Abstract
CT is routinely used in the investigation of diseases of the central nervous system (CNS). Its defects, however, became apparent along with its merits. Some of the defects of CT include:
-
1.
It is sometimes not possible to differentiate between brain tumor and normal brain material, or to clearly identify the boundary of a perifocal edema.
-
2.
The relationship between tumor, skull base, and tentorium cerebelli can often not be clearly defined.
-
3.
The presence of artifacts may make it impossible to visualize posterior fossa tumors.
-
4.
There is an accumulation of irradiation due to repeated follow-up examinations.
