Dual-energy x-ray absorptiometry DEXA is a technique used to aid in the diagnosis of osteopenia and osteoporosis. Radiographic features. Values are calculated for the lumbar vertebrae and femur preferentially, and if one of those sites is not suitable e.g. artifact, patient mobility, or if there is a history of hyperparathyroidism, the forearm can be used 1. DEXA scans provide a unique three-compartment model for the most accurate and precise segmented analysis of body fat percentage and lean tissue arms, legs, trunk and total body, visceral fat quantification in the abdominal region, and bone density scoring. Khoury and Szalay 5 noted that the lateral distal femoral DEXA scan could be performed on patients who could not be scanned at hip and spine due to spinal instrumentation, scoliosis, hip. DEXA Scan for Dual Sites at Femur and Spine. Bone Densitometry or Dual-energy X-ray absorptiometry is a means of measuring bone mineral density. Two X-ray beams, with different energy levels, are aimed at the patient's bones. When soft tissue absorption is subtracted out, the bone mineral density can be determined from the absorption of each beam by bone.
I just got a second DEXA scan- I posted results elsewhere. But when I was there, the technician commented that my hips are "normal" as in not even osteopenic. I. Bone density scans for osteoporosis. Several technologies can assess bone density, but the most common is known as dual energy x-ray absorptiometry DEXA. For this procedure, a machine sends x-rays through bones in order to calculate bone density. The process is quick, taking only five minutes. And it's simple: you lie on a table while a scanner passes over your body. While this technology.
ysis, including areas to scan and detection of artifacts that should be excluded from the analy - sis and noted in the report because they can necessitate additional imaging; and interpretation of results. I had a dexa scan, my t-score was a -0.3 for my lumbar spine L1-L2, and my femoral necks tscore was -0.7. What does this mean for me. Can you send me some information on. Auch innerhalb des proximalen Femurs kann es große Dichteunterschiede geben, so dass in Kontrollmessungen stets nur die gleichen Areale verglichen werden dürfen. Der einzige Nachteil der DXA-Messung ist die integrale Messung des zu untersuchenden Skelettareals. of the scan field. In fan beam systems the data are acquired in three sweeps, starting at the right of the patient and moving from the top to the foot, back over the midline and finally completing the left sweep. There is no operator intervention. In pencil beam systems the scan may be stopped when the scanner arm has cleared the patient’ feet. Single Energy Femur Scan — AFF assessment. Lumbar Spine.

DEXA scans provide a unique three compartment model for the most accurate and precise segmented analysis of body fat percentage and lean tissue arms, legs, trunk and total body, visceral fat quantification in the abdominal region, and bone density scoring. 26.05.2012 · Patients who take osteoporosis medication should have their bone mineral density checked regularly to retain approval of insurance coverage in Korea. In this situation, we can use the films for BMD measured by DEXA as a screening tool for cortical thickening at the subtrochanteric area without additional femur radiographs. As noted above, insufficiency fractures can develop bilaterally. BMD. CONCLUSIONS: Our measurement technique provides a reproducible measurement of HUs within the proximal femur HUs on CT colonoscopy. Hounsfield units of the proximal femur based on this technique can predict low BMD. These CT scans are frequently performed before initial DEXA scans are done and therefore may lead to earlier recognition of low BMD.
