MR imaging of benign prostatic hypertrophy using a Helmholtz-type surface coil
Magnetic Resonance Imaging
|January 11, 1992
Summary
Magnetic resonance (MR) imaging reveals distinct patterns in benign prostatic hypertrophy (BPH). High-resolution MR with a Helmholtz coil enhances visualization of the prostate and surrounding structures.
Area of Science:
- Radiology
- Medical Imaging
Background:
- Benign prostatic hypertrophy (BPH) is a common condition affecting aging men.
- Accurate imaging is crucial for diagnosis and management of BPH.
Purpose of the Study:
- To characterize the MR imaging appearance of BPH.
- To evaluate the utility of a Helmholtz-type surface coil for prostate imaging.
Main Methods:
- MR examinations were performed on 18 patients with symptomatic BPH and 6 healthy volunteers at 1.5 T.
- A Helmholtz-type surface coil and a standard body coil were used.
- Morphologic features and signal intensity characteristics were analyzed.
Main Results:
- Recognizable MR patterns of BPH were identified, including nodular and diffuse heterogeneity.
- The peripheral zone showed moderate to high signal intensity in 78% of patients.
- Images acquired with the Helmholtz coil demonstrated significantly greater signal-to-noise ratios compared to the body coil.
Conclusions:
- The hyperplastic prostate gland exhibits diverse MR appearances with identifiable patterns.
- High-resolution MR imaging using a Helmholtz-type surface coil offers excellent anatomical detail of the prostate and adjacent structures.
