HST 2025-26 Medical Imaging Day6-9

Ultrasound images are called

Echoes

This X-ray of the heart diagnoses heart disease

echocardiogram

An ultrasound gathers information by

bouncing sound waves off of objects

Ultrasounds can produce

2D, 3D and 4d images

An ultrasound uses sound waves to show

Soft Tissue

Inflammation in the air passages is found in

Asthma

CT images is good to generate

incredibly detailed, three-dimensional images of the bones

Arthroscopy is superior to X-ray when diagnosing

Damaged cartilage or inflammation in a joint

Health professionals who assist during a biopsy with a CT running are

Exposed to radiation

Which travels faster? Sound or light?

Sound

Pulmonary means

Having to do with the lungs

A biopsy is

The removal of cells to test for disease

Skin cancer, loss of fingers, severe burns are risks of

overexposure to radiation

Suspicious cells are sent to be examined by a

Pathologist

MRIs

do not emit radiation and use magnetism

All metals must be removed for an MRI except

a titanium replacement hip

This imaging is very useful in ER as it produces a high-quality, three-dimensional images in a short amount of time.

CT

An MRI can last for

45min to 1 hour

An MRI can be

claustrophobic and cause anxiety as it is an enclosed space

A radiopharmaceutical isotope:

Delivers radiation to the body

Nuclear medicine

uses gamma rays

A PET scanner

shows the structure and function of an organ

A radiopharmaceutical isotope

Delivers radiation to the body

To continue to work as a nuclear medicine technologists, they need to need to continue

schooling and continued education

AN MRI produces very detailed images of

soft tissues like the brain

Radiology staff must stop working for some time if they are exposed to

the limit for radiation exposure
