Role of Magnetic Resonance Imaging in Staging Rectal Carcinoma
Journal Title: International Journal of Anatomy Radiology and Surgery - Year 2017, Vol 6, Issue 2
Abstract
Introduction: Recent advances in management of rectal cancer have lead to emphasis on accurate preoperative staging, determination of Circumferential Resection Margin (CRM) and mesorectal fascia involvement. Because of superior soft tissue contrast and multiplanar capability, MRI is currently imaging modality of choice. Aim: To study imaging characteristics of different rectal tumors. To evaluate accuracy of MRI in local ‘T’ staging of rectal tumor. Determination of CRM and mesorectal fascia involvement and to evaluate accuracy of MRI in nodal (N) staging. Materials and Methods: A prospective study of 64 patients presenting with rectal mass/bleeding was conducted in Department of Radiodiagnosis at tertiary care hospital in Goa (Goa Medical College), over a period of 2 year by using 1.5 Tesla superconductive unit. Results: Overall accuracy of MRI for ‘T’ staging was 95.75%, the accuracy was 97.49% for T1 tumor, 94.11% for T2 tumor, 91.66% for T3 tumor and 100% for T4 tumor. MRI was 100% accurate in diagnosing mesorectal fascia invasion. Conclusion: MRI is currently the only modality that enables accurate evaluation of tumor extent, involvement of CRM and mesorectal fascia. This enables to carefully select those patients who will benefit from neo-adjuvant chemotherapy or primary surgery
