Inconsistency in radiographic evaluation of progressive renal osteodystrophy.
Five radiologists graded 49 series of bone X-rays of 20 patients with chronic renal failure treated by hemodialysis. There was a high incidence of osteodystrophy which progressed identifiably over intervals exceeding 12 months. The severity grade of osteodystrophy was poorly reproducible among patients, among radiologists, and even between interpretations by the same radiologist after an interval of 10 months. Although the severity of osteodystrophy correlated with serum alkaline phosphatase values, the latter was not an accurate predictor of the severity of the bone lesions. Radiographic reassessment at intervals of one year or less in the asymptomatic patient has less reproducibility than the anticipated changes. More sensitive and reliable techniques are recommended.
