Introduction SPECT is a nuclear medicine tomography imaging technique using gamma rays. Emission of single photon from decay process. Dynamic imaging modality where a series of images are obtained. Image obtained in 3 planes. Obtained by different angles. Reconstruct the layer. Principle Radio isotope is delivered to the patient -> Attaches to specific ligand inContinue reading “SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY”

POSITRON EMISSION TOMOGRAPHY(PET)
Introduction A nuclear medicine imaging technique which provides high resolution tomographic images of bio- distribution of a radiopharmaceutical/ radio tracers in the body. A PET scan measures important body functions – blood flow, oxygen use, sugar(glucose) metabolism, to help the doctor how well organ and tissue are functioning. Mechanism A radioactive isotopes that decays byContinue reading “POSITRON EMISSION TOMOGRAPHY(PET)”
