Cerebrum: Anatomical Overview II

Cerebrum: Anatomical Overview II

Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...

Cerebral Hemispheres

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Spinal Cord: Cross-sectional Anatomy

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
Gray Matter and its Components
Central to the gray matter is...

Imaging Studies for Cardiovascular System V: CT

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Area of Science:

Neuroimaging
Radiology
Neuroanatomy

Background:

The corpus callosum (CC) is a critical white matter tract connecting cerebral hemispheres.
Lesions within the CC can impact neurological function.
Accurate diagnosis of CC pathologies is essential for patient management.

Purpose of the Study:

To illustrate the diverse imaging features of the corpus callosum (CC).
To review the role of Magnetic Resonance Imaging (MRI) in evaluating CC abnormalities.
To discuss the added value of diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) for CC assessment.

Main Methods:

Review of neuroimaging literature focusing on the corpus callosum.
Analysis of MRI, DWI, and DTI findings in various CC pathologies.
Correlation of imaging features with known pathological conditions.

Main Results:

Magnetic resonance imaging (MRI) is the primary modality for CC evaluation.
Diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) provide crucial insights into white matter integrity and microstructural changes.
Characteristic imaging patterns are associated with different types of CC lesions.

Conclusions:

MRI, particularly with DWI and DTI, is indispensable for diagnosing corpus callosum pathologies.
Understanding these imaging features aids in differentiating various CC lesions.
This review provides a comprehensive overview for radiologists and neurologists.
