An MRI motorcar uses a magnetic field to produce detailed images of the brain, spine, heart, bones, and other tissue. About modern MRI centers can requite yous a copy of your MRI on a disc or wink drive subsequently your engagement. While only your doctor can make a diagnosis based on the image, viewing and analyzing your MRI at home is easy!

1. i

   Insert your MRI disc into your estimator. Today, you will usually be given a disc with your images on it after your MRI. The main purpose of this is so that you lot can give the disc to your medico, but there's aught wrong with reading your MRI at dwelling house. Start by putting the disc into your calculator'southward DVD drive.

   • Note: Some MRI centers may have different policies for giving patients copies of their MRI. For instance, instead of a disc, you lot may be given a USB drive. It's even possible to host and send MRI files online. The important thing in any case is to get the MRI files onto your computer.^[1]

2. ii

   If the program loads automatically, follow the on-screen prompts. If you're lucky, the program will automatically load when yous put the disc into your figurer. In this case, simply follow the instructions on screen to install and access the program. Usually, you'll want to use the default option (or "Yep," "OK," etc.) or every prompt you are given.^[2]

   • However, MRI viewing software is notoriously unreliable — it's something that even doctors take a hard time with. You may need to have extra action (see beneath).

   If necessary, install the viewing software. If the software doesn't load automatically, nigh MRI discs volition come up with some way to install it on the disc. In general, you'll need to open the disc to explore the files, find this installation programme, and run it. The verbal steps you need to take will vary depending on how your MRI center has packaged your images on the disc.

   • If yous're non having whatsoever luck or you can't find an included installer program, endeavor downloading a free MRI viewer from the internet. This site has many links to programs that tin view medical images in the standard DICOM format.^[three]

4. iv

   Load the report. Again, the exact steps you lot'll demand to have here tin vary slightly depending on the verbal programme yous have packaged with your images. Generally, most MRI viewers volition take some sort of option to load or import images that you can select from the card bar at the top of the screen. In this case, select this option, then pick the image file on your disc that you'd like to await at.

   • Notation that most medical imaging software refers to collections of images as "studies". You may not run into an "import image" option, just you'll probably run across something to the event of "import study."
   • Another option you may meet is that, every bit soon every bit the program loads, it will nowadays you with a "table of contents" of all the MRIs on the disc. In this case, simply select the written report you want to view first to proceed.

5. 5

   View the images. Most MRI programs showtime with a large black space on one side of the screen and a smaller toolbar on the other side. If yous see small preview pictures of your MRI images in the toolbar, double click on the image you desire to view. It should load a big version of the image into the black area.

   • Be patient while y'all expect for your images to load. Though the viewing programs don't unremarkably look similar much, a single MRI epitome contains a large corporeality of data, so information technology may accept your estimator a moment or two to terminate the chore of loading it up.

   Familiarize yourself with the different MRI viewing schemes. When your MRI beginning loads upwardly, if yous're lucky, it will be immediately obvious what you're looking at. However, in many cases, the paradigm you see may be a completely unintelligible mix of black, white, and grey. Knowing how MRIs are shot tin help you brand sense of your images. The iii main means MRIs are displayed are:^[four]

   • Sagittal: Often the easiest for non-doctors to interpret. Sagittal MRIs are basically side or profile views of your body. The prototype is as if you've been sliced in half vertically, from your head to your pelvis.
   • Coronal: These images are basically a "head on" view of your body. You lot're looking at your features vertically from the front — as if you were continuing facing the photographic camera.
   • Cross-exclusive: Often the hardest for non-doctors to translate. Here, yous're basically viewing thin slices of your torso from the top down — as if y'all've been cut into many thin horizontal slices from your head to your toes like a salami.

2. 2

   Look for contrast to identify dissimilar body features. MRIs are in black and white, which can sometimes go far hard to tell parts of the body apart. Considering at that place's no color, contrast is your best friend. Luckily, different types of tissue evidence up as unlike shades on an MRI, so it'due south easy to see dissimilarity where differing tissues encounter.^[v]

   • The verbal shade that each blazon of tissue will be depends on the MRI's contrast settings. The 2 main dissimilarity settings are chosen T1 and T2. Though the differences betwixt these settings are minor, they tin can help doctors observe bug more efficiently. For instance, T2 is usually used for diseases (as opposed to injuries) because diseased tissues tend to testify upwards better on this setting.

3. 3

   Pick an appealing series layout. MRI programs near always have the ability to brandish more than i image at one time. This makes it convenient for doctors to compare dissimilar views of the same expanse or fifty-fifty MRIs taken at different times. For most not-doctors, it's easiest to simply choose a one-image-at-a-fourth dimension layout and wheel through the images individually. Nevertheless, in that location should be onscreen instructions to show ii, four, or many more images at once, so experience gratuitous to play around with this feature.

4. four

   Apply the section-cut line to meet where cross-sections are located. If you display a cross-sectional prototype along with a sagittal or coronal image, you may see a section-cutting line on the second paradigm. This will exist a directly line running through the image, just it may not be present on all MRIs. If your image does have one, this shows where on the 2nd image the cross department is located. You should exist able to move the section cut line toward the eye, right or left of the prototype. This will modify the larger layout image to show the torso from the new direction of the scan.

   • The section-cutting line on the layout picture as well shows the direction that the image was taken from. For example, if your MRI were a picture of an everyday object, like a tree, the section cut line might show you if the picture was taken from above in a plane, from a second-story window, or from the basis.

5. v

   Drag the section-cut line to view new parts of the study. Dragging the section-cut line to a dissimilar role of the epitome allows you to "move around" your MRI images. The image should modify your view to the new area automatically.

   • For example, if you're viewing a sagittal image of your spine along with a cross department of one of your vertebrae, moving the section-cut line may allow you to cycle up and down through the various vertebrae above and below information technology. This can be useful for locating problems like herniated discs.

   Await for non-symmetrical patches. More often than not, the body is very symmetrical. If, in your MRI, you lot discover a patch of lightness or darkness on one side of your body that does not match what's on the other side, this tin be cause for concern. Similarly, for parts of the body that have many similar features repeated multiple times, a departure in one of the features can be a sign that something is amiss.

   • A adept case of the second example is for spinal disc herniations.^[six] The spine is fabricated upwards of many dissimilar bone vertebrae stacked on top of each other. Between every two vertebrae is a fluid-filled disc. When yous get a herniated disc, one of these discs breaks and the fluid leaks out, causing pain as it presses confronting the nerves in your spine. You'll be able to encounter this on a spinal MRI — at that place will be a long line of "normal" vertebrae and discs, with one noticeably bulging out.

2. 2

   Examine the structure of the vertebrae for spinal MRIs. MRIs of the spine are typically some of the easiest for not-doctors to read (especially in sagittal view). Expect for noticeable misalignments in the vertebrae or fluid discs. Having just ane of either be out of alignment (as in the instance higher up) tin exist the source of serious pain.

   • Behind the spinal vertebrae, in sagittal view, you'll see a white, rope-like structure. This is the spinal cord, the construction connected to all the trunk's fretfulness. Expect for spots where the vertebrae or discs seem to "pinch" or press into the spinal cord — because the nerves are so sensitive, only a little pressure tin atomic number 82 to hurting.

3. three

   Use cross-sectional views to spot abnormalities in encephalon MRIs. MRIs of the brain tissue are oftentimes used to bank check for brain tumors, abscesses, and other serious problems that can bear upon the brain. The easiest style to see these things is commonly to choose the cross-exclusive view, so descend slowly from the top of the head downwards. Y'all're looking for anything that'south not symmetrical — a dark or light patch that's on one side but not the other is cause for business.

   • Brain tumors often take the class of round, golf brawl-like growths in the encephalon which will usually bear witness up as either brilliant white or slow gray surrounded by a ring of white. Nevertheless, other brain problems (like multiple scleroses) tin also have a whitish appearance, so this lonely may not exist a sign of a brain tumor.

4. 4

   For knee MRIs, wait for inconsistencies between the two knees. Comparison coronal views of an injured knee with those of a healthy articulatio genus can make it easy to spot problems. A few of the issues you may desire to expect out for include:^[7]

   • Osteoarthritis: Decreased articulation space in the afflicted knee. Germination of osteophytes (jagged boney projections the course off the side of the affected knee).^[8]
   • Ligament tear: Increased joint space in the affected knee. Pocket may make full with fluid that shows upwards every bit white or light-colored. Separation of the ligament itself may be visible.^[9]
   • Meniscus tear: Aberrant joint spacing. Nighttime-colored features on either side of the joint infinite pointing inward.^[10]

5. v

   Never diagnose yourself from your MRI images. This bears repeating: if you run into something that you're not certain most on MRI, don't assume that y'all have a terrible illness without talking to your doctor. Conversely, if you don't notice anything out of the ordinary on your MRI, don't assume yous're fine without talking to your md. Ordinary people don't have the knowledge and grooming to make accurate diagnoses, so, when in dubiousness, ever become the advice of a medical professional.
