Overview/Diagnostic Imaging Flashcards
Denser materials such a bone or metal show brighter versus air, fat and less dense materials would be shades of gray.
X-ray
X-rays detect
- Bone fracture
- Articular cartilage damage
- Identify joint space change
- Articular derangement
A method where a treatment or evaluation is performed and guided by X-ray imaging.
Fluoroscopy
Multiple X-ray scans performed to view organs, bones, soft tissue and blood vessels providing greater detail than traditional X-ray. The X-ray slices are taken in succession showing progression through the body. The degree of radiation exposure is higher than a regular X-ray.
CT-Scan
CT-Scan best for
visualizing organs (esp. chest, lungs) for trauma, cancer etc.
Similar to a CT Scan, multiple slices are produced showing progression through the body. The difference, instead of X-ray, magnetic and radiowaves are applied to obtain images.
MRI (Magnetic Resonance Imaging)
MRI best for
showing tendon, ligaments and spinal cord vs CT-Scan
Which test is taken in 3 planes? (sagittal, axial, frontal)
MRI
Allows for realtime viewing of tissue/structures by applying high frequency ultrasound waves to generate images.
Ultrasound or Sonography
