摘要：

The accuracy testing of a new CT-guided stereotactic device was undertaken via an experimental study. Ten dog cadaver heads were submitted to a CT examination and a brain target was determined (coordinates: xl, yl, zl). 0.3 mi of a radiopaque paste was injected in this chosen point. The head was analysed twice by CT and the centre of the injection (x2, y2, z2) was measured on slices. Tridimensional statistical analysis of the variance of the two points was carried out. The procedure always led to the injection of the radiopaque paste and created an intracerebral mass which gave a measurable image on cr examination. The distance between the original target and the centre of the injection was 2.9 +/- 1.08 mm. It is concluded that this new device allows the opportunity to perform stereotactic CT-guided brain biopsy for all unknown brain lesions exceeding 6 mm in diameter in the dog.
