Diffusion-weighted Endorectal MR Imaging at 3 T for Prostate Cancer: Tumor Detection and Assessment of Aggressiveness
Hebert Alberto Vargas,Oguz Akin,Tobias Franiel,Yousef Mazaheri,Junting Zheng,Chaya S. Moskowitz,Kazuma Udo,James A. Eastham,Hedvig Hricak +8 more
TL;DR: Combined DW and T2-weighted MR imaging had similar performance to T1-weighting MR imaging alone for tumor detection; however, DW MR imaging provided additional quantitative information that significantly correlated with prostate cancer aggressiveness.
Journal ArticleDOI
Prostate Cancer Aggressiveness: Assessment with Whole-Lesion Histogram Analysis of the Apparent Diffusion Coefficient
Olivio F. Donati,Yousef Mazaheri,Asim Afaq,Hebert Alberto Vargas,Junting Zheng,Chaya S. Moskowitz,Hedvig Hricak,Oguz Akin +7 more
TL;DR: 10th percentile ADC correlated with Gleason score better than did other ADC parameters, suggesting that 10th percentile ADC may prove to be optimal for differentiating low-grade from intermediate- or high-grade prostate cancer with diffusion-weighted MR imaging.
Journal ArticleDOI
Prostate Cancer: Identification with Combined Diffusion-weighted MR Imaging and 3D 1H MR Spectroscopic Imaging—Correlation with Pathologic Findings1
Yousef Mazaheri,Amita Shukla-Dave,Hedvig Hricak,Samson W. Fine,Jingbo Zhang,Gloria Inurrigarro,Chaya S. Moskowitz,Nicole Ishill,Victor E. Reuter,Karim Touijer,Kristen L. Zakian,Jason A. Koutcher +11 more
TL;DR: The combination of ADC and MET performs significantly better than MET for differentiating between benign and malignant ROIs in the PZ, and was also better than ADC alone (AUC = 0.81).
Journal ArticleDOI
Prostate Tumor Volume Measurement with Combined T2-weighted Imaging and Diffusion-weighted MR: Correlation with Pathologic Tumor Volume
Yousef Mazaheri,Hedvig Hricak,Samson W. Fine,Oguz Akin,Amita Shukla-Dave,Nicole Ishill,Chaya S. Moskowitz,Joanna E. Grater,Victor E. Reuter,Kristen L. Zakian,Karim Touijer,Jason A. Koutcher +11 more
TL;DR: Adding DW MR to T2-weighted imaging can significantly improve the accuracy of prostate PZ tumor volume measurement, as well as identify malignant voxels within the suspected tumor regions.
Journal ArticleDOI
Assessment of Biologic Aggressiveness of Prostate Cancer: Correlation of MR Signal Intensity with Gleason Grade after Radical Prostatectomy
TL;DR: Investigating whether the signal intensity of prostate cancer on T2-weighted magnetic resonance (MR) images correlates with the Gleason grade at whole-mount step-section pathologic evaluation after radical prostatectomy found higher Gleason grades were associated with lower tumor-muscle SI ratios on T8weighted MR images.
