iZoom applying tilted 2D Echo-Planar RF excitation improved the image quality of reduced FOV DWI for uterine cervical cancer: a preliminary study

Reduced field-of-view (rFOV) DWI is the essential sequence for the diagnosis and staging of uterine cervical cancer (CC). We compared the image quality of rFOV DWI taken with iZoom, which applies tilted 2D Echo-Planar RF excitation, and that of conventional Zoom combined with Reconstruction with Image-space Sampling (Zoom-IRIS) for CC patients. Reduced FOV DWI with iZoom showed higher image quality than Zoom-IRIS both in quantitative and qualitative evaluation. Anatomical details display and lesion conspicuity were mainly improved in quantitative evaluation. iZoom can be helpful for the diagnosis and staging of CC.
