Abstract「要旨」99mTcリン酸化合物使用による通常の骨シンチグラフィにて異常所見を呈した55症例63病変に対し, 引き続いて検出器回転型装置によるSPECTを実施し, 骨シンチグラフィの追加検査としてのSPECTの臨床的有用性について検討を行った. SPECTが骨シンチグラフィにて得られた以上の情報を付加したのは, 35部位 (55.6%) であり, SPECTは, 病巣の立体的位置の確定, 病巣の内部状況, 前後像で隠蔽される病巣の検出, 疑陽性部位の精査などに有用と考えられた. また, このうち, SPECT, CT, X線単純写真の3検査をともに施行した24症例30病変を対象として, 各検出率を比較したところ, SPECTはX線単純写真より優れ, CTとは同程度の検出率を示した.

Abstract[Summary] SPECT of bone lesion with Tc-99m-phosphorous compounds as an additional method of bone scintigraphy was evaluated in 63 areas of 55 clinical cases. And the detectability was compared to that of CT (General Electric CT/T X2) and plain radiogram in 30 lesions of 24 cases. Some SPECT images with interest were demonstrated. SPECT system used in this series was PHO/GAMMA LFOV and SCINTIPAC 1200 computer system (Shimadzu). SPECT was performed immediately after taking conventional bone scintigrams. SPECT images were reconstructed from multiprojection images. The time for reconstruction in this series was about 50 seconds per 1 slice. The results of this study were as follows: 1) In 35 (55.6%) of 63 areas, the additional information gathered by SPECT was evaluated to be useful. The utilities of SPECT were especially in demonstrating geometrical relation of multiple lesions, extraosseous lesion, the distribution of radioactivity in morbid bone and in further examination of equivocal area. 2) The detectability of bone lesions by SPECT was nearly equal to CT and superior to plain radiogram.
