Cardiac PET helps assess revascularization benefits
By Wayne Forrest
CHICAGO - By performing myocardial perfusion imaging with cardiac FDG-PET before revascularization, clinicians can better assess the benefits of that procedure and predict near-term outcomes for patients with coronary artery disease and left ventricular dysfunction, according to a study presented on Sunday at RSNA 2018.

3D printing gives pediatric heart surgery a boost
By Abraham Kim
Researchers in the U.S. have created hundreds of individually tailored 3D-printed cardiac models to facilitate presurgical planning for pediatric heart disease. Using these models has helped lower operating times and reduce costs, according to a new article published in 3D Printing in Medicine.

Heart valve-tracking algorithm boosts viability of 4D MRI
By Abraham Kim
An automated heart valve-tracking algorithm halved the amount of time and variability involved in blood-flow quantification with 4D MRI, according to an article published online October 30 in Radiology. The improved efficiency may help convince clinicians that cardiac 4D MRI is useful for assessing valvular heart disease.
