Abstract

A three‐dimensional projection reconstruction technique is described for imaging boron‐11 distributions, with potential application to boron neutron capture therapy. The method samples a spherical volume of k space uniformly to obtain a 32 × 32 × 32 matrix with voxel size of 0.42 cm^3^. A signal‐to‐noise ratio (S/N) of 3 was obtained in 8.5 minutes in a phantom containing 75 ug/mL of boron in borocaptate sodium (BSH). Images were obtained in a dog after cessation of an intravenous infusion of BSH and again 30 minutes later, with a maximum boron S/N of about 12. Boron levels in the brain dropped about 6%‐8% and were more diffusely distributed on the images obtained 30 minutes after BSH infusion.

Glenohumeral instability is a common occurrence following anterior dislocation of the shoulder joint, particularly in young men. The bony abnormalities encountered in patients with glenohumeral instability can be difficult to detect with conventional radiography, even with special views. The aim of
