Pulmonary Embolism Detection and Characterization Through Quantitative Iodine-Based Material Decomposition Images With Spectral Computed Tomography Imaging

Abstract

Spectral CT imaging generated both monochromatic CTPA images for morphologic analysis of PE and material decomposition images for quantitative depiction of pulmonary blood flow and perfusion defects. Quantification of iodine density may be used as a predictor in distinguishing the presence or absence of PE and the severity of PE.
