RADIOLOGY EXAM PREP UPDATED
QUESTIONS AND ACCURATE ANSWERS
FULL STUDY MATERIAL
●● The 3 Main purposes of Radiology are:
Answer: 1) Detect disease/cancer, injury, or abnormalities
2) Monitor treatment response
3) Guide procedures (biopsy, surgery, interventions)
●● How It Works: X Ray
Answer: Sends Photon Beams that are absorbed.
●● What is Sees Best: X-Ray
Answer: 1) Bone Tissue Density
2) Chest (contains air-filled lungs)
●● Example Uses: X-Rays
Answer: Fractures - 50%
Chest (Flu) - 30%
Skeletal Survey /
Bone Lesions - 20%
, ●● How It Works: CT Scan (Computered Tomography)
Answer: Multiple X-rays taken from different angles. A computer
comines them into slices and turns them into cross-sectional images of
organs, bones, and vessells.
●● What It Sees Best: CT Scans
Answer: Bones,
Organs,
Blood Vessels
●● Example Uses: CT Scan
Answer: Abdomen / Chest Pathology - 40%
Trauma - 30%
Tumors - 20%
Neuro/Stroke - 10%
●● How It Works: MRI (Magnetic Resonance)
Answer: MRI uses a strong magnetic field to align hydrogen atoms in
the body. Radio waves disturb these atoms, and the machine reads their
signals. Multiple sequences produce 3D images of soft tissues like
brain;spine,ligaments, and tumors
