Hybrid Imaging Virtual Workshop (02 25)-CAC Scores

Video Transcription

Video Summary

In this video, Dr. Andrew Einstein explains how to perform and interpret coronary artery calcium scores using quantitative and visual methods. He discusses the history of CT scanners and their development, including the invention of the CT scanner in 1967 and the first production CT machine, known as the EMI scanner, in 1972. He explains how electron beam CT scanners were developed in the late 1970s and early 1980s and were used to image the coronary arteries. Dr. Einstein also discusses the development of coronary artery calcium scoring by Dr. Arthur Agatston and Dr. Warren Janowitz. He explains how to perform and interpret a calcium score, including measurement parameters and thresholds for identifying calcified lesions in the coronary arteries. He also demonstrates how to visually estimate a calcium score from CT attenuation correction scans or image registration scans. Dr. Einstein emphasizes that calcium scoring can provide valuable information about a patient's risk of coronary artery disease and should be considered in addition to other imaging studies.
