Ovarian and Endometrial Uptake in 18F FDG PET CT


Ovarian and Endometrial uptake in 18F FDG PET CT is common and dependent on the time of imaging with relation to the menstrual cycle. These findings should be interpreted carefully.

Thymus 18F FDG Uptake - Normal Variant or Hyper- stimulation


The above image shows the standard normal biodistribution of 18F FDG uptake in a patient imaged with 18 F FDG.

Please click on the image or link above to view the PDF of teaching files on increased thymus uptake which can happen as a normal Variant due to hyper-stimulation of thymus post chemotherapy. This could be misinterpreted as active disease in many a situation.

The Role of PET/CT in Radiation Treatment Planning for Cancer Patient Treatment


 IAEA TEC DOC on PET CT in RT Planning

Clinical PET, combined with utilization of 18F-FDG, may have an important role in radiation treatment planning (RTP) in lung cancer. In addition to determining if RT is appropriate and whether therapy will be given with curative or palliative intent, 18F-FDG-PET is useful for determining therapy ports. It can be used both to limit ports to spare normal tissue and to include additional involved regions. Several studies have shown that PET has an impact on RTP in an important proportion of patients. It is to be hoped that treatment plans that include all the 18F-FDG-avid lesions or the 18F-FDG-avid portions of a complex mass will result in more effective local control with less unnecessary tissue being treated.
The IAEA has placed emphasis on the issue of application of clinical PET for radiation treatment planning in various cancer patients.
