Ultrasound assessment of renal cortical brightness in infants: is naked eye evaluation reliable?
Twenty observers estimated renal cortical brightness compared with the liver in 28 ultrasound images. Their judgment was compared with objective densitometer readings. High inter- and intra-observer variation was found. Estimates of brightness of ultrasound images by eye alone should be interpreted with care.
