Cardiovascular

 

Thanks to advances in MRI-compatible cardiac device technology, pacemakers and implantable cardioverter defibrillators (ICDs) are no longer absolute contraindications for MRI exams. The devices remain relative contraindications for MRI, however, and their presence in MRI patients calls for radiologists and cardiologists to work closely together in order to both ensure patient safety and minimize legal risk.  

The connection between chronic emotional stress and subsequent cardiovascular disease has long been substantiated on mostly circumstantial evidence. Now it’s been empirically established with imaging: A new study has put pictures to the heretofore unseen brain mechanism behind the mind/body double trouble.  

Researchers have shown that machine learning of 3D patterns in cardiac MRI can improve accuracy when it comes to predicting survivability of—and potentially guiding care for—patients with high blood pressure in the lungs. 

The prospect of leveraging lung cancer CT image data to look for other diseases of the chest is an appealing one, especially in this age of prioritizing value over volume. Indeed, a sound case for wide adoption of the practice has been madeNot so fast, argue three cardiothoracic radiologists in an opinion piece published online Oct. 4 in JACR. 

Researchers in Japan have demonstrated a way to modify a coronary CT technique such that it significantly cuts the time patients have to hold their breath while being scanned both with and without contrast, according to a study published online July 14 in Academic Radiology.
