Article Figures & Data

Figures

  • Figure 1.
    Figure 1.

    Bland-Alman plot of prostate volume (A) and prostate-specific antigen density (B).

  • Figure 2.
    Figure 2.

    ROC curve analysis.

  • Figure 3.
    Figure 3.

    Box-plot of prostate-specific antigen density obtained from the segmentation method (PSADs) and PSAD obtained from the ellipsoid volume formula (PSADe). (A) PSADs and PSADe of different risk groups [low/very-low risk (GS=6), intermediate risk (GS=7), and high/very-high risk (GS >7)] (p=0.023 and p=0.033). (B) PSADs and PSADe values in different tumor locations (p=0.472 and p=0.357).

  • Figure 4.
    Figure 4.

    T2-weighted axial image (A), coronal image (B), and sagittal image (C) of the prostate gland with a large hyperplastic nodule (N) at the prostate base, which is approaching the left seminal vesicle (S) and urinary bladder (U). The prostate volume was calculated by the “ROI volume” tool in Osirix (D). In this case, the prostate volume calculated by the segmentation method was 47.2 ml, and the prostate volume calculated by the ellipsoid volume formula was 33.6 ml.
