How big are your kidneys?

Kidney Size is Measured with Imaging

Determining kidney size
	Your kidney doctor works with a radiology team, who specializes in imaging. Measurements taken during the imaging tests help calculate the volume of the kidneys (how big they are compared to a healthy kidney). Knowing how big your kidneys are at the time of your imaging scan, can help predict how badly your kidneys are being damaged, and how quickly you may reach kidney failure.
MRI and CT Imaging
	Magnetic resonance imaging (MRI): a large tube scanner uses a magnet, radio waves, and a computer to create an image. Computed tomography scan (CT or CAT): this scanner typically looks like a large donut and uses x-rays and a computer to create an image.
Ultrasound imaging
	If an MRI or CT scan is not an option, your doctor may perform an ultrasound. Ultrasound imaging does not use dyes or radiation. This imaging test is like the one used in pregnant women; however, they will be taking pictures of your kidneys. Kidney length is measured and can help doctors predict how badly your kidneys are being damaged and how quickly you may reach kidney failure.
