Clinical imaging of brain tumors are the following:
Imaging of brain tumors (1) skull X-ray: the elderly can present course of the disease signs of increased intracranial pressure can be used as diagnostic reference.
Imaging of brain tumors (2) cerebral angiography: After femoral artery catheterization for vertebral artery angiography or carotid angiography, can be used for localization diagnosis, and can see the pathologic blood vessels, showed a small irregular vascular network group and tumor staining, and sometimes shows a large supply arteries.
Brain tumor imaging (3) CT scan: solid tumor showed round-like high density, density can be mixed evenly, after injection of contrast agent can be showed homogeneous enhancement, edema around the tumor may have low-density zone, but often obvious, cystic tumors can present low density, the edge is still clear, and sometimes that broke into the tumor nodules higher density of cysts, injection of contrast medium, the nodules was significantly enhanced.
Imaging of brain tumors (4) magnetic resonance imaging CMRI): For small tumors better than CT, the images clear, the relationship between the tumor and the brain stem, but seems to be no specific characterization, in general, cystic tumor, T1-weighted mixed signals for the low, T2-weighted for the advanced mixed signal.
adults increased intracranial pressure, a history of skull in about six months after the police who should be suspected.
other body organs of patients with vascular network, when there is neurological symptoms or signs, such as the change again at the end, the base can be recognized as disease, hair retinal vascular network showed a red cell tumor from the tumor, and a tortuous arteries and the associated thick, around the tumor was more than a mild choroid.
increased intracranial pressure associated with a family history of the disease, and high hemoglobin cells increased, should consider this in the.
reticular cells substantive vascular X-ray contrast tube thin present their diagnosis.
