This phenomenon is known as flow related enhancement. Blood entering the slice during the gradient echo pulse sequence is unsaturated and therefore provides high signal. Stationary tissues become partially saturated and appear dark. Blood can be saturated using saturation bands to prevent signal generation from blood flowing in to the slice from a particular direction. The 2D slices can then be aggregated and a 3D maximum intensity projection can be formed. ========================= SIGN UP TO MY MONTHLY EMAIL NEWSLETTER 👉 *Not sure if the question banks are for you?* If you’re here, you’re likely studying for a radiology physics exam. I’ve spent the last few months collating past papers from multiple different countries selecting the most commonly asked questions. You’ll be surprised how often questions repeat themselves! The types of questions asked in FRCR, RANZCR AIT, ARRT, FC Rad Diag (SA), ABR qualifying Core Physics and MICR part 1 are surprisingly similar and the key concepts remain the same throughout. I’ve taken the most high-yield questions and answered them in video format so that I can take you through why certain answers are correct and others are not. Happy studying, Michael #radiology #radres #FOAMrad #FOAMed
