Dynamic CT Study of Intracranial Tumors / 昆明医科大学学报

ABSTRACT

The time-density curves were collected in 106 patients with intracranial tumors.A de- tailed analysis was made among 66 of them whose illness was determined surgically and pathologically.The scanning technique,method of administration of contrast material in dy- namic CT and its value in the qualitative and differential diagnosis of intracranial tumors were discussed.We consider that 1.dynamic CT scan is performed safely and reliably without trauma or pain on patients.2.Due to their various degrees of vascularity and disorders in the blood-brain barrier,different histological kinds of brain tumors have their own typical time-density curves.3.Vascular disorders such as aneurysm,angioma and arteriovenous mal- formation can be determined and differentiated from intracranial tumors or granuloma based on the typical time-density curves.4.Dynamic CT study is of some value in differential diagnosis of various kinds of brain tumors and is important in differentiation between brain tumors and granulomatous lesions.
