Bone mineral measurement using an EMI scanner and standard methods: a comparative study.

B R Pullan, T E Roberts

The British Journal of Radiology

|January 1, 1978

Summary

A modified EMI brain scanner offers superior sensitivity for measuring bone density compared to traditional methods. This advanced technique can also assess trabecular bone, a key indicator of bone mineral changes.

Area of Science:

Medical imaging
Bone densitometry
Radiology

Background:

Established methods for bone mineral content analysis include scanning photon densitometry and radiographic microdensitometry.
These techniques have limitations in sensitivity and ability to assess specific bone structures.

Purpose of the Study:

To compare the sensitivity of a modified EMI brain scanner with established methods for bone mineral content analysis.
To evaluate the capability of the EMI method in measuring trabecular bone density.

Main Methods:

Comparative analysis of bone densitometry techniques.
Utilized a modified EMI brain scanner alongside scanning photon densitometry and radiographic microdensitometry.
Assessed sensitivity to changes in bone density and visualization of trabecular bone.

Main Results:

The modified EMI brain scanner demonstrated significantly higher sensitivity to bone density changes compared to scanning photon densitometry and radiographic microdensitometry.
The EMI method successfully visualized and measured the density of trabecular bone.

Conclusions:

The modified EMI brain scanner represents a more sensitive method for bone mineral content analysis.
Its ability to measure trabecular bone density offers advantages for detecting early changes in bone health.
