Breast MRI has many advantages, but due to check the prices of more expensive, we can not as a routine examination of breast diseases, just as the breast X ray and B-ultrasonic examination of the auxiliary projects, and the following conditions need to be breast MRI :
1. X line and the B-ultrasonic examination of the lesion can not be confirmed. When the breast X ray or a B-test results ambiguous and difficult to diagnosis, the use of MRI can provide more information for differential diagnosis to provide strong evidence.
2. Found in occult breast cancer. Some breast cancer showed only axillary lymph nodes, clinical examination and X-ray photography can not be found in lesions, this time by doing breast MRI can often be found in the smaller primary tumors.
3. Has done to expand the breast plastic surgery women. Breast augmentation surgery prosthesis into the leak occur the possibility of rupture, according to statistics for varying periods, an average of 12 years of foreign and domestic prosthesis an average of 8 years. About half of the patients with no obvious clinical symptoms, therefore prostheses were placed in a longer time, it is recommended for its line of magnetic resonance examination, early detection can often implant rupture, and timely treatment. Done breast augmentation surgery for breast, X-ray examination when the need to pressure the breast implant causing secondary rupture and the danger of proliferation of water gel, another implant prosthesis because of obstruction, X-ray examination showed lesions difficult. The MRI did not exist these problems, it can effectively show lesions, and diagnosis. Therefore, post-operative palpation of suspicious breast mass, MRI should be OK.
4. Going to do breast-conserving surgery patients. The significance of breast-conserving therapy: In the complete removal of cancer lesions while preserving a satisfactory breast shape. The international community nearly 30 years, a number of studies have shown that the strict selection of cases, breast-conserving treatment effect of long-term survival is equivalent to the whole breast removed. But the regular breast X-ray photography and the B-tend to underestimate the extent of the tumor, to multi-center and multi-site lesions showed incomplete, after doing MRI may also be in other parts of the breast lesions found in the other. For such patients should be done mastectomy rather than breast-conserving surgery. The United States, studies have shown that about 40% of the patients who do breast-conserving surgery because it underestimated the extent of the operation, leading to local recurrence. Thus, for breast X-ray photography of breast cancer patients with suspected or diagnosed by needle biopsy of breast cancer patients who wish to breast-conserving therapy, it is recommended to do breast MRI prior to surgery.
5. High-risk population screening. Use of MRI to screen high-risk groups than any other imaging examination of suspicious lesions more easily can be achieved early diagnosis and early treatment. Breast cancer high-risk population is defined as: past history of breast cancer; relatives with breast cancer history; a BRCA gene mutation; had lines breast biopsy, confirmed by pathology for non-atypical hyperplasia; lobular carcinoma in situ; radial scar; Zengyin lymphoma line cape radiotherapy patients.
6. Right response to neoadjuvant chemotherapy for breast cancer evaluation. Traditional post-operative adjuvant chemotherapy, due to unpredictable efficacy, there is considerable blindness, can not achieve therapeutic purposes. Neo-adjuvant chemotherapy before surgery, you can observe the lesion response to treatment to determine treatment options are valid. Chemical treatment can lead to breast fibrosis, reducing the clinical palpation and breast X-ray sensitivity. MRI contrast-enhanced lesion in accordance with the reduction to determine the response to chemotherapy, this approach to the examination after chemotherapy response to high sensitivity.
Breast MRI has many advantages, is a traditional mammography X-ray photography and effective auxiliary examination method, which can significantly increase breast diseases, especially breast cancer and early detection rate of occult breast cancer. But in China, breast MRI has not been universal, I believe that with the magnetic resonance imaging equipment and advances in technology, applied research in-depth, comprehensive treatment in breast MRI the important role and value will be more fully and comprehensive knowledge.
