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.

Myocardial bridging could serve as independent risk factor for arteriosclerosis

The segment proximal to a myocardial bridge, which is frequently involved in atherosclerotic plaque formation, could serve as an independent and significant factor with a higher odds ratio than other major risk factors for arteriosclerosis, according to a study presented last week at the 94th annual meeting of the Radiological Society of North America (RSNA).

Toshiba launches trial to compare 320-detector row CT to SPECT

Toshiba Medical Systems will support CorE 320, an international multi-center trial, beginning this month, to compare the effectiveness of 320-detector row dynamic volume CT to SPECT technology in identifying coronary stenosis.

Is Coronary CTA Really the Bad Boy of Cardiology?

It seems that CT imaging gets a lot of negative press around this time of year. In November 2007, the New England Journal of Medicine published an article by Brenner and Hall that said CT scans could be responsible for as much as 2 percent of all cancers in the United States in the next 20 to 30 years due the radiation exposure.

Stress CT perfusion imaging compares well to MRI to detect ischemia

CHICAGOAdenosine stress multidetector CT (MDCT) myocardial perfusion imaging can be successfully performed in patients with coronary artery disease (CAD), proving to have good agreement with stress myocardial perfusion MRI, according to research presented at the 94th annual meeting of the Radiological Society of North America (RSNA).
