ABSTRACT
Objective To analyze the features of intracrayze the features of intracranial cystic diseases on ~1H MRS,and to evaluate the applicable value of ~1H MRS.Methods Fifty-two patients were examinated by single voxel ~1H MRS,included Ⅰ-Ⅱ graded astrocytomas(n=8),glioblastomas(n=9),metastasis(n=13),brain abscesses(n=10),epidermoids(n=4),anachnoid cysts(n=5),brain Cysticerciasis(n=3).Results(1)There was only Lac in Ⅰ-Ⅱ graded astrocytomas.But in glioblastomas,as were as all showed Lac,4 cases showed low Cho and NAA and 2 cases Lip.(2) In(13 metastasis) patients,7 cases only presented Lac,6 cases showed Cho,3 cases showed low NAA and(6 ones) Lip.(3) In brain abscesses,all showed Lac,9 cases displayed AA,6 cases showed Ace,5 cases appeared Suc and Ala,2 cases had Lip.(4) Four cases of epidermoid showed Lac,one showed Lip.In(4 arachnoid) cysts,2 cases had low Lac,one showed Lip.Three cases of cysticerciasis showed Lac,Ace,Suc,Ala and no AA,Cho,NAA.Conclusion Lac is the most common resonance peak on ~1H MRS in intracranial cystic diseases and for no diagnostic specificity.AA combined Ace,Suc,and Ala are highly specificity for brain abscess.Ace,Suc and Ala appearance cues the the possible existence of cysticerciasis.~1H MRS is helpful for the qualitative diagnosis of intracranial disease.
