Dual-source CTA turns in mixed results for coronary stenoses

Dual-source CT angiography (CTA) achieves a high negative predictive value in excluding coronary artery stenoses in patients with stable coronary artery disease, but the modality is "very limited" in its ability to predict the presence of ischemia, according to a study by German researchers.

Adding PET to 64-slice CT aids detection of heart disease

Adding functional data from PET to 64-slice coronary CT angiography can improve the latter's ability to detect coronary artery disease, overcoming the modality's historic weak point in specificity, according to U.K. researchers.

Hybrid FDG-PET, MRI not ready for carotid plaque assessment

Although FDG-PET and MRI can contribute separately to the detection and assessment of carotid plaque, there is a lack of consensus between the two modalities when combined for hybrid imaging, according to U.K. researchers.

MRA recommended over CTA for following Kawasaki disease

Italian researchers recommend coronary MR angiography (MRA) as the modality of choice in the follow-up of patients with Kawasaki disease to reduce the potential cumulative effect of radiation exposure from repeat CT angiography (CTA) exams.

Greatest pain comes four hours after MR arthrogram injection

Researchers in Switzerland have found that patients who undergo MR arthrography temporarily experience the most pain in the affected joints four hours after injection. The study also showed that the pain is most pronounced in younger patients, but the discomfort for virtually all patients disappears after one week.
