A-MRI comprised diffusion-weighted imaging (DWI) and T2-weighted imaging of the upper abdomen and the pelvic cavity. Three radiologists independently reviewed A-MRI, CECT, and standard liver MRI in the detection of viable disease. The diagnostic performances were compared using a reference standard considering all available information, including pathology, FDG-PET, endoscopic results, and clinical follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We included 78 patients (50 men, 28 women; mean age=60.9\u2009\u00b1\u200910.2 years) and observed viable disease in 34 (43.6%). On a per-patient-basis analysis, A-MRI showed significantly higher sensitivity (95% vs. 81%, P\u2009=\u20090.04) and higher accuracy (93% vs. 82%, P\u2009&lt;\u20090.01), compared to those of CECT, while A-MRI showed comparable sensitivity (91% vs. 91%, P\u2009=\u20090.42) and accuracy (97% vs. 98%, P\u2009=\u20090.06) to that of standard liver MRI. On a per-lesion-based analysis, A-MRI exhibited significantly superior lesion detectability than that of CECT (figure of merit 0.91 vs. 0.77, P\u2009&lt;\u20090.01) and comparable to that of standard liver MRI (figure of merit 0.91 vs. 0.92, P\u2009=\u20090.75).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A-MRI exhibited higher sensitivity and diagnostic accuracy than those of CECT in the post-treatment evaluation of RC, while it showed comparable performances with standard liver MRI.
