Abstract
Introduction: Rectal cancer is the third most common malignant disease worldwide with
a high mortality rate in developed countries ..
The magnetic resonance imaging method p lays a crucial role in the pre-operational
staging of the rectal cancer. MR is a modality of choice for rectal cancer staging, which
assists the surgeon in achieving negative resection margins.
In fact, MR assists the surgeon in the planning of the type of surgical treatment, and also
helps to predict the response to treatment and disease detection.
Material and Methods: 61 patients '\lith c'olonoscopy proven rectal cancer have been
treated treated with pre-ope_rative 1.5 T MRI of small pelvis in standard planes and pulse
sequences (SAG T2, AX Ti, T2, DWI, COR STIR)
Results: A tabular presentation of the results is given witch conelated the preoperative
MR T staging with the pathohistological finding. The comparison was made
in Tl, T2, T3 and T4 MR stadium with the acquired pathohistological stadium. The
second table showing a percentage view of the difference between MR preoperative
stadium and pathohistological results. Also a tabular presentation with general
infom1ation for patients is given ; gender , nationality and age.
Conclusion: MR as an ideal imaging method for preoperative staging for a local or
advanced stage of rectal cancer. MR allows evaluation of extramural spreading,
determines the mesorectal involvement and involves the margin of resection.
