The CoreScan™ application offers you the following benefits:
To effectively assess obesity and metabolic diseases that affect millions of people, you need credible measurements of visceral fat — reproducible results from a validated method. Designed to do just that, CoreScan™ gives you a fast and easy way to accurately quantify visceral fat.
The CoreScan™ is an application to quantify visceral fat by using low-dosage, dual energy absorptiometry (DXA) technology. It can help you predict patient disease risk, assess and manage treatment approaches, and add important contributions to the body of published research — all at a lower dose than conventional visceral fat measurement techniques.
The CoreScan™ application features an exclusive algorithm that uses data from the total body measurement of the patient using a DXA scan, and has been validated in clinical trials with CT technology. CoreScan™ has proven to have a high degree of correlation with CT technology across genders and wide range of BMI’s.
Successful research and treatment begins with credible data: reproducible results from a validated method. CoreScan™ software sets a standard for visceral fat quantification. It can help you predict cardio-metabolic risk, assess treatment approaches, and add important contributions to the body of published research.
The CoreScan™ application puts accurate visceral fat quantification within reach — opening new possibilities for clinicians and researchers. It provides a fast and easy method, whether assessing individual patients or performing large clinical studies — and at a lower dose of radiation than conventional CT and MR technology.
Why It’s Done
Used by professional athletes, personal trainers, and physicians, the Lunar iDXA CoreScan™ body composition scanner demonstrates unprecedented accuracy and precision body measurement in 14 different metrics to effectively assess obesity and metabolic diseases that affect millions of people, you need credible measurements of visceral fat — reproducible results from a validated method. Designed to do just that, CoreScan™ gives you a fast and easy way to accurately quantify visceral fat.
Accurate measurement of body composition provides valuable information for assessing, monitoring and treating a variety of diseases and disorders. Most people are used to stepping on a scale before every visit to a doctor’s examining room. But monitoring patients’ weight – while helpful – is at best a crude and imprecise way to assess their health. Today’s body composition measurement tools provide far more complete and precise information that can help support diagnoses and guide treatment. They can even help athletes make decisions on the training regimens they use to achieve the best performance. Body composition measurement with dual-energy X-ray absorptiometry (DXA) can look beyond weight and the traditional body mass index (BMI) to determine body fat distribution – an important risk factor in a variety of serious diseases. More broadly speaking, information from DXA exams can prove valuable in conditions, such as:
- Anorexia Nervosa
- Cystic Fibrosis
- Wasting Syndrome (caused by HIV/AIDS)
- Chronic renal failure
In all these cases, body composition measurement contributes to a thorough patient evaluation and helps physicians monitor the effects of therapy, diet or exercise. Body composition scans with DXA provide precise and accurate data on bone and tissue composition, including bone mineral density (BMD), lean tissue mass, and fat tissue mass. They provide both total body data and regional results (trunk, arms, legs, pelvis and android/gynoid regions). The measurements are fast and noninvasive.
The value of body composition measurement is not limited to treating illnesses – it can help some of the healthiest . Most athletes benefit from a lean body composition (low body fat percentage). In general, body fat beyond the amount needed for good health reduces efficiency. Athletes can achieve the body composition they desire through training and a proper diet. Experts say the key is to track how much body fat athletes lose instead of relying on the bathroom scale. Height/weight tables based on BMI do not distinguish muscle from fat and so are not useful for high performing athletics. A recent study in the United States by Oates et al. suggest that “DXA values may be more fundamental and less affected by anthropometric variables, or at least more precisely determined than the values for the other techniques”.11 For highly trained athletes, even a small change in body composition can significantly affect performance. Body composition monitoring provides valuable information that athletes and their trainers can use to adjust diet and training regimens. Body composition measurement helps establish a starting point and a target, helping any athlete to pursue a specific goal.
DXA stands for Dual-Energy X-ray Absorptiometry. It is a measurement method that uses the differences in the absorption of high energy and low energy X-ray photons by different elements in a body to quantify the amount of bone and soft tissue in the body. For example, certain elements in bone minerals (e.g. calcium) will absorb more low-energy X-rays than the elements in soft tissue, enabling a precise and accurate estimate of bone mineral density (BMD). By using relevant algorithms, we can also use the same measured data to determine body composition due to the different density and composition of fat and lean tissue. Although the test relies on radioactive tracers to produce the images, these tracers produce little radiation exposure — less than a CT scan.
The detectors in GE Lunar products perform a crucial task – count each individual X-ray photon and classify it as either “low-energy” or “high-energy.” Lunar iDXA detectors use solid-state crystals (Cadmium Telluride or CdTe) that absorb the X-ray energy and result in the immediate release of electrons from their atoms (i.e. direct conversion). An applied voltage pushes the electrons out of the crystal, effectively creating a current pulse whose magnitude is proportional to the X-ray energy. Sensitive, low-noise amplifiers boost the signal so that counting electronics can perform the final identification as low or high energy.
Additional safety features:
A unique “K-edge filter” that absorbs the X-rays in the middle energy range and protects the patient against unnecessary exposure.
Photon Counting Detector
Dose-efficient photon counting detector technology that simultaneously counts low and high energy X-rays photons resulting in lower dosage to the patient and faster and efficient scans.
Unique feature exclusive to GE Healthcare bone densitometry systems that identifies bone regions after each transverse sweep to estimate where to begin exposing the patient to X-rays on the subsequent sweep, thereby reducing the scan time and the dose to the patient.
You’ll lie still on a table while an armlike device supporting a tracer-sensitive camera passes back and forth over your body. The scan itself can take up to an hour. The procedure is painless.
You typically don’t need to restrict your diet or restrict activities before a bone scan. Let your health care provider know if you’ve taken a medicine containing bismuth, such as Pepto-Bismol, or if you’ve had an X-ray test using barium contrast material within the past four days. Barium and bismuth can interfere with bone scan results.
Wear loose clothing and leave jewelry at home. You might be asked to wear a gown for the scan.
Bone scans aren’t usually performed on pregnant women or nursing mothers because of concerns about radiation exposure to the baby. Tell your health care provider if you’re pregnant — or think you might be pregnant — or if you’re nursing.
