Neuroradiol.1983 May 01; 4 AB - An anatomic correlation of sonographic images and anatomy in cadavers was undertaken to establish a foundation for sonographically assisted recognition of structures and their relation to pathology. Such information would be useful for orientation purposes during surgery, for biopsies, and for follow-up studies. A specially designed technique of placing metal markers with sonographically guided needles was used. Anatomic cuts and dissections were subsequently performed. Sonographic clinical material obtained during surgery and in postoperative controls was analyzed based on this experimental work and previous investigations in this area. Detailed anatomy of the posterior fossa can be demonstrated with sonography.
