[Adaptation of an A.G.S. endo-uterine catheter for hysterographic examination during radium therapy (author's transl)].

The authors propose an endo-uterine catheter which will permit a hysterographic examination to be made during utero-vaginal radium therapy, thus making it possible to check: --that the catheter has advancec correctly after insertion; --that the uterine cavity intact: --that the catheter is in the correct place; --its retention during treatment. By using radio-opaque rings and small balloons in the hysterographic examination, it is possible to locate: --the external orifice of the cervix; --the urethral meatus; --the anterior wall of the rectum and the posterior wall of the bladder. In this way, the target volume is loated with precision, and the length, position and activity of the various radio-active sources can be adapted accordingly.

[A quantitative and quanlitative examination of bone metastases by whole body scanning with 99mTc-pyrophosphate (author's transl)].

The purpose of the present work is to "quantify" bone scanning, in order to calculate indices of localized uptake that will make it possible to differentiate between normal and pathological uptake, and approach an etiologicial diagnosis. The authors use an Elscint dual head whole body scanner and an offline video display calculator. The patient is given 8 mc technetium 99m pyrophosphate 4 hours prior to scanning.
