title: [Study on renal osteodystrophy using 2-compartment model analysis of bone scintigraphy. 1. Clinical significance of K Index].
abstract: The dynamic analyses of bone scintigraphy were performed in 30 cases of hemodialysed patients. The regression analyses between biochemical data or duration and K indexes obtained from the 2-compartment model analysis in the maxillofacial region were carried out. The obtained results were as follows. 1) The duration and K indexes were significantly correlated with 1 or 2% of significance level in the parietal bone and the zygomatic bone. 2) Serum Ca and K indexes were highly correlated in every settled ROI. The correlation coefficients were distributed from 0.58 to 0.79. In the cranial bone the correlation were more higher than in maxilla and mandibular bone. 3) Serum ALP and K indexes have more higher significant level of correlation than the results of Ca. The correlation coefficients were distributed from 0.48 to 0.83. The level of significance were changed by location. The highest correlation coefficient was 0.83 in the parietal bone. 4) Serum c-PTH and K indexes have significant correlation in every settled ROI with the correlation coefficient from 0.59 to 0.69. The significance level were nearly equal in every location. 5) In the case of subtotal parathyroidoectomy the K indexes which were abnormally high in preoperation showed the tendancy to decrease toward normal range in postoperation. These results indicated that K indexes reflected the bone change caused by renal osteodystrophy. And the K indexes considered to be usefull to estimate the bone improvement.
