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 ...
Magnetic resonance imaging uses strong magnetic fields, magnetic field gradients, and radio waves to generate images of the structure of the brain. In perfusion MRI a contrast agent , such as gadolinium compounds, may be used to study the structure of the blood vessels around the tumor that provide nutrients and remove waste. [ 13 ]
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 ]

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.
In the CNS a tumor may be a secondary malignant tumor having metastasised (spread from a primary site in the body). Treatment and prognosis depend on factors such as the type of tumor, location, and molecular characteristics. [1] Although primary nervous system neoplasms are relatively rare, secondary (metastatic) tumors are more common in ...
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 ...
The first MR images of a human brain were obtained in 1978 by two groups of researchers at EMI Laboratories led by Ian Robert Young and Hugh Clow. [1] In 1986, Charles L. Dumoulin and Howard R. Hart at General Electric developed MR angiography, [2] and Denis Le Bihan obtained the first images and later patented diffusion MRI. [3]
