[11C]-L-Methionine positron emission tomography in the management of children and young adults with brain tumors [PDF]
, 2009 Only a few Methyl-[11C]-l-methionine (MET) positron emission tomography (PET) studies have focused on children and young adults with brain neoplasm. Due to radiation exposure, long scan acquisition time, and the need for sedation in young children MET ...

Detectors in positron emission tomography
Zeitschrift für Medizinische Physik, 2023 Positron emission tomography is a highly sensitive molecular imaging modality, based on the coincident detection of annihilation photons after positron decay. The most used detector is based on dense, fast, and luminous scintillators read out by light sensors. This review covers the various detector concepts for clinical and preclinical systems.

Positron emission tomography in oncology [PDF]
British Medical Bulletin, 2006 Increasing access to positron emission tomography-computed tomography (PET-CT) has resulted in a shift towards functional imaging, being the primary tool in the assessment of viable tumour in oncology patients. In this review, we discuss the basic principles of this evolving technology and the radio-isotopes it employs.

Opportunities for PET to deliver clinical benefit in cancer:breast cancer as a paradigm [PDF]
, 2010 The glucose analogue fluorodeoxyglucose (FDG) has demonstrated enhanced uptake in the majority of tumours as a result of increased uptake and fixation by phosphorylation. It is the most widely used radiotracer in positron emission tomography (PET), being
