A 1 cm calcified lesion may be either orthotopic or oblique, depending on the need for the test. Whether it is orthostatic or oblique, the patient can judge according to the results of the report card. 1. Orthostatic: On orthostatic radiographs, the nipple is used as the demarcation line, and lesions on the outside and inside of the breast are mainly observed. Mammography is particularly sensitive to calcified foci of the breast, which are mainly manifested as translucent “white dots” on the radiographs; “white dots” located in the upper part of the breast are lateral breast foci, and “white dots” located in the lower part are medial breast foci. The “white dot” in the upper part of the breast is the lateral breast lesion, and the “white dot” in the lower part is the medial breast lesion. 2. Oblique position: On oblique radiographs, the pectoralis major muscle and lymph nodes can be shown, and the lesions above and below the breast are mainly observed with the nipple demarcation line. If the 1cm calcified foci are located above or below the breast, they are found by oblique position film, from which you can understand the location of the foci and make a preliminary judgment of benign or malignant. Whether the molybdenum target is in the orthogonal or oblique position depends on the location of the lesion and the need for examination, and is mainly decided by the physician, who is recommended to visit a regular hospital and conduct the appropriate examination under the guidance of the doctor.
