Techniques for the diagnosis of<unk>  are all imaging based, including abdominal x-ray, intravenous pyelography, angiography, renal doppler ultrasound, CT scan, and Magnetic resonance imaging (MRI). X-ray and pyelography may add in diagnosis, but are non-diagnostic when used alone. Additionally, pyelograms use potentially nephrotoxic contrast agents, further limiting their utility. Diagnosis is primarily made using ultrasound and CT. CT and MRI imaging can show the space occupying lesions but doppler ultrasound is needed to display the hemodynamic changes occurring in the kidney. Ultrasound is often the initial diagnostic test of choice but due to its low resolution further imaging may be necessary.
