MR – Cervical Spine T1-weighted ImageT2-weighted Image TR: 548 TE: 27 TR: 2581 TE: 104 CSF (water)

T1-weighted MR of the ankle 1) This tissue is dark (black) on all sequences 2) This tissue is bright on T1 and dark on STIR sequences 3) This tissue is dark gray on all sequences Match up numbers to letters: A)Fat B)Tendon C)Muscle Answers: 1) B; 2) A; 3) C

PET/CT Fusion 1) What radiotracer was used? 2) What does the red spot indicate? Answers: 1) Fluorodeoxyglucose (FDG); 2) Increased uptake, increased metabolic rate

MR vs. CT MRCT Note the bone (especially the cortex) is very white on the CT. Which is which?

Image Planes What imaging plane is this? Hint: This is the Atlas. Hint: It divides you into top and bottom? Answer: Axial plane; CT Bonus: What type of imaging is this?

Scintigraphy (Bone Scan) 1) What radiotracer was used here to track bone metabolism? 2) What kind of photon is being detected? Answers: 1) Technitium-99; 2) Gamma ray
