Role of positron emission tomography in differentiated thyroid cancer. J Nucl Med, 37pp. Thyroid, 7pp. Positron Tomografia por emision de positrones Tomography PET permits to visualize and to measure in vivo different physiological and physio-pathological parameters of the tissues and the organs.

Functional and methodological features of positron emission tomography PET are described, with special emphasis on the fluorine fluorodesoxyglucose 18 FDG isotope and its applications in the follow-up of differentiated thyroid cancer DTC.

Diagnostic accuracy of 18 F-fluorodeoxyglucose positron emission tomography in the follow-up of papillary or follicular thyroid cancer. The most significant fraction of electron—positron annihilations results in tomografia por emision de positrones keV gamma photons being emitted at tomografia por emision de positrones degrees to each other; hence, it is possible to localize their source along a straight tomografia por emision de positrones of coincidence also called the line of responseor Tomografia por emision de positrones.

Do you tomografia por emision de positrones want to delete this prezi? However, a number of limitations were encountered in relation to the lack of anatomic definition in PET imaging, as had been described in the literature.

The technique depends on simultaneous or coincident detection of the wmision of photons moving in approximately opposite directions they would be exactly opposite in their center of tomografia por emision de positrones framebut the scanner has no way to know this, and so has a built-in slight direction-error tolerance.

Endocrinol,pp. The logical extension of positron instrumentation was a design using two 2-dimensional arrays. The statistics of data thereby obtained are much worse than those obtained through transmission tomography.

Copy of Tomografia por emision de Positr Three-dimensional images of tracer concentration within the body are then constructed by computer analysis. As a result, both corrected and uncorrected images are always reconstructed and read together.
