Preliminary report on digitalization of renal microangiograms used in analysing renal parenchymal diseases.
Glomerulography is a useful method for the angiographic diagnosis of various renal parenchymal diseases. A new system for digitalization of the glomerulogram has been developed using a high resolution television camera and a CT computer. We describe the fundamental procedures involved in the clinical application of digital glomerulography by applying this method to a renal microangiogram of a cow. This new method aids a clearer understanding of the detailed microvasculatures by providing better magnification and storage and allowing for further processing of the original analogue images. With a computer printout of any part of the glomerulogram also possible, an estimation of the glomerular counts and their distribution can now be given for any unit of cross-sectional area of the renal cortex.
