Radiographs are primary tools to rule out etiologies of pain such as masses, fractures, spondylolysis, and spondylolisthesis. Axial imaging such as computed tomography (CT) scans, CT myelograms, and magnetic resonance imaging (MRI) is indicated when other etiologies of back pain or leg pain must be excluded or when spine surgery is being considered. MRI is non invasive and superior for identifying cord disorders, neural tumours, far lateral disks, and allows evaluation of the hydration of the disks and visualization of the marrow of the vertebral bodies. However, there is a high false-positive rate with MRI scans.

BACKGROUND: Mammographic density is a risk factor for breast cancer. Mammographic density and breast magnetic resonance imaging (MRI) volume (MRIV) assess the amount of fibroglandular tissue in the breast. Mammographic density and MRIV can be modulated with hormonal interventions, suggesting that these imaging modalities may be useful as surrogate endpoint biomarkers for breast cancer chemoprevention trials. We evaluated the effect of raloxifene on mammographic density and MRIV in premenopausal women at increased risk for breast cancer.METHODS: Mammograms and MRI were obtained at baseline and after 1 and 2 years of 60 mg raloxifene by mouth daily for 27 premenopausal women. Mammographic percent dense area was calculated using a semiquantitative thresholding technique. T1-weighted spoiled gradient-echo MRI with fat suppression was used to determine breast MRIV using a semiautomatic method. Mean change in mammographic density and median change in MRIV were assessed by the Wilcoxon signed-rank test.RESULTS: No significant change in mammographic density was seen after treatment with raloxifene. Mean change after 1 year was 1% [95% confidence interval (95% CI), -3 to +5] and after 2 years was 1% (95% CI, -2 to +5). MRIV decreased on raloxifene. Median relative change in MRIV after 1 year was -17% (95% CI, -28 to -9; P = 0.0017) and after 2 years was -16% (95% CI, -31 to -4; P = 0.0004).CONCLUSIONS: In high-risk premenopausal women, mammographic density did not change on raloxifene, whereas MRIV significantly declined. Our findings suggest that MRIV is a promising surrogate biomarker in premenopausal women at increased risk for breast cancer and should be investigated further in breast cancer prevention trials.

Make money with x-ray technician job

Did you know the hospital in your community might suffer from a shortage of trained radiographers, more commonly known as x-ray technician?

It's true: the medical field needs more trained x-ray technician now. Demand for various kinds of radiologic technologists, including x-ray techs, is escalating with the aging of the baby-boomer population and rapid advances in diagnostic imaging.

That means career opportunities for graduates of x-ray technician schools are surging at hospitals, physician offices, diagnostic imaging facilities, and other outpatient facilities.
Employment of licensed radiographers, trained at x-ray tech schools, is expected to increase by more than 20 percent through 2012, reports the U.S. Bureau of Labor Statistics.
Salary and benefit packages also should continue to improve as employers seek to retain qualified radiographers, particularly those with specializations in mamography, computed tomography (CT scan), and magnetic resonance imaging (MRI). Today's median salary for x-ray technicians is more than $50,000, according to the American Registry of Radiologic Technicians.
Earn a competitive salary and play a valuable role in the health of your community; attend one of the nation's respected x-ray technician schools and earn your radiographer certificate or degree
