Diagnostic Imaging Questions
Which of the following is a common screening test for prostate cancer?
-
Prostate-specific antigen (PSA) test
-
Digital rectal exam (DRE)
-
Transrectal ultrasound (TRUS)
-
All of the above
D
Correct answer
Explanation
Prostate cancer screening typically involves a combination of tests, including the prostate-specific antigen (PSA) test, digital rectal exam (DRE), and transrectal ultrasound (TRUS), to assess the prostate gland and identify any abnormalities.
Which of the following is NOT a common screening test for colorectal cancer?
-
Colonoscopy
-
Sigmoidoscopy
-
Fecal occult blood test (FOBT)
-
Magnetic resonance imaging (MRI)
D
Correct answer
Explanation
Magnetic resonance imaging (MRI) is not typically used as a routine screening test for colorectal cancer, as it is more specialized and expensive compared to other screening methods.
Which of the following is NOT a common screening test for lung cancer?
-
Chest X-ray
-
Low-dose computed tomography (LDCT)
-
Sputum cytology
-
Magnetic resonance imaging (MRI)
D
Correct answer
Explanation
Magnetic resonance imaging (MRI) is not typically used as a routine screening test for lung cancer, as it is more specialized and expensive compared to other screening methods.
Which of the following is NOT a common screening test for osteoporosis?
-
Dual-energy X-ray absorptiometry (DXA) scan
-
Quantitative ultrasound (QUS) scan
-
Magnetic resonance imaging (MRI)
-
Bone density scan
C
Correct answer
Explanation
Magnetic resonance imaging (MRI) is not typically used as a routine screening test for osteoporosis, as it is more specialized and expensive compared to other screening methods.

Which medical imaging technique is commonly used to diagnose coronary artery disease?
-
Echocardiogram
-
Electrocardiogram (ECG)
-
Cardiac catheterization
-
Magnetic resonance imaging (MRI)
C
Correct answer
Explanation
Cardiac catheterization is an invasive procedure in which a thin tube is inserted into an artery or vein and guided to the heart. This allows doctors to visualize the coronary arteries and identify any blockages or narrowing.
