Measurement of mean trabecular plate thickness by a new computerized method.

Mean trabecular plate thickness (MTPT) has been measured by a new direct computerised method on an IBAS II image analyser in iliac crest bone from 56 normal subjects. The new method has been shown to be accurate and reproducible; apart from some initial editing of the image, it is carried out automatically without any need for observer interaction. A close correlation was found between values for MTPT obtained using the new direct method and values obtained by calculation based on area and perimeter measurements made on the IBAS II (r = 0.98).
