Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

TCT: Robot-assisted PCI reduces rad exposure, increases safety

WASHINGTON, D.C.Using a robotic system during PCI may significantly reduce operator radiation exposure, improve patient safety and reduce the amount of contrast media, said Giora Weisz, MD, during a presentation this week at the 2010 annual Transcatheter Cardiovascular Therapeutics (TCT) annual conference.

JACC: Fused 3D MRI technique helps with CRT, coronary angioplasty

A cardiac MRI technique that provides a spatially matched 3D fused volumetric image of myocardial scar and the coronary arteries can be helpful for patients undergoing cardiac resynchronization therapy (CRT) or coronary artery revascularization, according to a study in the September issue of the Journal of the American College of Cardiology: Cardiovascular Imaging.

AJR: Adverse cardiac events rare one year after negative CTA

Researchers who followed low- to moderate-risk chest pain patients for one year after a negative cardiac CT angiography (CTA) in the emergency department found no signs or symptoms of adverse cardiac events during follow-up surveys, according to a study published in the October edition of the American Journal of Roentgenology.

Radiology: Cardiac MR details response to triathlon training

Cardiac MRI revealed cardiac adaptations, including a balanced increase in left ventricular and right ventricular myocardial mass, wall thickness, ventricular dilation and diastolic function, among  elite triathletes, according to a study published in the October edition of Radiology.

St. Jude debuts cardiac mapping system in Japan

AHA statement: CCTA has triage niche in chest pain patients

With the advent of 64-slice CT, coronary CT angiography (CCTA) exams of low-risk patients presenting to the emergency department with chest pain are feasible given the nearly 100 percent negative predictive value of the test, according to a scientific statement from the American Heart Association (AHA) published in the Aug. 17 issue of Circulation.

Circ: Integrating 3D CE-CT into ablation mapping improves outcomes

Using select data from 3D contrast-enhanced (CE) CT imaging can better locate areas to be ablated in patients with ventricular tachycardia, compared with standard voltage mapping, according to a small study published online July 24 in Circulation: Arrhythmia and Electrophysiology.
