Endovascular treatment and prognosis of intracranial aneurysms are based on size and volume, which demand more accurate neuroimaging techniques. Aneurysm volume calculation is important to choose endovascular treatment modalities and packing density calculation. Of all these methods, it remains unknown which one is the most accurate to calculate aneurysm volume. The objective of this study is to compare the accuracy of three angiography-based versus three tomographic-based methods which calculate aneurysm volume. A retrospective study which included patients with ruptured and unruptured cerebral aneurysms diagnosed by angiogram and computed tomography angiography (CTA) was done. The accuracy of each method was assessed with an ellipsoid glass model of known volume, which helped us to adjust variation in volumetric measurements done with AngioSuite© and AngioCalc© softwares (based on angiographic and tomographic images), 3D-rotational angiography and 3D-CTA (tridimensional computed tomography angiography), based on measurements of diameters such as maximal width and maximal height. Descriptive statistics, ANOVA for repetitive samples and t test were used. We included 89 patients (126 saccular intracraneal aneurysms). AngioSuite© software (angiography-based) showed more accuracy compared to other methods in our control model. The geometric system (AngioCalc) based on CTA images was statistically different from all other methods studied. AngioCalc (CTA-based) demonstrated a significant difference compared with other methods hence, it may overestimate volume measurements. AngioSuite
颅内动脉瘤的血管内治疗及预后取决于其大小和体积，这就需要更精确的神经影像技术。动脉瘤体积计算对于选择血管内治疗方式及填充密度计算至关重要。在所有这些方法中，尚不清楚哪种方法计算动脉瘤体积最为准确。本研究的目的是比较三种基于血管造影的方法与三种基于断层扫描的方法在计算动脉瘤体积方面的准确性。我们进行了一项回顾性研究，纳入了通过血管造影和计算机断层扫描血管造影（CTA）诊断为破裂和未破裂脑动脉瘤的患者。每种方法的准确性通过已知体积的椭球体玻璃模型进行评估，这有助于我们根据最大宽度和最大高度等直径测量值，对使用AngioSuite©和AngioCalc©软件（基于血管造影和断层扫描图像）、三维旋转血管造影和三维CTA（三维计算机断层扫描血管造影）进行的体积测量变化进行调整。使用了描述性统计、重复样本的方差分析和t检验。我们纳入了89例患者（126个颅内囊状动脉瘤）。在我们的对照模型中，AngioSuite©软件（基于血管造影）显示出比其他方法更高的准确性。基于CTA图像的几何系统（AngioCalc）与所有其他研究方法在统计学上存在差异。AngioCalc（基于CTA）与其他方法相比显示出显著差异，因此，它可能高估体积测量值。AngioSuite
