Molybdenum target photography is a soft X-ray, its dose is very weak, the impact on the patient is negligible, it is basically harmless, used to diagnose early breast cancer. The patient is placed or seated, the film is placed under the breast, and the X-ray is projected from the inside to the outside with a 45'. The advantage of this position is that the posterior interstitial space can be fully included in the slice, so that the mammary gland tail mass, the accessory breast and the axillary lymph nodes are not easily missed.

Basic Information

Specialist classification: Oncology examination classification: X-ray

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

Tips: Check your relaxation, check may cause physical and psychological burdens, you should face it positively, 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. Normal value

There is no lumps in the double breasts, no abnormal calcification and structural distortion, no shrinkage of the double nipples, no thickening of the areola skin, and clear subcutaneous fat layer.

Clinical significance

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.

Precautions

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

Medial oblique position (MLO): The patient is placed in a sitting or sitting position, placing the film under the breast, and the X-ray is projected from the inside to the outside at 45'. The advantage of this position is that the posterior interstitial space can be fully included in the slice, so that the mammary gland tail mass, the accessory breast and the axillary lymph nodes are not easily missed.

The axial position is also called the head and foot position (CC): take the standing position or sitting position, flatten the breast on the dark squat bracket (note that the nipple is tangential), and the X-ray illuminates vertically from above.

Not suitable for the crowd

Inappropriate people: lactating women.

Adverse reactions and risks

Nothing.
