作者进行了一项临床研究，以确定双能量数字X线摄影在显示结节钙化方面的准确性，因为肺结节中的钙化几乎排除了恶性肿瘤的可能性。在6个月的时间内，61名患有肺结节的患者（≤3 cm）或肿块（> 3 cm）在原型扫描投影单元上使用双能量探测器进行检查。在61例患者中，49例结节未钙化，12例钙化。在57例患者中，38例通过病理证实，19例通过强有力的推断（4例非钙化孤立性肺结节患者拒绝进一步检查或手术，或随访时间太短，无法排除恶性），确定结节的良性或恶性。双能量X线摄影被认为是高度准确的评估存在或不存在钙化的肺结节，从而确定他们的良性或可能的恶性。
The authors undertook a clinical study to determine the accuracy of dual-energy digital radiography in revealing nodule calcification because calcification in a pulmonary nodule almost excludes the possibility of malignancy. Over a 6-month period, 61 patients with pulmonary nodules (.ltoreq. 3 cm) or masses (> 3 cm) were examined on a prototype scanned projection unit using a dual-energy detector. In 49 of 61 patients, nodules were noncalcified, and in 12, they were calcified. In 57 patients, the benignancy or malignancy of nodules was established beyond reasonable doubt by pathologic confirmation in 38 and by strong inference in 19 (four patients with noncalcified solitary pulmonary nodules either refused further investigation or surgery or their follow-up was too short to permit exclusion of malignancy). Dual-energy radiography was found to be highly accurate in assessing the presence or absence of calcification in pulmonary nodules and thus in determining their benignancy or possible malignancy.
