Brain MRI of a patient diagnosed with primary cardiac angiosarcoma that metastasised to the brain. MRI scans use strong magnetic fields and radio waves to create an image, while CT scans use X-rays. MRI scans produce more detailed images of bodily structures, particularly soft tissues including the brain, [13] and are better at detecting CNS ...
Central neurocytoma (CNC) is an extremely rare, ordinarily benign intraventricular brain tumour that typically forms from the neuronal cells of the septum pellucidum. [1] The majority of central neurocytomas grow inwards into the ventricular system forming interventricular neurocytomas.
The prognosis for brain metastases is variable; it depends on the type of primary cancer, the age of the patient, the absence or presence of extracranial metastases, and the number of metastatic sites in the brain. [6] For patients who do not undergo treatment the average survival is between one and two months. [6]

In analysis of the fetal brain, MRI provides more information about gyration than ultrasound. [24] MRI is sensitive for the detection of brain abscess. [25] A number of different imaging modalities or sequences can be used with imaging the nervous system: T 1-weighted (T1W) images: Cerebrospinal fluid is dark.
PXA as visualized on an MRI. PXA is diagnosed through a combination of diagnostic processes: Initially, a doctor will interview the patient and do a clinical exam, which will include a neurological examination. A CT scan of the brain, and/or an MRI scan of the brain and spine, will be performed. A special dye may be injected into a vein before ...
A study looking at ultra-detailed MRI scans of people hospitalized with severe COVID-19 found that the disease affects the brainstem, a region of the brain responsible for controlling many key ...
Gliomatosis cerebri is a rare growth pattern of some brain tumors, impacting at least three cerebral lobes, mostly with bilateral involvement of the cerebral hemispheres. It can be seen in some types of diffuse glioma, most notably glioblastoma. It consists of infiltrative threads that spread deeply into the brain, making them very difficult to ...
