Description / Table of Contents:
Zusammenfassung Die quantitative Bestimmung der Absorption einer125J-Strahlenquelle durch die Mittelphalanx eines Fingers soll die frühzeitige Erkennung und Verlaufskontrolle von Skeletkalksalzminderungen gestatten. Der vorläufige Normalwertbereich von 86 Probanden deckt sich mit den Angaben in der Literatur, während die Reproduzierbarkeit der Einzel- als auch der wiederholten Messungen deutlich abweicht. Die radiologische Osteoporose bei chronisch niereninsuffizienten Patienten konnte nur in 33% durch die Messung der Absorption am Finger bestätigt werden.
Notes:
Summary Quantitative transmission profile scanning of the middle phalanx of the left forefinger was performed using the method of Börneret al. Normal ranges, different for sex and age, were established by the investigation of 86 patients showing no evidence of bone disease. The evaluation of this method's reproducibility in 5 normal subjects gave the following results: S. D. at five different days 7–35% S. D. at five continuous determinations 3.5–9.0%. Of 47 patients with severe chronic renal insufficiency, 33 showed signs of osteoporosis evidenced by radiological examination. Only in 13 of them were the absorption coefficients significantly decreased. Of the 14 patients without radiological evidence of osteoporosis 7 had normal and 7 other decreased values. It is concluded that the reproducibility of the method is not sufficient for follow-up studies and that the forefinger might not be representative for bone decalcification caused by chronic renal insufficiency.
