Dry (selenium) plate electrostatic photography is a common method of mammography. This method makes the micro-density difference clear, which makes small lesions easy to detect and improves the discovery rate of early breast cancer. Breast dry plate photography (ie selenium electrostatic photography) is a multi-layered electrostatic latent image that is left on the surface of the selenium plate by X-ray through the breast tissue, and is imaged by the powder spray to form a macroscopic image, and the diagnosis method is based thereon. . Clinical application of mammography is more extensive.

Basic Information

Specialist classification: Oncology examination classification: X-ray

Applicable gender: whether men and women apply fasting: not fasting

Tips: Check out the need to expose the breasts, so the upper body should wear clothes that are easy to take off. Normal value

Block shadow rules, edge rules, there is no high density of the central area.

Clinical significance

Abnormal results: If the block density is uniform, there is often a fat ring with a high brightness around, indicating a benign mass in the breast; if it is coarse and scattered, the surrounding tissue may be affected by the phenomenon of calcification; Irregular or lobulated, the central zone is dense, and some of the lumps are burr-like at the edges and may be malignant.

Need to check the population: women over the age of childbearing and patients with corresponding symptoms and high-risk groups of breast cancer.

Precautions

Taboo before inspection: no special contraindications.

Requirements for inspection: Checking for relaxation, checking may cause physical and psychological burdens, should be actively faced, and actively cooperate with the inspection. The examination needs to expose the breasts, so the upper body should wear clothes that are easy to take off. When a lump is found, attention should be paid to the presence of abnormal signs such as thickening of adjacent skin, increased blood supply, and increased subcutaneous fat density. At the same time, don't forget to find other lesions on the ipsilateral and contralateral breast. Even if the clinical diagnosis of breast cancer is well defined, mammography should be performed because mammography can help determine the location of the tumor, the extent of tumor infiltration, the presence or absence of multiple cancers, and the contralateral breast. The above information is essential for the correct development of treatment options.

Inspection process

A two-dimensional image of the breast is projected onto the X-ray film by using the physical properties of the X-ray and the different density values ​​of the human breast tissue, and a diagnostic method for observation is performed. Breast dry plate photography (ie selenium electrostatic photography) is a multi-layered electrostatic latent image that is left on the surface of the selenium plate by X-ray through the breast tissue, and is imaged by the powder spray to form a macroscopic image, and the diagnosis method is based thereon. . Clinical application of mammography is more extensive.

Not suitable for the crowd

Inappropriate people: lactating women.

Adverse reactions and risks
