Cerebrospinal fluid (CSF) flow MRI ... CSF is a clear fluid that surrounds the brain and spinal cord. [3] The rate of CSF formation in humans is about 0.3–0.4 ml ...
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
[citation needed] The survival rate for CNS tumors is around 60%. Pediatric brain cancer is the second-leading cause of childhood cancer death, just after leukemia. Recent trends suggest that the rate of overall CNS tumor diagnosis is increasing by about 2.7% per year.
Cerebrospinal fluid (CSF) is a clear, colorless transcellular body fluid found within the meningeal tissue that surrounds the vertebrate brain and spinal cord, and in the ventricles of the brain. CSF is mostly produced by specialized ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid granulations .
Radiologist interpreting MRI images of head and neck. MRI is the investigation of choice in the preoperative staging of rectal and prostate cancer and has a role in the diagnosis, staging, and follow-up of other tumors, [28] as well as for determining areas of tissue for sampling in biobanking.

Short-TI Inversion Recovery (STIR) is also commonly added to the MRI protocol for detecting spinal cord tumors. [1] Myelography may be used as a substitute when the patient cannot undergo an MRI or it is unavailable. [1] X-rays and CT are more commonly used to view the bony structures. [5] They are less frequently used for spinal cord tumors ...
