ARRS: Ungated CT calcium scores downgrade cardiac risk
By AuntMinnie.com staff writers
Ungated CT plus Agatston calcium scoring is sufficient to clarify an individual's cardiac risk, usually reclassifying them downward compared to guidelines that aren't based on imaging exams, researchers reported at the American Roentgen Ray Society (ARRS) meeting in Toronto.

Half of positive SPECT patients negative at CCTA
By Eric Barnes
Nearly half of all patients who test positive on SPECT myocardial perfusion imaging are found to be negative at coronary CT angiography (CCTA), calling into question the routine use of SPECT myocardial perfusion imaging, a test that has been a mainstay of the diagnostic workup of patients with a clinical suspicion of coronary artery disease.

Chest pain patients do well after ultralow-dose SPECT
By Wayne Forrest
Patients with chest pain who underwent SPECT myocardial perfusion imaging with an ultralow-radiation-dose gamma camera had no major cardiac events a year later. The research, published in the April issue of the Journal of Nuclear Medicine, indicates that MPI radiation dose can be slashed without adverse clinical impact.

ACC: CT angio equal to functional tests for heart disease
By AuntMinnie.com staff writers
A multicenter study in the U.S. and Canada of more than 10,000 patients found CT angiography to be equivalent to functional tests such as stress echocardiography and nuclear myocardial perfusion imaging in patients with symptoms of heart disease, according to results presented at this week's American College of Cardiology (ACC) meeting in San Diego.

ACC: PET/CT trumps SPECT for cardiac studies
By Brian Casey
Researchers from Utah found that PET/CT is far superior to SPECT for diagnosing myocardial ischemia, with higher sensitivity at a lower radiation dose, according to a paper presented on Sunday at the American College of Cardiology (ACC) meeting in San Diego. PET/CT in particular far outstripped SPECT in determining that patients were free of cardiac disease.

ACC: CCTA sharpens diagnosis, targets intervention
By Frances Rylands-Monk
More accurate diagnosis using coronary CT angiography (CCTA) in chest-pain patients will reduce the risk of heart attack and hone treatment, according to a new study from Scotland that was presented at this week's American College of Cardiology (ACC) annual meeting in San Diego. Researchers found that patients with suspected angina benefited from clearer results after undergoing CCTA.
