Lesson 9.2 - PET Cases (Multimodality Approach)

Video Transcription

Video Summary

Dr. Krishna Patel discusses a case highlighting the role of PET in evaluating coronary artery disease in a 73-year-old woman with exertional chest pain. Initial tests, including a treadmill stress echo and coronary CT angiogram, showed moderate to severe lesions but were inconclusive in detecting significant epicardial CAD. A rest-stress rubidium PET revealed reduced stress flow and flow reserve, indicating coronary microvascular dysfunction, despite having no significant obstructive CAD. The case underscores that traditional tests may not identify microvascular disease and highlights PET's role in assessing coronary circulation hemodynamics.
