Summary
Computed tomography (CT) can identify prostatic zonal anatomy in 24% of patients without prostate disease. Older age and larger prostate size correlate with better visualization of the peripheral and central zones.
Area of Science:
- Radiology
- Urology
- Anatomy
Background:
- Prostatic zonal anatomy is crucial for understanding prostate diseases.
- Computed tomography (CT) is a widely used imaging modality.
Purpose of the Study:
- To determine the frequency of visualizing prostatic zonal anatomy on CT scans.
- To identify factors associated with successful visualization.
Main Methods:
- Retrospective review of CT scans from 71 patients without known prostate disease.
- Analysis of image attenuation and contrast enhancement patterns.
Main Results:
- Prostatic zonal anatomy was discernible in 24% of patients.
- Lower attenuation of the peripheral zone compared to the central gland was observed.
- Visualization was more frequent in older patients with larger prostate glands.
- Intravenous contrast administration was necessary for visualization.
Conclusions:
- CT can visualize prostatic zonal anatomy, particularly in older individuals with larger prostates.
- Differences in attenuation and contrast enhancement may relate to benign prostatic hyperplasia.
