Radionuclide kidney scan

Radionuclide renal scanning is the application of the kidneys to selectively concentrate and excrete radionuclide-labeled compounds through a scanner in vitro examination to develop the kidneys. Based on the obtained images, the position, shape, size, and radiation distribution density of the two kidneys were analyzed for comparison, and a diagnosis was made in conjunction with the clinical condition. When renal artery stenosis causes renal atrophy, renal scans show that the affected kidney is smaller than normal, the radioactive distribution is sparse, and uneven. The contralateral kidney may have a modern compensatory hypertrophy. If renal artery stenosis has not yet caused changes in renal function, renal scans may show no significant abnormal changes.
