Summary
A bi-parametric prostate MRI protocol with a recall system for contrast administration is effective. This approach saves time and costs, reduces waitlists, and maintains patient care quality.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Prostate cancer diagnosis relies on MRI.
- Bi-parametric MRI (bp-MRI) omits contrast agents.
- A recall system for contrast administration can optimize bp-MRI efficacy.
Purpose of the Study:
- To evaluate the effectiveness of a recall system for bi-parametric non-contrast prostate MRI (bp-MRI).
Main Methods:
- Implemented a bp-MRI protocol in July 2020.
- Used T2-weighted and diffusion-weighted imaging (DWI) per PI-RADS v2.1 guidelines.
- Recalled patients with equivocal PI-RADS 3 lesions or technical limitations for contrast administration.
Main Results:
- Only 5.7% of 909 bp-MRI scans required recall.
- Recall was primarily for PI-RADS 3 lesions (78.8%) or technical issues (21.2%).
- Contrast administration upgraded 63% of recalled cases to PI-RADS 4; 37% remained PI-RADS 3. Significant cost savings (€64,620) and scanner time (214 hours 15 minutes) were achieved, enabling 255 additional bp-MRI scans and reducing waitlists from 1 year to 2-3 weeks.
Conclusions:
- A bp-MRI protocol with a recall system is efficient and cost-effective.
- This system significantly reduces patient wait times and backlog.
- The protocol maintains high-quality patient care while optimizing resource utilization.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
