Summary
Automatic software accurately detects prostatic arteries (PAs) using dual-phase cone-beam CT during prostatic artery embolization (PAE), aiding in precise identification and treatment.
Area of Science:
- Interventional Radiology
- Medical Imaging
- Vascular Anatomy
Background:
- Prostatic artery embolization (PAE) requires precise identification of prostatic arteries (PAs).
- Manual identification of PAs can be time-consuming and challenging during PAE procedures.
Observation:
- Dual-phase cone-beam CT (CBCT) imaging was utilized in conjunction with vessel-tracking software.
- The software automatically detected 92% of target prostatic arteries across six patients.
Findings:
- The automatic software demonstrated high sensitivity in detecting both right (100%) and left (83.3%) PAs.
- False-positive rates were manageable (14% right, 25% left) and corrected through review.
Implications:
- Automated PA detection via CBCT offers a potentially faster and more reliable method for identifying PAs during PAE.
- This technology could improve the efficiency and success rates of PAE procedures for benign prostatic hyperplasia.
