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.
