Abstract:

Purpose. Was to estimate the efficiency of MRI in specified diagnostics of colorectal cancer (CRC) local spread (distal parts of a rectum anc anal channel cancer). To develop diagnostic criteria of tumor local spread, lymph nodes' lesion and involvement of surrounding tissues and organs.

Materials and methods. Research included 25 patients with verified CRC. For specificied diagnostics of cancer local spread patients underwent MRI before and after paramagnetic contrast enhanced. All researches were spent on magnetic-resonance tomography platform GE Signa 1,5T.

Results. We have revealed and studied all the types of CRC local spread in connection with TNM classification due to MRI.

Conclusion. MRI gives the full information about tumor local spread. Application of paramagnetics gives additional information about expression degree of invasive process. MRI is effective technique as a diagnostic procedure during preoperative preparation.
