Diffuse liver uptake on bone scintigraphy is a rare occurrence with only a few reports in the literature. A case of diffusely increased uptake in a patient with acute hepatitis is presented.

A case of unilateral tibial osteomyelitis in a 20-month-old child after bilateral intraosseous infusion (IOI) needle placement is presented. A review of the indications, potential complications, and scan findings is discussed. This case also shows the lack of significant uptake in the noninfected side, suggesting that a three-phase bone scan is of value in differentiating reactive bone from infected bone in patients with IOI.

Left hemispheric blood flow was measured in eight adult Australian sheep prior to and, 1, 4, 30 and 60 min after the injection of endotoxin, E. Coli, 3 mg kg-1 bodyweight, using a radioisotope method. The mean left hemispheric blood flow prior to septic shock was 200 ml min-1 from which it rapidly reduced to 86 ml min-1 (1 min), and after a short recovery gradually decreased to 39 ml min-1 (60 min). Regional cerebral blood flow showed the highest value in the occipital region prior to septic shock, whereas 60 min after the endotoxin administration it reduced to the same low flow level, as in the other areas of the brain.
