Can brain MRI detect brain hemorrhage?


Hemorrhagic stroke is a type of stroke that is caused by an artery in the brain bursting and causing localized bleeding in the surrounding tissues. This bleeding kills brain cells. Hemorrhage literally means "blood coming out." A brain hemorrhage is also known as a brain haemorrhage, an intracerebral hemorrhage, or an intracerebral hemorrhage.

1. What is an MRI?


Brain magnetic resonance imaging (MRI) is a safe and painless method that uses a magnetic field and radio waves to create detailed images of the brain and brain stem. An MRI is different from a CT scan (also called a CT scan or axial computed tomography) because it doesn't use radiation.
An MRI scanner consists of a large donut-shaped magnet that usually has a tunnel in the center. The patient is placed on a table that slides into the tunnel. Some centers have open MRI machines that have larger openings and are helpful for patients with claustrophobia. MRI machines are located in hospitals and radiology centers.

2. The importance of brain MRI


MRI can detect many conditions of the brain such as cysts, tumors, bleeding, swelling, structural and developmental abnormalities, infections, inflammation or problems with blood vessels. It can determine if the shunt is working and detect brain damage caused by an injury or stroke.
Brain MRI can be helpful in evaluating problems such as persistent headaches, dizziness, weakness and blurred vision or seizures, and it can help detect some chronic diseases of the nervous system, such as such as multiple sclerosis.
In some cases, an MRI can provide clear images of parts of the brain that cannot be seen with an X-ray, CAT scan, or ultrasound, which is especially valuable in diagnosing problems. problems with the pituitary gland and brain stem.

3. What is a brain hemorrhage?


A brain hemorrhage is bleeding in or around the brain. It is a form of stroke. Causes of brain hemorrhage include high blood pressure (hypertension), weak or abnormally dilated blood vessels (aneurysms) that leak, drug abuse, and trauma. Many people with a brain hemorrhage have symptoms as if they were having a stroke and may have weakness on one side of the body, difficulty speaking, or a feeling of numbness. Difficulty performing usual activities, including problems with walking or even falling, are not uncommon symptoms. About 13% of strokes are hemorrhagic strokes, or from bleeding into the brain.
A brain hemorrhage is usually marked according to the exact location it occurs in the brain. In general, bleeding anywhere inside the skull is called an intracranial hemorrhage. Bleeding in the brain is called an intracerebral hemorrhage. Bleeding can also occur between the covering of the brain and the brain tissue itself, known as a subarachnoid hemorrhage. If a blood clot occurs between the skull and the brain, it is called a subdural or epidural hematoma depending on whether it is below or above the dura (dural) layer of the brain. Subdural and epidural hematomas are more likely to occur as a result of traumatic brain injury or after a fall and will not be discussed in detail here.
It is important to realize that when bleeding occurs in the brain itself, a headache may not occur, because our brain is incapable of sensing the disturbance that is taking place. However, the covering of the brain (meninges) is extremely sensitive, and if bleeding occurs there, as when an aneurysm ruptures, a sudden and severe headache is a common stroke symptom.

4. What causes brain hemorrhage?


Head trauma: This is a common cause of brain bleeding in people under the age of 50; High blood pressure: This chronic condition, over a long period of time, can weaken the walls of blood vessels. Untreated high blood pressure is a major preventable cause of cerebral hemorrhage; Aneurysm: This is a weakening of the bulging blood vessel wall. It can rupture and bleed to the brain, leading to a stroke; Vascular abnormalities: (Arteriovenous malformations) weakening of the blood vessels in and around the brain that can be present at birth and is only diagnosed if symptoms develop; Amyloid vascular disease: This is an abnormality of the blood vessel walls, which sometimes occurs with aging and high blood pressure. It can cause a lot of small, unnoticed bleeding before causing a large one; Blood or bleeding disorder: Hemophilia and sickle cell anemia can both contribute to low blood platelets and clotting. Blood thinners are also a risk factor; Liver disease.: This condition is associated with increased bleeding in general. Brain tumors .

5. Symptoms of brain hemorrhage


Symptoms of a brain hemorrhage can vary. They depend on the site of the bleeding, the severity of the blood, and the amount of tissue affected. Symptoms tend to develop suddenly. They can get heavier.
If you have any of the following, you may have a brain hemorrhage. This is a life-threatening condition get to the emergency room immediately. Symptoms include:
Sudden severe headache; Epilepsy without a history of epilepsy; Weakness in the arms or legs; Nausea or vomiting; Decreased alertness; coma ; Changes in vision; Loss of fine motor skills, such as hand tremors; Abnormal sense of taste; Loss of consciousness. Keep in mind that many of these symptoms are often caused by conditions other than bleeding in the brain.

6. Diagnosis and treatment of cerebral hemorrhage


6.1. Diagnosis of intracerebral hemorrhage by MRI Based on typical clinical features and symptoms, and progressive worsening of symptoms, clinical diagnosis of intracerebral hemorrhage is made.
Imaging with cranial MRI is essential to confirm the diagnosis of cerebral hemorrhage and to rule out ischemic stroke... MRI is both considered as the first imaging option in assessment and emergency diagnosis of cerebral hemorrhage.
6.2. How to treat cerebral hemorrhage? After you see your doctor, they can determine which part of your brain is affected based on your symptoms;
Doctors may conduct many different types of imaging tests, such as a CT scan, which can detect internal bleeding or blood accumulation, or an MRI scan;
Treatment of bleeding in the brain depends on the location, cause and extent of the bleeding. Surgery may be needed to reduce swelling and stop bleeding. Certain medications may also be prescribed. These include pain relievers, corticosteroids or osmotic drugs to reduce swelling, and anticonvulsants to control seizures.
Patients need to go to a reputable hospital to conduct examination and treatment as soon as there are signs of brain hemorrhage. Currently, Vinmec International General Hospital is one of the leading prestigious hospitals in the country, trusted by a large number of patients for medical examination and treatment. Not only the physical system, modern equipment: 6 ultrasound rooms, 4 DR X-ray rooms (1 full-axis machine, 1 light machine, 1 general machine and 1 mammography machine) , 2 DR portable X-ray machines, 2 multi-row CT scanner rooms (1 128 rows and 1 16 arrays), 2 Magnetic resonance imaging rooms (1 3 Tesla and 1 1.5 Tesla), 1 room for 2 levels of interventional angiography and 1 room to measure bone mineral density.... Vinmec is also the place to gather a team of experienced doctors and nurses who will greatly assist in diagnosis and detection. early signs of abnormality in the patient's body.
