MRI vs CT scans

Compare the relative effectiveness

both very detailed both expensive both can use a dye/contrast both can detect tumours/cancers both use giant machines, which a person is placed in both produce cross-section imaging both have patient lie on a narrow table

Contrast the relative effectiveness

MRI are more expensive than CT (about double the price of CT) MRIs take longer than CTs; can be up to 30 to 60 minutes, opposed to under 10 minutes. MRI are more detailed than CT MRI uses radio waves and magnetic waves while CT uses x-rays and digital computer technology. MRI take higher detailed images of soft tissue. CT take produce higher detailed images of bone structure. CT scans use ionising radiation The dye/contrast used in CT scans contain iodine; MRI does not. MRI can produce images of the body of the side or frontal; CT can only do horizontal

What are ethical principles?

are a guide or a standard of practice. standards of the professionals are used to guide research of the study of the brain.

Dye/contrast?

dyes (also known as contrasts) are sometimes used in MRI and CT scans. in some exams, a dye is required. the dye is given through a vein in the hand or arm, before the test begins. this is so the radiologist can see certain areas more clearly and appear more brightly. although, some people may experience nausea or even an allergic reaction.

What about radiologists?

radiologists have their own specific rules. . radiologists work within a professional code of conduct. some of these specific rules include: -consent -disclosure of risk -confidentiality -respect for persons -beneficence two of the most vital principles are disclosure of risks and consent. they must inform the patient of the dangers (disclose the risks) of having an MRI or CT scan.this is given to the patient in written form. most importantly, they MUST have the patients consent
