动态增强磁共振成像(dynamic contrast-enhanced magnetic resonance imaging,DCE-MRI)是近年来随着磁共振技术不断发展而产生的一种无创性评价肿瘤血管特性的功能成像方法,已成为肿瘤学及放射学等领域的研究热点,包括肿瘤的良恶性鉴别、血管生成、治疗疗效评价及预后诸方面[1-3]。鼻咽癌(nasopharyngeal carcinoma,NPC)是来源于鼻咽黏膜被覆上皮和黏膜腺体的恶性肿瘤,具有血管依赖性,常用血管内皮标记 Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a non-invasive functional imaging method for evaluating the characteristics of tumor blood vessels, which has become an oncology and radiation. Research hotspots in the fields of science, including the differentiation of benign and malignant tumors, angiogenesis, therapeutic efficacy evaluation, and prognosis [1-3]. Nasopharyngeal carcinoma (NPC) is a malignant tumor derived from the mucosa of the nasopharyngeal mucosa covered with epithelial and mucosal glands.
