title: Radionuclide scanning of the spleen. Technical modification, normal variants and dimensions.
abstract: In order to cut down the time needed for the preparation of the thermally damaged erythrocytes, the effect of heat was combined with the use of a higher concentration of ACD. Heating of the 51Cr tagged red cells was performed in a water bath, at 50 degrees C for 15 minutes, in the presence of ACD in the ratio of one ml ACD for every 3 ml blood. Using this technique, the obtained splenic scans in 20 normal individuals were excellent in quality. In the posterior view, the spleen was oval with an oblique long axis in 65% of the cases and transverse long axis in another 15%. In the remaining 20% the spleen was globular. The average measurements of the spleen were 10.5 X 7,1 cm, with a circumference of 29.8 cm. By planimetry, the surface area of the spleen averaged (59 +/- 12.4) cm2 (Mean +/- 1 S.D.) In the lateral projection, the surface area of the splenic scan was larger by an average of 40% than the picture obtained through the posterior approach in all the six examined subjects.
