Tomografia a emissione di positroni
La procedura inizia con l'iniezione di un radiofarmaco formato da un radio-isotopo tracciante con emivita breve, legato chimicamente a una molecola attiva a livello metabolico, detta vettore.
Dopo un tempo di attesa, durante il quale la molecola metabolicamente attiva (spesso uno zucchero) raggiunge una determinata concentrazione all'interno dei tessuti organici da analizzare, il soggetto viene posizionato nello scanner.
L'isotopo di breve vita media decade, emettendo un positrone. Dopo un percorso che può raggiungere al massimo pochi millimetri, il positrone si annichila con un elettrone, producendo una coppia di fotoni gamma entrambi di energia 511 KeV emessi in direzioni opposte tra loro (fotoni back to back).

Lightpoint Medical and Surgical Collaborators Receive £1.7M in Grant Funding for Intra-operative Imaging TechnologyLightpoint's technology uses molecular imaging to rapidly identify cancerous tissue during surgery. In contrast to competing approaches, Lightpoint's technology takes advantage of imaging agents already approved by the health authorities and in widespread clinical use. More details on the clinical trial in breast cancer surgery can be found on Clinicaltrials.gov http://clinicaltrials.gov/ct2/show/NCT02037269. (PR Newswire - 10/03/2014) Leggi
Piramal Imaging Announces EU Approval of NeuraCeq™ (florbetaben 18F)* for PET Imaging of Beta-Amyloid Neuritic Plaque Density in the BrainWith this authorization, NeuraCeq™ will soon be available to provide valuable information that may give physicians more confidence in their clinical assessment and help them provide more personalized patient management as a negative scan may rule out AD as a cause of a patient's cognitive decline.

Concise Analysis of the International Nuclear Medicine Market & Radiopharmaceuticals - Trends & Forecast to 2017Radiopharmaceuticals are drugs that contain radionuclide-emitting ionizing radiation and are used for disease diagnosis and treatment. They provide increased understanding of diseases as they not only give anatomical but also functional information about the organ. Radiopharmaceuticals are also used in the nuclear imaging field as tracers. They are mostly used for diagnosis with the use of gamma cameras for imaging techniques such as in SPECT and PET. Radioisotopes are used in medical applications with more than 90% share. Medical application is driven by the increasing patient population and new and effective radioisotopes. The most commonly used isotopes for diagnosis are Tc-99m and Tl-201 for SPECT and F-18 for PET.The radiopharmaceuticals market is broadly classified into two segments, namely, diagnostic and therapeutic; the former dominated with about 85% share in 2012. Radioisotopes in the diagnostic market are categorized as SPECT and PET. Technetium 99m (Tc-99m) dominated the... (PR Newswire - 12/02/2014) Leggi
MR Solutions is setting the pace in the pre-clinical scanning market with a range of ground-breaking innovations. It was only a few months ago that they announced that their cryogen free 3T MRI range could now be fitted with a clip-on SPECT camera and incorporate a state-of-the-art PET ring inside the machine. The new range of 7T scanners can also be fitted with these SPECT and PET capabilities. (PR Newswire - 10/02/2014) Leggi
