Distinction between high-grade gliomas and solitary metastases using peritumoral 3-T magnetic resonance spectroscopy, diffusion, and perfusion imagings

摘要: This study compared the effectiveness of relative cerebral blood volume, apparent diffusion coefficient, and spectroscopic imaging in differentiating between primary high-grade gliomas solitary metastases. A 3.0-T MR unit was used to perform proton spectroscopy, imaging, conventional on 26 patients who had brain tumors (14 12 metastases). All diagnoses were confirmed by biopsy. Twelve perfusion studies (8 4 metastases) also performed. The results showed that choline creatine ratio volume peritumoral regions significantly higher than they coefficient values tumoral metastases gliomas. Although characteristics may sometimes be similar, perfusion-weighted enable distinction two. Diffusion-weighted techniques complementary make a differential diagnosis two malignant tumors.
