Question

question 9 of 10
for a patient concerned about radiation exposure, which imaging method
would a doctor most likely recommend for examining soft tissues?

a. digital x - ray

b. magnetic resonance imaging (mri)

c. computerized tomography (ct) scan

d. positron emission tomography (pet) scan

Explanation:

To determine the best imaging method for a patient concerned about radiation exposure and examining soft tissues:

• Option A (Digital X - ray): Uses ionizing radiation and is better for bone or dense structures, not ideal for soft tissues or low - radiation needs.
• Option B (MRI): Uses magnetic fields and radio waves, no ionizing radiation. It is excellent for visualizing soft tissues (like muscles, ligaments, organs).
• Option C (CT scan): Employs ionizing radiation, so it's not suitable for a patient worried about radiation exposure.
• Option D (PET scan): Involves radioactive tracers (ionizing radiation - related) and is more for metabolic studies, not primary for soft - tissue imaging with low - radiation priority.

Answer:

B. Magnetic resonance imaging (MRI)
