Three-dimensional bone scintigraphic images were made and their usefulness and limitations discussed.
After usual bone scan procedures, single-photon emission computed tomography (SPECT) data were taken and reconstructed into three-dimensional images. Volume rendering methods were used.
Three cases of three-dimensional bone scintigraphy were obtained; one of a normal patient, one of a case of transplanted kidney and incomplete fracture of the left femoral head, and one of a case of degenerative joint disease (DJD) on the left temporomandibular joint (TMJ). The three-dimensional structure of the skeletal system was depicted more clearly by the three-dimensional images than by a conventional bone scan.
Three-dimensional bone scintigraphs were thought to provide additional information for better understanding of the nature of bone lesions. Some technical improvements including automated threshold level determination and feature extraction for detecting abnormal high uptake are required before routine use can be envisaged.
制作了三维骨闪烁显像图像，并讨论了其用途和局限性。
在进行常规骨扫描程序后，获取单光子发射计算机断层扫描（SPECT）数据并重建为三维图像。使用了容积再现方法。
获得了3例三维骨闪烁显像病例；1例正常患者，1例肾移植且左侧股骨头不完全骨折患者，1例左侧颞下颌关节（TMJ）退行性关节病（DJD）患者。三维图像比传统骨扫描更清晰地描绘了骨骼系统的三维结构。
三维骨闪烁显像被认为可为更好地理解骨病变的性质提供额外信息。在设想常规使用之前，需要进行一些技术改进，包括自动阈值水平确定和用于检测异常高摄取的特征提取。
