What is the primary application of PET scans in the field of medicine?
Detecting fractures of various bones
Determine if a patient has diabetes
Determining bone mineral density
Visualizing and measuring metabolic processes in tissues
Which of the following imaging techniques is often combined with PET to provide both structural and functional information in a single scan?
X-ray radiograph
CT (computed tomography) scan
MRI (Magnetic Resonance Imaging)
Diagnostic ultrasound
What is the primary purpose of a DEXA scan?
To assess lung function
To evaluate metabolic activity in the bone
To measure bone mineral density
To detect soft tissue tumors
How does DEXA technology work to measure bone density?
It uses sound waves to assess bone strength.
It uses magnetic fields to visualize bone structure.
It emits two different levels of X-ray beams to measure bone absorption.
It measures bone density by assessing electrical conductivity.
Which medical imaging technique is primarily used to assess bone mineral density?
DEXA scan
PET scane
Bone scan
All of the above
Which of the following is a disadvantage of DEXA scans?
It is very expensive to get a DEXA scan.
It takes a long time to perform a DEXA scan.
There is a high radiation exposure with DEXA scans.
There may be inconsistencies between different DEXA devices.
Which of the following is an advantage of bone scintigraphy?
It is good at getting an overall assessment of arthritic joint distibution
It is very cheap compared to an X-ray radiograph.
It does not require exposure to radioactive pharmaceuticals
It can be used with an MRI to get good anatomic details.
Which of the following imaging modalities is the safest to do while a patient is pregnant?
PET scan
CT scan
Diagnostic ultrasound
Bone scan
