I wanted to make this quick video about CT scans vs MRI scans. How do these scans differ?  CT is short for computerized tomography, and MRI is short for magnetic resonance imaging.

Here is the biggest difference between the two:

• CT scans use X-ray radiation but are much faster than MRIs.
• MRI scans use radio waves and magnets to create a very detailed image. 

MRI scans are great for taking images of:
• Joints • Brain tissue
• Breast tissue
• Blood vessels
• Discs
• Organs
• Torn ligaments

CT scans are great for taking images of:
• Bone fractures
• Tumors
• Cancer
• Internal bleeding

Problems with getting CT scans: 
• The amount of radiation that a single scan exposes you to is equivalent to 200 chest X-rays.  •

You often need to go back for subsequent scans, which exposes you to even more radiation. 
• Too much radiation can cause damage to your DNA. When talking about CT scans vs MRI scans, you can see that MRIs are the best way to go.

However, there are certain situations where only a CT scan will work. In that case, I recommend doing three things to help offset the effects of the radiation on the body:

• Take niacin
• Fast before and after
• Consume cruciferous vegetables

I wonder how the new YouTube rules taking affect on 10 Dec will affect Dr. Berg channels. We can't lose this channel its life changing.

Sadly I had 3 times CT scan but none of that 3 hospitals, asked my opinion if I prefer to have an MRI or CT scan but in the last hospital they did MRI too & I wish that none of them will do the CT scan for me & one MRI could of been enough & now I’m worried that having 3 times CT scan in a few months after each other is going to harm me but I was not given the choice to say something or choose something.

[frenchiewilliams]

Thank you Dr. Berg I didn't not know the difference between CT and MRI. I have heard of them but never knew much about them. I needed this information!!!

[tango]

My intake from this video is try to be as healthy as possible to avoid getting acute diseases, so that you never have to be exposed to any of those MRI/CT nightmares.

[RedWolf]

Decision made!! This has been on my mind for a while. Thank you Dr. Berg!!

I had a few CT Scans over the past week which revealed I have/had bowed cancer. Surgery so far seems to have removed the tumours from my large intestines & bladder but it had also spread in small amounts to my liver which they say will be dealt with by chemotherapy. I have stage 4 cancer, I’m 45 and in hospital recovering. I had lost weight and strength so needed a blood transfusion before surgery. On the operating table they apparently had a choice to let me go or cut more so they cut and I’m still here fighting. They have suggested my days may be numbered by the liver cancer but as a husband and father I will fight every day to live a good and full life with my family.
I current have a stoma and have been struggling to eat enough proper foods, I’m enjoying milk, yogurt & ice cream at the moment. I have been vomiting litres of nasty bile and now have a drainage bag down my nose to hopefully try and control it. I may be able to go home in a week or so and chemo will commence a few months after when I’m strong enough.
I did have an ultrasound first and had included some niacin & fasting prior to scans and surgery.

I was double CT-d in the hospital when I had a kidney stone. The first time the doctor made a mistake. He ordered a chest CT when I complained about a lower back pain. Two CT in one night! I was vomiting and had diarrhea for many weeks after that plus my face aged 10 years in a month. When I visited my general practice doctor she literally laughed at me when I told her it must had been because of the CT. She said CT does no harm.

Feels like you've been going through my search history. I was just curious about this days ago. Lol thanks doc.

[MellieBellie]

With an MRI, you get music! 😁🎶 I was in the hospital for a week over the summer. I had one CT scan, and about 7 or 8 MRI's. I wasn't worried about it, but I am glad to know I got more of the less harmful one.
👍

[SinisterMinister]

I just had an MRI yesterday and I feel a lot better about it now!

[AnnabellaRedwood]

Dr Berg that was just so awesome and helpful. I had a CT scan earlier this year though I didn't want to have it. I have been fasting a lot and had no idea that fasting was a way to help my body and counter any possible damage.

[rickallmightyjones]

Gives me some peace. I have to have an MRI done tomorrow for a brain tumor.
Thank you!

[ghostpepper]

I have been feeling dizzy, so my doctor ordered an CT, will have it done on Friday, nut now this come up!

[AntonioDal.]

Unfortunately most people get a CT scan because:
- its cheaper which insurance companies like
- its faster which allows a hospital to use it more often during a day
- hospitals want to use it as long as possible because of ''return on investment'' before replacing all CT with MRI.
- the hospital simply doesn't have a MRI
- the hospital has a MRI but the waiting list is too long
You can get about 1 year worth of natural radiation within 15 minutes from a CT scan. Your doctor should have a very good reason to refer you for a CT over a MRI. Question your doctor.
