Episode notes
Whole Body MRI Reveals Deep Cardiovascular Risk Markers
- Whole body MRI can quantify cardiovascular risk markers beyond traditional scores.
- Measures like muscle size, intramuscular fat, visceral fat, and aortic/heart calcification may outperform Framingham in some studies.
Follow Evidence Based Guidelines Before Elective Imaging
- Follow evidence-based guidelines before pursuing novel imaging tests now.
- Without randomized trials, extra imaging may add uncertainty and harms from incidental findings despite promising future uses.
Use Coronary Calcium Scoring Only For Appropriate Patients
- Coronary artery calcium scoring is useful for specific patient populations who meet screening criteria.
- In appropriate patients it guides more aggressive blood pressure, cholesterol control and behavior change, but it's not for everyone due to radiation and incidental findings.
