Neuroradiology is a subspecialty that concentrates on pathology affecting the head, neck and spine. Utilizing modalities such as CT, MRI and myelography the diagnosis and treatment of complex medical issues is expedited. Various diseases involving these areas such as congenital abnormalities, cancer, infection and arthritis can be evaluated and treated effectively, resulting in optimal patient outcomes. Neuroangiography is a more invasive vascular test equipped to evaluate and treat aneurysms, strokes and vascular malformations.
