1.5T, 3.0T MRI are equivalent for assessing myocardial infarction
By Eric Barnes
In a new study by researchers from the U.K., 1.5- and 3.0-tesla MRI showed strong agreement in both mass and transmural extent of myocardial hyperenhancement (HE) when using the same imaging sequence for patients with previous myocardial infarction.

Reconstruction kernel dramatically affects stent evaluation
By Eric Barnes
VIENNA - If the results of a phantom study are valid in patients, the choice of reconstruction kernel with 64-slice CT has a critical impact on coronary artery stent evaluations. And as Dr. Florian Wolf explained at today's cardiac imaging sessions at the European Congress of Radiology (ECR), the evaluation of stents for detecting restenosis is critical for patient outcomes.

Coronary CTA saves money in intermediate-risk individuals
By Eric Barnes
VIENNA - Studies continue to show the value of coronary CT angiography (CTA) in individuals at high risk of coronary artery disease, but its value in individuals at intermediate risk is unclear. Now researchers of a new study, presented at the European Congress of Radiology (ECR), report that CTA is not only warranted for individuals in the middle of the Framingham risk profile, but that it saves money compared to other diagnostic modalities.

Automated emission correction shows potential for cardiac PET/CT
By Jonathan S. Batchelor
The CT portion of a hybrid PET/CT scan is commonly, and successfully, used for attenuation correction in these studies. Because acquisition during these exams is not simultaneous for each modality, nor is temporal resolution equivalent, the potential for data misregistration exists. Researchers from Germany have developed a method of automated emission correction that shows promise for image registration between the technologies, especially for cardiac studies.

MRI traces multisystem Fabry's disease in the brain, heart, and beyond
By Shalmali Pal
Fabry's disease is an inherited, gender-linked disorder caused by a deficiency of alpha-galactosidase A in the tissues and fluids. Renal, cardiac, and cerebrovascular complications can predispose patients with Fabry's disease to an untimely death in comparison to the general population. In the brain and the heart, MRI can track Fabry's disease patterns, giving physicians important information for therapy control.

MDCT offers cost-effective, reliable diagnosis in low-risk angina patients
By Eric Barnes
As many as 6 million patients with chest pain are admitted to emergency departments every year in the U.S. Coronary CT angiography (CTA), despite real limitations, has been shown to diagnose some patients quickly and accurately. In a new study, 64-slice CTA provided the correct diagnosis in 95% of patients with low-risk acute chest pain, leading the authors to conclude that CTA was well suited to diagnosing this population. Still, a quarter of the patients needed additional examination to determine that CT had been correct all along.

Calcium scoring requires individualized reconstruction phases
By Eric Barnes
Preset reconstruction phases won't cut it for retrospectively gated CT calcium scoring -- not if you want accuracy and reproducibility. A preliminary but ongoing study from the Netherlands has found that large errors can be introduced by the use of predetermined reconstruction intervals, particularly when hearts beat fast.
