Depends: I assume you mean hydrocepahlus - aka "water on the brain". This is a condition with an abnormality in cerebrospinal fluid flow/production and results in increased pressure within the ventricular system. This can occur in infancy and is noted with a rapidly enlarging head, but can be acquired after infection or trauma/bleeding in the brain usually an head ultrasound or ct is done.

Hydranencephaly is…: Rare condition in which the brain's cerebral hemispheres are absent and replaced by sacs filled with cerebrospinal fluid. Mri may be best imaging format. See following nih site for more info on this condition http://www.Ninds.Nih.Gov/disorders/hydranencephaly/hydranencephaly.Htm.

Hydranencephaly is normally seen on ultrasound, and can be seen on the routine trimester ultrasounds that are performed during pregnancy. CT scans are another way to diagnose hydranencephaly. Just due to shear volume, I would think, ultrasound detects more hydranencephaly in newborns and in utero than MRI and CT scan combined.

Simple works: Hydranencephaly is often detected today by random ultrasound performed during an otherwise routine pregnancy. Many sophisticated methods can confirm this after birth but the simple one also works. The skull of a hydranencephalic newborn is thin will light up like a lantern in a dark room if a dark light is placed against the back of the skull.Investing with more expensive imaging is unnecessary.

What are imaging signs, symptoms of chiari malformations?

Dr. Seth Zeidman

Complex: The imaging part is straightforward - you see herniation of the cerebellar tonsils on an MRI scan. The symptoms can be more difficult to pinpoint - these include headaches, fatigue, muscle weakness in the head and face, difficulty swallowing, dizziness, nausea, impaired coordination, and, in severe cases, paralysis.

What imaging might I get in the emergency room (er)?

Dr. Timothy Mosher
Radiology 32 years experience
Depends on symptoms: X-rays or radiographs are the most frequent images obtained in the er and are used for diagnosing fractures and pneumonia. With severe trauma (ex car accident) ct is frequently used as well as for conditions such as appendicitis, kidney stones, and abdominal conditions. Ultrasound is used for conditions such as gallstones, pregnancy. Mri may be used for evaluation of the brain or spine.

Is it normal to start seeing or imaging stuff while im high?

Dr. Paul Aitchison

Depends: On what you are using to get high. There are many psychotropic drugs that may cause hallucinations. Although marijuana does not typically cause hallucinations per se, it could be laced with a stronger drug.
