Diffusion weighted imaging uses a series of MRI pulse sequences to generate both a b0 (b zero) image as well as many source diffusion weighted images. The signal from the source images is combined to form a DWI trace image. Here we discuss the process of creating these images and what the measured signal represents. We then look at how we can use the b0 and DWI trace images to create an ADC map. ========================= 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
