The size of lentiform nuclei is not only very important for stereotactic neuronal transplantation and pallidotomy, but is also one of the criteria of disease diagnosis. We reported on 100 patients ...evenly distributed by age (about 10 patients in each 10-year range) with equal sex distribution. All had a normal brain CT. We calculated the maximal length and width of lentiform nuclei at the level of the anterior commissure-posterior commissure (AC-PC) line. In addition, the width of the third ventricle and the distance from the midline to the innermost point of the lentiform nuclei were also measured. The mean values were LLNW (left lentiform nuclear width) 18.23mm, LLNL (left lentiform nuclear length) 34.61mm, RLNW (right lentiform nuclear width) 34.47mm, RLNL (right lentiform nuclear length, TVW (third ventricular width) 5.57mm, MLLN (midline to left lentiform nuclear inner margin) 11.34mm, and MRLN (midline to right lentiform nuclear inner margin) 11.31mm. A t-test showed significant differences between men a
