Vardhman Hospital has installed the most advanced First 32 Channel MRI Machine in Muzaffarnagar Brivo Inspire 355 from GE with dedicated coils for different body parts. The last 30 years has seen many changes in the MRI technology. From 0.2 Tesla machine using permanent magnet the technology reached 3 Tesla using superconducting magnet. The medical device manufacturing companies like GE, Toshiba, Siemens, Philips and Hitachi were all working in one direction, increase the magnetic strength to get better quality of images. In 1998 when 3 Tesla MRI was launched it was expected to give very high quality images. The quality of image depends upon signal to noise ratio. In MRI study, signal means the magnetic strength and noise is the unnecessary information that the body gives. When a very powerful magnetic fied of 3 Tesla was created the body started giving too much unnecessary information thereby increasing the noise. This meant that Signal to Noise ration in a 3 Tesla machine was poor thereby compromising the image quality.
32 Channel Machine
Another revolutionary development which took place in MRI technology was 360 degree imaging. So far CT Scan was doing 360 degree imaging but MRI was only doing 180 degree scanning. Whenever the patient would lie on the MRI table, a coil was put on top of the body part which was to be scanned. The MRI machine at Vardhman Hospital is the first machine which has a coil embedded in the table. Now the data sent from the body is captured by coil below and the coil on top. This technology is highly useful in Brain and Spine MRI.
Now Digitizer Is Inside The Magnet
The actual problem was in a different area - Human body gives analog signals which are captured by the coils and transmitted to a digitizer located almost 12 feet away. The digitizer could not be kept in the MRI room because as soon as the data is digitized, it is stored on magnetic medium which was not possible to be kept in the MRI room due to strong magnetic field. Since analog signal loses intensity with distance the need was to create a strong signal meaning higher magnetic field. In 2014 a new technology was developed whereby the digitizer after converting the analog signal to digital did not store it on magnetic medium but on optical cable. This brought the digitizer into the MRI room and now it is located just 4 cms away from the Magnetic coil. Thus the need to create 3 Tesla Magnetic field has become redundant and now the best MRI machines are coming with 1.5 Tesla Magnetic strength which gives very good Signal to Noise ratio.
Tests Done On MRI
While most of the MRI machines in UP are either 4 channel or 8 channel, the MRI machine at Vardhman Hospital is 32 Channel which gives crystal clear images of all the body parts.
The 32 Channel MRI machine which is considered the most advanced and best MRI machine available in Muzaffarnagar UP is capable of performing imaging for all body parts with utmost precision. Following are areas where MRI is considered the gold standard
Brain & Spine MRI
Comprehensive head and spine examinations can be performed with dedicated programs. customized presets for fast scanning . The Neuro Suite also includes protocols for diffusion imaging, perfusion Neurology imaging, and Functional MRI. The MRI of spine lets your doctor examine the small bones, called vertebrae, which make up your spinal column, as well as the spinal disks, spinal canal, and spinal cord. MRI scans of the spine are needed when conservative treatment is not working and more aggressive back pain treatments (e.g. spinal injections or surgery) are contemplated to relieve the symptoms.
Excellent MR Angiography can be performed to visualize arteries and veins with or without contrast agent. MRI Angiography is especially useful in identifying abnormalities such as aneurysms, blockage in carotid artery which can cause brain stroke, identifying arteries in the legs for endovascular surgery, very helpful in kideny transplant and diagnosing pulmonary embolism. The 32 Channel MRI at Vardhman Hospital is one of the best machines available in Muzaffarnagar for performing MRI Angiography. The Non Contrast MR Angiography is extremely useful in patients with deranged Kidney Function.
Cardiac MRI creates both still and moving pictures of your heart and major blood vessels. Doctors use cardiac MRI to get pictures of the beating heart and to look at its structure and function. These pictures can help them decide the best way to treat people who have heart problems. Cardiac MRI is also used for the patients who have kidney problems and cannot take contrast or dyes with iodine. Cardiac MRI is very common non invasive test for diagnosing damage caused to the heart muscle due to heart attack, pericarditis ( where the sack around the heart membrane is inflamed).
Whole Body MRI
The 32 Channel MRI at Vardhman Hospital, Muzaffarnagar, has faciity of Whole Body MRI. Vardhman Hospital, Muzaffarnagar has 6 dedicated coils with MRI machine to take care of the whole body imaging. When 3 Tesla MRI came the body imaging was the biggest casualty as the Signal to Noise Ratio was very high and therefore the doctors preferred CT Scan of the Abdomen over MRI but in the latest 360 degree MRI this problem has been overcome and now the MR Imaging of the abdomen has become the preferred diagnostic modality for GI Surgeons and Physicians
MRI at Vardhman Hospital, Muzaffarnagar has dedicated breast coil for better and descriptive results. Cases especially related to breast cancer are visualized better through MR Mammography. Also MRI pelvis in cases of uterine fibroids is very usefull in determining the size and the location of the fibroids enabling the gynaecologist to plan the surgery for best outcomes. Excellent soft tissue differentiation, customized protocols (e.g. with fat saturation or water excitation or silicone excitation), as well as flexible multiplanar visualization allow for fast, simple and reproducible evaluation of MR breast examinations.
The patient will have to fill out a screening form asking about anything that might create a health risk or interfere with imaging. Below is a list of items that can create a health hazard during an MRI Scan.
Implantable cardioverter defibrillator (ICD)
Implanted drug infusion device
Patient Preparation For MRI
Thereís no special preparation necessary for the MRI examination. Unless the staff at Vardhman Hospital specifically requests that you are not to eat or drink anything before the exam, there are no food or drink restrictions. You should continue to take any medication prescribed by your doctor unless otherwise directed. It is not allowed to wear anything metallic during the MRI examination at Vardhman Hospital, Muzaffarnagar, so it would be best to leave watches, jewellery or anything made from metal at home. Even some cosmetics contain small amounts of metals, so it is best to not wear make-up. At Vardhman Hospital, we have a safe place to lock up valuables if you canít leave them at home.
Foreign metal objects, especially if in or near the eye
Shrapnel or bullet wounds
Permanent cosmetics or tattoos
Dentures/teeth with magnetic keepers
Other implants that involve magnets
Medication patch (i.e., transdermal patch) that contains metal foil
