Hypothesis
Can non-contrast abbreviated MRI protocols effectively detect colorectal liver metastases compared to gadoxetic acid-enhanced MRI?
Conclusion
The non-enhanced abbreviated MRI protocol is as effective as the gadoxetic acid-enhanced protocol in identifying colorectal liver metastasis.
Supporting Evidence
- The non-enhanced protocol showed equivalent efficacy and was more cost-effective.
- Both MRI protocols matched the standard MRI protocol’s performance.
- Non-enhanced MRI offers shorter scan times and eliminates the need for contrast agents.
Takeaway
This study found that a quick MRI without contrast can find liver cancer just as well as a more complicated one with contrast, making it cheaper and easier.
Methodology
Ninety-four patients were assessed using three MRI protocols to compare their effectiveness in detecting colorectal liver metastases.
Limitations
The study's retrospective design and limited cohort size may affect the generalizability of the findings.
Participant Demographics
70 males (74.5%) and 24 females (25.5%), mean age 58.6 years.
