A fracture of the pelvis in a horse can be detected scintigraphically by probe point counting. However, the pelvis is covered by a large and variable muscle mass, and is close to the urinary bladder, both of which can introduce errors. This paper describes an improved technique which uses a larger set of sampling points and analyses the data with a small computer to construct a three dimensional graph of the gamma-ray output across the pelvis, thus helping to improve the interpretation of the data. The scintigraphic plot from a normal horse, three cases of fracture (confirmed by radiography, ultrasound imaging or post mortem examination) and examples of the artefacts produced by isotope in the bladder and by marked muscle wasting are presented.
马骨盆骨折可通过探头点计数进行闪烁扫描检测。然而,骨盆被大量且变化不定的肌肉覆盖,且靠近膀胱,这两者都可能引入误差。本文描述了一种改进技术,该技术使用更大的采样点集,并通过小型计算机分析数据,以构建骨盆伽马射线输出的三维图,从而有助于改进数据解读。文中展示了一匹正常马的闪烁扫描图、三例骨折病例(经X线摄影、超声成像或尸检确诊)以及膀胱内同位素和明显肌肉萎缩产生的伪影示例。
