scintigrafie
Scintigraphy is a nuclear medicine imaging technique that uses small amounts of radioactive tracers, or radiopharmaceuticals, to visualize the function and distribution of organs and tissues within the body. After administration, the tracer accumulates in specific sites according to biological processes, and a gamma camera detects the emitted radiation to create images. Planar scintigraphy provides two-dimensional images, while techniques such as single-photon emission computed tomography (SPECT) produce three-dimensional data; hybrid SPECT/CT combines functional information with anatomical reference from computed tomography.
The radiotracers used in scintigraphy are chosen to target particular organs or pathophysiological processes. Technetium-99m compounds
Common clinical applications include bone scintigraphy for detecting metastatic disease and fractures, thyroid scans for evaluating
Safety and interpretation: Scintigraphy provides important functional information with generally low radiation exposure, but it requires
