3.1.1\ Scanning Method

The patient lies in supine position with his bladder moderately filled. Longitudinal scannings of the prostate are obtained from the suprapubic symphysis at the lower abdomen.

3.1.2\ Section Structure

This is a sagittal aspect of the prostate. The transitional zone and the central zone surround the proximate portion of the prostatic urethra, while the peripheral zone constitutes the inferolateral and apical portion of the gland. The bladder neck, the urethral orifice, and the prostatic urethra can also be shown.

3.1.3\ Measuring Method and Normal

Length (maximal head to foot) and anteroposterior diameter (anterior midline to posterior prostate capsule) can be measured.

3.1.4\ The Clinical Application Value

The size, form, echogenicity, and prostate capsule are the items to be observed. Prostatic calculi may easily form in the central zone. As the peripheral zone is prone to carcinoma of the prostate, attention should be paid to whether there are nodules in the zone and bulges of the capsule or not.
