What Can You Learn From CT Scan Of Your Brain?

CT scan or computed tomography is an imaging technique that uses rotating X-Rays to generate images of parts of body. CT scan creates creates cross sectional views of parts of the organ by taking 2D images of slices of that organ.
CT scanner converts these images into a 3D view with the help of a computerised machine.

CT Scan Brain
The 3D view of cross sections of parts of organ help doctors to study the details about a tumor, brain stroke, vascular condition and other related diseases that can affect brain or head.

Brain Tumor Symptoms – Brain MRI

When we talk of of brain tumor symptoms, there may no symptoms or there may be symptoms such as severe headaches, blurred, loss of vision and much more.

Symptoms depend of various factors such as the location of tumor, organs it has effected, in what stage is the tumor.

Blurred vision may be due to the location of tumor near some optical nerve. Similarly problem is speech can be due to a tumor close to related nerve.

Various brain MRI scans and other examinations may be needed to diagnose exact condition of the tumor.

Sometimes there are other symptoms as well. Some specific tumor location can lead to change in personality as well .

A tumor in the base of brain can lead to hormonal disorders because that is the place where all hormonal development takes place.

If you are experiencing any of these symptoms, you should get them tested as soon as possible. to avoid any severe life threatening conditions.

MRI scans play very important role in examining all these symptoms and giving a detailed report.

 

Magnetic Resonance Angiography – Resonance Imaging

Magnetic Resonance Imaging and Magnetic Resonance Angiography (MRA) both use strong magnetic field to create images. The difference in two technologies is that —

(1) MRA comparatively is a newer technology than MRI

(2) MRI is used to examine bones, joints, soft tissues, internal organs etc whereas MRA is used to examine health of blood vessels and arteries.

(3) Angiography can be performed using X Ray and CT scan also but magnetic resonance angiography is recommended because it gives better results and it is non invasive. Doctor may ask for fluid intake to create better contrast images.

(4) Preparations for both MRI and MRA are almost same. You should ask the radiology expert and doctor about any special preparations in case if you are pregnant or any medication is going on.

(5) MRA can detect blockages in blood vessels while MRI cannot.

3H Care offers MRA with it’s partner labs at discounted price. You can compare price in different nearby labs by using comparison feature.

How is a CT scan different from MRI?

With the advancement in technology, modern medicine has advanced beyond x-rays. The most widely used tests besides x-rays are Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI). But it is quite natural to get confused between two because in both the cross-sectional pictures of the body is shown but the procedure and technique to carry this out is where the difference lies. In both of them the patient is made to rest on a table that slides through the middle of the machine to obtain images of a particular body part. Read on to know the tale of two scans

Computed Tomography (CT) Scan

CT scan uses rotating x-rays to obtain images of the desired body part. In this type of scan the x-ray tube spin around the person placed on the table and the x-ray detector is placed on the exact opposite side of the patient.

A CT Scan can provide complete information about the body, including the chest (lungs and heart), head (inner ear, eyes, brain and its vessels), skeletal system (spine, shoulders and neck), bladder, pelvis and hips, gastrointestinal tract, reproductive system. This scan is commonly used in emergencies as this scan does not take much time and the whole procedure generally takes fewer than 5 minutes.

Magnetic Resonance Imaging (MRI)

Unlike CT scan in which x-rays is used, MRI Scan uses radio frequency pulses and powerful magnetic fields. This scan produces detailed and complete images of body parts and organs. MRI Scan is best suited for producing detailed pictures of tendon tissues and examining soft tissues in ligament, brain tumor etc. The cost of MRI scan is generally more than that of CT scan.
