PET (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (PET radiopharmaceuticals) in the body. Positrons (ß+) are positively charged beta particles. They are emitted when the atom is proton rich. A positron has only a transient existence. After losing all of its kinetic ene...

conclusions recent treatment, in addition to age, gender and daylight duration were proved as strong independent determinants on bat development and the level of metabolic activity at [18 f] dg pet/ct and should be considered as an important confounding factor in future researches. results one-hundred eighteen studies were recognized to demonstrate foci of fdg bat uptake (3.1%, mean age: 22.7 y...

Abstract Consolidative radiation therapy (RT) for advanced-stage diffuse large B-cell lymphoma (DLBCL) remains controversial, with routine practice continuing to include RT in patients initial bulky disease or residual masses. Positron emission tomography (PET)-computed is a sensitive modality detecting the presence of at end treatment (EOT). A PET-guided approach selectively administering has ...

  Introduction: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GIST has been shown to over-express c-KIT (CD117), the receptor tyrosine kinase. Imatinib (STI571 or Glivec) is a new type of tyrosine kinase inhibitor that selectively inhibits various tyrosine kinases and has been successfully used to trea...

Bladder herniation is an uncommon condition mimicking suspicious metastasis on PET/CT imaging. We report a 67 y/o man with prostate cancer referred for recurrence evaluation with 68Ga-PSMA-11 PET/CT. The scan showed an asymmetric site of intense tracer accumulation in the left inguino-scrotal region with the same SUVmax to the pelvic bladder. Reviewing cross sectional CT i...

  Combined PET/CT scanners now play a major role in medicine for in vivo imaging in oncology, cardiology, neurology, and psychiatry. As the performance of a scanner depends not only on the scintillating material but also on the scanner design, with regards to the advent of newer scanners, there is a need to optimize acquisition protocols as well as to compare scanner ...
