Myocardial perfusion in patients with suspected coronary artery disease: comparison between 320-MDCT and rubidium-82 PET.

Objectives: Despite advances in non-invasive myocardial perfusion imaging (MPI) evaluation, computed tomography (CT) multiphase MPI protocols have not yet been compared with the highly accurate rubidium-82 positron emission tomography (RbPET) MPI. Thus, this study aimed to evaluate agreement between RbPET and 320-detector row CT (320-CT) MPI using a multiphase protocol in suspected CAD patients.

Methods: Forty-four patients referred for MPI evaluation were prospectively enrolled and underwent dipyridamole stress RbPET and multiphase 320-CT MPI (five consecutive volumetric acquisitions during stress).

Use of imaging and clinical data to screen for cardiovascular disease in asymptomatic diabetics.

Background: There is increasing evidence to suggest that not all individuals with type 2 diabetes mellitus (T2DM) have equal risk for developing cardiovascular disease. We sought to compare the yield of testing for pre-clinical atherosclerosis with various approaches.

Methods: 98 asymptomatic individuals with T2DM without known coronary artery disease (CAD) were enrolled in a prospective study and underwent carotid ultrasound, exercise treadmill testing (ETT), coronary artery calcium (CAC) scoring, and coronary computed tomography angiography (CTA).
