Descriptor Spanish: Pirofosfato de Tecnecio Tc 99m
Descriptor pirofosfato de tecnecio Tc 99m
Scope note: Radionúclido utilizado en estudios de imagen, principalmente en cintilografía o tomografía cardiaca, para evaluar la extensión del proceso necrótico miocárdico. Ha sido utilizado también en pruebas no invasivas para la distribución de la afectación de los órganos en diferentes tipos de amiloidosis y para la evaluación de la necrosis muscular en las extremidades.
