Computed Tomography of Diseases

CT has been widely used and found to be useful in the diagnosis of various intracranial diseases such as brain tumors, cerebrovascular diseases, head traumas, central nervous system anomalies, infectious diseases, and atrophic and degenerative diseases. It is now an essential diagnostic method in the field of neuroradiology. CT is superior to conventional neuroradiological examinations such as cerebral angiography and pneumoencephalography (PEG) due to its noninvasive nature and usefulness in screening examinations. Because of its excellent density resolution, CT has the additional important advantage of being able to visualize the cerebral parenchyma.
