IMPROVED TECHNIQUES IN RADIONUCLIDE IMAGING OF PROSTATIC LYMPH-NODES

Summary— Further improvements have been made in the technique of human prostatic lymphoscintigraphy, allowing better anatomical localisation of the areas of uptake of activity. A single median injection into the capsule of 99mTc labelled antimony sulphide colloid has been found to give as good imaging as 2 injections on either side of the midline. By placing markers on the umbilicus, pubic symphysis and both anterior superior iliac spines, a “pelvic grid” can be superimposed on the antero‐posterior view. Further help with accurate localisation may be attained by taking 3 views; antero‐posterior, postero‐anterior and lateral. In 9 instances, prostatic injection was performed without any sedation or anaesthesia. The resulting scintigrams were indistinguishable in quality from those of anaesthetised patients.
