In this AP x-ray view, x-rays travel from an anteriorly placed source to a posteriorly placed detector (x-ray beam passes from the front to the back of the body).
A radioactive (technetium-99m) phosphate compound is injected intravenously and bones are scanned for evidence of tumors.
Use of x-ray equipment and a computer to create multiple views of organs, including cross-sectional or axial images.
Material (contrast media) is injected into vessels and organs to obtain contrast with surrounding tissues when viewed on x-ray and other images.
Emission of glowing light that results from exposure to and absorption of radiation from x-rays.
Radioisotope (gallium 67) is injected intravenously and has an affinity for tumors and other lesions.
Machine to detect gamma rays given off by radiopharmaceuticals (radioactive compounds) during scanning for diagnostic purposes.
Time required for a radioactive substance to lose half its radioactivity by disintegration.
X-ray record of the endometrial cavity and fallopian tubes is obtained after injection of contrast material through the vagina and into the endocervical canal.
Saline solution is injected through a catheter inserted through the vagina and into the endocervical canal to distend the uterine cavity, which is then examined by ultrasound.
In vitro, In vivo
Process, test, or procedure performed, measured, or observed outside a living organism.
Combination of a radioactive substance (radionuclide) and a drug; used in nuclear medicine studies.
Magnetic resonance imaging
Magnetic field and radio waves produce sagittal, coronal, and axial images of the body; especially effective to image soft tissues.
X-ray image of the spinal cord after injection of contrast into the membranes surrounding the spinal cord.
Medical specialty that studies the uses of radioactive substances (radionuclides and radiopharmaceuticals) in the diagnosis of disease.
create a cross-sectional image of cellular metabolism in specialized areas of the body.
X-ray record of the kidneys (renal pelvis) and urinary tract after contrast is injected (intravenously or retrograde).
Medical specialty concerned with the use of x-rays for the diagnosis and treatment of disease.
Test combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient's blood.
Radioactive form of an element; gives off energy in the form of radiation; radioisotope.
Radioactive drug (radionuclide plus a drug) that is administered safely for diagnostic and therapeutic purposes.
Image of an area, organ, or tissue of the body obtained from ultrasound, radioactive tracer studies, or computed tomography.
Single photon emission
Radioactive tracer is injected intravenously, and a computer computed tomography reconstructs a three-dimensional image based on a (SPECT) composite of many views.
Thallium 201 is injected intravenously to allow for myocardial perfusion and assess damage to heart muscle from heart attacks.
Technetium Tc 99m
A nuclear medicine study in which a radiopharmaceutical sestamibi scan (Tc 99m sestamibi) is injected intravenously and traced to heart muscle to observe heart function.
An iodine 131 radionuclide is administered intravenously, and an image of the size and shape of the thyroid gland is obtained by scanning.
Radionuclides are attached to chemicals, used as tags or markers, and followed as they travel through the body.
Diagnostic technique that projects and retrieves high-frequency sound waves as they bounce (echo) off parts of the body.
