当代医疗包括预防、诊断和治疗三大要素。计算机科学的发展给医疗器械以及医疗诊断和医疗带来了新的革新。计算机断层扫描（CT）、磁共振（MR）、超声和放射疗法都源自这项技术的范围。CT是一种扫描技术，在人体器官成像系统中很有用。结合X线和计算机工程，可大大提高诊治水平。目前，它已成为一种常规的医生告知病情患者并提出处理建议，同时管理（松德兰德固化过程的副作用1999）。 在乳腺癌的诊断成像技术的应用，在临床检查中最常用的方法是乳腺X射线、超声、MRI、核医学检查。所有这些检查方法中，乳腺X射线具有最大的优势，成为诊断乳腺癌的首选，而如今是联合超声。MRI和PET-CT检查是对乳腺癌的临床分期有效，尤其用于高危患者的病变检测（井上M 2003）。   常见的乳房成像方法包括乳房X光摄影、乳腺超声、CT和MRI等。在辐射成像方法中，本文分析了如何正确选择自己的成像方法。乳房X光摄影有助于乳房的早期诊断，已成为乳房影像诊断的首选。乳腺超声可用于检查盲点和检测软组织分辨率。乳房检查无辐射，青少年或孕妇、哺乳期妇女首选检查乳腺病变的方法。CT一般是作为补充乳腺X线及超声检查。CT对乳腺致密病灶、腋尾及乳腺内淋巴结内癌的诊断具有无可比拟的识别能力。MRI检查有三个明显的优点：（1）对乳腺致密化及乳腺癌局部复发有较高的敏感性。2）断层是三维成像，使病变定位更准确。3）当多中心、多灶性病变发现侵犯乳腺组织时，它是优越的。

The contemporary medical treatment consists of three key elements prevention, diagnostics and therapy. The development of computer science brings about new renovations in medical device as well as medical diagnosis and medical treatment. Computed Tomography(CT), magnetic resonance(MR), ultrasound and radiation therapy all stem from the range of this technology. CT is a scanning technique which is useful in imaging organ systems in the body. When combined with X-rays and computer engineering, the diagnosis and treatment can be greatly promoted. Currently, it has become a routine that doctors informs the patients of their condition and put forward the treatment suggestions, meanwhile manage the cure procedure and side effects(Zonderland 1999). As to the application of imaging techniques in the diagnosis of breast cancer, the most common methods in clinical examination are mammographic X-ray, ultrasound, MRI and nuclear medicine examinations. Among all these examination methods, mammographic X-ray has the largest advantage and becomes the first choice for breast cancer imaging, which nowadays is combined with ultrasound. MRI and PET-CT examination are effective in categorizing the clinical stages of breast cancer and are especially used in high-risk patients with lesion detection(Inoue M 2003).   Common breast imaging methods include breast X-ray mammography, breast ultrasound, CT and MRI and so on. Among the radiation imaging methods, this passage analyzes how to correctly choose their own imaging. Breast X-ray mammography is good for an early diagnosis of breast, which has become the first choice for the diagnosis of breast imaging. Breast ultrasound can be used in examination of blind spots as well as detect soft tissue resolution. Breast examination without radiation, teenagers or pregnant, lactating women preferred method of examination of breast lesions. CT is generally used as supplement for mammographic X-ray and ultrasound examination. CT has incomparable identification of the cancer inside dense breast lesions and axillary tail and internal mammary lymph nodes. MRI examination has three evident advantages: 1)It has higher sensitivity for dense breast and local recurrence of breast cancer. 2)The fault is three-dimensional imaged, enabling more accurate lesion localization. 3)It is superior when it comes to multi-center, multifocal lesions detected violations of the breast tissue.
