DSA, Dyna-CT and MRI image fusion new technology progress in the application of cerebrospinal vascular disease

Objective In this study, we discuss the development of DSA and MRI image fusion technology and its application value in cerebral spinal vascular disease. Methods Application of our hospital Siemens Artis Zee with Dyna-CT introduced in 2011 and GE-3100 with Innova-CT introduced in 2006 and them post-processing software: such as Dural Volume, Intravenous CTA, Three dimensional Fusions, Parenchyma blood Volume (PBV), Siemens iFlow and GE-Agioviz, etc. When in the clinical interventional diagnosis and treatment of cerebrospinal vascular disease, three dimensional fusion image, cerebral blood volume and full cycle of the cerebral blood flow images were obtained by 3D reconstruction, 3D fusion and so on post-processing technology after DSA angiography. Results Using two DSA machine to reconstruct dural volume, we can evaluate intracranial and neck stent expanded after placement and the effect of embolization of intracranial aneurysms, and determine whether intracranial artery and aneurysm presence of calcification, as well as identify intracranial and spinal vascular lesions relationship with the skull, skull base and spine bone structure in orthotopic, lateral and axial. We can apply the CTA evaluation of intracranial vascular lesions, such as aneurysm, AVM and so on. We can evaluate cerebrovascular diseases, especially the AVM blood supply, through the bilateral internal carotid artery system, unilateral internal carotid artery system and unilateral vertebral artery DSA three-dimensional vascular remodeling. We find out the new reference index of the gold standard of internal carotid artery occlusion by observing cerebral blood volume changes before and after the fall blood pressure BOT(balloon occlusion test). We built the full cycle image of brain arteries, veins and venous sinus and have successfully completed the fistula operation of deep intracranial aneurysm and arteriovenous via input the DSA and MRI images fusion data to Mecromic neural navigation. Conclusions Three-dimensional imaging fusion of DSA, CT and MRI images have great reference value in the diagnosis and treatment of cerebral spinal vascular disease, even have more intuitive and valuable help to the scientific research and teaching. A variety of image fusion is the future development direction of medical image.
