The persistent nephrogram, which appears either as a homogeneous or mottled density kidney, results from delayed passage of contrast into the collecting system.

causes:
pre renal(15%): renal artery stenosis, hypotension.
renal(70%):Glomerulonephritis ,Ac tubular necrosis,papillary necrosis, Acute interstitial nephritis,renal vein thrombosis.
Post renal(15%): obstruction.

The nephrogram is a sensitive indicator of renovascular compromise. An infrequently reported but characteristic nephrographic abnormality is the cortical rim nephrogram. This "rim sign" refers to a thin nephrographic rim outlining a kidney with an otherwise faint nephrogram. The rim nephrogram is a reliable sign of underperfusion of the kidney. It is dependent on collateral capsular vessels supplying the outer renal cortex. Underperfusion can be due to a primary renal artery problem or secondary to compromise of renal artery perfusion because of elevated interstitial or tubular pressure in the kidney. The sign has not been described with systemic circulatory problems.
