A fast diagnosis (6h) of clinically latent pyonephrosis by combined use of 99mTc-MDP and 67Ga-citrate is reported. This technique combines the potential early detection of focal infectious processes by 67Ga and the "high-pulse" separation possibility of multiple isotopes. A brief prospective study (

β¦ Synopsis
The difficulty of clinical and radiographical diagnosis of hepatoma is discussed. A case of hepatoma is reported. Both the primary tumor and distant metastases showed strong avidity for 99mTc-HIDA, which normally is concentrated by parenchymal cells of the liver. The potential of using 99mTc-HIDA for the noninvasive investigation of patients suspected of having hepatoma is discussed. The association between tumor avidity for 99mTc-HIDA and the bile-forming ability of tumor cells is of interest.

Interpretation of the posterior view of an 111In-labelled leucocyte scan is difficult when infection is suspected in that region of the spine overlaid by the left lobe of the liver. A case is reported of the successful localisation of infection in this region by combining an 111In-labelled leucocyte
Images were obtained both with a biliary agent, 99mTc-Sn-N-pyridoxyl-5-methyltryptophan (99mTc-PMT), and with 67Ga-citrate in 40 cases of hepatocellular carcinoma and in 43 cases of other hepatic diseases and results were compared. Positive results were obtained by delayed 99mTc-PMT imaging in 25 (6
## Abstract Venous malformations of the small intestine are rare in children, and the preoperative diagnosis of a venous malformation in the small bowel can be very difficult. We report the case of a 2βyearβold girl with a solitary cavernous venous malformation of the small intestine that caused ga
