The cerebellum: 3. Anatomic-MR correlation in the coronal plane

Area of Science:

• Neuroimaging
• Radiology
• Anatomy

Background:

• Coronal magnetic resonance imaging (MRI) is a valuable tool for visualizing brain structures.
• Understanding the detailed anatomy of the cerebellum is crucial for diagnosing neurological conditions.

Purpose of the Study:

• To correlate thin coronal MRI scans of the cerebellum with myelin-stained sections.
• To evaluate the utility of coronal MRI for identifying cerebellar anatomy and potential abnormalities.

Main Methods:

• Acquisition of thin (5-mm) coronal 1.5-T MRI scans of human brain specimens and normal volunteers.
• Correlation of MRI findings with myelin-stained microtomic sections of cerebellar specimens.
• Utilized proton-density, T1, and T2-weighted spin-echo sequences for optimal contrast.

Main Results:

• Coronal MRI clearly depicts white matter tracts and fissures oriented perpendicularly to the imaging plane, offering excellent gray-white matter and CSF-parenchyma contrast.
• Side-to-side comparison of cerebellar hemispheres is facilitated by the coronal view.
• Obliquely oriented structures and finer vermian details may be obscured by volume averaging.

Conclusions:

• Coronal MRI provides excellent visualization of key cerebellar white matter tracts and fissures, enabling detailed anatomical mapping.
• This imaging plane is particularly useful for identifying, localizing, and quantifying morphologic differences between cerebellar hemispheres.
• Coronal MRI is a promising technique for assessing normal and abnormal cerebellar anatomy.
