[Imaging of normal, hyperplastic and inflammatory prostate gland]

Area of Science:

• Urologic imaging and anatomy
• Prostate gland zonal anatomy
• Diagnostic imaging modalities

Background:

• The prostate gland comprises three distinct glandular compartments: transition zone, central zone, and peripheral zone.
• This zonal anatomy is identifiable using endorectal sonography and Magnetic Resonance Imaging (MRI).
• MRI offers superior analysis of seminal vesicles and vas deferens compared to sonography.

Observation:

• Endorectal or external surface coils can be utilized with MRI for prostate imaging.
• Knowledge of the relationship between prostate structures and capsular weaknesses is vital.
• Imaging plays a key role in assessing cancer extraprostatic extension.

Findings:

• Sonography is instrumental in the diagnosis, pre-therapeutic evaluation, and follow-up of benign prostatic hyperplasia (BPH).
• MRI provides better visualization of the internal structures of seminal vesicles and vas deferens.
• The utility of imaging in inflammatory prostate disorders remains less defined.

Implications:

• Accurate identification of prostate zonal anatomy via imaging improves diagnostic capabilities.
• Understanding anatomical relationships aids in staging prostate cancer and assessing treatment efficacy.
• Further research may clarify the role of imaging in inflammatory prostate conditions.
