Susceptibility‐weighted imaging (SWI) is a magnetic resonance imaging (MRI) technique that enhances image contrast by using the susceptibility differences between tissues. The strength of SWI is in its ability to identify hemorrhage, calcium and nonheme iron by virtue of its susceptibility artifact, Susceptibility weighted imaging (SWI) has become a key MR sequence in pediatric neuroimaging.
Aim of the work
The aim of this study is to identify the added value of Susceptibility Weighted Imaging (SWI) in evaluation of non-traumatic pediatric brain lesions.
Subjects and Methods
Subjects:
The study was conducted on 20 patients .
All the patients were below 18 years old from both genders and with history of non traumatic brain lesions.
Methods:
The studied patients were subjected to the following:
• Full detailed history taking and thorough clinical examination.
• MRI examination of brain including :
 Routine magnetic resonance imaging:
• T1 weighted axial sequences.
• T2 weighted axial sequences.
• Fluid-attenuated inversion-recovery (FLAIR) axial sequences.
 Axial susceptibility imaging (SWI)
