RATIONALE AND OBJECTIVES
To evaluate the usefulness of temporal subtraction using the bone suppression method in digital chest radiography for the detection of pulmonary lesions.
MATERIALS AND METHODS
The images of 31 patients with pulmonary lesions and 19 normal cases were included in the study. Conventional and bone suppression temporal subtraction were performed in the 50 cases selected and used for an observer performance study. Five radiologists participated in the study, and the differences between using conventional and bone suppression temporal subtraction were assessed using jackknife free-response receiver operating characteristic analysis.
RESULTS
The average figure-of-merit values for all radiologists increased significantly using the bone suppression method, from 0.619 (conventional) to 0.696 (p = 0.032). The average sensitivity for detecting pulmonary lesions improved from 67.9% to 75.4%, and the average number of false-positive per case decreased from 0.336 to 0.252 using bone suppression temporal subtraction.
CONCLUSION
Bone suppression temporal subtraction processing can assist with the detection of subtle pulmonary lesions in digital chest radiographs.
原理与目的
评估在数字化胸部X线摄影中使用骨抑制法进行时间减影对检测肺部病变的有效性。
材料与方法
本研究纳入了31例肺部病变患者和19例正常病例的图像。对所选的50例病例进行了常规和骨抑制时间减影，并用于观察者性能研究。5名放射科医生参与了该研究，使用留一法自由反应接受者操作特征分析评估了使用常规和骨抑制时间减影之间的差异。
结果
使用骨抑制法时，所有放射科医生的平均品质因数显著提高，从0.619（常规）提高到0.696（p = 0.032）。使用骨抑制时间减影时，检测肺部病变的平均敏感性从67.9%提高到75.4%，每例的平均假阳性数从0.336减少到0.252。
结论
骨抑制时间减影处理有助于在数字化胸部X线片中检测细微的肺部病变。
