Certain MRI Findings May Predict Future Cardiac Events
Cardiac magnetic resonance imaging may help clinicians predict future cardiac events among patients with coronary artery disease or recent MI.
Some MR imaging findings, such as left ventricular ejection fraction (LVEF), may have prognostic value regarding future cardiac events, according to a study published in the Journal of the American College of Cardiology.
Researchers from the Netherlands undertook a meta-analysis to review the prognostic value of cardiac magnetic resonance (CMR) in for future cardiovascular events in patients with coronary artery disease (CAD) or a recent myocardial infarction (MI).
The researchers identified 56 studies with 25,497 patients. After review, the researchers found that too few patients with a recent MI had been evaluated to establish associations between CMR findings and hard events (all-cause mortality, cardiac death, cardiac transplantation, and MI). However, it was found that in this group, LVEF was independently associated with major adverse cardiac events (MACE).
For patients with suspected or known CAD, the studies showed that wall motion abnormalities, inducible perfusion defects, LVEF, and infarction were independently associated with hard events. As well, the presence of inducible perfusion defects was associated with MACE.
The authors concluded that these findings indicate the utility of developing reporting guidelines using CMR among patients with CAD or recent MI.
MRI or Ultrasound for Evaluating Pelvic Endometriosis?: Seven Takeaways from a New Literature Review
September 13th 2024While noting the strength of MRI for complete staging of disease and ultrasound’s ability to provide local disease characterization, the authors of a new literature review suggest the two modalities offer comparable results for diagnosing pelvic endometriosis.
Diffusion-Weighted MRI and Neoadjuvant Chemotherapy for Rectal Cancer: What New Research Reveals
September 3rd 2024In a comparison of imaging assessments to gauge the effectiveness of neoadjuvant chemotherapy for rectal adenocarcinoma, researchers found the combination of diffusion-weighted imaging and MR tumor regression grading had a 90 percent area under the curve (AUC) and a negative predictive value (NPV) of 93 percent.
