Application value of MR spectroscopy in the peritumoral tissue of brain astrocytic tumours
摘要
Abstract
Objective: To discuss metabolic feature in the peritumoral tissue of different ranks brain astrocytic tumours with multi-voxel proton magnetic resonance spectroscopy (1H-MRS), and estimate its application value on of brain astrocytic tumours. Materials and Methods:82 patients with brain astrocytic tumours conifrmed by postoperative pathologic were collected, which were divided into low grade astrocytic tumours (WHO I-II) 32 cases, and high grade astrocytic tumours (WHO III-IV) 50 cases. The semiquantitative and relatively quantitative ratio of metabolic of the parenchyma area,peritumoral tissues area,and area with normal area were measured, and value was set as P<0.05. Results:The relative quantitative ratios of Cho/Cr, Cho/NAA significantly differed in peritumoral tissues area of the high grade astrocytic tumours and the low grade astrocytic tumours (P<0.01), but NAA/Cr had no signiifcant difference (P>0.05). Conclusions: The changes of the MRS quantitative ratio in brain astrocytic tumours peritumoral tissues area relfects the level of different tumor biological behavior, and it has important clinical value in determining the classiifcation of the brain astrocytic tumours and the scope of attack.关键词
