The Introduction to Transcranial Doppler online course is designed to provide a comprehensive introduction and review of Transcranial Doppler ultrasound. This enduring material is designed to provide a comprehensive review of how to perform and/or interpret TCD and TCI examinations.
This program will explore neuro-anatomy, Doppler waveform characteristics (normal/abnormal), scan techniques, diagnostic criteria, protocols specific to TCD/TCI exams, and clinical applications for TCD/TCI which are taught in accordance with AIUM and IAC guidelines.
This course is presented in six (6) modules and includes recommended reading assignments, online video lectures, case presentations, and post-activity quizzes.
- Doppler Ultrasound and Color Fundamentals
- Introduction to Transcranial Doppler ultrasound
- Clinical Applications for TCD: Part I
- Clinical Applications for TCD: Part II
- Clinical Applications for TCD: Part III
- Clinical Applications for TCD: Part IV
