Cardiac amyloidosis is the most common cause of restrictive cardiomyopathy outside tropics. Two main forms: AL amyloidosis (acquired) and transthyretin-related (ATTR) amyloidosis
Discovered by Seaborg and Livingood in 1938 at Berkeley. Produced by neutron irradiation of natural tellurium in nuclear reactors. Contains 78 neutrons, making it the only stable iodine isotope
Radionuclides are unstable nuclides with excess neutrons or protons. About 730 radionuclides have half-lives longer than 60 minutes. Natural radionuclides include primordial, secondary, and cosmogenic types. Artificial production occurs in reactors, cyclotrons, and generators
Medical physics applies physics to prevent, diagnose and treat human diseases. Became recognized as health profession in 2008 by ILO. Medical physicists specialize in radiation oncology, imaging, nuclear medicine
Perfusion refers to fluid passage through circulatory system to organs. Measured as blood flow rate per unit tissue mass (ml/min/g). All animal tissues require adequate blood supply for health
Radiology uses imaging to diagnose and monitor diseases. Wilhelm Röntgen discovered X-rays in 1895. Radiologists require 12 years of education including medical school. Radiation technologists assist radiologists with imaging instruments
