Nuclear medicine (nuclear radiology, nucleology), [1] [2] is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear imaging is, in a sense, radiology done inside out , because it records radiation emitted from within the body rather than radiation that is transmitted through ...
In flanged models, the sizes of the spheres vary. The number of rods in each set depends on the size of the rod in that set as different models of the phantom have rods of different sizes. In flangeless models, the diameters of the spheres are 9.5, 12.7, 15.9, 19.1, 25.4 and 31.8 mm, while the rod diameters are 4.8, 6.4, 7.9, 9.5, 11.1 and 12.7 mm.
It is sometimes used as a test for the diagnosis of acute pyelonephritis. [4] However, the sensitivity of DMSA scan for acute pyelonephritis may be as low as 46%. [5] Procedure: Patient is injected with 2-5 mCi of Technetium-99m DMSA intravenously and static imaging is done using Gamma camera after 2-3 hours.
OsiriX is complementary to existing viewers, in particular to nuclear medicine viewers. It can also read many other file formats: TIFF (8,16, 32 bits), JPEG, PDF, AVI, MPEG and QuickTime. It is fully compliant with the DICOM standard for image communication and image file formats.
A PSMA scan is a nuclear medicine imaging technique used in the diagnosis and staging of prostate cancer. It is carried out by injection of a radiopharmaceutical with a positron or gamma emitting radionuclide and a prostate-specific membrane antigen (PSMA) targeting ligand.
A rectilinear scanner is an imaging device, used to capture emission from radiopharmaceuticals in nuclear medicine. The image is created by physically moving a radiation detector over the surface of a radioactive patient. It has become obsolete in medical imaging, largely replaced by the gamma camera since the late 1960s. [1] [2] [3]
Theranostics, also known as theragnostics, [1] is a technique commonly used in personalised medicine. For example in nuclear medicine , one radioactive drug is used to identify ( diagnose ) and a second radioactive drug is used to treat (therapy) cancerous tumors .
