BACKGROUND In early breast cancer, the optimal technique for sentinel lymph node biopsy (SLNB) is the combined technique (radioisotope and Patent Blue V) which achieves high identification rates. Despite this, many centres have decided to stop using blue dye due to blue-dye-related complications (tattoo, anaphylaxis). We evaluated the SLNB identification rate using the combined technique with a...
Radio-opaque markers have a well established role in distinguishing between patients with normal and those with slow intestinal transit, but in the latter group their accuracy in defining the region of delay has not been established. To study regional colonic transit accurately the transit of a radioisotope labelled meal was determined and findings were compared with those of simultaneously ing...
Radioisotope renography provides, from the individual kidney, a graphic record of the renal vascularity, of the excretory funtion of the tubular cells, and of the evacuatory capability of the tubules and the kidney pelvis. By the use of additional scintillation counters, an index of the rate of extraction of the isotope from the blood and its rate of accumulation in the bladder can also be obta...
