Lung CT scans can also be used for identifying osteoporosis, finds study
China: Low-dose computed tomography (LDCT) imaging for lung cancer can also be used to identify patients with low bone mineral density (BMD), according to a recent study in the Journal of Bone and Mineral Research.
Early screening for lung cancer is performed using low‐dose chest CT is used for prevention of the disease. Previously, the researchers have shown the utility of LDCT for measuring trabecular vBMD of the lumbar spine with high precision. The aim of this population based study by Xiaoguang Cheng, Beijing Jishuitan Hospital, Beijing, China, and colleagues was to determine osteoporosis prevalence in China based on the analysis of lumbar spine vBMD derived from LDCT chest scans obtained for lung cancer screening.
In the study, 69,095 adults (40,733 men and 28,362 women) received LDCT scan for lung cancer screening between 2018 and 2019. The data was obtained from a prospective nationwide multicenter population study called China Biobank Project. Quantitative computed tomography (QCT) software and the American College of Radiology QCT diagnostic criteria for osteoporosis were used to derive lumbar spine (L1–L2) trabecular volumetric bone mineral density (vBMD) from these scans.
