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.

Volcano to buy OCT developer for $21.5M

Volcano, a developer and marketer of products for the diagnosis and treatment of coronary and peripheral artery disease, has entered into a definitive agreement to acquire Axsun Technologies, a privately held developer and manufacturer of lasers and optical engines used in optical coherence tomography (OCT) imaging systems.

Triple Rule-Out and Peripheral MRA

The so-called triple rule-outa single cardiac CT angiography (CTA) exam to evaluate for coronary artery disease, pulmonary embolism (PE) and aortic dissectionhas not had an easy road to mainstream acceptance. And for good reason. It tends to increase radiation exposure, compared to a coronary CTA study, and the majority of studies are negative for PE and dissection.

Cardiac CT triple rule-out passes several tests

Three studies have found that the triple rule-out exam is advantageous in certain patient populations and the senior author told Cardiovascular Business News that the postprocessing involved is simple and straightforward.
