Radiography
Visual: dense structures
Used: bones, lungs
Detects: fractures, tumors, lesions
47
Fluoroscopy
visual: deep tissues and hollow structures
used: intestine tract, heart, urinary tract, and reproductive systems
detects: reflux, obstruction, ulcers
48
Sonography
visual: soft tissue structures, blood movement, levels of dense with tissues
used: heart, blood, eyes, thyroid, brain, breast, organs, skin, and muscles
detects: cysts, tumors, gallstones, vessel blockages, prenatal abnormals
49
Magnetic resonance (MR)
visual: organs, spine, joints, vessels
used: brain, spine, joints, gallbladder and bile
detects: tumors, torn ligaments, gallstones
50
Computed tomography (CT)
visuals: organs, blood, tissue denseness
used: bones, heart, lungs, vessels, abdominal organs
detects: disease, injuries, fractures, clots, internal bleeding, tumors
51
Positron emission tomography (PET)
visuals: cell and tissue activity
used: brain, heart, vessels
detects: cancer, flow of blood to heart
52
Single photon emission computed tomography (SPECT)
visual: blood flow, cellular and tissue activity
used: heart, brain, bones
detects: infection, tumors, bloackages
53
nuclear medicine (NM)
imaging of internal structures by using a Gamma camera to detect radiation from different parts of the body after a radioactive material (radioisotope) has been given to the patient. Computer software assembles data into images called scans.
54
magnetic resonance imaging (MRI)
high strength, computer-controlled magnetic fields producing a series of sectional images (slices) that visualize abnormalities such as swelling, infections, tumors, and herniated disks
55
Scan
