Primary rectal cancer local staging

MRI in local staging of rectal cancer: an update.

Preoperative imaging for staging of rectal cancer has become an important aspect of current approach to rectal cancer management, because it helps to select suitable patients for neoadjuvant chemoradiotherapy and determine the appropriate surgical technique. Imaging modalities such as endoscopic ultrasonography, computed tomography, and magnetic resonance imaging (MRI) play an important role in...

Preoperative staging of rectal cancer.

Detailed preoperative staging using high resolution magnetic resonance imaging (MRI) enables the selection of patients that require preoperative therapy for tumour regression. This information can be used to instigate neoadjuvant therapy in those patients with poor prognostic features prior to disturbing the tumour bed and potentially disseminating disease. The design of trials incorporating MR...

Optimal imaging staging of rectal cancer

A patient diagnosed with rectal cancer is managed by a multidisciplinary team in which the radiologist nowadays participates as a full sparring partner. His/her imaging findings can influence the treatment decision-making. The local staging work-up consists of endorectal ultrasound and/or magnetic resonance imaging (MRI). The distant staging work-up depends on the local policy but often consist...

Ultrasound Methods for Lower Rectal Cancer Staging

For ERUS the patient is prepared with an enema 2h before the study. ERUS is performed in the left lateral decubitus position and always starts with digital examination. Usually no sedation or general anesthesia is needed and the procedure is well tolerated by the patients. After a digital rectal examination is performed the probe covered with a balloon is inserted into the rectum. For better ac...
