Medical Imaging Techniques

Question 1

what are the different MIT

Answer 1

Xray - Ct Scan - CAT scan - angiography
Positron Emission Tomography (PET)
Sonography / ultrasound
Magnetic resonance imaging (MRI)

Question 2

X-ray Imaging

Answer 2

uses xrays that penetrate soft organs and absorb denser organs
ex. bones, some tumors, tuberculosis nodules

Question 3

Computed Tomography CT / Computed Axial Tomography CAT

Answer 3

takes X-ray images of person’s axis to produce transverse body images and can view soft tissues as well as bone

Question 4

Angiography

Answer 4

images of blood vessels by having a contrast injected into blood vessel

Question 5

Positron Emission Tomography (PET)

Answer 5

detects radioactive isotopes injected into the body showing areas w/ increased cellular activity

ex. tumor growth or areas of the brain

Question 6

Sonography/ Ultrasound Imaging

Answer 6

uses high frequency sound waves that reflect body tissue to produce and image, safer for fetal imaging

Question 7

Magnetic Resonance Imaging (MRI)

Answer 7

detects levels of hydrogen in body (mostly water) by using magnetic fields, and shows soft tissue clearer
