SPECT全身骨显像诊断骨转移瘤168例报告

REPORT of 168 CASES DIAGNOSIS OF SKELETAL METASTASES W TH SPECT OF WHOLE-BODY BONE IMAGING

报道168例各种骨转移瘤应用SFECT的诊断结果和显像学表现及特点。骨显像和X线诊断的阳性检出率分别为96.4％和80.7％,骨显像中有35.7％病例分别早于X线3～5个月发现骨转移。表明本法对骨转移的诊断具有独特而重要的价值。

The diagnosis results and features of SPECT whole body bone imaging in168 cases is reported. Malignant bone tumors were studied. There was 49.4%(83/168) positive imaging in the group of skeletal metastasis. A comparisonwas made between SPECT imaging and X-ray examination. The positive rateof diagnosis of bone tumors with SPECT imaging was superior to radiography,(96.4 vs 80.7%). In a group of 35.7% (5/14) cases with matastasis, thepositive findings of SPECT imaging was 3～5 months earlier than that of roent-genography. The results indicate that SPECT imaging is more valuable for earlydiagnosis and as reference for therapy and prognosis.
