Abstract Time-of-flight (TOF) positron emission tomography (PET) traces its origins to the
beginning of PET itself. A brief historical review will be followed by a discussion of the recent …

TOF PET is characterized by a better trade-off between contrast and noise in the image. This
property is enhanced in more challenging operating conditions, allowing for example shorter …

More widespread use of positron emission tomography (PET) imaging is limited by its high
cost and radiation dose. Reductions in PET scan time or radiotracer dosage typically …

Medical radiation accidents and unintended events may lead to accidental or unintended
medical exposure of patients and exposure of staff or the public. Most unintended exposures …

Within a few months of discovery, X-rays were being used worldwide for diagnosis and
within a year or two for therapy. It became clear very quickly that while there were immense …

New imaging technologies utilising X rays and radiopharmaceuticals are continuously under
development. The benefit of computed tomography (CT) has been so dramatic that there is a …

The first dedicated PET/CT centre in Norway was established at the Norwegian
Radiumhospital in Oslo in 2005. Knowing that the introductions of PET-isotopes in nuclear …

Significant staff exposure is generally expected during PET-and PET/CT applications. Whole-
body doses as well as extremity doses are usually higher per procedure compared with …

Our aim was to evaluate the role of forced diuresis in improving the diagnostic accuracy of
abdominopelvic 18F-FDG PET. Methods: Thirty-two patients were enrolled. Besides the …

It is a general consensus that ionizing radiation is oncogenic in nature. Much of this
agreement is based upon observation of increased incidence of carcinoma in a population …
