Aquilion Prime SP 3 Phase VHP, CAP

Aquilion Prime SP

A 3 phase variable helical pitch (vHP) CT scan was performed in this male patient (HP 65-19-65). vHP combines gated and non-gated scan modes allowing contrast and radiation dose reduction. In this case the scan was non-gated/ gated/ non-gated. The patient's HR registered was 51 bpm. 3D Volume Rendered and Multiplanar Reconstruction (MPR) demonstrates no large vessel calcifications. No plaques or stenosis were found in the Right Coronary Artery (RCA) and in the Circumflex Coronary Artery (Cx). A myocardial bridge is seen in the Left Anterior Descending (LAD). *AAPM Report 96; k-factor 0.0145

Aquilion Prime SP SURESubtraction, Aortic Aneurism

Aquilion Prime SP

A SURESubtraction Abdominal Aortic CT scan was performed with AIDR 3D, Adaptive Iterative Dose Reduction. SURESubtraction scan improves the angiography workflow; the non-contrast and contrast scan are linked for faster set-up. During the reconstruction process, it automatically subtracts the bone, reconstruct types of images as requested and transfer the final images to the destination. 3D Volume Rendered, Maximum Intensity Projection (MIP), Curved Multiplanar Reconstruction (cMPR) and axial images demonstrate infrarenal aortic aneurysm with thrombus in lumen. *AAPM Report 96; k-factor 0.015

Aquilion Prime SP Lung CT, 1.3 mGy

Aquilion Prime SP

64-year-old male, a low dose scan of the chest was performed for lung nodule investigation. AIDR 3D, Adaptive Iterative Dose Reduction was automatically applied to the scan to improve image quality while lowering the radiation dose. Lung nodules are seen in the Multiplanar Reconstruction (MPR). *AAPM Report 96; k-factor 0.014

Aquilion Prime SP Pulmonary Embolism

Aquilion Prime SP

A female patient presented with chest pain and shortness of breath. An iodinated contrast enhanced Chest CT was performed with SUREkV and SUREExposure, automated kV and mA selection. Multiplanar Reconstruction (MPR) and curved MPR demonstrate bilateral pulmonary thrombo-embolism. Pulmonary consolidations are also seen bilaterally in the base of the lungs. *AAPM Report 96; k-factor 0.014

Aquilion Prime SP SEMAR, Prosthetic Joint Infection

Aquilion Prime SP

80-year-old female with bilateral joint arthroplasty presented with sudden fever and signs of hip inflammation. A CT scan of the abdomen was performed and automatically reconstructed with SEMAR, Single Energy Metal Artifact Reduction. The SEMAR images reveal an abscess, signal of prosthetic joint infection originally obscured due to the metal artifacts. *AAPM Report 96; k-factor 0.015
