Complementary role of computed tomography and other neuroradiologic procedures.

Although a probable initial diagnosis may be suggested by computed cranial tomography, the diagnostic accuracy is often increased by the complementary use of other neuroradiologic studies. The use of CT scanning is conjunction with other more invasive neuroradiological studies results in improved diagnosis and patient management in almost the entire spectrum of neurosurgical diseases-- subarachnoid hemorrhage due to aneurysm, stroke, trauma, normal pressure hydrocephalus, and especially neoplasms.
