Correspondence on the Study of 3D-Presumed Circular Area Ratio in MRI Evaluation of Benign Prostatic Hyperplasia

1

The study includes 335 patients with pathologically confirmed benign prostatic hyperplasia (BPH) for diagnostic accuracy.
2

3D-presumed circular area ratio (3D-PCAR) evaluates prostate morphology in three anatomical planes, extending conventional 2D measurements.
3

Coronal and sagittal PCAR showed stronger correlations with the International Prostate Symptom Score (IPSS) than axial PCAR.
4

3D-PCAR provides incremental value beyond conventional volumetric parameters, as demonstrated by nested regression analysis.
5

Suggestions for improvement include examining technical differences, reporting field strength effects, and proposing a PCAR threshold for clinically significant BPH.
