The value of gallium ((67)Ga) scanning in the diagnosis of septic disease of bone or joint was assessed in 34 patients. The results show a sensitivity of 60 per cent and specificity of 64 per cent. The low accuracy of this method for the detection of bone and joint sepsis (62 per cent) means that gallium scanning can be used only as an adjunct to other investigative techniques.

For a long time, numerous investigators dreamed of using radioisotopes to delineate a malignant tumor as a positive image. However, radiopharmaceuticals clinically sufficient for tumor detection had not yet appeared. The first suggestion, in 1969, that gallium-67( 67 Ga)-citrate might localize in tumors was based on a serendipitous finding by C.I. Edwards and R.L. Hayes.’ Although nearly 20 yea...

Malignant lymphoma is rarely seen in the hand. We present a case of malignant lymphoma of the hand with Ga-67 citrate and MR images, and discuss the usefulness of Ga-67 citrate scintigraphy for diagnosing this condition.

For the establishment of the experimental system to judge easily the effect of anti-inflammatory drug, 67Ga-citrate was used. The weight of granuloma tissues induced by inflammable agent, turpentine oil, gradually increased and reached a maximum at 6 days after the administration of turpentine oil. Gallium-67 accumulation in the inflammatory lesions showed also a maximum at 6 days after that. B...

Thermal noise from test masses, arising both from internal noise in the test mass material and from losses in the suspension wires and their attachments, is a significant factor limiting sensitivity of interferometric gravity-wave detectors. To investigate ways of reducing these noise sources we are using magnetic levitation in place of suspension wires. A search for high-Q crystals with magnet...

We report a novel in vivo spectral imaging approach to cancer detection and chemotherapy assessment. We describe and characterize a ratiometric spectral imaging and analysis method and evaluate its performance for tumor detection and delineation by quantitatively monitoring the specific accumulation of targeted gallium corrole (HerGa) into HER2-positive (HER2 +) breast tumors. HerGa temporal ac...

Dimethylgallium azide (Me2GaN3) and other organogallium azide compounds have attracted recent attention as potential single source precursors for the Chemical Vapor Deposition (CVD) of GaN semiconductor films.1-7 Gallium nitride is important for applications in near-UV solid-state devices such as high brightness blue LEDs and lasers. As part of our interest in the application of single source p...
