Now we will review contrast enhanced magnetic resonance angiography. Gadolinium is used as the basis for most contrast agents in MRI. The seven unpaired electrons within the 4f orbital have non-zero spin values and therefore have a magnetic moment when placed in an external magnetic field. As a result gadolinium is paramagnetic. In high concentrations gadolinium drastically shortens the T1 time constant by increasing spin lattice interactions. This means the longitudinal magnetisation is recovered rapidly. In pulse sequences with short TR and TE values and larger flip angles, tissues without gadolinium will become saturated. Tissues with gadolinium will recover much of their longitudinal magnetisation prior to the next RF pulse (TR) and therefore, retain a larger transverse magnetistion vector. This is the basis for the bright signal in blood vessels in CE MRA. ========================= SIGN UP TO MY MONTHLY EMAIL NEWSLETTER 👉 https://bit.ly/3ruLh3d *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 QRnMgEnvI7Q |
