Final answer:
CT scan and MRI are invasive imaging procedures requiring surgical asepsis.
Step-by-step explanation:
Invasive imaging procedures that require surgical asepsis to maintain a sterile environment typically include:
c. MRI (Magnetic Resonance Imaging) and d. CT scan (Computed Tomography).
Both MRI and CT scans involve invasive procedures that might require surgical asepsis in certain cases. While these imaging techniques don't involve incisions or direct penetration of the skin, some procedures might require interventions such as biopsies, aspirations, or other invasive techniques where maintaining a sterile environment becomes crucial to prevent infections.
Fluoroscopy (a type of X-ray that captures moving images) and standard X-ray (b) procedures generally do not involve invasive techniques that require surgical asepsis. However, proper hygiene and infection control practices are always essential to prevent cross-contamination or infections during these imaging procedures.
