High resolution computerized tomography scans have been used for medical and legal purposes to evaluate patients with a history of exposure to asbestos. Some investigators argue that high resolution scanning provides a better image of the lungs than routine computerized tomography. A review of the literature shows that although high resolution scanning displays the lymphatics in the lung, it offers no new useful diagnostic information. The authors conclude that no real advantage is attained with high resolution scanning of the lung and that pathology of disease can be determined decisively only by histology.

高分辨率计算机断层扫描已被用于医学和法律目的，以评估有石棉接触史的患者。一些研究人员认为，高分辨率扫描比常规计算机断层扫描能提供更好的肺部图像。文献综述表明，尽管高分辨率扫描能显示肺部的淋巴管，但它并没有提供新的有用诊断信息。作者得出结论，肺部高分辨率扫描没有真正的优势，疾病的病理只能通过组织学来明确判定。
