Fig. 3From: Role of diffusion-weighted MRI in diagnosis and post therapeutic follow-up of colorectal cancerFifty-four-year-old female presented with constipation and bleeding per rectum. Colonoscopy and biopsy revealed rectal moderately differentiated adenocarcinoma. A Large lobulated circumferential soft tissue mass (measured 9 × 5 × 6.7 cm) was seen infiltrating the upper and middle thirds of rectum with anteriorly exophytic component invading the posterior wall of uterine cervix, best appreciated in sagittal T2-weighted image (A). It displayed heterogeneous high signal in T2WI (B) and intermediate signal in T1WI (C), with heterogeneous enhancement in post contrast images (D). The lesion appeared bright in DWIs (E) and turned dark in the ADC map (F), with ADC value 1.0 × 10−3 mm2/s, indicating restricted diffusionBack to article page
