What is a three -phase scanning of bones?
A special type of test of medical imaging known as a three-phase scanning of bones recommends doctors in an attempt to diagnose a condition known as osteomyelitis-bacterial bone infection and its pulp. This examination of nuclear medicine involves injection of a small amount of radioactive material into the bloodstream. Then three series of scans are performed at three different times.
The first images in the three-phase scanning bone are taken almost immediately after the injection of a radioactive isotope, often called Technetium-99. The second phase comes four hours later. The final series takes place 24 hours after the shot. For each series of photographs, the patient lies only on the table for 20 minutes and hour. Patients may occasionally be asked to move the position for a set of images aimed at a particular part of the body.
Unlike other nuclear medicine tests, patients can eat and drink before three -phase bone scanning. Before the test, they may also be asked to drink additional water to prevent radi buildingOive material in the bladder. Patients are asked to empty the intestines regularly and drink other water between each of the three scanning. The isotopes of Technetium-99, generally called radionuclide traces or radiotracery, are usually injected into the cheater of the elbow.
The whole body will often be scanned during a three -phase bone scan. This is done by a gamma camera that records places that absorbed the largest amount of radionuclides. This information can then be used to identify areas in bones where osteomyelitis has been rooted. Because it could disrupt the results, jewelry must be removed before most nuclear medicine. It should also be prevented from over-the-counter medicines such as Pepto-Bismol® because they contain a metal element called bismuth-deotop, which CNar disturb the results.
There is also a shorter version of three -phase bone scanning. This test is used to DIagostics of bone metastatic disease, which is a form of cancer. Only an immediate range of pictures and another series about four hours later is that all doctors need to identify this condition that is characterized by cancer cells spreading from one part of the body to another. Several other types of bone scans are regularly carried out to identify cancer tumors, hardly fractures and a number of metabolic disorders.
