title: Analysis of planar acintigraphic images using the Li-Ma technique.
abstract: A statistics-based approach to comparison of planar scintigraphic images is introduced to provide additional information to subtraction method. The proposed procedure leads to parametric images with better noise properties allowing subsequent statistical analysis. An example of an application of the technique is given using parathyroid scintigrams. The presented technique is not intended to replace the image subtraction method but offers a tool that may help during a diagnosis-making process.
