Computed Tomography (CT) breast diseases. It is used as both is an imaging test that helps a diagnostic and screening tool. healthcare providers detect diseases and injuries. It uses a NUCLEAR MEDICINE TECHNOLOGY series of X-rays and a computer to Branch of radiology that involves create detailed images of your the introduction of radioactive bones and soft tissues. substances into the body for both Recording of a predetermined diagnostic and therapeutic plane in the body using an x-ray purposes beam that is measured, recorded, and then processed by a computer POSITRON EMISSION TOMOGRAPHY for display on a monitor (PET) The creation of sectional images of DIAGNOSTIC MEDICAL SONOGRAPHY the body that demonstrate the a medical imaging modality that physiologic function of various uses sound waves to identify and organs and systems evaluate soft tissue structures in is a type of nuclear medicine the human body for disease and procedure that measures pathology. metabolic activity of the cells of Visualization of deep structures of body tissues. PET is actually a the body by recording the combination of nuclear medicine reflections of pulses of ultrasonic and biochemical analysis. waves directed into the tissue.

MADICAL RADIATION SCIENCES 6.Nuclear energy What is Radiation? is the energy that is contained within the is energy that is transmitted by waves nucleus of an atom. through space or through a medium (matter) What is Ionization? is any process by which a neutral atom gains or loses an electron, thus acquiring a net charge. What is energy? Is the capacity to operate or work. SOURCES OF IONIZING RADIATION 1.NATURAL ENVIRONMENTAL RADIATION Results in an annual dose of approximately 3 millisieverts (msv) 2.MAN-MADE RADIATION. Man-made radiation results in 3.2 msv annually. An mSv is the unit of eOective dose. It is used to express radiation exposure of populations and radiation risk in those populations.
