Magnetic resonance is currently a key examination for rectal tumors invading through muscularis propria. The reason is accurate TNM staging and selection of appropriate treatment. The use of PET/MRI combines the possibility not only to examine the rectum and performe T staging, but it can help delineate extent of tumor better and also better characterize small lymph nodes and improve detection of distant metastases. The use of hepatospeific contrast agent improves detection and specification of the focal liver lesion. This aproach called one - stop - shop ensures to determine TNM classification in one examination. Moreover, this approach is beneficial from the patient´s point of view and it also saves examination times on other modalities and ultimately reduces the overall costs of diagnosis.

Keywords: rectal cancer, PET, MR, TNM classification.
