Coronary Computed Tomography Angiography: Patient-related factors determining image quality using a second-generation 320-slice CT scanner.

Purpose: To investigate the diagnostic confidence of Coronary Computed Tomography Angiography (CCTA) and the effect of patient-related factors on CCTA image quality using a second-generation 320-slice scanner.

Methods And Results: 200 consecutive patients (mean age 60±12years; 109 men) prospectively underwent CCTA. The mean body mass index (BMI) was 27.

Diagnostic performance of quantitative coronary computed tomography angiography and quantitative coronary angiography to predict hemodynamic significance of intermediate-grade stenoses.

Fractional flow reserve (FFR) during invasive coronary angiography has become an established tool for guiding treatment. However, only one-third of intermediate-grade coronary artery stenosis (ICAS) are hemodynamically significant and require coronary revascularization. Additionally, the severity of stenosis visually established by coronary computed tomography angiography (CCTA) does not reliably correlate with the functional severity.

A comparative study between proximal radial morphology and the floating radial head prosthesis.

A morphometric study of the proximal radius was performed with computed tomography scanning in 51 healthy adults. These dimensions were then compared with those of a commercially available floating radial head prosthesis. Results were expressed as mean values, SD, and minimum and maximum values.
