Abstract

Diferents studies have shown a possible association of neuroimaging as a predictor of intratumoral consistency, an important factor during surgery. To identify the correlation between the consistency of intracranial meningiomas and the image of the T2 sequence of magnetic resonance imaging. Using the PRISMA methodology, a search for clinical studies was carried out in the PubMed, Scielo, Medline and Cochrane databases; descriptors: “consistency”, “meningioma”, “MRI” and “prediction”. Twelve articles were found, with seven remaining after the inclusion criteria: articles written in English and published in the last ten years. The T2-weighted magnetic resonance sequence showed highest degree of correlation in the studies discussed, where T2 hyperintensity of soft tumors may be related to a higher water content, while T2 hypointensity for hard tumors may be due to the greater collagen and calcium content. Most studies allow an association to be established between the soft consistency of the tumor and signal hyperintensity in the T2 sequence of magnetic resonance imaging, with the consistency of the tumor being important, as the surgical difficulty and time depend on it. The hyperintensity of the lesion in T2 was associated with the soft consistency of the tumor, seen during the operation, whereas hypointense meningioma in T2 is associated with firm consistency.

颅内脑膜瘤磁共振成像(MRI) T2信号强度与一致性的关系综述
不同的研究表明,神经影像学可能与肿瘤内一致性的预测有关,这是手术中的一个重要因素。目的探讨颅内脑膜瘤的一致性与磁共振成像T2序列图像的相关性。使用PRISMA方法,在PubMed、Scielo、Medline和Cochrane数据库中搜索临床研究;描述词:“一致性”、“脑膜瘤”、“MRI”和“预测”。共发现12篇文章,其中7篇符合纳入标准:用英文撰写的文章,发表于最近10年。在讨论的研究中,T2加权磁共振序列的相关性最高,软质肿瘤的T2高强度可能与较高的水分含量有关,而硬质肿瘤的T2低强度可能与较高的胶原和钙含量有关。大多数研究认为肿瘤的软一致性与磁共振成像T2序列信号高强度之间存在关联,肿瘤的一致性很重要,因为手术难度和时间取决于此。T2病变的高强度与手术中看到的肿瘤的软稠度有关,而T2的低强度脑膜瘤与硬稠度有关。
