PICTORIAL REVIEW OF RECTAL CARCINOMA: A SINGLE CENTRE MRI EXPERIENCE IN SASMEC @IIUM Wan Ahmad Firdaus Wan Chek1, Raihanah Haroon2 1Radiology Department, Kulliyyah of Medicine, IIUM [e-mail] 2Radiology Department, Kulliyyah of Medicine, IIUM [e-mail] *Corresponding author: e-mail@[e-mail]; Tel : [phone] Received date: Accepted date: Published date: Abstract: Colorectal cancer is known as the third most common cancer in men and second most common in women after breast cancer worldwide. Tumour infiltration into the mesorectum and the ability to achieve negative circumferential resection margin via surgery are directly related to its prognosis. Two advanced development in the cure of rectal cancer are total mesorectal excision (TME) and neoadjuvant chemoradiotherapy. MRI plays a crucial role as the most accurate and powerful device in evaluating rectal cancer patient to select the proper and optimal treatment. High-spatial-resolution T2-weighted imaging has been the most important MRI sequence in the evaluation of rectal cancer and its surrounding anatomic structures. Using a 3.0T MRI scanner, we use TNM staging at our center which involves 57 patients with rectal adenocarcinoma. We focused on the T and N staging as MRI readily evaluates only these two components. There were 57 patients who underwent MRI rectum staging at our center resulting in 1 patient with T1 (1.7%), 2 patients with T2 (3.5%), 11 patients with T3 (19.3 %) and 43 patients with T4 (75.4%) diseases. This poster offers a pictorial review of the anorectal anatomy of rectal carcinoma in different TNM stages based on MRI evaluation. Keywords: rectal carcinoma, mri local staging
