Fractal characterization of normal cerebral ventricles in t2-wheigthed magnetic resonance imaging
Velasco, Alejandro | 2017-10
Introduction: The fractal geometry describes adequately the
irregularity of the natural objects such as the cerebral ventricles,
which are irregular structures that can be characterized through the
Objective: This research aims to develop a new methodology of
geometric characterization of the cerebral ventricles, based on the
fractal geometry for the analysis of normal cerebral ventricles.
Methods: Based on the Box-Counting method, the fractal
dimensions of the both lateral ventricles of a normal adult were
obtained. Sequential cephalic-caudal 4mm axial slices were acquired
on T2-WI, and the differences and similarities of the lateral ventricles
were established using the Ventricular Intrinsic Mathematical
Results: The fractal dimension of the left lateral ventricle had
values between 1.0641 and 1,3599, and in the right lateral ventricle
had values between 0.8931 and 1.3219.
Conclusion: A new morphometric measure of the cerebral
ventricles was developed based on the fractal geometry for its use as
an objective and reproducible measure.
