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.
CT and MRI are most commonly used to observe the brain for cerebral atrophy. A CT scan takes cross sectional images of the brain using X-rays, while an MRI uses a magnetic field. With both measures, multiple images can be compared to see if there is a loss in brain volume over time. [20]
Cases of cerebral softening in infancy versus in adulthood are much more severe due to an infant's inability to sufficiently recover brain tissue loss or compensate the loss with other parts of the brain. Adults can more easily compensate and correct for the loss of tissue use and therefore the mortality likelihood in an adult with cerebral ...
A CT scan is the best test to look for bleeding in or around your brain. In some hospitals, a perfusion CT scan may be done to see where the blood is flowing and not flowing in your brain. Magnetic resonance imaging (MRI scan): A special MRI technique (diffusion MRI) may show evidence of an ischemic stroke within minutes of symptom onset. In ...

Those with parenchymal contusion would require frequent follow-up imaging because such contusions may grow large enough to become hemorrhage and exerts significant mass effect on the brain. [ 3 ] Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter .
The most common symptoms of CNS tumors are headache, vomiting, and nausea. Symptoms vary depending on the tumor and may include unsteady gait, slowed speech, memory loss, loss of hearing and vision, problems with memory, narrowing of visual field, and back pain. Symptoms may also vary greatly between individuals with the same tumor type.
Metastasis is the most common cause of brain cancer, as primary tumors that originate in the brain are less common. [4] The most common sites of primary cancer which metastasize to the brain are lung, breast, colon, kidney, and skin cancer. Brain metastases can occur months or even years after the original or primary cancer is treated.
