Overall sensitivity for whole-body and PET/CT was 96% and 93% respectively, while specificity was 87% and 88% respectively.
Conclusions
The study showed that both methods are relevant for detecting metastases in breast cancer patients, but also showed that the method chosen should be appropriate to the type of tumor which may be suspected based upon the laboratory and clinical findings. While the study found that both 1.5- and 3-tesla MRI scanning were feasible for the purpose of finding metastases, the team discovered that there is still much work to be done on refining the methods used for 3-tesla scanning. This could lead to further improvements in the results yielded by this method.
Breast gamma imaging spots DCIS better than mammo, MR
Introduction
Breast-specific gamma imaging (BSGI) is a functional study which is unaffected by dense tissue, implants or architectural distortion in the breast. The aim of the study was to assess the effectiveness of this method in detecting ductal carcinoma in situ (DCIS) in comparison to mammography and MRI methods (Pal, 2007).
Methods
22 women were selected for the study based on the presence of DCIS which had been confirmed through biopsy. The study did not take into account family history, genetic predisposition or breast density. BGSI was conducted both before biopsy, to assess indeterminate findings, and after biopsy, to determine foci and extent of disease. BGSI was conducted after injection of 25-30 mCi of technetium 99m-sestamibi, and results were measured by radio-tracer uptake on a five point scale, with 1 being normal, and 5 being abnormal, with marked focal...
1. Screening Mammography Mammography plays a central part in early detection of breast cancers because it can show changes in the breast up to two years before a patient or physician can feel them. Current guidelines recommend a screening mammography every year for women, beginning at age 40. Research has shown that annual mammograms lead to early detection of breast cancers, when they are most curable and breast-conservation therapies are available (Mammography). 2.
D. (http://www.cancernews.com/data/Article/210.asp). The created a need to research and develop a better method of mammography, which lead to the development of the new digital machine. What is digital mammography? Conventional film screen mammography uses low energy x-rays that pass through a compressed breast during a mammography examination. The exiting x-rays are absorbed by film (x-ray film) which is then developed into a mammography image that can be held and looked at by the
Missed Breast Carcinomas Mammography is a particular type of imaging which use an x-ray system, which has a low-dose for the purpose of detecting breast cancer at a very early stage. But even with the help of Mammography, in 10-30% cases of breast cancers would be missed. By way of this paper an attempt has been made to understand the factors, which cause for missed breast cancers, and discuss ways to
Dr. Robb-Nicholson's data best supports the scenario that more incidents of breast cancer will be discovered due to the reduced number of screenings that the new guidelines suggest. According to the numbers she gives, the mortality rate for breast cancer decreases every year and this decrease can be attributed to the previous screening guidelines. She writes that the USPSTF has based the new guidelines on statistics rather than clinical data
Radiology and Cyberspace The creation of 'cyberspace,' or the sharing of information through email, on the Internet and on websites, has had a profound impact on nearly every field of human endeavor. Medical science, and particularly Radiology, has been particularly affected and enhanced by new technology. Radiology, by its very nature, has always been a leader in the use of emerging technology in the medical field. Now, new technology developed during
As a woman enters her geriatric years, many unique problems are also faced. Her post-menopausal period leaves a woman with increased risk of osteoporosis, and hormone-replacement therapy may need to be considered or dismissed depending upon the needs and wellness of the individual women. Additionally, increased risk for obesity begins nearly at the adolescent period, when women's hormone loads change and often activity of childhood decreases. The incidence of
