\"Scopul<\/a><\/p>\n

The purpose of the medical tests<\/strong><\/span> is to determine whether a person suffers from osteoporosis, has low bone density and an increased osteoporosis risk, is menopausal and\/or has hormonal deficiencies, or an underlying deficiency causing the exacerbation of the bone mass loss.<\/p>\n

Tests may be performed to assess the bone density loss, the bone health following a fracture or to monitor the efficiency of the osteoporosis treatment. The imaging diagnosis \u2013 a paraclinical investigation \u2013 is used to perform osteodensitometry<\/strong><\/span>, the main osteoporosis diagnosis test.<\/p>\n

Paraclinical investigations:<\/strong><\/span><\/p>\n

Normal Thoracic and\/or Lumbar Spine Radiography<\/strong><\/span> (front and lateral view), which may suggest osteoporosis if it highlights an accentuated demineralization at the level of the scanned segments (in which case DEXA<\/strong><\/span> is further performed to confirm the diagnosis<\/strong><\/span>) sor may indicate an osteoporosis diagnosis if it shows vertebral subsidence in the anterior region of the vertebrae (cuneiform subsidence<\/strong><\/span>).<\/p>\n

The Bone Mineral Density Test (BMD)<\/strong><\/span> ) is the main osteoporosis and low bone mass identification test. One of the preferred and most accurate BMD methods is the dual-energy x-ray absorptiometry (DXA or DEXA). This method uses low intensity X-rays to assess the bone density of the hip and\/or of the spine. The BMD value generally is compared to the maximum young adult bone mass value. A BMD value with a standard deviation of one unit below the BMD value of the young adult is regarded as normal. In the case of osteopenia, BMD ranges between -1 and -2.5 standard deviations below the young adult BMD index, while in the case of osteoporosis the BMD values are below -2.5.<\/p>\n

Several medical organizations have published osteoporosis screening<\/strong><\/span>, guidelines, including the US Preventive Services Task Force. They recommend DXA for the screening of all women above the age of 65 and of women aged between 60 and 64 with fracture risks. The National Osteoporosis Foundation also recommends the screening of men aged above 70, of women aged above 65 and of the middle aged adults falling under the high risk category.<\/p>\n

Medical service providers can also use a new instrument, called FRAX<\/strong><\/span>, , to more accurately assess the hip, wrist, shoulder or spine fracture risk after the age of 40. Available both online and in hardcopy, the calculator, drafted by the World Health Organization (WHO), takes into account the measured bone density value and other 9 risk factors. The FRAX algorithm assesses the absolute fracture risk. NOF has adapted this algorithm for the USA, and it has been included in the Clinical Guidelines as of February 2008.<\/p>\n

Other imaging diagnosis scans that can be performed to measure BDM and identify osteoporosis include the CT scan (computed tomography<\/strong><\/span>a) and ultrasounds<\/strong><\/span>. A general screening test, called \u201cbody composition analysis\u201d, calculates the body mass by assessing the muscle mass, the fat mass, the bone mass and the extracellular water. There are a few different methods to calculate the body composition, including by means of specialized instruments. If the body composition analysis is performed and monitored yearly, it can help identify bone mass losses.<\/p>\n
