MR results in ankle disorders shore up surgical confidence, management

By Shalmali Pal

MRI can have a positive impact on the management of patients with ankle disorders, according to U.K. researchers. The group performed a prospective observational study in 91 consecutive patients, and also assessed MRI's impact on the orthopedic specialist's diagnosis as well as diagnostic certainty.

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.

PET/CT moves to prime time as first-line tool for lung cancer diagnosis

By Jonathan S. Batchelor

VIENNA - A study unveiled by researchers from Spain at this week's European Congress of Radiology (ECR) suggests that the current imbroglio swirling around CT screening may be only Sturm und Drang, at least when compared to the use of integrated PET/CT for lung cancer diagnosis. PET/CT has several advantages over PET and CT for diagnosing lung cancer, according to the group.

Italung-CT results show efficacy of lung cancer screening

By Eric Barnes

VIENNA - The first results of a sizeable Italian multicenter screening trial suggest once again that CT screening of smokers is effective in finding lung cancer in time to cure it. Presented at the European Congress of Radiology (ECR), the results are among the first of several randomized trials undertaken to assess the efficacy of CT lung cancer screening.

Scottish study shows potential gadolinium-NSF link

By Jonathan S. Batchelor

VIENNA - A clutch of recently published research studies has demonstrated the possibility of a link between the administration of gadolinium-based contrast agents and the development of nephrogenic systemic fibrosis (NSF) in patients with renal insufficiency. The link was further explored in a presentation by Scottish researchers today at the European Congress of Radiology (ECR).

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.

Penn researchers utilize new lung MR techniques

By AuntMinnie.com staff writers

Researchers at the University of Pennsylvania School of Medicine in Philadelphia are working with two new techniques for lung imaging with MRI: the use of hyperpolarized helium (3He) for ventilation imaging in humans, and injected polarized carbon-13 (C-13) labeled molecules in animal models.

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.
