Explanation:

• For Question 10: A CAT - scan (Computed Axial Tomography scan) is a noninvasive roentgenography technique. An angiogram involves injecting contrast media into blood vessels (invasive), a PET scan uses radioactive tracers but is not roentgenography in the traditional X - ray sense, and Gamma Knife Surgery is a treatment, not a diagnostic technique.
• For Question 11: Spritam was the first 3D - printed drug approved by the FDA. It is used for treating epilepsy.
• For Question 12: A pacemaker can generate electrical stimuli to the heart muscle with fixed and/or alternate impulses to regulate the heartbeat.

Answer:

• Question 10: C. CAT scan
• Question 11: B. Spritam
• Question 12: B. fixed and/or alternate impulses
