MR Imaging and Computed Tomography in Patients with Rectal Tumours Clinically Judged as Locally Advanced

摘要: Abstract AIM: To compare magnetic resonance (MR) imaging and computed tomography (CT) in the local staging of locally advanced rectal tumours. MATERIALS AND METHODS: Sixteen consecutive patients who, after pre-operative radio-chemotherapy (RCT), had surgery for tumours clinically judged as extending into neighbouring tissues pelvis, were examined using MR CT before treatment. The examinations reviewed by four radiologists. relation to 14 different anatomic structures pelvis a total 50 was studied. results compared surgical histopathological findings. RESULTS: Seven tumour infiltration adjacent organs at surgery, most common being urinary bladder, prostate, uterus small bowel. predicted involvement bladder better than CT. However, there more false positive findings on CONCLUSION: For cancers, overall not significantly If cannot be ruled out CT, is advocated due its higher soft tissue contrast resolution multi-planar capability.
