Spleen imaging

Spleen imaging is to determine the location, size and shape of the spleen and to make a diagnosis of the lesion if necessary. 99mTC heat-denatured red blood cells, 113In-heat-denatured red blood cells or 51Cr-heat-denatured red blood cells are often used. The purpose of spleen imaging examination is to determine the location and size of the spleen, the nature of the spleen mass and lesions, and the presence or absence of a secondary spleen. Basic Information Specialist classification: Digestive examination classification: ultrasound Applicable gender: whether men and women apply fasting: fasting Tips: Drink water before check. Normal value The spleen is visualized by phagocytosis of radioactive colloidal particles by spleen reticuloendothelial cells, and the degree of concentration in the spleen is related to the size of the colloidal particles. 99TCm-sodium phytate particles are small, when the spleen function is normal, the radioactivity concentration in the spleen is less than 20% of the liver, the liver is obviously developed, the spleen is only slightly developed, and when the spleen function is hyperthyroidism, it is obviously developed, so it can generally be used as An indicator of whether the spleen function is hyperthyroidism or progression. The 99Tcm-sulfur colloidal particles have a diameter of 300-1000 nm. Under normal conditions, the spleen concentration can reach 50%-60% of the intrahepatic concentration, and the spleen is clearly developed, so it can be used as a common imaging agent for spleen imaging. Clinical significance Abnormal results: spleen tumors, cysts, abscesses and hemangioma, etc.) and invasive lesions. People who need to be examined: patients with abdominal pain. Precautions Taboo before inspection: drink water. Requirements for inspection: Put on the patient's clothing check. Inspection process 99mTC heat-denatured red blood cells, 113In-heat-denatured red blood cells or 51Cr-heat-denatured red blood cells are often used. The purpose of spleen imaging examination is to determine the location and size of the spleen, the nature of the spleen mass and lesions, and the presence or absence of a secondary spleen. 111In-platelet or 111In-white blood cells can also be used for the examination of spleen imaging, but because 111In is expensive, it is not widely used in China. Simultaneous labeling with 51Cr and 59Fe can detect cell destruction and the location and number of cells produced. Not suitable for the crowd A patient who is sensitive to radioactive colloidal particles. Adverse reactions and risks No complications.
