Mammography MR vs X-ray
Read on:-
Hi Folks,
The American Cancer Society guidelines Published in the March/April 2007 available at CA: A Cancer Journal of Clinicians specifies that breast MRI screening should only be used with certain groups of high-risk women, such as BRCA mutation carriers and those with a family history of breast cancer. The guidelines do not recommend MR for women at average risk, those with very dense breasts, or those who already have had breast cancer, including ductal carcinoma in situ (DCIS). The ACS Breast Cancer Advisory Group said there is not enough evidence to support MR in this population because of the modality's tendency toward false-positive results.
The ACS also says that breast MRI should be used with conventional mammography as part of an annual screening regimen in certain groups of women.
There is no organized breast cancer screening program in India . Screening mammography needs extensive quality assurance and controls at various levels, which is lacking in India. It is only since the last few years that AERB(India) has made it mandatory to have all mammography units to be prototype approved!
None of the professional organizations that advocate Screening mammography support sonography for screening like American College of Radiology, & FDA.
There are anecdotal reports of breast sonography picking up additional cancers not detected by mammography, and such statements/ claims about the effectiveness of breast sonography - breast screening - are not supported by the medical literature. While anecdotal evidence supports the effectiveness of finding additional cancers by breast sonography, clinical studies have failed to support such claims!
All alternative breast imaging modalities are insufficient for detecting cancer and are not a viable replacement for biopsy, according to a report(2006)released by the Agency for Healthcare Research and Quality (AHRQ). AHRQ is a division of the U.S. Department of Health and Human Services.
Each of the four (non invasive) tests -- magnetic resonance imaging, ultra sonography, PET, and scinti mammography -- would miss a significant number of cases of cancer, for women who receive abnormal findings from a mammogram or physical exam.
All four tests would miss between 4% to 9% of cancers among women with an abnormal mammogram & biopsy remained the most effective technique for revealing any potential for cancer.
