The Iron Maiden

Today I had an MRI
I had to lie on a bed
And they pushed me into a tube
Open the pod bay doors please HAL
Came into my head
I lay very, very still
Looking into a mirror
I could see my knees and feet
And the roundness of the machine
It buzzed
It whirred
It groaned
Heavy metal played loud
Welcome to the machine
Helter Skelter

Welcome to the Machine

Pink Floyd

Welcome my son, welcome to the machine.
Where have you been? It’s alright we know where you’ve been.
You’ve been in the pipeline, filling in time,
provided with toys and Scouting for Boys.
You bought a guitar to punish your ma,
And you didn’t like school, and you know you’re nobody’s fool,
So welcome to the machine.
Welcome my son, welcome to the machine.
What did you dream? It’s alright we told you what to dream.
You dreamed of a big star, he played a mean guitar,
He always ate in the Steak Bar. He loved to drive in his Jaguar.
So welcome to the machine.

Helter Skelter

The Beatles

When I get to the bottom I go back to the top of the slide
Where I stop and I turn and I go for a ride
Till I get to the bottom and I see you again
Do, don’t you want me to love you
I’m coming down fast but I’m miles above you
Tell me, tell me, tell me, come on tell me the answer
Well, you may be a lover but you ain’t no dancer
Helter skelter, helter skelter
Helter skelter
Will you, won’t you want me to make you
I’m coming down fast but don’t let me break you
Tell me, tell me, tell me the answer
You may be a lover but you ain’t no dancer
Look out
Helter skelter, helter skelter
Helter skelter
Look out, ’cause here she comes
When I get to the bottom I go back to the top of the slide
And I stop and I turn and I go for a ride
And I get to the bottom and I see you again, yeah, yeah
Well do you, don’t you want me to make you
I’m coming down fast but don’t let me break you
Tell me, tell me, tell me your answer
You may be a lover but you ain’t no dancer
Look out
Helter skelter, helter skelter
Helter skelter
Look out, helter skelter
She’s coming down fast
Yes, she is
Yes, she is
Coming down fast

MRI

Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body.

The MRI scanner is operated by a radiographer, who is trained in carrying out imaging investigations. They control the scanner using a computer, which is in a different room, to keep it away from the magnetic field generated by the scanner.

At certain times during the scan, the scanner will make loud tapping noises. This is the electric current in the scanner coils being turned on and off.

You’ll be given earplugs or headphones to wear.

It’s very important to keep as still as possible during your MRI scan.

The scan lasts 15 to 90 minutes, depending on the size of the area being scanned and how many images are taken.

Most of the human body is made up of water molecules, which consist of hydrogen and oxygen atoms.

At the centre of each hydrogen atom is an even smaller particle called a proton. Protons are like tiny magnets and are very sensitive to magnetic fields.

When you lie under the powerful scanner magnets, the protons in your body line up in the same direction, in the same way that a magnet can pull the needle of a compass.

Short bursts of radio waves are then sent to certain areas of the body, knocking the protons out of alignment. When the radio waves are turned off, the protons realign. This sends out radio signals, which are picked up by receivers.

These signals provide information about the exact location of the protons in the body.

They also help to distinguish between the various types of tissue in the body, because the protons in different types of tissue realign at different speeds and produce distinct signals. In the same way that millions of pixels on a computer screen can create complex pictures, the signals from the millions of protons in the body are combined to create a detailed image of the inside of the body.

Deaths in the UK have risen to 33,186 after 494 fatalities were recorded in the last 24 hours.
