Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by external detectors (gamma cameras
What machine is used for scintigraphy?
Gamma cameras and PET scanners are the 2 basic types of cameras used to image the radioactive decay from the radiotracersradiotracersA radioactive tracer, radiotracer, or radioactive label, is a chemical compound in which one or more atoms have been replaced by a radionuclide so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products https://en.wikipedia.org › wiki › Radioactive_tracerRadioactive tracer - Wikipedia utilized in bone scintigraphy.
What is the difference between scintigraphy and spect?
SPECT-CT was superior to planar scintigraphy (P = 0.006). It characterized 94% of equivocal lesion seen on planar scintigraphy and characterized 44% of metastatic/probably metastatic lesions seen on planar scintigraphy as benign. SPECT-CT was also superior to SPECT alone (P = 0.006).
What are scintigraphic studies?
Scintigraphy implies the imaging method used in the field of nuclear medicine. A radioactive substance is used in all scintigraphic imaging studies. A specific radioactive substance is administered for each tissue or organ that is imaged and it is allowed to distribute homogeneously in the body.
What is scintigraphy used for?
Skeletal scintigraphy is a special type of nuclear medicine procedure that uses small amounts of radioactive material to diagnose and assess the severity of a variety of bone diseases and conditions, including fractures, infection, and cancer.
What is the difference between SPECT and SPECT CT?
The SPECT scan uses nuclear medicine to give good images of metabolic abnormalities, whereas the CT scan may be able to help narrow down specifically where the problem is occurring, such as in the bone or nearby tissue.
What is the difference between SPECT and Planar?
Overall, SPECT imaging yielded a higher sensitivity (93% vs 82% for SPECT and planar imaging respectively, p < 0.05), especially in the inferior and anterior regions. SPECT was also more sensitive for the detection of a single-vessel disease (90% vs 74% for SPECT and planar imaging respectively, p < 0.01).
What is the difference between SPECT?
The main difference between SPECT and PET scans is the type of radiotracersradiotracersA radioactive tracer, radiotracer, or radioactive label, is a chemical compound in which one or more atoms have been replaced by a radionuclide so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products https://en.wikipedia.org › wiki › Radioactive_tracerRadioactive tracer - Wikipedia used. While SPECT scans measure gamma rays, the decay of the radiotracers used with PET scans produce small particles called positrons. A positron is a particle with roughly the same mass as an electron but oppositely charged.
How is a bone scan conducted?
You'll be asked to lie still on a table while an arm-like device supporting a tracer-sensitive camera passes back and forth over your body. The scan itself can take up to an hour. The procedure is painless. Your doctor might order a three-phase bone scan, which includes a series of images taken at different times.Oct 9, 2019
Which radionuclide is used in scintigraphy?
technetium-99m
What machine scans bones?
Nuclear medicine uses a special gamma camera and single-photon emission-computed tomography (SPECT) imaging techniques. The gamma camera records the energy emissions from the radiotracerradiotracerA radioactive tracer, radiotracer, or radioactive label, is a chemical compound in which one or more atoms have been replaced by a radionuclide so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products https://en.wikipedia.org › wiki › Radioactive_tracerRadioactive tracer - Wikipedia in your body and converts it into an image. The gamma camera itself does not emit any radiation.
