The brain parenchyma is the essential functional tissue of the brain, consisting of gray matter and white matter. Imaging techniques like MRI, CT scans, PET scans, fMRI, are tools for studying brain parenchyma, allowing us to better understand its structure and function.
A normal brain parenchyma should have a consistent texture and density, with clear differentiation between gray and white matter. Any abnormalities, such as lesions or atrophy, can be indicative of underlying brain pathology .
The brain parenchyma refers to the functional tissue in the brain that is made up of the two types of brain cell, neurons and glial cells. [7] It is also known to contain collagen proteins. [8] Damage or trauma to the brain parenchyma often results in a loss of cognitive ability or even death.
A parenchymal hemorrhage is a bleed that occurs within the brain parenchyma and can lead to the disruption of oxygen in brain cells and subsequent functional tissue death. There are two types of parenchymal hemorrhages: primary and secondary.
Brain atrophy is an important feature of many neurodegenerative disorders. It can be described in terms of change in the brain parenchymal fraction (BPF). In order to interpret the BPF in disease, knowledge on the BPF in healthy individuals is required.
Thus, for the sake of simplicity, here we model the brain parenchyma as consisting of only two compartments: glial (approximated as the number of non-neuronal cells) and neuronal.
Learn the anatomy of the cerebral lobes relevant to CT brain interpretation. The frontal lobes are the largest lobes of the brain. Other lobes of the brain are the parietal lobes, temporal lobes and occipital lobes.
In the brain parenchyma, neurons can be dispersed or organized into layers depending on the brain region, while glial cells are generally dispersed, occupying satellite positions around neuronal cell bodies or interacting structurally with one another (Peters et al., 1990).
Parenchyma is commonly defined as “the functional tissue of an organ as distinguished from the connective and supporting tissue” [7]. You might find these chapters and articles relevant to this topic. In Diagnostic Pathology: Head and Neck (Second Edition), 2016.
The brain is an organ composed of nervous tissue that commands task-evoked responses, movement, senses, emotions, language, communication, thinking, and memory. The three main parts of the human brain are the cerebrum, cerebellum, and brainstem. See Image. Human Brain, Encephalon.
