The performance of reduced FOV DWI, reading-segmented echo-planar DWI and conventional single-needle (ss)-EPI DWI techniques in the diagnosis of cervical cancer was compared to find a better DWI technique in terms of image quality and clinical utility.
Images in a 56-year-old woman with biopsy-proven squamous cell carcinoma of the cervix. Diffusion-weighted MR images and ADC maps show a cervical mass with an irregular margin, restricted diffusion and disruption of the cervical stromal rim. Compared with ss-EPI DWI and rs-EPI DWI, rFOV DWI images show the lesion with a clear border and fewer artifacts, and clearly demonstrate the findings of parametrial invasion in the right side (arrow).
Comparison of qualitative analysis scores among the reduced FOV DWI, rs-EPI DWI and ss-EPI DWI
