Principles of imaging Flashcards
PT’s should be able to recongize when diagnostic imaging is needed to complete a comprehensive exam (True/false)
true
PTs should be able to _ info from the radiologists written report into the PT treatment plan
integrate
PTs should be able to _ understand the image to obtain info that may not be on the written report but be useful to the PT
visually
PTs should be able to recognize when imaging is NOT needed (true/false)
true
PTs should be able to _ regarding imaging
communicate effectively

The newer term for radiology is described as
medical imaging
This term is defined as: encompasses the expanded scope of radiologic practice that includes the application of x-rays, radioactive isotopes, and ionizing radiations to prevention, diagnosis, and treatment of disease
diagnostic/medical imaging
What are 3 areas of radiologic practice?
interventional radiology (treatment) radiation oncology (treatment) diagnostic imaging (prevention and diagnose pathology)
This term is defined as a subspecialty of radiology concerned with the diagnostic evaluation of the musculoskeletal system
musculoskeletal imaging

a. conventional radiography
b. advanced imaging
c. contrast radiography
d. none of the above
advanced imaging
This is described as a moving x-ray or a video image using x-ray
a. radiograph
b. fluoroscopy
c. contrast radiographs/studies
fluoroscopy
The process of obtaining an image using x-rays from a radiological modality is described as
conventional radiography
An x-ray film containing an image of an anatomic part of the patient requires what 3 things?
x-ray beam/source
patient
x-ray film/receptor
an x-ray represents different _ of the tissue
densities
Results of plain film radiography can be _ for clinical dx thus _ tx _ for clinical dx thus _ tx _ for one dx but _ of another _ thus need additional studies _
positive - direct negative - direct negative - suspicious inconclusive wrong
x-rays travel straight (true/false)
false
x-ray beams travel through various _ of the patient which _ varying amounts of radiation depending on the _
tissues
absorb
densities
The physical qualities of an object that determine how much radiation it absorbs from an x-ray beam/tube describes
a. radiodensity
b. composition
c. thickness
d. radiopaque
radiodensity
