ATLAS CORRELATING CT SCANS AND HISTOLOGIC ANATOMY OF NORMAL HORIZONTAL SERIAL SECTIONS

This atlas contains a series of paired images correlating the radiologic and histologic anatomy of the normal temporal bone.  

The radiologic images were acquired from the right ear of a 7 year old male with no otologic disease in that ear.  They were acquired on a multidetector Siemens CT scanner in the axial plane with 0.6 mm collimation.  The images were also 0.6 mm with some overlap.  The images provided are reformatted images done from manipulation of the 3D data set.  The images have been arranged from superior to inferior. 

The light microscopic images were acquired from the right ear of a different individual (75 year old male) with no known history of otologic disease.  The cause of death was coronary artery disease.  The postmortem time was 6 hours.  The temporal bone was fixed in 10% formalin, decalcified using EDTA, embedded in celloidin and serially sectioned at a thickness of 20 microns.  Sectioning was done in the axial plane to correspond with the same plane used in the CT scans.  The major landmark used in both sets of images was the bony lateral semicircular canal: the plane of section was parallel to the plane of the lateral canal.  The atlas displays every 20th section stained with hematoxylin and eosin.

The radiologic and histologic images have been paired to show the anatomy at approximately the same level.  The viewer can magnify each image by clicking in it.  Use the right click button on your mouse to download each image to your desktop.
