Complications of cholecystitis and/or biliary colic may also include cholangitis, sepsis, pancreatitis, hepatitis, and choledocholithiasis (10%). In addition, Gallbladder perforation occurs in 10% of patients with cholecystitis. When perforation is localized, it may be seen as pericholecystic fluid by ultrasonography.
Half-life is defined as the time it takes for one half of a radioactive element to decay into a daughter isotope. As radioactive isotopes of elements decay, they lose their radio activity and become a brand new element known as a daughter isotope.
The following table lists ALL radioactive nuclei with a half-life greater than 1000 years. An element decays away below detectable levels in about ten to fifteen half-lives. * Common means the isotope comprises more than 1% of the local atomic abundance of its element. Rare means it has an abundance of less than 1%.
