title: CT pixel mapping in the diagnosis of small angiomyolipomas of the kidneys.
abstract: In six small renal angiomyolipomas (7-17 mm) the superiority of displaying the CT numbers of pixels within a lesion (pixel mapping) over the usual region of interest (ROI) measurement is described in the detection of small amounts of fat tissue. On precontrast 5 mm CT the ROI measurements were > 0 in four cases whereas pixel maps revealed pixels with values < 0 in six cases.
