In 12 patients with nephrocalcinosis, radiographs were compared with computed tomography, sonography and histology. Computed tomography detects nephrocalcinosis at a very early stage of the disease, gives a better picture of the density and exten of nephrocalcinosis and may detect other findings (e. g. cysts). Radiographs may show many more details than computed tomography; they seem to be more suitable for observing the course of the disease and have a lower radiation dose. Sonography has not been helpful in the diagnosis of nephrocalcinosis. Histology correlates only moderately with the degree of nephrocalcinosis demonstrated in radiographs and computed tomography.
