Application of 3D-CT Angiography of Intracranial and Neck Diseases

Purpose: To evaluate three dimensional spiral CT angiography(3D - SCTA)in diagnosis of head and neck diseases. Materials and Methods: 3D - SCTA were carried out for 98 cases with diseases of head and neck, including intracranal aneurysm(n = 32) , cerebral AVM(n = 5), carotid arteriosclerosis(n = 35), extra - dural cavenous angioma(n = 2), meningioma(n = 11) , skull base neurofibroma(n = 3), tumor of neck soft tissue(n = 6) , and intracanal neurofibroma(n = 4). Results: Thirty of 32 cerebral aneurysms were delineated, including the neck and axis of aneurysm, as well as the supplying artery. 3D - SCTA clearly demonstrated of carotid arteriosclerotic plague. In 16 intracranial tumors the relationship between tumors and surrounding bony structures, such as cervical spine and foramina of skull base, and vessels, such as Willis circle, dural sinus and neck vessels, could be directly demonstrated. The range and conformation of 4 neurofibroma in cervical canal could be detected. 3D imaging reconstruction associated with pseudocolourful demonstration provided imitation of surgical intervention which was of great help for surgeons in preoperative diagnosis and therapeutic decision. Conclusion: 3D - SCTA is an simple, non- invasive , low - cost and reliable imaging technique in the diagnosis and therapeutic decision of intracra- nial, head and neck diseases. It is expected to be the first imaging choice in evaluation of intracranial, head and neck diseases in the near future.
