Studies comparing imaging modalities require a precise knowledge of the type and location of tissue structures. When comparing cross-sectional techniques such as ultrasound, computed tomography, and magnetic resonance imaging, the images must be obtained through the same tissue section that is examined histologically. An experimental system that permits comparison of these modalities with histologic sections of precisely corresponding tissue is described. Application in 30 gastrointestinal tissue specimens shows a high degree of correspondence between crosssectional images and histologic sections. This method should be useful in tissue imaging research for anatomic correlation and for comparisons between imaging modalities.
