A Jaszczak phantom (Polish pronunciation: [ˈjaʂ.t͡ʂak] ⓘ) aka Data Spectrum ECT phantom [1] is an imaging phantom used for validating scanner geometry, 3D contrast, uniformity, resolution, attenuation and scatter correction or alignment tasks in nuclear medicine.
The indium white blood cell scan is a nuclear medicine procedure in which white blood cells (mostly neutrophils) are removed from the patient, tagged with the radioisotope Indium-111, and then injected intravenously into the patient. The tagged leukocytes subsequently localize to areas of relatively new infection.
Gallium scan showing panda (A) and lambda (B) patterns, considered specific for sarcoidosis in the absence of histological confirmation. In the past, the gallium scan was the gold standard for lymphoma staging, until it was replaced by positron emission tomography (PET) using fludeoxyglucose (FDG).
Nuclear medicine tests differ from most other imaging modalities in that nuclear medicine scans primarily show the physiological function of the system being investigated as opposed to traditional anatomical imaging such as CT or MRI. Nuclear medicine imaging studies are generally more organ-, tissue- or disease-specific (e.g.: lungs scan ...
MIP Display was invented for use in Nuclear Medicine by Jerold Wallis, MD, in 1988 at Washington University in St. Louis, and subsequently published in IEEE Transactions on Medical Imaging. [2] In the setting of Nuclear Medicine, it was originally called MAP (Maximum Activity Projection). [3] [4]
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 gamma cameras, which are external detectors that form two-dimensional images [1] in a process similar to the ...
Gamma counters are used in radiobinding assays, [5] radioimmunoassays (RIA) [6] and nuclear medicine measurements such as GFR [7] and hematocrit. [ 8 ] Some gamma counters can be used for gamma spectroscopy to identify radioactive materials based on their output energy spectrum, e.g. as a wipe test counter .
