The purpose of the present study was to investigate the feasibility and usefulness of three-dimensional (3D) multislice computed tomography (CT) angiography with maximum intensity projection (MIP) and volume rendering (VR) in six dogs with clinical and sonographic findings suggestive of portosystemic shunt. Furthermore, we aimed to estimate the diameter of the portal vein and shunt vessels. MIP and VR reconstructions were performed for each patient and the origin and insertion of all shunt vessels were detected. In addition, 3D reconstructions allowed excellent depiction of vascular morphology and topography. All diagnoses and vessel measurements were confirmed by surgery. 3D multidetector CT angiography is a promising, noninvasive, and accurate method of evaluating dogs with suspected portosystemic shunts.
本研究的目的是探讨三维（3D）多层螺旋计算机断层扫描（CT）血管造影结合最大密度投影（MIP）和容积再现（VR）技术，在六只具有临床和超声检查结果提示存在门体分流的犬中的可行性和实用性。此外，我们旨在估计门静脉和分流血管的直径。对每只犬进行了MIP和VR重建，检测到所有分流血管的起源和汇入部位。此外，三维重建能够出色地描绘血管形态和地形。所有诊断和血管测量均通过手术得到证实。三维多排CT血管造影是一种有前景的、非侵入性且准确的方法，用于评估疑似门体分流的犬。
