Diagnostic Imaging Technology
- MRI
- How it
works
- The MRI scanner captures the
energy and creates a picture of
the scanned tissues
- Hydrogen atoms naturally exist in the body.
Radio waves redirect the alignment of the
hydrogen atoms in the body and and analyze
the energy different tissues emit when the
hydrogen atoms return to their typical
alignment in the body
- The MRI scanner captures the
energy and creates a picture of
the scanned tissues
- What it
shows
- Organs, soft tissues, bone
- Organs, soft tissues, bone
- Uses
- Evaluate organs of the
body/abdomen, pelvic organs
(bladder, reproductive organs),
blood vessels, and lymph nodes
- Diagnose and
monitor
treatments
- Evaluate organs of the
body/abdomen, pelvic organs
(bladder, reproductive organs),
blood vessels, and lymph nodes
- MRI diagnosing breast
cancer
- How it
works
- X-Ray
- How it
works
- Creates pictures of the
inside of your body in
different shades of
black and white.
Different tissues
absorb different
amounts of radiation
leading to the varying
shades of gray shown
on an x-ray
- Dense areas of the body that don't allow much of the
x-rays to pass through appear white (bones) as opposed
to hollow or air filled places of the body that appear black
(lungs)
- Dense areas of the body that don't allow much of the
x-rays to pass through appear white (bones) as opposed
to hollow or air filled places of the body that appear black
(lungs)
- Creates pictures of the
inside of your body in
different shades of
black and white.
Different tissues
absorb different
amounts of radiation
leading to the varying
shades of gray shown
on an x-ray
- What it
shows
- Bones, joint spaces, the
heart, (size/shape),
changes in density, and
fluid collection
- Bones, joint spaces, the
heart, (size/shape),
changes in density, and
fluid collection
- Uses
- Checking for broken
bones
- Spotting
pneumonia
- Spotting pneumonia
- Monitoring the
progression of a
disease
- Checking for broken
bones
- Normal foot and hand
x-ray
- How it
works
- Bone Scan
- How it
works
- A radiotracer that contains a small
amount of radioactive material is
inserted into a vein
- The substance travels through the
blood to the bones and organs
- As the substance wears off it
leaves traces of radiation
- The radiation is detected by a camera that slowly scans the
body
- The camera takes pictures of how much the radiotracer collects in the
bones
- The camera takes pictures of how much the radiotracer collects in the
bones
- The radiation is detected by a camera that slowly scans the
body
- As the substance wears off it
leaves traces of radiation
- The substance travels through the
blood to the bones and organs
- A radiotracer that contains a small
amount of radioactive material is
inserted into a vein
- What it
shows
- The various bones of the
skeleton
- The various bones of the
skeleton
- Uses
- Find bone cancer or determine if another
cancer has spread to the bone
- Diagnose the cause/location of unexplained bone
pain
- Diagnose broken bones not clearly seen on an
x-ray
- Find damage to
bones
- Find bone cancer or determine if another
cancer has spread to the bone
- Bone Scan showing a stress fracture on the right
leg
- How it
works
- CT Scam
- How it
works
- Combines many x-ray images with the
aid of a computer to generate images
that overlap to show all sections of the
body
- A large donut like machine
takes x-ray images at
many different angles
around the body
- A large donut like machine
takes x-ray images at
many different angles
around the body
- Combines many x-ray images with the
aid of a computer to generate images
that overlap to show all sections of the
body
- What it
shows
- Internal organs and
structures
- Internal organs and
structures
- Uses
- Define normal or
abnormal structure in
the bosy
- Assist in procedures by guiding
the placement of instruments
and treatments
- Define normal or
abnormal structure in
the bosy
- Bacterial pneumonia diagnosed through the abnormal obstruction of
the lung
