introduction: [64cu]diacetyl-bis(n4-methylthiosemicarbazone) ([64cu]atsm) is a well-established hypoxia imaging tracer with reproducible production and significant specifity. in this work the high yield production and quality control as well as imaging studies in healthy rabbits is reported. methods: copper-64 produced via the 68zn(p,an)64cu nuclear reaction (30 mev protons at 180 µa) was used...

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...

Coincidence imaging is a technique that extracts an image of a test system from the statistics of photons transmitted by a reference system when the two systems are illuminated by a source possessing appropriate correlations. It has recently been argued that quantum entangled sources are necessary for the implementation of this technique. We show that this technique does not require entanglemen...

this paper intends to compare the abilities of the two major imaging modalities in nuclear medicine imaging: positron emission tomography (pet) and single photon emission computed tomography (spect). the motivations are many-fold: (i) to gain a better understanding of the strengths and limitations of the two imaging modalities in the context of recent and ongoing developments in hardware and so...
