Renal cyst CT value range

The CT value range of renal cysts is not a fixed number; it is influenced by multiple factors such as the size of the cyst, the concentration of the internal fluid, the presence of calcification in the cyst wall, and the scanner settings. Generally speaking, the CT value range of renal cysts is approximately between 0 and 20 HU, because the interior of the cyst mainly contains liquid material, and its CT value is close to that of water. Some cysts may have densities higher or lower than the renal parenchyma, causing their CT values to deviate from this range. Relying solely on CT values cannot fully determine the severity of a renal cyst; accurate diagnosis requires the integration of other imaging examinations and clinical information. If you suspect you have a renal cyst, it is recommended to seek medical attention promptly and follow your doctor's advice for further investigation and treatment.
