Comparative Effectiveness of MRI with Diffusion Weighted Imaging Versus Other Imaging Modalities in Staging and Monitoring Rectal Carcinoma

EasyChair Preprint 14156

Abstract

Rectal carcinoma, a significant cause of cancer-related morbidity and mortality, requires precise staging and monitoring to guide therapeutic decisions and assess treatment response. This study evaluates the comparative effectiveness of Magnetic Resonance Imaging (MRI) with Diffusion Weighted Imaging (DWI) against other imaging modalities in staging and monitoring rectal carcinoma. A comprehensive analysis of existing literature and clinical trials was conducted to assess the sensitivity, specificity, accuracy, and prognostic value of MRI with DWI compared to computed tomography (CT), endorectal ultrasound (ERUS), and positron emission tomography (PET). The results indicate that MRI with DWI offers superior soft-tissue contrast resolution and more accurate assessment of tumor depth and nodal involvement. Additionally, DWI enhances the detection of residual or recurrent disease post-treatment, providing critical information for tailored therapeutic strategies. The findings suggest that MRI with DWI is a highly effective imaging modality for the comprehensive management of rectal carcinoma, potentially improving patient outcomes through more accurate staging and vigilant monitoring. Further research and longitudinal studies are recommended to validate these findings and integrate advanced imaging techniques into standardized care protocols.
