional lymph node metastases. Patients with metastatic lesions that are suggestive but not definitive should get a CT scan.
