Ionizing radiation carries the risk of causing mutation in the developing fetus, and therefore is not used in imaging during pregnancy unless absolutely necessary. Which imaging modality does not use ionizing radiation?
Group of answer choices
O Fluoroscopy
O X-ray
O MRI
O CT



Answer :

Answer:

The correct answer is C. MRI

What is an MRI?

MRI is short for magnetic resonance imaging, which is a form of imaging inside the body without using radiation. Instead, it creates a magnetic field in the patient's body that forces the protons in the patient's body to align. Then, they send a radio wave through the patient's body. The protons get excited, and their energy can be read by the machine after the radio waves stop being sent out.

Fluoroscopies, X-rays, and CTs are all types of imaging that use radiation. X-rays are a single snapshot of the body, whereas CTs and fluoroscopies take many images to make a "movie" of sorts, so radiologists can look at a larger portion of the body, like for a screening for appendicitis that must be done quickly on a person who is most likely in a lot of pain and cannot sit still for very long.

C. MRI is the safest imaging modality during pregnancy as it does not use ionizing radiation, unlike X-rays, CT scans, and fluoroscopy.

Ionizing radiation can cause DNA mutations that are harmful to fetuses. Therefore, MRI is preferred for imaging when needed in pregnant women. Ionizing radiation is harmful to developing fetuses due to its ability to cause mutations in DNA. This type of radiation includes X-rays, CT scans, and fluoroscopy. However, MRI (Magnetic Resonance Imaging) does not use ionizing radiation, making it a safer option for imaging during pregnancy when necessary.
