Indicated for: diagnostic imaging
Route of administration: injectable
Substance: Tc 99m-exametazime (contrast agent)
ATC: V09AA01 (Various | Central nervous system | Technetium (99mtc) compounds)
Tc 99m-exametazime is a radiopharmaceutical substance used in nuclear medicine to diagnose certain brain conditions, such as Alzheimer’s disease or other forms of dementia. This substance contains technetium-99m, a radioactive isotope that allows visualization of brain activity through SPECT scanning (single-photon emission computed tomography).
It is administered by intravenous injection, and the procedure is painless. After administration, the patient undergoes a scan that usually lasts between 30 and 60 minutes. It is important to follow the medical staff’s instructions before and after the investigation to ensure accurate results.
Side effects are rare but may include mild allergic reactions, such as skin rashes or itching. Radiation exposure is minimal and considered safe for most patients. If you have known allergies or other health issues, inform your doctor before the procedure.
Tc 99m-exametazime helps doctors obtain detailed information about brain function, facilitating the diagnosis and monitoring of neurological diseases. The investigation is safe and useful for establishing an appropriate treatment plan.
