Benefits Nuclear medicine examinations provide unique information—including details on both function and anatomic structure of the body that is often unattainable using other imaging procedures.
A radiologist or other physician who has specialized training in nuclear medicine will interpret Pet ct patient tracking images and send a report to your referring physician.
For example, if you are Pet ct patient tracking examined for heart disease, you may undergo a PET scan both before and after exercising or before and after receiving intravenous medication that increases blood flow to the heart. You should inform your physician of any medications you are taking and if you have any allergies, especially to contrast materials, iodine, or seafood.
A computer aids in creating the images from the data obtained by the gamma camera. It may help to pump breast milk ahead of time and keep it on hand for use after the PET radiopharmaceutical and CT contrast material are no longer in your body.
Individualized instructions would be required if these tracers are used.
Nonetheless, the isotopes used for PET imaging decay so rapidly that after only 24 hours there is no danger of activating a radiation detector. Nuclear medicine diagnostic procedures have been used for more than five decades, and there are no known long-term adverse effects from such low-dose exposure.
The actual CT scanning takes less than two minutes.
But when the results of PET and CT scans are "fused" together, the combined image provides complete information on cancer location and metabolism.
For more information on how a CT scan is performed, see Computed Tomography. Patients are advised in their own interest to let all physicians know about their previous radiological examinations. Test results of diabetic patients or patients who have eaten within a few hours prior to the examination can be adversely affected because of altered blood sugar or blood insulin levels.
Within this machine are multiple rings of detectors that record the emission of energy from the radiotracer in your body. See the Safety page for more information about pregnancy and breastfeeding related to nuclear medicine imaging.
Unless your physician tells you otherwise, you may resume your normal activities after your nuclear medicine scan. The PET scan takes minutes. You should also inform them if you have any allergies and about recent illnesses or other medical conditions.
Because the radioactive substance decays quickly and is effective for only a short period of time, it is important for the patient to be on time for the appointment and to receive the radioactive material at the scheduled time.
You may also be asked to remove hearing aids and removable dental work. These images can then be interpreted by a radiologist on a computer monitor. If your physician has ordered a diagnostic CT, a radiologist with specialized training in interpreting CT exams will report the findings of the CT and forward a report to your referring physician.
CT imaging uses special x-ray equipment, and in some cases a contrast materialto produce multiple images or pictures of the inside of the body.
You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing. Total scanning time is approximately 30 minutes. Injection of the radiotracer may cause slight pain and redness which should rapidly resolve.
When the examination is completed, you may be asked to wait until the technologist checks the images in case additional images are needed. You may be asked to drink some contrast material that will localize in the intestines and help the radiologist interpreting the study.
The risks of the treatment are always weighed against the potential benefits for nuclear medicine therapeutic procedures. By identifying changes in the body at the cellular level, PET imaging may detect the early onset of disease before it is evident on other imaging tests such as CT or MRI. However, the repair mechanisms in the body are quite active and spacing the procedures with suitable time intervals helps reduce radiation effects, as is done in radiotherapy.PET (Positron Emission Tomography) is a powerful diagnostic tool that, in many cases, renders answers that other imaging tests may not provide.
More effective tracking of the results of treatment therapy; Less extensive surgeries and avoidance of some surgeries PET/CT PATIENT.
We try to make all of our patients feel comfortable when having a PET/CT. We understand how nervous you and your family may be at this sensitive time. Radiation protection of patients during PET/CT scanning. Health professionals. RPOP Home; Radiology; Radiotherapy; A PET/CT test has two components: a PET scan and a CT, which are done together.
At the moment there is no formal mechanism to record and track cumulative radiation exposure to a patient, as is done for staff. In addition, manufacturers are now making single photon emission computed tomography/computed tomography (SPECT/CT) and positron emission tomography/computed tomography (PET/CT) units that are able to perform both imaging exams at the same time.
