CT & PET Scan Tips
Protect your body from harmful effects of radiation, whilst still getting imaging benefits


CT & PET Scan Protocols

CT & PET scans can be useful in many scenarios, but unfortunately, they have their consequences.  Rather than go into all the details, I’ll keep it short & just say that radiation causes oxidation (ox), & this, along w/ inflammation (Inflam.), is root of pretty much all diseases, esp. cancer (Ca). You can read more in the following articles:


Most of the Pt's at my practice are already on Botanical Treasures, which is mainly turmeric, but also a smattering of other great herbs which selectively protect your good cells from dangerous oxidation & inflam.  Most of my Pt's are also typically consuming @ least a good handful of dark berries / day.  This is a good start, but I suggest that if you’re planning on doing a CT or PET scan, to pick a least 3 of the 7 following supplements & take them 2 days before your scan, day of the scan, & the following 2 days after the scan.  

Doing this, your Dr's can still get a good image, but you don’t get as much damage to your valuable cells & their sensitive DNA w/in them.  In addition to the 3 things below, ask the imaging tech who works the machine to “calibrate” the machine so as to make sure it’s putting out enough radiation to get a decent image w/ your size/weight, & not enough for a 6ft. 5 inch man who weighs 375 lbs.    

   Vit. C—ideally Perque Potent C Guard b/c it's highly reduced form.  3-6g/d in divided doses or half of the amt. that causes you to flush your GI (this is called a Vit. C Flush & has it's own set of instructions).
   Vit. E’s—ideally mixed tocopherols (not alpha) & tocotrienols  600+g/d, w/ food in divided doses.; DFH or Ecological Solutions brands are great.
   NAC—900+mg x 2/d; good w/ food
   Green Tea—Lots.  @ least 7 cups/d, or a concentrate.  (there’s some in Bot. Treasures)
   Red Tea—Lots.  Like at least 7 cups/d, or a concentrate.
   ALA—Alpha Lipoic Acid.  At least 500mg/d.

Another issue for some: potential stress/anxiety assoc w/ claustrophobia of going into the CT scan tube & having to stay still.  If this is an issue, pls talk w/ Oscar re this & we can get you a little herbal tincture mix that is appropriate for your constitution & condition that can help.  You’d take ~30-60 drops of this mix ~15min prior to stepping into the CT room. 


Also, If Doing Scan w/ Contrast, they're typically going to use gadolinium, which might be toxic in hi levels.  Therefore, to prevent from absorbing as much Gad: 

--Definitely take NAC or GSH 2 dys pre & post to help clear out; (PMID: 28934030; PMID: 22815709)

--Be well hydrated for the scan--Herbal tea, coconut water, good clean structured water; "the Solution to Pollution is Dilution!"  ~Walter Crinnion

- Vit D (ideally DAK) 10k IU's/d (PMID: 26041113)
- Zinc ( PMID: 30639754)


For previous exposure - EDTA has a close binding coefficient, the reference for this is pending....


Thanks to Louise Tolzmann, ND for some of this info. 


After an MRI, even if w/out contrast, it's important to do @ least 80min of grounding, ideally for 2 or more dys as MRI's use very hi levels of EMF's & grounding (eg bare feet on outside ground) can offset some of the body's electrical disruption.  You can use wool socks as they conduct electrons as well, you don't have to have completely bare skin; it doesn't have to be 80 contiguous min.  You can just sit outside on a chair & have a foot or 2 touching the ground.  Or you could go for a walk in your socks or bare feet.  Ppl who meditate regularly are most likely to notice disruptions post MRI, but it messes up everyone's EMF's.



Vinpocetine & CoQ10 Combo Alleviates Cognitive Impairment Caused by Ionizing Radiation by Improving Mitophagy; 2022 PMID: 35907514

Objective: Ascertain effx & mechanism of vinpocetine (VIN) & CoQ10 combo on cognitive impairment induced by ionizing radiation (IR). 

Methods: Cognitive impairment in mice induced by 9-Gy IR, & they were intraperitoneally injected w/ VIN, CoQ10, or VIN + CoQ10. Then novel object recognition & Morris water maze tests were used to detect cognitive function. The # of hippocampal neurons & BrdU+Dcx+ cells was observed by Nissl & immunofluorescence staining. Mitochondrial respiratory complex I, adenosine triphosphate (ATP), & mitochondrial membrane potential (MMP) were evaluated, as well as oxidative stress injury. Mitophagy in hippocampal neurons was evaluated by observing the ultrastructure of hippocampal neurons & assessing expression of mitophagy-related proteins. 

Results: IR reduced novel object discrimination index, time for platform crossing, & time spent in platform quadrant, in addition to neuron loss, downreg levels of mitochondrial respiratory complex I, ATP, & MMP, aggravated ox stress injury, increased expression of LC3 II/I, Beclin1, PINK1, & parkin, & decreased P62 expression. VIN or CoQ10 Tx mitigated cognitive dysfunction, neurons loss, mitochondrial damage, & ox stress injury, & enhanced mitophagy in hippocampal neurons. VIN & CoQ10 combo further protected vs IR-induced cognitive dysfunction vs VIN or CoQ10 alone. 

Conclusion: VIN combined w/ CoQ10 improved neuron damage, promoted mitophagy, & ameliorated cognitive impairment in IR mice. 



From ETMS Roundatble Group
I emphasize good hydration &, if there is any concern over potential tox, recommend solid doses of NAC & ALA before, during, & after imaging.  NAC, in particular, has been shown to protect kidneys from harmful effx of gadolinium.  Metformin should also ideally be avoided pre- & post-imaging (for day or 2 on either side).  Other "usual suspects," incl. Immucare II & Cell Guardian would be pretty hi on my list, too...
