In CT scan, subdural hygroma will have same density as the normal CSF. Meanwhile, in MRI, subdural hygroma will have same intensity with CSF. If iodinated contrast is administered during CT scan, the hygroma will produce high density because of the contrast at 120 kVp. However, at 190 kVp, hygroma with contrast will have intermediate density.
A CT scan is typically performed after radiographic contrast media (dye) has been placed with fluoroscopic guidance into a sac-like lining (the first- and hardest and outermost- layer of the spinal meninges, the spinal dura mater) surrounding the spinal cord and nerves. The material is typically water-soluble, which has largely replaced ...
CT scan (computed tomography) of the brain (without any iodinated contrast), is the initial imaging choice because of its high speed, good accessibility in hospitals, high sensitivity in detecting brain injuries or brain diseases, thus helping to triage patients in emergency department in a timely manner and urgent neurosurgical intervention ...

A CT scan or MRI scan will usually detect significant subdural hematomas. [citation needed] Subdural hematomas occur most often around the tops and sides of the frontal and parietal lobes. [3] [2] They also occur in the posterior cranial fossa, and near the falx cerebri and tentorium cerebelli. [3]
Brazilian President Luiz Inacio Lula da Silva underwent a craniotomy in Sao Paulo to drain a subdural hematoma linked to a fall at home on Oct. 19, according to a medical note published by the ...
CT images of the head are used to investigate and diagnose brain injuries and other neurological conditions, as well as other conditions involving the skull or sinuses; it used to guide some brain surgery procedures as well. [2] CT scans expose the person getting them to ionizing radiation which has a risk of eventually causing cancer; some ...
