How to correctly select breast imaging examination

With the development of science and technology and the improvement of people's living standards, people pay more and more attention to their own health. Breast diseases are common and frequently-occurring diseases in women, and more than half of them are breast tumors. The common imaging examination methods of breast mainly include mammography, mammography, CT, MRI and infrared ray. In the face of numerous image examination methods, how to correctly choose the image examination that suits you. 1. Mammary X-ray molybdenum target can make early diagnosis of breast cancer and has become the first choice of imaging examination for the diagnosis of breast diseases. It is mainly used for screening breast diseases in women over 50 years old. Disadvantages are: ionizing radiation, low resolution for dense breast (most young and middle-aged). Second, breast color ultrasound breast ultrasound examination has no blind spot, good resolution for soft tissue, and can find small lesions of several millimeters. Breast examination is non-radioactive, which is the first choice for breast lesions of teenagers or pregnant and lactating women. The disadvantage is that the accuracy of its diagnosis depends largely on the equipment used and the personal experience of the examining doctor. Thirdly, breast CTCT is generally used as a supplementary examination for mammography and ultrasound examination. It is superior to X-ray molybdenum target in finding dense breast lesions, abnormal changes of chest wall, breast tail lesions, axillary and internal mammary lymph node enlargement and so on. Disadvantages are: the radiation dose of CT examination is higher than that of X-ray molybdenum target, the examination cost is high, and the accuracy of cystic and solid lesions is not as good as that of ultrasound. Fourth, breast MRI Breast MRI examination is an important supplementary examination of mammography and ultrasound examination. The advantages of breast MRI examination are: 1, which is highly sensitive to the X-ray evaluation of dense breast and local recurrence after breast cancer surgery. 2. The cross section can be imaged in any three dimensions, which can make the focus position more accurate. 3. The detection of multi-center and multi-focus lesions and the degree of invasion to the surrounding tissues of breast are better than other examination methods. Disadvantages: 1, insensitive to microcalcification. 2.MRI examination is relatively complicated and takes a long time, and sometimes it is affected by respiratory motion artifacts. 3. MRI findings of benign and malignant lesions overlap to some extent, so lesions with atypical MRI findings cannot replace breast biopsy. Five: infrared examination infrared examination mainly shows the blood supply of the lesion and reflects the hemoglobin content of the lesion. X-ray examination mainly reflects the change of tissue density, which is more direct. For some lesions with poor blood supply, infrared examination will miss the diagnosis. At present, infrared detection is not considered as sensitive as X-ray detection. (Wen Meiru, Imaging Department)
