CT
- CT scan is not used in the diagnosis of Asperger Syndrome (AS).
MRI
- MRI is not used in the diagnosis of Asperger Syndrome (AS).
- However, several of studies have found abnormalities in MRI of AS patients which include:woody
- Abnormal activation in the inferior temporal sulcus.[1][2]
- Abnormal dysactivation of the frontal lobe while performing neuropsychological tests.[3][4][5][6]
- Abnormal functional integration of the amygdala and parahippocampal gyrus.[7]
- Abnormal structures in the inferior temporal gyrus, entorhinal cortex and rostral fusiform gyrus.[8]
- Missing tissue area in each hemisphere at the part where the middle frontal gyrus and the precentral sulcus intersect.[9]
- Lesion in the right middle temporal gyrus white matter.[10]
