To compare overall number of downstream tests and total costs between negative exercise stress echocardiograms (ESE) or cardiac computed tomography angiography scans (CCTA) in symptomatic Tricare beneficiaries suspected of having coronary artery disease (CAD). [1] 1026 computed tomography angiography scans of adults were evaluated and the presence of left-sided (LAA) and right-sided (RAA) AA were determined in 1023 (99. [2] We estimated vascular calibers from fundus images and fractal dimension (FD) from optical coherence tomography angiography scans. [3] The number of FV was analyzed according to the size which from 6×6-mm swept source optical coherence tomography angiography scans. [4] 5 mm optical coherence tomography angiography scans were recruited. [5] Computerized Tomography Angiography scans from 211 subjects 5-93 years old (mean age 47±24 years, 127M/84F) were used to build 3D vascular reconstructions and measure arterial diameters, tortuosity, and calcification volumes in six vascular zones spanning from the ascending thoracic aorta to the pelvic arteries.
