骨密度(BMD)检测中的T值与Z值有何意义? 个体骨密度测量后往往与同种族、同年龄、同性别对照组及同性别年轻人对照组进行比较。这些值或用百分比,或用标准差表示,称为Z-Scores或T-Scores,也就是骨密度测量中所用到的Z值或T值。 1. Z-值的用法 Z值是根据同年龄、同性别和同种族分组,将相应病人的骨密度值...
Finally, patients with high BMD T-scores reported fewer fractures at non-hip/non-spine sites compared to patients with a normal T-score 1.0 to +1.0 (1.3% vs. 6.7%, p-value = 0.06). BMD T-scores > +2.5 at the femur sites are rare, do not increase with aging, and are associated ...
3.But of 24 GIDS patients who had been prescribed puberty blockers, a third had BMD scores in the bottom 2% of their age groups (more that two standard deviations below the mean). 但是在24名服用了青春期阻滞药的GIDS患者中,有三分之一的骨密度评分在其年龄组的最后2%(比平均值低两个标准差以...

(P< .0001). By 2 years after bariatric surgery, regression models predicted a 7.4% decrease for BMC and a 1.5 to 0.1 decrease in BMDzscore. The participants began with above-averagezscores, and thezscores remained above average for age throughout the 2 years of follow-up, despite the ...

BMD diagnostic criteria, based on T-scores and Z-scores, provide a standardized method for identifying individuals with osteoporosis. However, it is essential to interpret BMD results in conjunction with other clinical factors to determine the overall fracture risk and guide appropriate management decisi...

The results of a bone mineral density (BMD) test are typically expressed in terms of T-scores and Z-scores. A T-score compares a person's BMD to that of a healthy young adult of the same gender. A score of -1.0 or above is considered normal, while a score between -1.0 and -2.5...
