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.

Reducing Dose in Cardiac CT: Mature Methods are Making a Difference

Recently, medical professionals and CT system manufacturers have sought ways to reduce radiation exposure from coronary CT angiography (CCTA) exams. Today, it is possible to perform a CCTA study that delivers a lower radiation dose than the commonly used nuclear stress test. However, education and training are integral to establishing uniform coronary CCTA scanning standards and less dose to patients.

Advanced Visualization: Adding CCTA Post-Processing to the Physician Skill Set

Even with experienced technologists and user-friendly software, cardiologists who want to read coronary CT angiography (CCTA) exams still need to understand the basics of CCTA post-processing.

Users Hold Firm on the Value of Echo Contrast Agents

The FDAs warning on echo contrast agents galvanized physicians and sonographers to fight back. They enjoy a partial victory, but the fight is still on to prove safety and efficacy.

New Cardiac Biomarkers Target Plaque, Protein & Platelets

While well-established cardiovascular biomarkers still play a major role in clinical practice, many more biomarkers are vying for clinical attention.

Cardiac CT is Certifiable for Cardiologists & Radiologists

The American College of Radiology (ACR) has jumped into the cardiac CT certification business with its own exam: Cardiac CT Certificate of Advanced Proficiency (CCT CoAP). The first test will take place this September.Some third-party payors and hospitals already require cardiac CT imagers to demonstrate proficiency in the modality. The CCT CoAP will allow radiologists to provide that documented proficiency.In September 2008, the Certification Board of Cardiovascular Computed Tomography (CBCCT) offered its first exam. The organization later reported that the exam netted an 80 percent pass rate. The exam again will take place this September.

JAMA: Common ECG finding may indicate serious cardiac problems

A routine electrocardiogram (ECG) that signals a disorder of the electrical conducting system in one part of the heart previously believed to be benign is associated with an increased risk for atrial fibrillation, pacemaker implantation or death, according to a study in the June 24 issue of the Journal of the American Medical Association.
