1. antero-posterior directions. Contrary to Jeppsson's;Brinker, R.A.;Echoen-,1965
2. findings, the interface reflecting the pineal echo was between brain and cerebrospinal fluid cephalography;antero-posterior directions. Contrary to Jeppsson's Brinker, R.A.; King, D.L.; Taveras, J.M.;Amer. J. Roentgenol,1961
3. Anatomic localization of midline echo in sonograms of the brain;Brylski, J.R.; Izenstark, J.L.;Ibid,1965
4. rather than brain and calcium deposits. That there was a large cerebrospinal fluid space around the pineal body was apparent on examination of the boundaries of the quadrigeminal cistern. This is confirmed by the work of Di Chiro,1961
5. A transducer placed in front or behind the ear will reflect an echo only from the pineal body because of its oval shape and the normal skull curvature. But in a few cases when the temporal bones present a larger surface parallel to each other;de Vlieger, M.;Neurology (Minneap.); Use of echoencephalography,1959
