A result that is not likely to occur randomly, but rather is likely to be attributable to a specific cause. Statistical significance can be strong or weak, and is important to research in many math-and science-related fields, including medicine, sociology, psychology and biology.
A nuclear scan is an imaging test that uses imaging technology and trace amounts of radioactive materials, called radiotracers, to diagnose and monitor diseases and treatments. Nuclear scans can show the structure and function of most body organs and tissues.
A bone scan is used to examine the bones for damage caused by cancer or another disease. It is a nuclear medicine test, which means that a very small amount of a radioactive substance is used during the procedure.sually the entire body is scanned during this procedure. If the results show bone damage that may be caused by cancer, more tests may be necessary. These tests may include a computed tomography (CT) scan, magnetic resonance imaging (MRI) , or a biopsy.
