The data were acquired using a triple head gamma camera (Trionix, Triad XLT) equipped with low-energy high-resolution parallel beam collimators in a 128 × 128 detector element matrix over 360 degree orbits, with 120 views obtained at 3-degree intervals for 30 s per view following a circular orbit with a radius of 218 mm. The photopeak energy setting was at 140 keV with an 18% window. Transaxial images were reconstructed in a 128 × 128 matrix with attenuation correction and collimator modeling and 3.2-mm cubic voxels using the OSEM algorithm in ten iterations, OS = 30, a Butterworth post-filter (order = 5, cutoff = 1.0 cycle/cm). The reconstructed system resolution was approximately 12 mm full width at half maximum (FWHM). The images were viewed in the usual three orthogonal planes (coronal, sagittal, and transaxial) and as maximum intensity projection objects. Special care was taken to obtain good visualization of the posterior fossa and brainstem.
