Bone Densitometry

Rossmoor Medical Associates has recently upgraded their bone densitometer for measuring bone density.  We have a GE Lunar Prodigy Advance unit.  This unit measures Bone Mineral Content (SMC) in grams and the Bone Mineral Density (BMD) in grams per square centimeter.

The GE Prodigy improved technology detects subtle bone changes in a variety of clinical applications and provides Advanced Hip Assessments and Dual Energy Vertebral Assessments.  Utilizing Direct-digital detector technology, Prodigy delivers rapid scans, near radiographic imaging and dose efficiency three to five times better than existing fan beam systems. 

The Prodigy machine has a comprehensive range of applications.  The machine has the capability of site-specific bone density measurement to include the hips, lumbar spine, and the forearm. Other applications include Dual-energy Vertebral (DVA).  DVA allows clinicians to visualize vertebral deformities for enhanced fracture risk.  Prodigy also has the ability to measure Body Composition.  DXA accurately measures the loss or gain of fat and muscle tissue and provides information that is not available form other methods of assessment.

Bone density measurement is an invaluable aid in diagnosing and managing osteoporosis. It is estimated that at age 50, a woman has nearly a 40% chance of developing an osteoporotic fracture during her remaining lifetime. Bone densitometry can measure changes in bone density and the effect of therapy on bone density, as well as provide an accurate picture of the risk of future fracture. Thanks to the development of 8MD technology, prevention and treatment of osteoporosis is now realistic and possible.

There are many reasons to consider bone density measurement. We have found that although there are patients who may fit the criteria for a "high risk" profile for osteoporosis. (i.e. female, small frame, of Caucasian or Asian descent, post-menopausal decrease in estrogen, prolonged use of steroid medications, hypothyroidism, etc.) we can not always predict the outcome of the test results. The results do not always equate with what you would expect from information in the patient history. The bone densitometer is a fast and accurate approach to determine the presence of osteoporosis, or to more accurately predict who may develop the disease.

BMD testing is easy and safe. The test is simple, safe, noninvasive, and painless-you don't even need to undress. Some common questions about Bone Density Testing are:

If you think you may be pregnant, or are not sure, you should wait to schedule your exam until you are certain. If you have any further questions, please call us at (925) 933-1210 .

An Echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than an x-ray image, and involves no radiation exposure. An echocardiogram helps determine the size of the heart, how the heart valves are working, and how well the heart is pumping.  A trained sonographer performs the test and a physician will interpret the results. There is no special preparation for this test. You will be asked to disrobe from the waist up and lie on an examination table on your back. Electrodes will be place on your chest so an EKG can be done. A gel will be spread on your chest and the sonographer will place the transducer, the instrument that transmits the sound waves, on your ribs near your heart. You will feel slight pressure on your chest from the transducer, and may be asked to roll to your side or change your breathing for parts of the test. The echocardiogram test should be completed within 45 minutes.
