Review of Imaging Autism Spectrum Disorders with Magnetic Resonance Imaging Techniques

Abstract

The pattern of autism spectrum disorder (ASD) at early stage may be identified, but difficult to conclude to some extent with specific classification. Multiple researches and reviews published in recent years to exactly define ASD patterns. Radiological imaging modalities proved significant role in imaging ASD at early stage. This configurative review aims to provide detailed importance of ASD imaging with various MRI techniques, specific to neuroanatomical regions and physiological functions; with techniques like MR spectroscopy, Diffusion tensor imaging and functional MRI imaging. The review is done by three researchers independently after selecting 32 published articles from various web sources. The present review concludes need of further research towards ASD pattern-based evolution of techniques in MR imaging; and provides various MR imaging aspects of neuroanatomy and the physiological functions of brain, specific to ASD patterns.
