目前，孤立性肺结节的良性或恶性性质的放射学确定依赖于通过比较放射学照片确定的生长特征或通过低峰值千伏荧光透视或胸部CT检测结节中的钙化。另一种方法是通过数字X线摄影分析结节内的光密度。已经描述了两种技术：用激光扫描仪和双能量数字X线摄影数字化胸片的直方图分析。虽然这两种技术仍然是实验性的，但它们提供了优于CT的潜在优势，因为单次射线照相曝光就足够了，从而减少了对患者的辐射剂量，并为患者提供了不太复杂的检查。
Currently the radiographic determination of the benign or malignant nature of solitary pulmonary nodules relies on growth characteristics determined by comparison radiographs or the detection of calcification in the nodule with either low-peak kilovoltage fluoroscopy or CT of the chest. An alternative approach is analysis of the optical densities within the nodules by means of digital radiography. Two techniques have been described: histogram analysis of chest radiographs digitized with a laser scanner and dual-energy digital radiography. Although both techniques remain experimental, they offer a potential advantage over CT in that a single radiographic exposure is sufficient, thus decreasing the radiation dose to the patient and providing the patient with a less complex work-up.
