Aquilion Prime SP RCA Stenosis

Aquilion Prime SP

76-year-old female, BMI of 28, presented with atypical chest pain. Cardiac CTA was performed with AIDR 3D, Adaptive Iterative Dose Reduction. The patient's heart rate was varying from 55 to 63 bpm. AIDR 3D was integrated into the scan protocol and images automatically reconstructed ensuring diagnostic image quality. Curved MPR and 3D Volume Rendered images demonstrate calcified plaques in the proximal and mid segments of the RCA (Right Coronary Artery), mixed plaque with significant stenosis in the mid-RCA. Calcifications are also visualized in the proximal LAD (Left Anterior Descending Coronary Artery). *AAPM Report 96, k-factor 0.014

Aquilion Prime SP Cardiac CTA

Aquilion Prime SP

40-year-old male presented atypical chest pain. A SURECardio Prospective CT Angiography was performed with AIDR 3D, Adaptive Iterative Dose Reduction integrated into the protocol and automatically applied to the scan. The patient's heart rate was 60 bpm during the scan. 3D Volume Rendered and curved Multiplanar Reconstruction (cMPR) demonstrate no significant coronary arteries disease. *AAPM Report 96, k-factor 0.014

Aquilion Prime SP Coronary Artery Disease

Aquilion Prime SP

64 year-old male with history of hypercholesterolemia and family history of myocardial ischemia. A Cardiac CTA was performed utilizing SURECardio prospective scan mode ensuring the best scan parameters are selected according to the patient's HR (heart rate). The patient's HR during scan was 52 bpm. Curved Multiplanar Reconstruction (cMPR), 3D Volume Rendered and axial images demonstrate diffuse coronary artery disease. *AAPM Report 96, k-factor 0.014
