Singh's method of the radiological quantitative evaluation of osteoporosis compared with the densitometric method.

The quantitative evaluation of osteoporosis by Singh's radiographic method, which is based on analysis of the trabecular pattern of the upper end of the femur, recognises seven successive grades of bone loss. This method has been shown, by comparison with bone densitometry, to be reliable both for the quantification of osteoporosis and as a screening method for early diagnosis. The method is sufficiently precise, and is not affected by independent factors such as variations of radiographic technique and the individual characteristics of the subject being tested.
