Adding PET to 64-slice CT aids detection of heart disease July 20, 2009 -- 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.
Prospectively gated coronary CTA nearly equals normal-dose scans July 17, 2009 -- Researchers in Italy report that low-dose prospectively gated coronary CT angiography (CTA) scans are nearly equivalent to retrospectively gated exams in diagnostic accuracy, while reducing radiation dose by up to 72%, according to an article published in the Journal of the American College of Cardiology.
Hybrid FDG-PET, MRI not ready for carotid plaque assessment July 16, 2009 -- 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.
More intense hyperthermia better treats cervical cancer patients July 15, 2009 -- When it comes to adding hyperthermia treatment to radiation therapy for advanced cervical cancer patients, hotter and longer treatment is better. That's the conclusion of a Dutch study that found that more intense hyperthermia treatments can extend overall survival.
SPECT may aid in diagnosing early Alzheimer's disease July 14, 2009 -- VIENNA - SPECT may be useful for the very early detection of Alzheimer's disease, according to research reported at the Alzheimer's Association's 2009 International Conference on Alzheimer's Disease.
One-third of breast cancers overdiagnosed, European study finds July 13, 2009 -- Nine years ago, researchers from the Nordic Cochrane Centre roiled the women's imaging community with a study challenging the usefulness of mammography screening. Their new study, which indicates that screening mammography programs contribute to overtreatment of cancers that are actually harmless, is likely to have the same effect.
Virtual colonoscopy preferred for surveillance follow-up July 10, 2009 -- Patients referred for polyp surveillance after virtual colonoscopy are more likely to opt for another VC exam at follow-up, Italian researchers report. But patients want their follow-up scans sooner rather than later.
MRA recommended over CTA for following Kawasaki disease July 6, 2009 -- 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.
