Abstract:
The aim of this study was to determine if a contrast agent provides additional
information for characterization of brain lesion and normal tissue.
The advantages of magnetic resonance imaging (MRI) over other diagnostic imaging
modalities are its higher spatial resolution and its better discrimination of soft tissue.
This study of brain diseases relied on quantitative measures obtained from MR scans that
are segmented into the three common tissue types present in the human brain: cerebral gray
matter (GM), cerebral white matter (WM), and cerebral spinal fluid (CSF).
The study was carried out in Antalya Medical Center during the period from July to
October and included 63 brain lesion patients.
The performance of contrast agent was evaluated by measuring signal intensity and
comparing the diagnostic accuracy of MRI image with contrast and without contrast.
The results indicate that the same effect of Contrast on Lesion tissue and normal tissue for
all ages and for both males and females and the diagnosis doesn’t dependent on age or
gender.
The results showed the effectiveness of the contras agent and the achieved improvement
in image quality. As the contrast agent improves the detection of brain lesion according to
the type of lesion, this was clearly shown by the results.
Also the results indicate that the ability of contrast-enhanced MRI to identify additional
information for characterization of Pathological Brain Tissue and Enhanced the normal
tissue according to the type of tissue.
