With the popularity of physical examination and popularization of popular science knowledge, people have to womenThe cognition of the disease has been greatly improved.Among the many womens diseases, there is a very common disease, that is -breast nodule.So, if the physical examination finds the breast nodules, how to understand the BI-RADS classification on the report?
What is the breast nodule
Popularly speaking, the mass that can be felt is called a mammary mass. The campaigns found in the examination are called breast nodules.Most of the breast nodules were found and considers a benign low echo lesion, but there is also a possibility of viciousness. The breast image report and data system (BI-RADS) of the American Radiation Society (BI-RADS) 3 or 4A.
How to check
Most of the breast nodules cannot be determined by the palpation, and it is necessary to use auxiliary examination to assist diagnosis.The most commonly used is ultrasonic examination (including ultrasound angiography), molybdenum target, and nuclear magnetic resonance.
1. Ultrasound
High nature, but the level of ultrasound physicians will affect clinical diagnosis.
How to interpret the ultrasound report?In addition to checking the conclusions on the checklist, doctors usually look at the description of the ultrasound. If the description of a nodule is clear border, morphological rules, and uniform internal echo, the possibility of the nodule is high;The boundary is unclear, the form is irregular, and the vertical and horizontal ratio> 1. There are multiple small calcification points inside, and the vicious possibility cannot be ruled out. It is best to further diagnose biopsy.
2. Molybdenum target
molybdenum target is ultrasound checkA supplement, it is more conducive to the diagnosis of calcification.In the description of molybdenum target inspection, large particles and scattered calcifications are usually benign, while fine granular, clusters of calcification points tend to be malignant.
During the breast census, it is recommended that the female color Doppler ultrasound and molybdenum targets over 40 are recommended.Normal census is not recommended for young women.
3. MRI
This is discovery and diagnosisThe most sensitive method of breast cancer can be 90%to 99%of the sensitivity.It can indicate the boundary, form, size, surrounding infiltration of the nodules.
What is BI-RADS classification
At present, each imaging examination uses the BI-RADS hierarchical evaluation system to help evaluate the diagnosis of breast nodules.The BI-RADS classification method divides the breast lesions to level 0-6. Generally speaking, the higher the level, the greater the possibility of malignant.
BI-RADS Level 0 : It meansEssence
BI-RADS level 1 : negative results, no abnormal lesions were found.
BI-RADS level 2 : Besten benign lesions, which can basically exclude malignant and regular review.
BI-RADS Level 3 : It may be a benign lesion, the malignant rate is generalIt can be checked when there is a clinical need.
BI-RADS level 4 : Suspicious and malignant lesions, the possibilityInspection (CNB), vacuum assisted minimally invasive biopsy (VAB), or surgical biopsy for inspection.
4A : Living tissue inspection is needed, but the possibility of malignancy is lower (
