Imaging Modalities for Preoperative Staging of Rectal Cancer in Developing Countries : A Comparative Study of F-FDG PET/CT And MRI

Abstract

Rectal cancer represents a significant healthcare challenge globally demanding accurate pre-operative staging to guide therapeutic interventions and prognostic estimations This study aims to compare the efficacy and use of F-FDG PET CT and MRI in preoperative staging of rectal cancer in developing countries such as india Using a cross-sectional study design a total of 70 patients diagnosed with rectal cancer were prospectively enrolled and equally divided Into group A and group B For group A f- fdg PET CT and for group B MRI was conducted The primary outcome measures were accuracy sensitivity and specificity of each imaging modality in detecting local tumor extent T stage lymph node involvement N stage and distant metastasis M stage Histopathological biopsy was taken for each patient and considered as reference standard Data were analyzed using descriptive statistics and diagnostic accuracy measures
