体视学法在颅内血肿体积测量的应用

目的介绍改进后的体视学法测量颅内血肿体积,并验证其准确性。方法在92例颅内出血的CT图像上,同时运用体视法、CT定量法测量颅内血肿体积,以CT定量法的结果为标准验证体视法的准确性。结果按血肿体积大小分为5组,各组CT定量法、体视学法所测得体积采用配对样本的t检验分析P值皆大于0.05,即CT定量法、体视学法所测血肿体积无统计学差异。结论体视学法测量颅内血肿准确可靠,在CT工作站对颅内血肿病例行胶片打印排版时,在图像上加上合适的网格,可方便临床医生快速运用体视法准确测量颅内血肿体积。

The Application of Stereology in Intracranial Hematoma Volume Measurement

Objective The volume of intracranial hematoma was measured by the improved stereology, and its accuracy was verified.Methods In the CT images of 92 cases of intracranial hemorrhage, the volume of intracranial hematoma was measured by stereology and CT quantitative method, and the accuracy of the stereology was verified by CT quantitative method.Results It was divided into 5 groups with hematoma volume. Results of the P value was more than 0.05 in all groups intracranial hemorrhage that T test analysis of the CT quantitative method was paired samples by the method of stereology, it can be found that they were no statistical difference in the volume of hematoma between the CT quantitative method and the stereology.Conclusions It is accurate measuring the volume of intracranial hematoma by stereology. When the CT film is be prepared for printing at the CT workstation, using image fusion of CT image and scalegrid can be convenient for radiologists and clinicians to use the stereology for the volume of intracranial hematoma.
