X-RAY     DATE: May 29, 2007     FINALIZED     PARNASSUS

PROCEDURES: BONE DENSITY SPINE/HIP (05/29/07 15:20)

BONE DENSITOMETRY REPORT

Lumbar spine and hip DXA (Dual Energy X-ray Absorptiometry)

CLINICAL DATA: 65 y.o. male, r/o osteoporosis.

COMPARISON: None

TECHNIQUE:

On 05/29/2007, a bone mineral density (BMD) measurement was performed of the L1-L4 vertebrae and the proximal femur (total femur, neck, trochanteric and intertrochanteric region) using a Hologic Discovery A series densitometer.  BMD values were determined in gms/cm2 and compared to a young normal reference population (T-score = SDs below or above the young normal mean) as well as to an aged-matched normal reference population (Z-score = SDs below or above the age-matched normal mean).  The reference BMD values for the hip were derived from the NHANES data, for the spine the Hologic reference data were used.  According to the WHO criteria osteoporosis is defined by T-scores, but please note that these are only defined for a Caucasian female 65 years or older.

RESULTS:

BMD Values T-score Z-score

L1-L4 Total 0.997 -0.9 -0.1

Total Femur 0.838 -1.3 -0.8

Femur Neck 0.658 -2.0 -1.0

Positioning, artifacts and morphologic findings: None

IMPRESSION:

The BMD of the lumbar spine is 0.9 standard deviations below that of a normal, young reference population.

The BMD of the proximal femoral neck is 2.0 standard deviations below that of a normal, young reference population.

According to WHO-criteria these findings are consistent with osteopenia.  There is an increased fracture risk.

RECOMMENDATIONS:
Calcium and vitamin D supplements with weight bearing exercise.
Repeat DXA in 2 years.
