Hemobilia detected by Tc-99m labeled red blood cells
Clinical Nuclear Medicine
|January 1, 1982
Abstract:
Tc-99m labeled red blood cells were successfully used to determine the site of hemorrhage in a 67-year-old man with hemobilia. A false hepatic artery aneurysm was confirmed at angiography and ultimately successfully embolized. The relative merits of using Tc-99m labeled red blood cells for detecting sources of upper gastrointestinal bleeding are discussed.

01:24Hemoglobin
Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...

01:10Blood Typing
Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target antigens A,...
