Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Summary

Hemimegalencephaly can present with unusual mid-sagittal structures. This study investigates if these band-like formations seen on MRI are aberrant fibers in unilateral hemimegalencephaly.

Background:

Hemimegalencephaly is a rare congenital brain malformation.
Mid-sagittal band-like structures between lateral ventricles are often observed in hemimegalencephaly on MR imaging.

Purpose of the Study:

To describe the clinical presentation and MR imaging findings in a patient with unilateral hemimegalencephaly.
To investigate the nature of mid-sagittal band-like structures using advanced MR techniques, specifically diffusion tensor MR and fiber tract reconstruction.
To determine if these structures represent aberrant mid-sagittal fibers.

Main Methods:

Retrospective examination of MR images from a 14-year-old boy with unilateral hemimegalencephaly.
Utilized conventional MR imaging, diffusion tensor MR, and fiber tract (FT) reconstruction.
Analyzed morphologic abnormalities and clinical presentation.

Main Results:

Detailed description of the clinical presentation and morphologic abnormalities.
Conventional MR imaging revealed characteristic findings of unilateral hemimegalencephaly.
Diffusion tensor MR and fiber tract reconstruction were employed to analyze the mid-sagittal structures.

Conclusions:

The study aimed to elucidate the origin of enigmatic mid-sagittal structures in hemimegalencephaly.
Advanced MR techniques were used to differentiate these structures from normal white matter tracts.
Findings contribute to understanding the complex neuroanatomy in hemimegalencephaly.
