For Project 4 there are two elements that I believe I need to understand that are pivotal in creating a proper animation that would fit the brief and actually be useful in its purpose; that is understanding MRIs (what they do, how you are supposed to act in them, etc), and also understanding what it takes to create something that will appeal to children within my target audience that will be entertaining and also informative. The findings posted below are for the most part entirely taken from the websites I found them, with text that stands out to me and I believe will help being highlighted in bold.
Colour has the ability to inspire, excite, soothe, heal and even agitate. This is particularly true for children, who can be extra sensitive to colour’s impact. So the importance of picking out just the right colour for a young child’s room shouldn’t be underestimated.
While scientists have learned a lot about the way colour influences our minds and bodies, keep in mind that every child is different; these generalisations don’t apply to all. But if you’re curious about how to bring colour into your child’s room, this information from The Complete Book of Color by Suzy Chiazzar can help you get started.
What Is It?
MRI stands for Magnetic Resonance Imaging
The day of the scan
When you arrive at the hospital, you should report to the MRI department. Some scans need additional preparation – information about whether your child needs any additional preparation is in your appointment letter. Your appointment time is 30 minutes before the scan is scheduled. We need this time to prepare you and your child, for instance, completing the metal check described below and to apply some local anaesthetic cream in case your child needs an injection.
Children having the scan without sedation or general anaesthetic do not need to fast or stop eating and drinking before the scan, unless stated in the appointment letter.
Your child should wear clothes without zips or metal poppers for the scan – otherwise they will need to change into a gown. Before the scan starts, the nurse or radiographer will check you or your child do not have a pacemaker, metal implants or clips, dental braces, a history of metal fragments in the eyes or any allergies. We will ask you to sign a form to confirm this. If you are wearing a medication patch, for instance, for pain relief or to quit smoking, please remove this before you go into the scanner room. You will also need to leave metallic objects like jewellery, watches, keys, pens or cards with metallic strips like bank cards and train tickets in the lockers outside the scanner room.
You are welcome to stay with your child during the scan, but if you are in the first three months of pregnancy, you should let us know beforehand. If your daughter is 12 years old or older, we will ask her about her periods and any possibility she could be pregnant.
Your child will be able to watch a DVD during the scan, so please bring along any favourites. It can also help if your child has a favourite toy to hold as well.
What does the scan involve?
Your child will need to lie on the bed for the scan. Depending on the part of their body being scanned, they may need to have a coil over part of their body or wear a head coil (this will not touch their head).
When your child is in the correct position, the radiographer will move the bed inside the scanner and then go into the control room. The scanner will make a continuous knocking sound throughout the scan, which can be quite loud, but we will give you and your child ear protectors to minimise any discomfort. If your child is watching a DVD, or listening to a CD, this will distract from the noise too.
The radiographer will warn you and your child when a loud noise is due by talking to them through an intercom. When the scan has finished, the radiographer will move the bed out of the scanner and your child can get up and leave.Are there any risks?
There are no risks associated with MRI scans. They are painless with no lasting effects. The scanner does not touch your child during the scan. MRI scans are not suitable for people with certain metal implants inside them (such as pacemakers) because the scanner emits a strong magnetic field. This is why we carry out a thorough metal check before your child has the scan.
What happens afterwards?
In most cases, your child will be able to go home straight after the scan has finished. The radiologist (doctor specialising in scans) will send a report of the scan to your child’s doctor in time for their next appointment. If you have not been given a follow up appointment to see your consultant, please contact their secretary after two weeks.

Why It’s Done
MRI is used to detect a variety of conditions, including problems of the brain, spinal cord, skeleton, chest, lungs, abdomen, pelvis, wrists, hands, ankles, and feet. In some cases, it can provide clear images of body parts that can’t be seen as well with an X-ray, CAT scan, or ultrasound. MRI is particularly valuable for diagnosing problems with the eyes, ears, heart, and circulatory system.
An MRI’s ability to highlight contrasts in soft tissue makes it useful in deciphering problems with joints, cartilage, ligaments, and tendons. MRI can also be used to identify infections and inflammatory conditions or to rule out problems such as tumors.
An MRI exam usually takes 20-90 minutes to perform, depending on the type of study being performed. Your child will lie on the movable scanning table while the technologist places him or her into position. The table will slide into the tunnel and the technician will take images. Each scan will last a few minutes.
To detect specific problems, your child may be given a contrast solution through an IV. The solution, which is painless as it goes into the vein, highlights certain areas of the body, such as blood vessels, so doctors can see them in more detail. The technician will ask if your child is allergic to any medications or food before the contrast solution is given. The contrast solution used in MRI tests is generally safe. However, allergic reactions can occur. Talk to your doctor about the benefits and risks of receiving contrast solution in your child’s case.
As the exam proceeds, your child will hear repetitive sounds from the machine, which are normal. Your child may be given headphones to listen to music or earplugs to block the noise and will have access to a call button in case he or she becomes uneasy during the test. If sedated, your child will be monitored at all times by a machine that checks the heartbeat, breathing, and oxygen level.
When the exam is over, the technician will help your child off the table; if sedation was used, your child may be moved to a recovery area.
