An implication of this observation is. that two forms of RNA polymerase lI, differing in their subunit composition, may exist in vivo. The in vivo phosphorylation state of. RNA polymerase II subunits has also. been investigated using the immunopre-. cipitation approach (Fig.

Your doctor will order a test of the cerebrospinal fluid if you have symptoms of a ruptured aneurysm but a CT scan hasn't shown evidence of bleeding. The procedure to draw cerebrospinal fluid from your back with a needle is called a lumbar puncture, or spinal tap. Magnetic resonance imaging (MRI).An MRI uses a magnetic field and radio waves to create detailed images of the brain, either 2-D slices or 3-D images. A type of MRI that assesses the arteries in detail (MRI angiography) may detect the site of a ruptured aneurysm.Cerebral angiogram.our doctor will order a test of the cerebrospinal fluid if you have symptoms of a ruptured aneurysm but a CT scan hasn't shown evidence of bleeding.
