Abstract: Objective ?To explore the clinical value of magnetic resonance spectroscopy in differentiating primary brain tumor from metastatic tumor.Methods ?Analysis of 32 cases of primary brain tumor treated in our hospital from January 2012 to May 2018 and clinical data of 25 patients with craniocerebral metastases was made and they were recorded as group A and group B respectively.MRS examination was performed on diagnosis, and Cho/Cr,NAA/Cr,Cho/NAA were calculated and compared between the two groups.Results ?The Cho/Cr,Cho/NAA of group A was (3.12±1.02), (3.18±1.05), that of group B was (1.96±0.53), (2.03±0.65), group A was higher than group B, the difference was statistically significant (P<0.05).The NAA/Cr of group A was(1.12±0.31) and group B was(1.47±0.37), respectively, group A was significantly lower than those of group B,the difference was statistically significant(P<0.05).Conclusion ?The relative concentrations of metabolites in the parenchymal regions of primary brain tumor and metastatic tumor are quite different. MRS diagnosis can be used to differentiate and assist in the diagnosis of primary brain tumor in order to provide scientific basis for treatment.

顱腦原發(fā)性腫瘤(primary brain tumor)與腦轉(zhuǎn)移瘤(brain metastases)是臨床發(fā)病率較高的腦腫瘤,其中腦轉(zhuǎn)移腫瘤占據(jù)腫瘤總數(shù)的1/5左右[1]。通常情況下,腦轉(zhuǎn)移瘤是腦實(shí)質(zhì)的多發(fā)病灶,并且部分患者具有其他部位原發(fā)惡性腫瘤病史,結(jié)合影像學(xué)檢查能夠確診。MRI是鑒別兩種腫瘤的重要手段,然而在多數(shù)情況下其圖像特異性不足,特別是在轉(zhuǎn)移瘤單發(fā)或原發(fā)性腫瘤多發(fā)但患者臨床表現(xiàn)與病史無(wú)鑒別價(jià)值時(shí),難以獲取正確診斷結(jié)果。隨著醫(yī)學(xué)診斷技術(shù)的進(jìn)步,磁共振波譜(Magneticresonancespectrum,MRS)應(yīng)用范圍不斷拓寬,其是通過(guò)磁共振化學(xué)位移現(xiàn)象對(duì)物質(zhì)分子成分進(jìn)行測(cè)定的檢測(cè)技術(shù),可用于顱內(nèi)腫瘤生化與代謝物變化的觀察。由于大部分腫瘤病理波譜特征相似,臨床上關(guān)于MRS是否能進(jìn)一步鑒別存在一定爭(zhēng)議。有國(guó)外學(xué)者指出,瘤周代謝物差異可能具有一定鑒別價(jià)值[2]。本研究通過(guò)對(duì)比兩種腫瘤周?chē)x物成分與變化,探究顱腦原發(fā)性腫瘤與轉(zhuǎn)移瘤鑒別中MRS的臨床價(jià)值,現(xiàn)報(bào)道如下。……
