Clustered indeterminate calcifications of the breast are usually visualized by X-ray or CT. MRI is more of an adjunct to CT, and MRI is better at visualizing soft tissues. Usually, when the clustered calcification of breast cannot be determined as breast cancer, the patient can do the nuclear magnetic examination to make a clear diagnosis, and it is generally recommended that the patient do the ultrasound examination and molybdenum target examination first, and if there is still a big doubt about the nature of the breast calcification after the examination, then the patient can do the nuclear magnetic examination in accordance with the doctor’s prescription. At present, MRI is not the first choice for breast examination. It is usually done when it is difficult to confirm the diagnosis with other tests, and if breast cancer is diagnosed and breast-conserving tests are needed, then MRI can be done to check the lesions. Patients do not need to worry too much when they find clusters of indeterminate calcifications in the breast, which are not necessarily caused by breast cancer, but may also be benign diseases of the breast. Patients are advised to go to regular hospitals and choose the appropriate examination method under the guidance of doctors.
