Some DSCT chest scans permit coronary evaluation
By Eric Barnes
High-pitch chest imaging with dual-source CT (DSCT) is robust enough to image the coronary arteries in many patients -- despite fast heart rates and nongated CT acquisitions, according to a study conducted by a French group that included Dr. Martine Rémy-Jardin.

Take strict precautions when it comes to pacemakers and MRI
By Frances Rylands-Monk
The emergence of MRI-compatible pacemakers has revolutionized patient management, but this relatively new clinical combination of pacemaker with MR systems means that radiologists are often only partially aware of the associated risks.

PE defect size on CT correlated to poor clinical outcomes
By Eric Barnes
Perfusion defect size on dual-energy CT of pulmonary embolism (PE) is an independent predictor of both right heart strain and patient outcomes, concludes a new study by German and U.S. researchers. On the other hand, lab markers such as D-dimer results showed only weak correlations.

Good sensitivity seen in large French CTA trial
By Eric Barnes
The largest multicenter study ever undertaken in France to establish the clinical value of coronary CT angiography (CTA) in stable patients delivered good sensitivity for detecting coronary artery disease.

High-pitch DSCTA often repeated, but dose still lower
By Eric Barnes
VIENNA - Nearly one in five coronary CT angiography scans acquired with an emerging high-pitch dual-source CT angiography (DSCTA) protocol needs to be repeated. But the low-dose acquisitions possible mean even repeated scans have lower overall doses than comparable 64-detector-row CTA scans, researchers reported at the European Congress of Radiology.

CT limited for detection of subtle aortic tears
By Eric Barnes
VIENNA - Even with electrocardiographic gating, CT angiography cannot confidently visualize subtle aortic tears of the ascending aorta. Transesophageal echocardiography may be a better option in some patients, according to a presentation Thursday at the European Congress of Radiology.

320-row coronary CTA accurate in atrial fibrillation patients
By Eric Barnes
CT with a 320-detector-row scanner holds several advantages for CT angiography (CTA) of patients with atrial fibrillation and suspected coronary artery disease, concludes a study published online in European Radiology.

DECT for myocardial perfusion does more for less than SPECT
By Eric Barnes
A study published online February 1 in the European Journal of Radiology found that dual-energy (DE) coronary CT angiography (CTA) outperformed SPECT for assessing myocardial perfusion in patients with suspected coronary artery disease.

Most-severe coronary perforations still challenge cardiologists, high risks to patients
By Reuters Health
NEW YORK (Reuters Health) - Although rare, grade III coronary perforations remain associated with high rates of acute and long-term major adverse cardiac events, according to a recent study by Italian and English researchers.

3D MRI stress perfusion accurate for myocardium evaluation
By Eric Barnes
New research from Germany shows how cardiac MRI can assess myocardial function by combining cine imaging, stress perfusion, and scar imaging to produce a high percentage of correct diagnoses and high-quality images, according to results published January 25 in the Journal of the American College of Cardiology.

Radiation may increase long-term heart risks
By Reuters Health
NEW YORK (Reuters Health) - Women treated for breast cancer with radiation therapy are more likely to die from heart disease 20 years or more down the line than women who don't get radiation, according to a new study.
