Computed Tomographic Scintigraphy (CTS), also known as SPECT/CT (Single Photon Emission Computed Tomography/Computed Tomography), is a medical imaging technique that combines two separate imaging modalities - nuclear medicine scintigraphy and computed tomography (CT). It is a non-invasive diagnostic tool used to visualize and analyze various structures and functions within the body.
In CTS, a radioactive tracer substance specific to the organ or system being examined is injected into the patient's bloodstream. The tracer emits gamma rays, which are detected by a gamma camera. This camera rotates around the patient, capturing scintillation images from multiple angles. These images are then reconstructed into a three-dimensional representation using CT technology, which provides detailed anatomical images to complement the functional information obtained from the scintigraphy.
The combination of scintigraphy and CT allows physicians to correlate the functional abnormalities detected through the tracer with the precise anatomical location within the body. This enables more accurate diagnoses and helps guide appropriate treatment plans.
CTS is commonly used in the field of nuclear medicine to evaluate a wide range of conditions, including bone disorders, cardiovascular diseases, thyroid disorders, and certain types of cancers. It provides valuable information about blood flow, tissue metabolism, organ function, and the presence of abnormalities or conditions that may not be detected by other imaging modalities.
Overall, Computed Tomographic Scintigraphy is a powerful diagnostic tool that enhances the understanding of both anatomical and functional aspects of the human body, allowing healthcare professionals to provide more precise and targeted care to their patients.
