ABSTRACT
Objective To evaluate the clinical utility of ROI(region of intest)volume measurement for interventional embolization of the oral and maxillofacial AVM before intervention.Methods four patients with oral and maxillofacial AVM were undertaken,ROI volume measurement of AVM by GE AW 4.1 software based on the MRI and MSCT imaging data,and the quantity of embolic agent was administered correspondingly to the measured volume of AVM lesion and then,the therapeutic effect was observed.Results In 3 cases of this series,the volume of AVM lesions obtained by ROI volume measurement based on the imaging data were 7.515 cm3,1.195 cm3 and 10.714 cm3,respectively;gaining all the therapeutic satisfactory effects.However,the volume of the other case was not achieved because of the bilateral diffuse AVM with previous ligation of feeding arteries.Conclusions Soft tissue AVM can be best demonstrated on MRI and MSCT therefore can display AVM of jaw clearly.Pre-embolization of oral and maxillofacial AVM,the quantity of embolic agent(especially the liquid agent) can be estimated correctly by the ROI volume measurement used GE AW 4.1 software.
