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.
Although anaplastic meningioma has higher chances of distant metastasis than the other two types, the overall incidence of meningioma metastasis is only 0.18%; which is considered rare. [26] Even if, by general rule, neoplasms of the nervous system (brain tumors) cannot metastasize into the body because of the blood–brain barrier , anaplastic ...
A brain metastasis is a cancer that has metastasized (spread) to the brain from another location in the body and is therefore considered a secondary brain tumor. [ 1 ] [ 2 ] The metastasis typically shares a cancer cell type with the original site of the cancer. [ 3 ]

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 ...
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 ...
The first study of the human brain at 3.0 T was published in 1994, [13] and in 1998 at 8 T. [14] Studies of the human brain have been performed at 9.4 T (2006) [15] and up to 10.5 T (2019). [ 16 ] Paul Lauterbur and Sir Peter Mansfield were awarded the 2003 Nobel Prize in Physiology or Medicine for their discoveries concerning MRI.
