Description

Renal dynamic imaging assesses kidney function and blood flow to diagnose obstruction, reflux, or transplant complications, with costs typically ranging ¥800–¥1200 in China; ChinaMedicalHub assists with hospital booking and interpreter support.

Main Uses

Renal dynamic imaging is primarily used to assess kidney function, including GFR, differential function between the two kidneys, and to diagnose urinary tract obstructions. It is also useful in evaluating post-transplant kidney function, detecting renovascular hypertension, and monitoring the effects of treatment on kidney function.

Normal Range

The normal range for renal dynamic imaging typically includes a glomerular filtration rate (GFR) of 90-120 mL/min/1.73m², with both kidneys showing symmetrical uptake and excretion of the radiotracer. The time to peak activity (Tmax) is usually within 2-5 minutes, and the half-time of tracer washout from the kidney (T1/2) should be less than 10 minutes.

Low Values - Possible Causes

Possible causes of low values in renal dynamic imaging include chronic kidney disease, acute kidney injury, renal artery stenosis, unilateral or bilateral renal agenesis, and obstruction of the urinary tract.

High Values - Possible Causes

High values or increased tracer uptake in renal dynamic imaging can be caused by conditions such as hyperfiltration (often seen in early stages of diabetes), compensatory hypertrophy of the remaining kidney after nephrectomy, and certain types of renal tumors or inflammation.
