Runoff, Femoral Artery Occlusion
Aquilion PRIME
CT Runoff Angiography was performed on a 73-year-old-male. The scan was acquired with SUREExposure automatic mA modulation, and SUREkV, automatic kV selection integrated into the protocol and applied to the scan. AIDR 3D, Adaptive Iterative Dose Reduction was integrated into the protocol and automatically applied to the scan.
3D Volume Rendered, Multiplanar Reconstruction (MPR) and Maximum Intensity Projection (MIP) images demonstrate peripheral arterial disease with superficial left femoral artery occlusion. Blood flow is seen bilaterally in the extremities.

DE, Multiple Kidney Stones
Aquilion PRIME
This patient presented with renal colic, an abdominal CT scan was performed for kidney stone investigation. As several stones were identified in the right kidney, a non-contrast Dual Energy CT scan was performed with restricted scan range for stones evaluation. Analysis of the multiple stones was subsequently conducted using the DE Stone Analysis application. The images demonstrate the stones in the right kidney represented in different colors. The analysis results show they are all composed of calcium oxalate and the stones are all color-coded blue. The material composition color scale is displayed on the left side of the image.
