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 time needed for half of the nuclei in a sample to decay is the âhalf-life.â Measured half-lives vary from 10 -22 seconds to over 10 10 years (10 17 seconds) â an enormous range! Note that two half-lives do NOT make a âwhole lifeâ.After half of the atoms decay, we reset the clock.he time needed for half of the nuclei in a sample to decay is the âhalf-life.â Measured half-lives vary from 10 -22 seconds to over 10 10 years (10 17 seconds) â an enormous range!
