Hypothesis
Can optimized MRI sequences improve cardiac imaging in patients with implantable devices during radioablation treatment?
Conclusion
Optimized MRI sequences can effectively estimate heart motion in patients with cardiac devices, despite some imaging challenges.
Supporting Evidence
- The T1-GRE sequence was more robust against artifacts from cardiac devices compared to the bSSFP sequence.
- 85% of the left ventricle quadrants were successfully monitored using the bSSFP sequence.
- The study demonstrated the feasibility of real-time cardiac motion estimation despite the presence of CIEDs.
Takeaway
This study shows that special MRI techniques can help doctors see the heart better during treatment, even if patients have devices like pacemakers.
Methodology
Two MRI sequences were tested on healthy volunteers and a patient to assess their effectiveness in visualizing heart motion.
Potential Biases
Potential bias in manual landmark annotations and limited diversity in participant demographics.
Limitations
The study had a small sample size and focused on specific imaging sequences, which may not generalize to all patients with cardiac devices.
Participant Demographics
5 healthy volunteers (3 male, 2 female, mean age 27) and 1 male VT patient (83 years old).
