The bone scan remains useful in well–defined stages of disease, and palliative therapeutic options are evolving. At present, monoclonal antibodies and PET are not very useful in daily clinical practice. 展开 关键词: Prostate carcinoma · Radionuclide imaging · Scintigraphy · ...
Bone scintigraphy Also commonly called a bone scan, this is an imaging test specific to the skeleton. It may be used to look for fractures not easily visible on an x-ray, to help diagnose the cause of bone pain, to look for infections in the bone (called osteomyelitis), and to look ...
Our findings indicate that most patients (64%) with cancer who underwent a routine bone scan to check for metastatic disease had intense stress related either to the results or the side effects of the examination. However, there were more patients who were concerned about the results of the ...
Child abuse:Non-accidental injury in babies and children is a challenging clinical conundrum. Diagnosis is crucial, and a high suspicion should always be maintained. Bone scan offers a high sensitivity exam that adds value as an adjunct to the traditional skeletal survey.[121][122][123][124][...
THE EFFECTS OF NUCLEAR RADIATIONS JERRY B. MARION, in Energy in Perspective, 1974 THE OTHER SIDE OF THE COIN Lest the reader be left with the impression that all nuclear radiations are “bad,” brief mention should be made of the fact that these radiations have been used in many ways ...
the 3-dimensional (3D) acquisition of radiation sources that emit either monoenergetic (radiations with single energy) or polyenergetic (radiations with multiple energies) photons, such as technetium 99m and iodine 131, from all around the radioactive source (seeImage.Technetium 99m MDP Scan). ...
(prostatic bed/prostate gland:n = 27; LN:n = 12; bone:n = 16). All pathologic lesions showed tracer uptake within the first 3 min, whereas urinary bladder activity was absent within the first 3 min of dynamic imaging in all patients. SUVmaxwas significantly higher in PC ...
If side effects (flushing, chills, or nausea) occur, the dose is decreased as tolerated. The 90Y-labeled preparation is injected slowly by hand during 10 minutes through a Millipore filter using a syringe in an acrylic shield. As stated previously, in the United States and Canada, 186 MBq...
due to the changes in active bone marrow during childhood development. Therefore, careful consideration of radiationinduced myelosuppression is essential during protocol optimization for pediatric patients receiving radiotherapy outside the pelvic region.

The effects of growth factors (G-CSF and GM-CSF) on FDG biodistribution (due to enhanced bone marrow uptake) generally last for more than 2 weeks after the final administration [20]. It is assumed that the (side) effects of radiotherapy are longer-lasting; investigation of patients with hea...
