Description

Magnetic resonance mammary gland coil positioning bracket

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a magnetic resonance mammary gland coil positioning bracket.

Background

Magnetic resonance imaging is used for breast examinations for only more than a decade. Due to the use of special technology and specially-made surface coils with high resolution, the quality of magnetic resonance imaging is greatly improved, small damage can be displayed, the microstructure of the breast can be displayed, and the diagnosis of breast diseases has certain value, so that the reports of the magnetic resonance imaging for detecting the breast diseases are gradually increased in recent years. Magnetic resonance imaging is used to diagnose breast disease mainly based on morphological changes, signal characteristics and enhanced dynamic changes of lesions. The magnetic resonance examination can be carried out on breast cyst, intramammary hemorrhage or hematoma, breast diseases in lactation period of pregnancy, breast prosthesis condition observation and the like. The main points of the identification of benign and malignant lesions of the mammary gland magnetic resonance image are as follows: the benign lesion focus edge is smooth and clear, the signal intensity is generally similar to that of the surrounding catheter, and the signal intensity of the hyperplasia of mammary glands is slightly lower than that of the adjacent catheter; malignant lesions have lower signs than adjacent ducts, are indistinct and irregular at the margins of lesions, can infiltrate into the surroundings, and are often adherent to the skin. If the enhancement of the signal is dynamically observed after the magnetic resonance enhancement, i.e. the intravenous injection of paramagnetic contrast medium, the method can provide clearer data for the differential diagnosis of good and malignant lesions, i.e. malignant tumors are almost always enhanced more quickly and obviously than benign tumors. The method can be used for easily distinguishing benign or malignant breast lumps, breast cancer recurrence, scars after breast surgery and the like. In addition, the magnetic resonance examination is more superior for patients with implanted surgical prosthesis, and the breast prosthesis can be accurately judged whether the breast prosthesis has the changes of rupture, leakage and the like. Compared with other examination methods, the examination of breast diseases by magnetic resonance imaging is still in the "infant" stage, and a lot of potential remains to be developed. The magnetic resonance examination has obvious advantages in some aspects, such as effective identification of good and malignant diseases of mammary gland, no radiation injury, three-dimensional imaging, and magnetic resonance display for patients who cannot be examined by molybdenum target X-ray radiography, such as breast root lesion, axillary lesion, and especially when the lesion is close to the deep chest wall of the breast.

The existing mammary gland magnetic resonance examination needs to use a positioning bracket for auxiliary detection, and the existing magnetic resonance mammary gland coil positioning bracket has a simple structure and a single function.
