乳腺钼靶钙化征象分类与乳腺良恶性肿瘤诊断的价值

The Value of Mammography in the Classification of Calcification Signs and the Diagnosis of Benign and Malignant Breast Tumors

摘要: 乳腺钼靶钙化征象的分类及其在乳腺良恶性肿瘤诊断中的价值，已成为影像学和临床医学研究的热点。钼靶X线摄影检查作为乳腺癌筛查的主要手段，其在识别和区分乳腺良恶性肿瘤方面的准确率高达90%以上。在钼靶X线上观察到的乳腺钙化现象，虽然多数为良性病变，但其在恶性肿瘤的诊断中也占有重要地位。据统计，大约80%的乳腺良性病变和20%的恶性肿瘤表现为钙化，而乳腺癌患者中有约65%合并有乳腺钙化。本研究通过对比分析乳腺良恶性病变中的微钙化征象，发现其在钙化的数目、密度、密集度、形态及分布特征上存在显著差异。这些差异为乳腺良恶性病变的诊断提供了重要的影像学依据。例如，乳腺癌中的微钙化往往表现为低密度、数目多、密集度高，形态上以细沙样、线形分支样、蠕虫样等为主，而良性病变则多以粗颗粒样钙化为主。在分布上，乳腺癌的微钙化多呈线状或段状分布，而良性病变则多表现为弥漫状分布。进一步的研究还分析了乳腺疾病患者的钼靶X线影像，发现乳腺钙化的性质及其表现特征对于乳腺良恶性病变的鉴别诊断具有显著的临床意义。特别是在微小乳腺癌和导管浸润癌的早期诊断方面，钼靶钙化征象的分类和分析显得尤为重要。因此，深入理解和掌握乳腺钼靶钙化征象的分类及其诊断价值，对于提高乳腺良恶性肿瘤的诊断准确性、促进早期治疗以及改善患者预后具有至关重要的意义。

Abstract: The classification of mammography calcification signs and their value in the diagnosis of benign and malignant breast tumors have become a hot spot in imaging and clinical medical research. As the main means of breast cancer screening, mammography has an accuracy rate of more than 90% in identifying and distinguishing benign and malignant breast tumors. Although most of the mammary calcifications observed on mammography are benign lesions, they also play an important role in the diagnosis of malignant tumors. According to statistics, about 80% of benign breast lesions and 20% of malignant tumors show calcification, while about 65% of breast cancer patients have breast calcification. In this study, we found that there were significant differences in the number, density, intensity, morphology and distribution characteristics of microcalcification in benign and malignant breast lesions. These differences provide an important imaging basis for the diagnosis of benign and malignant breast lesions. For example, microcalcifications in breast cancer tend to be low-density, large in number, and high in intensity, and are mainly fine sand-like, linear-branched, and worm-like, while benign lesions are mostly coarse-grained calcifications. In terms of distribution, the microcalcifications of breast cancer are mostly linear or segmental, while the benign lesions are mostly diffuse. Further studies also analyzed the mammography of patients with breast diseases, and found that the nature and manifestations of breast calcification have significant clinical significance for the differential diagnosis of benign and malignant breast lesions. In particular, in the early diagnosis of microscopic breast cancer and ductal invasive carcinoma, the classification and analysis of mammography calcification signs are particularly important. Therefore, it is of great significance to understand and grasp the classification and diagnostic value of mammography calcification signs to improve the diagnostic accuracy of benign and malignant breast tumors, promote early treatment, and improve the prognosis of patients.
