Comparison of Diagnostic Performance between Perfusion-Related Intravoxel Incoherent Motion DWI and Dynamic Contrast-Enhanced MRI in Rectal Cancer

Figure 1

A 48-year-old woman with rectal adenocarcinoma was performed by IVIM and DCE. (a) High-resolution oblique axial T2W showed intermediate-signal intensity lesion (white arrow). (b) DWI (b = 1000 s/mm²) showed a hyperintensity lesion (white arrow). (c) ADC map showed a hypointensity lesion (white arrow). (d) DCE-MRI showed an abnormal enhanced lesion (white arrow). (e) ROI was manually drawn to cover as much of the entire tumor area as possible (white circle).
