medical imaging final exam UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Purpose of bones scans - CORRECT ANSWER - -demonstrate physiological processes of
osteoblastic activity and regional blood flow to bone -provide an earlier diagnosis and
demonstrate more lesions than radiography
differnt kinds of bones - CORRECT ANSWER - 206 bones (short, flat, and irregular
bones)
2 sections of bones - CORRECT ANSWER - axial and appendicular
osteogenesis - CORRECT ANSWER - 1. production of the extravellular organic matrix 2.
mineralization of the matrix to form bone 3. bone remodeling by re-absorption and reformation
composition of bone - CORRECT ANSWER - ostocytes, osteoblasts, and osteoclasts
osteocytes - CORRECT ANSWER - mature bone cells
osteoblasts - CORRECT ANSWER - immature osteocytes that produce bone tissue that
replaces cartilage during ossification; works will osteoclasts to keep bones healthy and to keep
their shape
osteoclasts - CORRECT ANSWER - large cells that reabsorb/ digest bony tissue; work
with osteoblasts to keep bones healthy and to keep their shape
Bone imaging radiopharmaceuticals - CORRECT ANSWER - Tc99m MDP
, indications of skeletal imaging - CORRECT ANSWER - -evaluation of child abuse,

SPECT - CORRECT ANSWER - single photon emission computerized tomography;
camera rotates around a certain area of the patient and the patient stays in one spot
bone SPECT indications - CORRECT ANSWER - low back pain, spondylosis, or
spondylolisthesis
areas of uptake - CORRECT ANSWER - bone, kidneys, and bladder
