So you need a contrast CT or MRI - now what?

Sometimes it's necessary to get a contrast study. You know what? It's ok. Sometimes it's needed to figure out what is going on or rule out something bad. What you can do is have the best material for the study and know how to detox after!

What is crazy is that no one talks about the side effects associated with the contrast media! I am going to go through the different types.

MRI contrast Best choice: CLARISCA (gadoterate meglumine Macrocyclic, ionic Gadolinium is retained for months or years in several organs. The highest concentrations have been identified in the bone, followed by brain, skin, kidney, liver and spleen. The duration of retention also varies by tissue and is longest in bone. Linear GBCAs cause more retention than macrocyclic GBCAs. (Keep in mind also risk of kidney injury with MRI contrast) Gadodiamide (Omniscan) Gadoteridol (Prohance) Gadobenate dimeglumine (MultiHance) Osmolar, non-ionic.

Detoxification protocol: Supplements- Healthology by Dr. Jen

NAC 500 mg twice a day for 1-2 weeks before and 2 weeks after

For 2- 4 weeks post Binder.Pro 1 capsule twice a day (2 hours separate from food and other supplements)

-Infrared sauna

-Epsom salt baths

-Healthy diet and hydration including cilantro, garlic, Energy Bits

EDTA under supervision of a physician (IV, Oral, Rectal)

EDTA Suppositories 750 mg

- 1 a night for five days

- 1 every other day thereafter for a total of 4 weeks #21

CT Contrast

A huge concern is acute kidney injury (AKI)

Steps to mitigate the risk:

Proper Screening

Proper hydration

Limit amount of contrast

Use less toxic contrast material

Mulithance - breaks down faster linear

Low-Osmolar Contrast Media (LOCM)

OMNIPAQUE (iohexol) (Higher rate of AKI)

HEXABRIX (ioxaglate) (Higher rate of AKI)

OPTIRAY (ioversol)

IMERON (iomeprol)

ULTRAVIST (iopromide)

ISOVUE (iopamidol)

Iso-Osmolar Contrast Media (IOCM)

VISIPAQUE (iodixanol) (Lower rate of AKI)

Best choice?

Hands down VISIPAQUE

If you can't get that asked for a less nephrotoxic LOCM

Follow Detox protocol.

Echo Contrast

PEG (Polyethylene Glycol) in synthetic phospholipids echo contrast medium



Optison (only FDA approved ultrasound enhancing agent that doesn't contain PEG)

Uses albumin microspheres (best choice)

Other considerations:

Synthetic lipids kidneys issues

Optiscan concern for crossing BBB, this is concern in the synthetic contrast mediums also.

What do you do?

Ask what type of contrast your local hospital uses.

They usually pick based on cost (You know because saving money is more important then saving kidneys)

Also, it could be because supply chain has a relationship with a certain company.


Op OUT of hospitals that carry crappy testing materials and go to a hospital that cares about outcomes more than a profit.

Talk with doctors in the hospital to make the change. (In my experience it's usually the physicians that operate and make the hospital the most money that they will listen to- think surgeons).

YOU DESERVE BETTER. When it comes down to it- it's all about making money. You have to advocate for yourself to get the best.
