Question

question 7
what is the advantage of using imaging such as ct scans, mris, and pet scans in diagnosis?
a can determine the antibiotic sensitivity of the infectious agent
b may save the patient from an invasive procedure
c very inexpensive and requires no cultivation of the specimen
d amplifies the dna in the patient sample for better genetic analysis

Explanation:

CT scans, MRIs, and PET scans are non-invasive imaging techniques. They visualize internal structures without inserting instruments into the body, avoiding risks of infection or trauma associated with invasive procedures. Option A is incorrect because imaging does not test antibiotic sensitivity (done via lab cultures). Option C is wrong as these scans are costly. Option D describes genetic testing methods, not imaging.

Answer:

B. May save the patient from an invasive procedure
