项目摘要
We have developed target liposome for malignant brain tumor. This liposome contained MR enhanced materials which identify the distribution area of chemotherapy drugs under the MR imaging.A noninvasive method to evaluate intracranial pressure (ICP) and brain tissue compliance based on magnetic resonance (MR) imaging was proposed.Brain circulations, blood and cerebrospinal fluid (CSF) flows, was devised. The input for the inverse analysis was the CSF flow rate obtained by phase contrast MR velocity imaging, whereas the estimation function was the square error of the estimated arterial blood flow rate. Experiments using a brain-circulation-mimicking phantom followed by numerical simulations confirmed that the proposed technique yielded relative indices of the compliance and pressure. Studies on 25 healthy (22-63 years old) and 9 patient (27-69 years old) volunteers revealed that the healthy and patient groups distributed in significantly different regions in a two-dimensional space formed space formed by the indices of tissue compliance and intracranial pressure, demonstrating the feasibility and viability of the proposed technique for classifying the statuses of the intracranial biomechanical properties of the subjects.
我们开发了治疗恶性脑肿瘤的靶向脂质体。该脂质体含有磁共振增强物质,可识别化疗药物在磁共振成像下的分布区域。提出了一种基于磁共振成像(MR)的无创颅内压(ICP)和脑组织顺应性评估方法。大脑循环,血液和脑脊液(CSF)的流动,被设计出来。反向分析的输入是通过相衬MR速度成像获得的脑脊液流量,而估计函数是估计动脉血流速率的平方误差。模拟脑循环的实验和数值模拟证实了所提出的方法可以得到相应的顺应性和压力指标。对25名健康志愿者(22-63岁)和9名患者志愿者(27-69岁)的研究表明,在由组织顺应性和颅内压指标构成的二维空间中,健康组和患者组分布在明显不同的区域,证明了所提出的技术对被试颅内生物力学性能状态进行分类的可行性和可行性。
