Radiology And Nuclear Medicine Flashcards
Nuclear physician
MD- reads/orders scans
Radiologic technologists
Radiographers, nuclear medicine technologists, sonographers
Posteroanterior (PA) view
Posterior source to anterior detector
Anteroposterior (AP) view
Anterior source to posterior detector
Eversion
Turning outward
Extension
Lengthening or straightening a flexed limb
Flexion
Bending a part of the body
Lateral decubitus
Lying down on the side
Prone
Lying on the belly (face down)
Recumbent
Lying down (prone or supine)
Supine
Lying on the back (face up)
Radiopaque
Obstructing the passage of x-rays
Radionuclides/radioisotopes
Alpha/beta particles and gamma rays
Nuclear medicine tests
In vitro (test tube) In vivo (in the body)
Radioimmunoassay (RIA)
Radioactive chemicals/antibodies to detect hormones/drugs in patient blood (in vitro)
Radiopharmaceutical (concentrates in organ)
Radioactive substance drug used for diagnostic/therapeutic purposes
Scintiscanner (gamma camera) detection instrument produces picture (scintiscan)
Radioactive substance given to patient to evaluate organ function or image
DICOM
Digital imaging and communications in medicine; the international standard for medical images and related info. Defines formats/protocols for medical images that can be exchanged w/ data/ quality necessary for clinical use
Radiopharmaceutical
Radioactive drug used for diagnostic/therapeutic purposes
Scan
Image of area/organ/tissue of body obtained from ultrasound, CT, MRI, radioactive tracer studies
Scintigraphy
Diagnostic nuclear medicine test using radiopharmaceuticals and gamma cameras to create images
Radiologist
MD- reads x-rays determines radiation therapy dosing
Bone scan
Procedure uses radionuclides
Lymphoscintigraphy
Procedure uses radionuclides
Positron emission tomography (PET) scan
Procedure uses radionuclides
PET/CT scan
Procedure uses radionuclides
Single-photon emission 3D computed tomography (SPECT)
Procedure uses radionuclides
Technetium Tc-99m sestamibi (Cardiolite) scan
Procedure uses radionuclides
Thallium 201 (Tl) scan
Procedure uses radionuclides
Thyroid scan
Procedure uses radionuclides
Scintigraphy
Radionuclide scanning
PET
Positron emission tomography
How is a pet scan useful?
Treating stroke, epilepsy, Alzheimer’s, brain tumors, abdominal/pulmonary malignancies
What does a PET scan do?
Concentrate radioisotopes in tissues where the radionuclide is or is not being metabolized
What does a PET scan show?
Radioisotopes (emission of positrons) instead of contrast x-rays
