Diagnositic imaging

Radiography: Purpose? Identify and screen for lung & lung disease, fractures, dislocations, bone growth, foreign objects.
Radiography: Description? 2D image of a 3D object; at least 2 views are required to not neglect an abnormality
Radiography: ABCs? Use ABCs to interpret a musculoskeletal radiograph Alignment: size, contour, alignment with adjacent bone, Bone density: density & texture Cartilage spaces: joint space width, presence of sub-chondral bone, epiphyseal plates
Radiography: Advantages? Quick, easy. portable, relatively inexpensive
Radiography: Disadvantages? Ionizing radiation, poor at visualizing soft tissues and small fractures
MRI: Purpose? Provides sectional imaging of anatomy that is especially helpful for visualizing soft tissue. Also, can be configured into 3D models
MRI: Description? T1: fat is brighter & helpful in defining anatomy T2: fluid is brighter, fat is suppressed; helpful for various joint pathologies.
Functional MRI? Used to detect metabolic changes in the brain
MRI: Advantages? High quality imaging of almost any structure in the body; contrast can be used to increase detail
MRI: Disadvantages? Expensive, time consuming, pt must lie perfectly still to avoid artifacts, may not be able to distinguish between edema & tumors, may cause metal implants to malfunction
CT Scan: Purpose? Sectional imaging of bone and most soft tissues; especially good for chest and abdomen; also able to measure bone density
CT Scan: Description? Special radiography with computer analysis that configures images from x-rays at various angles to show high quality cross sectional and 3D imaging of body tissues and organs.
CT Scan: Advantages? fast and provides high quality imaging of bone, soft tissue, blood vessels all at the same time. Contrast can be use to increase detail
CT Scan: Disadvantages? Large amounts of ionizing radiation. Not as good as MRI at viewing soft tissue. Bariatric limits.
Bone scan: Purpose? Helps to diagnose fractures not detected by x-ray and areas of damage to bone caused by cancer, trauma, infection, etc.
Bone scan: Description? uses gamma ray emission to detect newly forming bone. Radionucleotide used--> increased area of uptake mean metabolic activity.
Bone scan: Advantages? Small amounts of radiation, improved detection of abnormal bone metabolism
Bone scan: Disadvantages? slow, ionizing radiation, potential adverse affects from radionucleotide
Angiography: Purpose? Views blood vessels
Angiography: Description? catheter and contrast material used in conjunction with x-rays, CT or MRI to examine blood vessels
Bone density exam: Purpose? Measure bone mineral density. Used to delineate osteopenia from osteoporosis
Bone density exam: Description? Enhanced x-ray technique. Gold standard for measuring bone density
Ultrasound: Purpose? Helps diagnose partial tendon tears, soft tissue masses, pockets of fluid, muscle development of activation
Ultrasound: Description? sound capture real time images of various body structures and blood flowing through the vessel
Positron emission tomography: purpose? Use to detect non perfusing areas of the heart to evaluate brain in cases of undetermined dementia, stroke, seizures, memory disorders or suspected tumors
PET: Description? POsitrons emitting from radioactive substances are captured
