MR images of human prostate gland are lightly affected motion artifact from the patient's free-breathing. MR images are superior to Computed Tomography Images at contrast resolution in pelvic region. We measured prostate gland capacity from 20 volunteers (average age: 23.08 years old) who had no symptoms related to the prostate. We recalculated the MR imaging by the Chapman method. We created two cross-sectional images from prostate's MR images at the following; Coronal Oblique plane (follow the shape of the ejaculatory duct and distal urethra segment), Double Oblique plane (vertically-directed coronary plane from distal urethra segment), which is defined from zonal anatomy which proposed by McNeal JE. For 20 volunteers' studies, the average capacity of the prostate is 15.72 cc. The almost same volume was calculated from both Coronal Oblique plane and Double Oblique plane.
