Final Exam Review (Qns & Ans)

2025



1. Which imaging modality is most effective for detecting soft
tissue abnormalities?
A. X-ray
B. MRI
C. CT scan

,2. What is the purpose of contrast agents in diagnostic imaging?
A. Enhance image resolution
B. Detect bone fractures
C. Increase radiation exposure
D. Reduce scanning time
ANS: A. Enhance image resolution
Rationale: Contrast agents improve visualization of specific
structures and highlight differences in tissue density.


3. Which laboratory test is used to evaluate kidney function?
A. Complete blood count (CBC)
B. Lipid profile
C. Serum creatinine
D. Liver function tests (LFT)
ANS: C. Serum creatinine
Rationale: Serum creatinine assesses renal filtration
efficiency, making it a key indicator of kidney function.


4. Which therapeutic technique uses high-frequency sound waves
to break up kidney stones?

, A. Cryotherapy
B. Lithotripsy
C. Laser therapy
D. Phototherapy
ANS: B. Lithotripsy
Rationale: Lithotripsy uses ultrasound waves to fragment
kidney stones, allowing them to pass naturally.
