This time my left arm was scanned as well as my back and hips. Results as follows:
-4.1 (worst measurement -5.1)
Neck -2.4 (total -1.9)
L1 -L4 3.6
L2 -L4 -4
Interesting that the hips are still not too bad so my lowest reading if I accept that is not osteoporosis overall. My bones are tiny and I have broken no bones since childhood.
