Abstract:
Objective To explore the clinical application of blood perfusion quantitatively by contrastenhanced ultrasonography(CEUS) to grade cerebral gliomas during operation. Methods Thirty-one patients with cerebral gliomas were examined by CEUS with Sonoliver software during operation. Maximum intensity (IMAX), time to peak (TTP), rising time (RT) and mean transit time(mTT) of the regions of interest (ROIs) of normal brain tissue and high- and low-grade gliomas were respectively determined and comparatively analyzed. Results Fifteen high-grade gliomas and sixteen low-grade gliomas were postoperatively confirmed by pathologic results. The administration of contrast agent led to higher echo enhancement in cerebral gliomas than normal brain tissues in all cases. The TTP of high- and low-grade gliomas were significantly shorter than that of normal cerebral tissues ( P ＜0.05) ,and the mTT was longer than that of normal brain tissue( P ＜0. 05). There was significant differences of IMAX and TTP between high- and low-grade gliomas(P ＜0.05), but there was no significant difference of RT and mTT between the two groups ( P ＞0.05). Conclusions CEUS with quantitative analysis software on blood perfusion of the tumors can provide valuable information to grade cerebral gliomas.
