3D CT detection of perfusion defects mirrors SPECT

By Eric Barnes

VIENNA - Three-dimensional images from normal coronary CT angiography scans are highly sensitive for detecting fixed perfusion defects compared to myocardial SPECT. A special reconstruction technique performed with customized software does the job without the need for additional radiation or contrast.

320-slice coronary CTA permits much lower contrast dose

By Eric Barnes

VIENNA - Single-beat scanning not only enables significant radiation dose reductions in coronary CT angiography (CTA), the short duration of the scan permits drastically lower contrast doses as well, at least in patients with regular heartbeats and no arrhythmias.

MRI, MDCT err in estimating cardiac functional parameters

By Eric Barnes

MRI and MDCT assessments of left ventricular functional parameters were inaccurate when evaluated on a moving heart phantom with known parameters, according to a study in European Radiology. CT, particularly dual-source CT, did outperform MRI, however.

MRI detects bleeding in the heart after a heart attack

By Wayne Forrest

British researchers are using MRI to image hemorrhaging inside the heart to determine how much damage has been caused by a heart attack. Results of the study from the Medical Research Council Clinical Sciences Centre were published online in the journal Radiology.

Multislice CT can help guide surgery for infective endocarditis

By Reuters Health

NEW YORK (Reuters Health), Feb 13 - In patients with infective endocarditis, the accuracy of multislice CT for detecting valvular abnormalities is close to that of transesophageal echocardiography, and the newer technique could help in surgical planning, according to a report in the February 3 Journal of the American College of Cardiology.

320-detector-row CT cuts dose in triple rule-out exams

By Eric Barnes

Image quality is high and radiation dose is low when the so-called triple rule-out protocol is used with 320-detector-row CT to scan patients with chest pain, according to researchers from Berlin.

JAMA study finds wide variation in cardiac CTA dose

By Eric Barnes

Coronary CT angiography (CTA) providers are failing to protect their patients from high radiation dose -- with dose levels varying widely between facilities, according to a new multinational study in the Journal of the American Medical Association.

Thrombectomy a useful adjunct to primary PCI in STEMI: study

By Reuters Health

NEW YORK (Reuters Health), Jan 21 - Manual thrombus aspiration during primary percutaneous coronary intervention (PCI) improves myocardial reperfusion and reduces final infarct size in patients with ST-segment elevation myocardial infarction (STEMI), results of a European study indicate.

Flow reserve testing may improve PCI outcomes

By Reuters Health

NEW YORK (Reuters Health), Jan 15 - Adding fractional flow reserve measurements to angiography may improve survival and other outcomes for patients with multivessel coronary artery disease who undergo percutaneous coronary intervention (PCI) with drug-eluting stents, new research indicates.

MRI beats PET for myocardial evaluation in patients with impaired LV function

By Eric Barnes

While MRI is known to detect more myocardial scarring than PET in patients with occlusive coronary artery disease, a new study suggests that contrast-enhanced MRI can make a critical difference in treatment planning for revascularization candidates with severely impaired left ventricular (LV) function.
