3D T2-Weighted Imaging Could Shorten Prostate MRI Protocols
Apr 11, 2018
Three-dimensional acquisitions provide equivalent image and lesion delineation quality, compared to 2D in T2-weighted imaging of the prostate, according to a study published in the journal European Radiology.
Researchers from Austria performed a prospective study to determine if 3D acquisitions could provide equivalent image quality, lesion delineation quality and PI-RADS v2 performance compared to 2D acquisitions in T2-weighted imaging of the prostate at 3 T.
One hundred fifty patients (mean age 63.7 years; mean PSA 7.2 ng/ml) participated in the study. Two uroradiologists independently rated image quality and lesion delineation quality using a five-point ordinal scale and assigned a PI-RADS score for 2D and 3D T2-weighted image data sets. Data were compared using visual grading characteristics (VGC) and receiver operating characteristics (ROC)/area under the curve (AUC) analysis.
The results demonstrated equivalent image and delineation quality, and PI-RADS v2 performance, compared to 2D in T2-weighted imaging of the prostate.
