Thirty gallium scans, using currently acceptable dosage levels (5-6 mCi) and a conventional rotating gamma camera, were performed on 20 patients with lymphoma or infection. Compared to planar scans, SPECT increased sensitivity and lesion detection from 48% to 89% in lymphoma, and from 50% to 80% in infection. The predictive value of a negative site was 81% in lymphoma and 67% in infection. Gallium utility is markedly increased by SPECT imaging. A normal gallium SPECT scan is highly accurate in ruling out disease.
使用目前可接受的剂量水平（5 - 6毫居里）和传统旋转伽马相机，对20例淋巴瘤或感染患者进行了30次镓扫描。与平面扫描相比，单光子发射计算机断层扫描（SPECT）使淋巴瘤的敏感性和病变检测率从48%提高到89%，感染的从50%提高到80%。阴性部位的预测价值在淋巴瘤中为81%，在感染中为67%。SPECT成像显著提高了镓的效用。正常的镓SPECT扫描在排除疾病方面具有很高的准确性。
