概括

垂体腺瘤侵入洞穴鼻,显示出类似的血液供应来源. 然而,与洞穴性鼻腔组织相比,塞拉图尔西卡瘤组织的血液流动和微血管性显著增加.

科学领域:

放射学放射学是一门学科.
在瘤学瘤学.
内分泌学在内分泌学.

背景情况:

垂体腺瘤可以侵入洞穴鼻,影响治疗和预后.
了解血液供应分布对于评估瘤行为至关重要.

研究的目的:

为了研究和比较海 pituitary macroadenomas 在状内和那些入侵洞穴鼻腔的血液供应特征.
使用动态对比增强型MRI (DCE-MRI) 进行瘤血管性的详细分析.

主要方法:

追溯分析44名患有 pituitary macroadenomas 和洞穴鼻腔侵袭的患者.
术前动态对比增强型MRI (DCE-MRI) 采集.
基于T2WI冠状图的瘤细分和使用后处理工作站分析时间信号强度曲线.

主要成果:

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
