Workshop on the Treatment of Pulmonary Embolism-CT: Beyond Positive vs. Negative for Acute PE, Dr. Robert Liotta

CT: Beyond Positive vs. Negative for Acute PE, Dr. Robert Liotta

Video Transcription

Video Summary

The presentation discusses distinguishing acute from chronic pulmonary embolisms (PE) using imaging. Acute PE features include central filling defects and enlarged vessels due to high pressure. Indicators of chronic PE include right ventricular hypertrophy, collateral vessels, peripheral filling defects, intimal irregularities, and smaller obstructed vessels. Other signs include web-like filling defects, mosaic lung attenuation, and pulmonary infarcts. Right ventricular dysfunction is identified by comparing ventricle sizes and checking for wall hypertrophy. Dual energy CT scans help assess perfusion, supplementing traditional CT to detect potential PEs.
