In this article, we show that 1) computed tomographic (CT)-guided stereotactic infusion of an excitotoxin into the striatum of a nonhuman primate provides a useful neuropathologic and behavioral model for Huntington's disease. 2) High-resolution posi

Positron emission tomography (PET) may provide an ideal means of monitoring the delivery of cells to normal and pathological tissue owing to its high resolution, specificity and three dimensional imaging capabilities. In order to implement such a tec

The authors present a method to reconstruct projection images through assembly in the Fourier domain, rather than by backprojection. By bypassing the rate-limiting backprojection step of filtered backprojection, the proposed algorithm operates more q

Conference Record of the 1991 IEEE Nuclear Science Symposium and Medical Imaging Conference.
A cylindrically shaped PET (positron emission tomography) camera designed to utilize cross-plane events is being developed. A two-dimensional BGO scintillation detector was designed for the camera. It uses a rectangular array of detector elements and

In order to examine the potential of low-Z detector materials for PET (positron emission tomography), a small field imaging system using plastic detectors has been designed. In this system the site of a photon interaction in the detector is located u

We studied the time course of dopamine (DA) terminal loss in three macaca fascicularis injected with MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) intravenously every 10-14 days for up to 389 days. Striatal DA terminal loss was monitored in viv
