英文摘要 | Background: A picture archive and communication system (PACS) for bone scan images was established between the departments of nuclear medicine and radiation therapy. The performance of the PACS and the differences between clinical interpretations made using bone scan images from the PACS and those made using transparent films were assessed. Methods: Seventy bone scans were interpreted on a PACS monitor and with transparent films. There were 20 normal scans, 20 scans of multiple bone metastases, and 30 scans with one to several hot spots. Sensitivity tests, specificity tests, and receiver operative characteristic (ROC) analysis were performed and compared between the two viewing modalities. Results: The average image access time was 1.53 (± 0.27) seconds. The correlated area test of ROC analysis showed statistically significant difference between viewing modalities, and better diagnostic performance for interpretation of bone scans using PACS. Conclusions: The study reveals significantly better interpretation performance of bone scans with PACS than with transparent films. |
