In 1003 patients with a total of 2467 clinically or scintigraphically suspect skeletal parts, conventional x-ray examination at the time of first study resulted in 95% of cases (2331 skeletal parts) in a correct diagnosis. Computed tomography permitted an exact diagnosis in 52% of roentgenologically equivocal findings (136 skeletal parts). In 40% of these patients even by computed tomography metastasis was only suspected, in 8% there were unspecific findings, while by follow-up bone metastasis was proven. In 64.8% of the whole patient collective there were metastatic destructions and in 32.6% of patients benign lesions were found. Superiority of CT compared to conventional x-ray diagnosis resulted from exact demonstration of the intra- and extraosseous extent of lesions and the possibility of density measurements. It depended mainly upon the localisation of the pathologic process.
在1003例共有2467个临床或骨闪烁显像怀疑的骨骼部位的患者中，首次检查时的传统X线检查在95%的病例（2331个骨骼部位）中得出了正确诊断。计算机断层扫描在52%的X线检查结果不明确的病例（136个骨骼部位）中实现了准确诊断。在这些患者中，40%即便通过计算机断层扫描也仅怀疑有转移，8%有非特异性表现，而通过随访证实有骨转移。在整个患者群体中，64.8%有转移性破坏，32.6%的患者发现有良性病变。计算机断层扫描相比传统X线诊断的优势在于能准确显示病变的骨内和骨外范围以及进行密度测量的可能性。这主要取决于病理过程的部位。
