Magnification is an indispensable technique in pediatric nuclear medicine that is used to improve the relatively low resolution characteristics of gamma cameras typically equipped with parallel hole collimators. Magnification scintigraphy is useful for the assessment of diseases of the thyroid, kidney, heart, small bones, and scrotum.2,4–7,10 To achieve magnification the usual parallel hole collimator is replaced by a pinhole collimator or possibly a converging collimator.
