Advantages Of Ct Scans
Compared to MRI scans, there are several advantages of CT scans. For larger individuals who may not fit comfortably inside traditional MRI devices, CT scans may be a better choice due to their more open design. Because this procedure produces results so much faster than an MRI, it is doctors preferred choice for a scanner for making a diagnosis in an emergency. When time is of the essence in determining the cause of stroke to start treatment, a CT scan cannot be matched. Doctors can identify if the stroke occurred from hemorrhaging or by a blocked artery.
Will A Cat Scan Identify If I Have Had A Concussion
A concussion is a blow to the head or any other part of the body that causes a shaking or a twisting injury to the brain. It can be called a functional injury of the brain as it changes how the brain functions, but generally doesn’t change how the brain appears. A CAT scan can help identify a structural injury to the brain, but not so much functional injuries. The reason why a CAT scan may be ordered is when an individual does not seem to be getting better after a concussive injury.
A person who has suffered a concussion may feel dizzy, nauseous, feel irritable, and have trouble concentrating. The signs and symptoms of a concussion are not relatable to visible damage to the brain on the CAT scan. More than 95% of concussions will not show any findings on a CAT scan.
However, If things take a turn for the worse such as a worsening headache, nausea and vomiting, seizures, weakness in the arms of legs, slurred speech, confusion, and drowsiness you may need to be assessed with an advanced imaging study of the brain such as a CAT scan that might show abnormalities such as a bleed in the brain, skull fracture, or actual damage to the brain tissue which can be visualized.
So although a concussion may not show up on a CAT scan in the emergency room immediately after the injury, this diagnostic test can be useful to look for signs of brain injuries other than a concussion.

What Are Some Common Uses Of The Procedure
CT scanning of the head is typically used to detect:
- bleeding, brain injury and skull fractures in patients with head injuries.
- bleeding caused by a ruptured or leaking aneurysm in a patient with a sudden severe headache.
- a blood clot or bleeding within the brain shortly after a patient exhibits symptoms of a stroke.
- enlarged brain cavities in patients with hydrocephalus.
- diseases or malformations of the skull.
CT scanning is also performed to:
- evaluate the extent of bone and soft tissue damage in patients with facial trauma, and planning surgical reconstruction.
- diagnose diseases of the temporal bone on the side of the skull, which may be causing hearing problems.
- determine whether inflammation or other changes are present in the paranasal sinuses.
- plan radiation therapy for cancer of the brain or other tissues.
- guide the passage of a needle used to obtain a tissue sample from the brain.
- assess aneurysms, arteriovenous malformations, and blood vessels through a technique called CT angiography. For more information, see the CT Angiography page.

- Non contrast head CT should be used in emergent settings. It has an excellent sensitivity for Intracranial hemorrhage and is widely available, cost effective, and shorter imaging time in comparison with MRI.
- Do not use contrast because it can potentially obscure small hemorrhages.
- Contrast can be utilized in a follow up exam if necessary
- Typically CT angiography to evaluate vasculature

Mild Traumatic Brain Injuries
About 75 percent of TBIs are classified as “mild.” The American Congress of Rehabilitation Medicine defines a mild TBI in “as a traumatically-induced physiological disruption of brain function” as evidenced by:
Brain injuries do not always have obvious or outwardly visible signs. Cognitive, psychological, and/or behavioral changes or impairments can go undiagnosed if ignored or misunderstood.
While 80-90 percent of injured victims recover after about three months, 10-20 percent of people who’ve suffered a mild concussion deal with persistent symptoms.
How Is The Procedure Performed
The technologist begins by positioning you on the CT exam table, usually lying flat on your back. They may use straps and pillows to help you maintain the correct position and remain still during the exam.
Many scanners are fast enough to scan children without sedation. In special cases, children who cannot hold still may need sedation. Motion may cause blurring of the images and degrade image quality the same way that it affects photographs.
The exam may use contrast material, depending on the type of exam. If so, it will be swallowed, injected through an intravenous line or, rarely, administered by enema.
Next, the table will move quickly through the scanner to determine the correct starting position for the scans. Then, the table will move slowly through the machine for the actual CT scan. Depending on the type of CT scan, the machine may make several passes.
The technologist may ask you to hold your breath during the scanning. Any motion, including breathing and body movements, can lead to artifacts on the images. This loss of image quality can resemble the blurring seen on a photograph taken of a moving object.
When the exam is complete, the technologist will ask you to wait until they verify that the images are of high enough quality for accurate interpretation by the radiologist.
A CT scan of the head is usually completed within 10 minutes.

UCSF/SFGH Researchers Say Better Diagnosis Would Help Prediction of Outcomes and Guide Treatment
Hospital MRIs may be better at predicting long-term outcomes for people with mild traumatic brain injuries than CT scans, the standard technique for evaluating such injuries in the emergency room, according to a clinical trial led by researchers at UCSF and the San Francisco General Hospital and Trauma Center .
Published this month in the journal Annals of Neurology, the study led by UCSF neuroradiologist Esther Yuh, MD, PhD, followed 135 people treated for mild traumatic brain injuries over the past two years at one of three urban hospitals with level-one trauma centers: SFGH, the University of Pittsburgh Medical Center and University Medical Center Brackenridge in Austin, Texas. The study was called the NIH-funded TRACK-TBI .
All 135 patients with mild traumatic brain injuries received CT scans when they were first admitted, and all were given MRIs about a week later. Most of them had no detectable signs of injury on a CT scan, but more than a quarter who had a normal CT scans also had detectable spots on their MRI scans called focal lesions, which are signs of microscopic bleeding in the brain.
What Happens After A Ct Of The Brain
If contrast media was used during your brain CT scan, you may bemonitored for a period of time to check for any side effects orreactions to the contrast media. Notify your radiologist or if youexperience itching, swelling, rash or difficulty breathing. If younotice any pain, redness and/or swelling at the IV site after youreturn home following your procedure, you should notify your doctor asthis could indicate an infection or other type of reaction.
Otherwise, there is no special type of care required after a CT of thebrain. Most patients are permitted to resume their usual diet andactivities. Your doctor may provide additional or alternateinstructions after the procedure, depending on your particularsituation.

What Are The Different Parts Of The Brain
The brain can be divided into the cerebrum, brainstem, and cerebellum:
Cerebrum. The cerebrum is composed of the right and left hemispheres. Functions of the cerebrum include: initiation of movement, coordination of movement, temperature, touch, vision, hearing, judgment, reasoning, problem solving, emotions, and learning.
Brainstem. The brainstem includes the midbrain, the pons, and the medulla. Functions of this area include: movement of the eyes and mouth, relaying sensory messages , hunger, respirations, consciousness, cardiac function, body temperature, involuntary muscle movements, sneezing, coughing, vomiting, and swallowing.
Cerebellum. The cerebellum is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.
More specifically, other parts of the brain include the following:

How Is A Head Injury Treated
Consider seeking immediate medical attention with any form of head injury as the consequences of unrecognized or inappropriately treated head injury may be potenaatially serious.
Patients with minor head injuries will be observed and treated for symptoms, including pain medication for headache and medications to control nausea and vomiting. If you have symptoms of a simple concussion, you should avoid being overly active. Your physician will advise you as to when you can return to your normal daily routine and sporting activities.
More serious, traumatic brain injuries will require individualized and often emergency care, such as surgery to remove blood clots and relieve pressure on the brain.

Why Mris And Ct Scans Often Miss Traumatic Brain Injuries
We’ve covered the types, symptoms, and treatments for traumatic brain injuries after a wreck or work accident in a previous blog post. Sometimes the signs are obvious, but many times they are not.
Here’s how to find out if you’re suffering from a traumatic brain injury caused by a wreck or work accident and why it’s so important to have an accurate diagnosis.
Only a doctor can identify the extent of your injuries. Brain injuries can alter cognition, behavior, vision, hormones, speech, sleep, blood flow, internal organs, nervous system, and many other bodily functions.
Left untreated, a TBI can lead to neurodegeneration, making it much more likely to develop diseases like Alzheimer’s or Parkinson’s later in life.
Other traumatic brain injuries come with secondary injuries like brainstem issues, inner ear problems, PTSD, and depression.
Getting down these symptoms and diagnosing a TBI is crucial for a personal injury case if you want a fair outcome and settlement. The longer you wait or the more you downplay symptoms, the easier it is for the insurance company to reduce or deny a claim.
Diagnosing brain injuries, however, can be complicated. About 80 percent of TBIs cannot be seen on an MRI or CT scan. The only other way to discover a TBI used to be neuropsychological or psychological testing – a fancy way of saying doctors ask patients questions or give them tasks to complete.

How Should I Prepare
Wear comfortable, loose-fitting clothing to your exam. You may need to change into a gown for the procedure.
Metal objects, including jewelry, eyeglasses, dentures, and hairpins, may affect the CT images. Leave them at home or remove them prior to your exam. Some CT exams will require you to remove hearing aids and removable dental work. Women will need to remove bras containing metal underwire. You may need to remove any piercings, if possible.
Your doctor may instruct you to not eat or drink anything for a few hours before your exam if it will use contrast material. Tell your doctor about all medications you are taking and if you have any allergies. If you have a known allergy to contrast material, your doctor may prescribe medications to reduce the risk of an allergic reaction. To avoid unnecessary delays, contact your doctor well before the date of your exam.
Also tell your doctor about any recent illnesses or other medical conditions and whether you have a history of heart disease, asthma, diabetes, kidney disease, or thyroid problems. Any of these conditions may increase the risk of an adverse effect.
What Is Mri Brain Spectroscopy
MRI spectroscopy compares the levels of different products of metabolism in the tumour with that of the normal brain tissue surrounding it.
The higher the grade, the more quickly a tumour is growing and hence the more energy it needs. The more energy it uses, the higher the levels of these metabolites because they are the end products of the energy cycle in each cell. A healthy brain cell will produce different levels of these metabolites when compared to a tumour cell because it uses energy in a different way, and levels can vary across tumour types as well as grades.
MRI spectroscopy can also be invaluable when assessing if a tumour is actively recurring or whether the image simply shows areas that have died after treatment , which can sometimes be difficult to tell apart just by looking at the images obtained by a standard MRI scan.
What Happens During An Mri
Before the scan, you may need a contrast agent. Sometimes, you will have one scan without the contrast dye followed by an MRI with the dye. Depending on what parts you are having scanned, you may drink the solution or have it injected into a vein. After removing all clothing and jewelry, youll dress in medical scrubs or a hospital gown. Next, youll lie on the scanner table, which slides into the device. You will have earplugs or headphones to wear. The MRI machine makes a lot of noise while running.
During the scanning process, you may be required to hold your breath for specific scans. Even the slight movement of breathing can affect the results. MRIs are painless and last up to an hour, though some may take slightly more time.
