The result difference of the accuracy that 16 helix CTA diagnoses to aneurism and DSA does not have statistical significance.

结果329例中的181例患者发现202个颅内动脉瘤。4个动脉瘤CTA漏诊，而DSA检查过程中7个动脉瘤未能清楚显示。16层螺旋CTA诊断所有动脉瘤的敏感性、特异性和准确性分别是98%、98%和98%。16层螺旋CTA对于动脉瘤诊断的准确性和DSA的结果差别没有统计学意义。

However,there have been no papers which have investigated Minkowski and Minkowski slant helices and Minkowski conical geodesic curves so far as.In this paper,our major study is to give the definition of Minkowski general helix and Minkowski slant helices and Minkowski conical geodesic curves in indicators 1 in pseudo-Euclidean three-space (that is, three-dimensional Minkowski space), and study the definition of equivalence Minkowski general helix, By considering geometric invariants of these space curves, we can estimate the order of contact with those special curves for general space curves.
