异物定位在军事临床放射学中是一个重要课题,在野战外科中具有重要地位。异物定位方法不下数百种,归纳起来大致可分为十类,现就每一类中选择具有代表性而又切实可用的方法扼要叙述如下。 异物的定位方法 一、透视法:此为最原始的方法,也是最简单而又应用较广的方法。其优点是:(1)可作多方面的观察,观察范围较广;(2)检查时可用手推动,观察异物在透视下的活动情况,推测其与
The localization of foreign body in military clinical radiology is an important issue, which plays an important role in field surgery. There are no fewer than 100 foreign object localization methods, which can be roughly divided into ten categories. Now, a representative and practical method of selecting each category is briefly described below. Positioning method of a foreign body, perspective: This is the most primitive method, but also the most simple and widely used method. The advantages are: (1) can be used for a wide range of observations, the scope of observation is broader; (2) can be used to promote the hand to observe the foreign body under fluoroscopy activities, speculated that the
