Radiology
Sat Aug 10 2024
As far as medical diagnostic tests go, MRI and CT Scans are pretty common recommendations made by doctors and seamlessly accepted by patients. Both of the procedures are painless on the surface and any branch of Manipal TRUtest Near You can guide and assist you through such tests. CT Scans and MRIs are very similar in their purpose of taking pictures of internal organs, skeletal structures, and other things.
Even though MRIs have a few things in common, the differences are more glaring and to understand the whole thing in and out, it is crucial that we start by discussing each process in detail, so there remains nothing hidden or out of sight. At Manipal TRUtest Lab, you will be met with compassion and proper supervision, whether you are taking an MRI test or a CT scan.
MRI Oversight
The name magnetic resonance imaging itself tells a lot about the device and how it operates. As the name suggests, the two main components used in the MRI device are magnets and radio waves and they are the prime elements for crafting 3D images of the patient's body. MRIs are performed on various parts of the human body depending on where the issue lies and Manipal TRUtest Laboratories can assist you in any way possible.
MRI scans have been proven to provide more clearer and accurate imaging, making it easier for doctors to identify the problematic parts of your body and immediately act upon them. When conducting an MRI scan, the patient is asked to lie down on a stretcher bed which is attached to the machine and gradually slides inside the circular opening of the machine where the images are captured.
As the machine is powered up, it will start making a loud noise. Manipal TRUtest supervisors will provide earbuds or plugs which will dissuade the noises. The time it takes to get the MRI scan conducted usually is 15mins but it takes up to an hour based on your medical requirements. The patient may also be asked to take a contrast agent, if the doctor says so, further improving the image quality.
CT Scan Oversight
In the case of a CT scan, also known as Computer Tomography, a diagnostic imaging procedure, the machine uses specialized X-rays with mild radiation with the purpose of producing slices with a clear view of internal body structures. The Manipal TRUtest Lab performs each diagnostic test under the strict supervision and monitoring of technicians and doctors.
The X-ray slices captured by the CT scan device are then placed on a computer to implement 3D imaging. The scan result reveals much greater insight into the body and helps make a diagnosis and prepare for treatment plans. Much like MRIs, the CT scan machine also has a donut-like, circular opening and the patient has to lie down on a stretcher which is then entered inside the machine.
The Elemental Differences Between CT Scan & MRI
| MRI | CT Scan |
| It uses radio waves and magnets to procure 3D imaging. | A CT scan uses X-ray radiation and computers to acquire an image. |
| MRI scans offer clearer imaging options. | The CT scan images are not as clear as the MRI scan. |
| It costs much more than a CT scan. | CT scans are easily affordable. |
Final Wrap
At Manipal Labs, the technicians will make sure that the machine is in good health before the patient is brought to the room. Once the patient is settled, the scanner starts rotating around the patient's body producing a slice in each cycle. It takes only a matter of minutes for the CT scan to be completed and the patient can walk back home without any problem.

Everything You Should Know About Head MRI and Cost
Magnetic Resonance Imaging (MRI) is a powerful diagnostic tool that helps medical professionals visualize the internal structures of the body in detail. A Head MRI is a non-invasive imaging procedure that creates detailed images of the brain, skull, blood vessels, and surrounding tissues. It is widely used to detect and evaluate various neurological conditions, injuries, and abnormalities.
What is a Head MRI?
A Head MRI uses strong magnetic fields and radio waves to generate images of the brain and other structures inside the head. Unlike X-rays or CT scans, it does not involve ionizing radiation, making it safer, especially for repeated use. The procedure usually takes around 30 to 60 minutes and may involve the use of contrast dye (gadolinium) to enhance the visibility of certain areas.
Why is a Head MRI Recommended?
Doctors recommend a head MRI for various reasons, including:
- Persistent Headaches or Migraines: To rule out underlying neurological causes.
- Seizures: To identify any abnormalities in the brain tissue.
- Stroke Symptoms: To detect signs of stroke or mini-strokes (TIAs).
- Traumatic Brain Injury: To assess the extent of damage following an accident or injury.
- Brain Tumors: To locate and evaluate tumors or cysts.
- Multiple Sclerosis (MS): To detect and monitor lesions or inflammation in the brain.
- Infections: Such as encephalitis or meningitis.
- Dizziness or Vision Problems: When symptoms point to a neurological cause.
How is a Head MRI Performed?
The patient lies on a movable table that slides into the MRI scanner a large, cylindrical machine. During the scan, it is crucial to stay still to obtain clear images. The procedure is painless, although the machine may make loud thumping or tapping sounds. Patients with claustrophobia may be given a mild sedative. If contrast is required, it is injected through a vein in the arm before or during the scan.
Safety Considerations
While MRIs are generally safe, they are not suitable for everyone. Individuals with pacemakers, metal implants, or certain other medical devices may not be eligible for an MRI. It’s essential to inform the radiologist about any medical conditions, allergies, or pregnancy before the procedure.
Cost of a Head MRI in India
The cost of a head MRI can vary significantly based on location, the type of facility (private vs. public), and whether contrast dye is used. Some factors influencing the cost include:
- City or Region: Tier 1 cities usually have higher costs.
- Hospital or Diagnostic Center: Premium centers may charge more.
- Type of MRI Machine: High-resolution 3 Tesla MRIs may cost more than standard 1.5 Tesla machines.
- Insurance Coverage: Some health insurance policies cover the cost of diagnostic tests, including MRIs.
A Head MRI is an invaluable tool in modern medicine, offering detailed insights into the brain and related structures. While the procedure is safe and non-invasive, it should only be performed upon a doctor’s recommendation. Knowing the approximate cost and process helps patients make informed decisions about their health and diagnostics.
If you are experiencing symptoms such as persistent headaches, memory loss, or neurological changes, consult your healthcare provider. Timely imaging can lead to early diagnosis and better treatment outcomes.

What Makes MRI Scans So Valuable?
Unlike X-rays or CT scans, MRI provides highly detailed pictures of soft tissues, organs, and even the nervous system. It is especially useful in detecting issues in the brain, spine, joints, heart, and internal organs. When symptoms are unclear, an MRI can uncover hidden problems that other scans might miss. This makes it a trusted choice for doctors who want a clearer view of what’s happening inside the body.
At Manipal TRUtest, advanced MRI services ensure that patients get accurate and reliable results quickly, helping them start treatment without unnecessary delays.
Common Health Issues Detected by MRI
MRI scans are used to diagnose a wide range of conditions, such as:
- Brain and spinal cord issues: MRI is excellent at detecting brain tumors, strokes, multiple sclerosis, and spinal cord injuries.
- Joint problems: If you have unexplained joint pain, an MRI can show damage to ligaments, cartilage, and muscles.
- Heart conditions: Doctors use MRI to assess the structure and function of the heart, helping to diagnose heart diseases early.
- Organ health: MRI scans can spot liver diseases, kidney problems, and abnormalities in other internal organs.
By offering clear images, MRI helps in creating the right treatment plan, making recovery faster and smoother.
When Should You Consider an MRI?
Doctors usually recommend an MRI when they need a deeper understanding of a health issue. You may need an MRI if:
- There is a need to monitor known conditions like tumors or injuries.
- You experience unexplained symptoms that cannot be diagnosed with other imaging tests.
- You have persistent headaches, seizures, or dizziness.
- You are suffering from chronic joint or back pain.
Choosing a trusted center like Manipal TRUtest for your MRI scan ensures that you are in safe hands, receiving quality care at every step.

When and Why You Might Need an Abdominal Scan
The abdomen is where important organs such as the liver, kidneys, pancreas, gallbladder, and intestines all reside. When something doesn't feel right in this area, doctors often recommend an abdominal scan to figure out what is going on inside the abdomen. These scans are safe, quick, and can help provide important information for the next step in your path to better health.
What is an Abdominal Scan?
An abdominal scan is an imaging test that allows doctors to view organs and tissues inside the belly. It can be done by different procedures such as ultrasound, CT scan and MRI. Each technique has its own benefits, depending on what the doctor is looking for. The scans are quick and painless, and can sometimes identify problems early on before they have developed into symptoms.
When Might You Need an Abdominal Scan?
There are many reasons a doctor might recommend an abdominal scan. Some of the most common situations include:
1. Unexplained Pain
If you are experiencing pain in your abdomen that does not go away, a scan can help identify the cause. It could be due to gallstones, liver issues, infections or kidney stones,
2. Digestive Problems
Persistent issues like nausea, vomiting , and changes in bowel habits may require a closer look. An abdominal scan can reveal if there are any blockages, swelling, orabnormalities in the digestive organs.
3. Injury or Trauma
After an accident or a fall, an abdominal scan is often done to check for internal bleeding and organ damage. Even if there are no external injuries, it is important to ensure that the internal organs are safe.
4. Suspected Infections
Infections in the abdomen, such as a reddened appendix or an abscess, which can be dangerous if not treated quickly. A scan helps detect these circumstances so that the right treatment can begin without delay.
