正位成像，通常被称为“扫描图”，仍然是测量肢体长度差异（LLD）最广泛使用的成像技术。本研究回顾了其他测量LLD的方法，包括全身站立正位x线片、计算机断层扫描/数字定位图像和微剂量数字扫描。我们提出了七个病例，证明了与全长站立正位x线片相比，扫描图的缺陷。说明性病例为临床医生定期使用全长站立正位x线片作为提供最具临床相关性信息的工具来管理LLD提供了理论依据。(c) 2005年Lippincott Williams & Wilkins。
The orthoroentgenogram, commonly known as the 'scanogram', continues to be the most widely used imaging technique for measuring limb length discrepancy (LLD). This study reviews other methods of measuring LLD including full-length standing anteroposterior radiographs, computed tomography/digital localization image, and microdose digital scanography. We present seven cases that demonstrate the pitfalls of scanograms as compared with full-length standing anteroposterior radiographs. Illustrative cases provide the rationale for the clinician managing LLD on a regular basis to utilize full-length standing anteroposterior radiographs as the instrument that will provide the most clinically relevant information.
