ReviewNavigating the Pulmonary Perfusion Map: Dual-Energy Computed Tomography in Acute Pulmonary Embolism.
Pulmonary embolism is the third most common acute cardiovascular disease. Dual-energy computed tomography perfusion imaging is a promising adjunct in the detection of acute PE providing simultaneous functional assessment of pulmonary perfusion alongside the high-resolution morphological information from computed tomography pulmonary angiography. We review the evidence to date and common causes of perfusion defects including artifacts, parenchymal, and vascular causes, and discuss its potential in furthering our understanding of physiology and pathophysiology in acute pulmonary embolism.

Assessing the Relationship Between American Heart Association Atherosclerotic Cardiovascular Disease Risk Score and Coronary Artery Imaging Findings.
The aim of this study was to characterize the relationship between computed tomography angiography imaging characteristics of coronary artery and atherosclerotic cardiovascular disease (ASCVD) score. ⋯ There is some concordance but not a perfect overlap between 10-year ASCVD risk scores and coronary artery imaging findings.
