Magnetic Resonance Imaging or MRI scans use magnetic waves to image the various focal areas of the body.
An MRI Scan – an acronym for a Magnetic Resonance Imaging Scan – is a Test process where powerful and controlled magnetic fields, radio waves and computer technology combine to produced highly detailed pictures of the inside of the human body. Since an MRI Scan is usually done on the brain, the procedure or Test is sometimes also simply called a Brain MRI or Cranial MRI. An MRI Scan differs from a CT Scan or X-Ray in that it doesn’t involve the ionizing radiation of X-rays, which is known to sometimes leave behind harmful effects over the long term. The biggest advantage that an MRI Scan has (over, say, the CT Scan or Tomography Scan) is that it produces 3D images instead of 2D images through 3D reconstruction is available now for CT scan also. The extra ‘vision’ and ‘understanding’ this additional dimension of depth offers is invaluable for medical purposes – be it diagnosis or treatment. This makes an MRI Scan highly effective (and unmatched) when it comes to analyzing small structures of the brain, such as, for example, brain stem or the pituitary gland. An MRI Scan usually doesn’t have any risks associated with it.
- Radiation Free Imaging
- Multi-Sequence Details: It stands among the most comprehensive & advanced imaging method, which incorporates can several complicated imaging sequences to best adapt to suit your complaints.
- Soft Tissue Demarcation: MRI offers much better soft tissue demarcation than CT Scan and X-Rays
- No Side-Effects: No significant side-effects of magnetic imaging.
Cost for MRI Scan
MRI Scan costs depend on various factors such as the consumables, number of films, time involved. Please search below to find the cost and details for your MRI tests. Please note: If your doctor's prescription specifically mentions "CEMRI" or "Contrast", it implies that your require Contrast Enhanced MRI Scan / MRI Scan with Contrast. Such a scan may require additionally preparation and a Creatinine test, before MRI contrast is administered.
What is an MRI Scan with Contrast?
While an MRI Scan will generate clear images of ‘dense organs and structures’ (ie, those with a high density), substances with a low density can turn out hazy and hard to detect. To make the latter more clearly visible, the patient may be administered a special ‘dye’ - technically referred to as a ‘Contrast Material’ - via injection (done to make the liver, gall bladder, urinary tract or blood vessels stand out sharper in the Scan results), orally (to enhance images of the digestive tract) or via Enema (this refers to instances when greater clarity is required for the intestines, and the Contrast Material is inserted through the rectum). To help the kidneys remove the Contrast Material after the procedure is over, one may be advised to drink a lot of fluid.
3 Tesla MRI -or- 1.5 Tesla MRI (1.5T MRI vs 3T MRI)
Tesla is the unit of measurement for measuring magnetic strength. 3T MRI Machines and their price are the more expensive and provide for better clarity in imaging.
To understand in layman's terms, you may consider the comparison between a 3.0 Tesla MRI vs a 1.5 Tesla MRI to be that of a 10 Megapixel Camera Photo vs 5 Megapixel Camera Photo.
Most MRI Scan centres in Delhi/NCR use 1.5 Tesla MRI Machines. Several leading hospitals such as Indraprastha Apollo Hospital, Medanta Medicity, and Sir Ganga Ram Hospital, use 3.0 Tesla MRI Machines for MRI scan in Delhi. Please search above MRI test cost or MRI scan rate in Delhi NCR, India
MRI Appointments, Duration & Waiting
MRI Scans at House of Diagnostics are offered on a first come-first serve basis. Often, as the factors listed below may change from one study to the next, getting a MRI scan often involves a waiting time, as the exact length of your procedure and that of the patients before you, often also depends on the patient's conditions and cooperation.
If your question is how long should an MRI take, Please note that several factors can together determine the time required for MRI Scan.
- Procedure: Depending on procedure, MRI Scan time may vary - a routine MRI Brain should typically be completed in less than 15 minutes, where as a MRI Multiparametric Prostate with Contrast may require over 60 minutes of MRI planning and sequences.
- Patient Movement: If a patient is unable to lie straight and moves during the MRI procedure and moves during the prcedure, it may warrant for restart in partial sequences which could cause the time for the MRI to be extended from, say 15 minutes to even 40 minutes.
- Patient-Specific Detailing: Frequently, if findings in the study require additional detailing, the technician in charge may observe and conduct a few additional minutes of detailing to better help the doctors detail the findings of the case.
Some MRI test require contrast. A contrast is a substance used to increase the fluids within the body in medical imaging. You will feel no ill effects from the injection.
Your doctor has chosen to use intravenous contrast for your examination after considering the risks and benefit to you. Contrast is a clear fluid usually injected into a vein in the arm immediately before the scan.
Magnetic resonance imaging (MRI) is very safe and most people are able to have the procedure. However, in some circumstances, an MRI scan may not be recommended.
Please tell the MRI department if you have or think you have any metal in your body or if you are pregnant.
Although there are no known effects, it is advisable not to scan pregnant women.
However, in certain critical cases, it may be necessary to be scanned during pregnancy when a more invasive diagnostic test would otherwise have to be performed. Please consult your doctor before getting a scan done.
