SANTA MONICA UCLA MEDICAL CENTER NUCLEAR MEDICINE REPORT 

EXAMINATION: BONE ABSORPTIOMETRY-OSTEOPOROSIS EVALUATION 

DATE: 7/3/2006

CLINICAL HISTORY:  Osteoporosis evaluation in a [...]-year-old postmenopausal [fe]male.

COMPARISION: None 

TECHNIQUE:  With the patient in the supine position, a rectilinear scan of the lumbar spine and the proximal femur using a well-collimated dual photon x-ray (DEXA) source.  Computer processing of the data and comparison to young normals (not age-matched) and to age and sex-matched controls was performed.

FINDINGS:

The T-score (young normal comparison) value of bone mineral density for the L1-4 region is [...] SD which represents [...]% of normal.  

The Z-score (age and sex matched comparison) values of bone mineral density for the L1-4 region is [...] SD which represents [...]% of normal.

The T-score (young normal comparison) bone mineral density for the total proximal right femur is [...] SD, which represents [...]% of normal.  The T-score bone mineral density in the femoral neck is [...] SD, which represents [...]% of normal.  

The Z-score (age and sex matched comparison) bone mineral density for the total proximal femur is [...] SD, which represents [...]% of normal.  The Z-score bone mineral density in the femoral neck is [...] SD, which represents [...]% of normal.

Based on T-score values, the normal range includes to -1.0 SD, the osteopenic range extends to -2.5 SD; the osteoporotic range extends beyond -2.5 SD from the mean g/cm2.

Comparison with the prior DEXA scan:

Lumbar spine BMD changed by [...]%

Proximal femur BMD changed by [...]%

IMPRESSION:

Normal bone mineral density study of the lumbar spine and the proximal femur. 

There are no significant changes since the prior study.

[...] osteopenia of the lumbar spine. 

[...] osteopenia of the proximal right femur. 

There are degenerative changes throughout the lumbar spine that falsely alter bone mineral density. This region is excluded from calculations.

Bone mineral density of lumbar spine is numerically within normal range; however, there are degenerative changes throughout the lumbar spine that may have falsely elevated bone mineral density in this region.

Please note that there are degenerative changes throughout the lumbar spine that may have falsely elevated bone mineral density in this region.

Because of equipment change and updated database, comparison to previously reported BMD is not reliable and therefore not reported

In comparison to the prior bone mineral density there is an insignificant change in the bone mineral density of the lumbar spine by [...]% and an insignificant change in the bone mineral density of the right femur by [...]%.

This one-time bone mineral density examination tells nothing about the rate of mineral loss. To establish the rate of mineral loss and/or to evaluate the effects of medical therapy, a repeat study of the lumbar spine and of the proximal femur in twelve to eighteen months is recommended.

Thank you for referring this patient to the UCLA Nuclear Medicine Clinic
