放射性核素骨显像在发现骨病变上有很高的敏感性,能在X线检查出现异常之前显示骨病变的存在,其假阴性(<3％),假阳性(<5％)均较低。它既能反映骨骼形态,又可反映局部骨骼的代谢和血供状况,对各种骨肿瘤(尤其是转移癌)的早期诊断有重要的临床价值。对一些良性骨病变也有一定的诊断价值。目前核素骨显像己成为临床医学中不可缺少的诊断方法之一,然而,并不是所有的临床医师都了解此点,因而有必要用一些资料来说明此问题,并对骨显像的临床价值进行评述。
Radionuclide bone scintigraphy was found to be highly sensitive to the presence of bone lesions and showed the presence of bone lesions prior to X-ray examination. The false-negative (<3%) and false-positive (<5% low. It can not only reflect the skeletal morphology, but also reflect the metabolism and blood supply status of the local bone. It has important clinical value for the early diagnosis of various bone tumors, especially metastatic cancer. Some benign bone lesions also have some diagnostic value. At present, radionuclide bone imaging has become one of the indispensable diagnostic methods in clinical medicine. However, not all clinicians know this point, so it is necessary to use some data to illustrate this issue and to evaluate the clinical application of bone imaging Value comments.
