You're invited to join in the recognition of MRI Safety Week from July 27 (the anniversary of the infamous Colombini accident) through to August 2.

#MRIsafety #MRI #Radiology #PatientSafety

Some of you may be thinking, 'hey, isn't MRI the "safe" imaging choice? We're supposed to worry about X-rays and ionizing radiation, and move to MRI when possible, right?'

Well a lot of elements baked into that conventional wisdom have been shifting over time...

Let's start with medical ionizing radiation exposure (predominantly experienced as X-rays). Concern about medical radiation exposure, and resulting technological advancements in imaging equipment, have substantially reduced per-exam patient exposure.

Now eye enjoyed an important question addressed at #EAN2020. Good to think about when you are called to ED for #opticneuritis. Let’s think about it together. Let’s focus on #clinicaldiagnosismaking #meded #medstudenttwitter #medtwitter #neurologyresident @WNGtweets @EANeurology
How do you tell if it’s optic neuritis or not? #painless #unilateral #altitudinal -means top half or bottom half of the field - vision loss more likely to be non-arteritic AION. Any other red flags less likely to be optic neuritis?
Now if it’s #painful it’s more likely #opticneuritis - but what sort? Bilateral vision loss and painful, think #MOG. Unilateral severe vision loss more than pain, think #Aquaporin4. MRI orbits show longitudinal extensive optic nerve enhancement in both. So MRI orbits for clues.

Let’s do a quick one on #clinicaldecisionmaking and #neuroimaging. See bright spot on MRI T2 Brain just means increased water -could be any insult to the brain - #infection #inflammation #ischemia #neoplasm are the top 4 you gotta have in your brain. Pun intended. #MedTwitter
Then you think - active or inactive process? If it’s actively destroying the BBB, it’ll enhance on contrast enhancement. So get MRI with and without contrast. Why without? T2 shine-through - but that’s for another time. #MedStudentTwitter #neurology #neurologyresident
Now the important question here is what you do - remember that nice poem on #theroadnottaken by #robertfrost? 2 widely diverging choices - to immunosuppress or not to immunosuppress. #tobeornottobe #hamlet #MedTwitter #AcademicTwitter #MedStudentChat

I am very excited to share our latest work published in @eLife! We combined #MEG, #fMRI and #MRI for #BrainAge prediction & #biomarker development. Each modality added unique information & enhanced brain-behavior mapping! Thread👇
1/ We combined anatomical MRI (surface area, thickness, volume), fMRI-connectivity and MEG (source power, connectivity, alpha-peak, 1/f, latencies) with a stacking approach (1: ridge, 2: random forest). We made sure our model potentially extracts information from missing values.
2/ Is combining multimodal brain data worth the effort for brain age prediction? Compared to anatomical MRI, fMRI and MEG added similar improvements. Combining all modalities yielded to markedly improved prediction performance. MEG and fMRI contributed independent information!

Why memories of music cannot be lost to #Alzheimer's and dementia
Especially into a piece of music, brain does something called Autonomous Sensory Meridian Response (#ASMR) which feels to you like a tingling in your brain or scalp.
Turns out that #ASMR is pretty special. According to a recently published study in The Journal of Prevention of Alzheimer's Disease (catchy name!), the part of your brain responsible for ASMR doesn't get lost to #Alzheimer's and dementia. #Neuroscience
Sir Paul McCartney believes in the ’healing power’ of music.
"All it is, its little vibrations reaching your heart. Music, you know, it's only little vibrations, little words and little things, but it has this powerful effect."

The bullet journal is out! So excited for day one of #MSSessions19 - met so many old friends already and talked to some first timers Bullet journal page - with MS sessions 19 Bucharest Day 1 a new reality.
Great first talk by @Sabina_Brennan about #BrainHealth Top tip: Keep Smiling more tips on Slide from Sabinas Talk: keep smiling. It’s free. Boosts the growth of brain cells. Learning & memory. Makes your brain more resilient. Lowers blood pressure. Makes you feel happy even if you are not.
Do you feel you have accepted your #MS diagnosis? It’s a changing feeling and can be different day to day - week to week - year to do we adapt and move on with this mix of feelings #MSSessions19 A grasshopper with the headline Accepting/adapting/living

@SimonFanshawe Fairly shocking to find eradication of "mixed wards" By @NHSEngland @NHSImprovmeent was only rebranding exercise & that now they just lie about #male genitalia to #female patients so they have no way to protect themselves. @CMO_England @CNOEngland
@SimonFanshawe @NHSEngland @CMO_England @CNOEngland @Jochurchill4 NHS guidelines:
Grade #1 woman: transwomen with #ladydique
Grade #2 woman: biological female #unraped (of course)
Grade #3 woman: Biological female - rape survivors, it doesnt matter that they can't sleep or scared out of their wits. @Baroness_Nichol
@SimonFanshawe @NHSEngland @CMO_England @CNOEngland @Jochurchill4 @Baroness_Nichol Ideally, of course #Female #Rape survivors (or victims) dont actually show up for medical treatment they need & deserve, freeing up #NHS resources for patients who are not damaged goods & who deserve actual health care.

It is a bit ambitious to try and sum up the magic of MRI physics in one post but here goes! (Thread 1/11) #foamrad #meded #radiology #mri #foamed
Hydrogen atoms are abundant in all of us and are all made up of a single positively charged proton

Each proton has its own magnetic field

When placed inside a magnet (such as within an MRI scanner) the magnetic fields of the protons line up with the main magnetic field (2/11)
Whilst lined up the protons aren’t completely still but rotate 🌀(or ‘precess’) along the axis of the magnetic field

So excited that the paper that is the culmination of my #PhD came out in @ScienceTM today! As the COVER story! Can't wait to share this 6-yr labor of love with the world. Here are some of the main takeaways from the paper:

#BigDay #HealthTech #PortableMRI #HydrationSensor
MRI is a powerful diagnostic tool but it is too expensive ($1.5M) and time-consuming (10-60min) to use on a regular basis. We developed a portable NMR sensor that can harness the diagnostic power of quantitative MRI at a fraction of the time (<1min) and cost ($1k).
It is not necessary to generate images in order to take quantitative magnetic resonance (relaxometry) measurements. Removing the need to generates images makes the hardware simpler, smaller, and cheaper.

I wrote about this for the @MIT_alumni blog:…

About 10 years ago, I was walking home from a slow-pitch baseball game and party with my team. I was a bit drunk, so I walked instead of driving. On the way home I was mugged from behind and woke up in the Rockyview Hospital in #YYC, with a #TBI #concussion. (1 of 13)
I've had multiple concussions from athletics. Football, hockey, rugby & skiing, plus ran over by a car, not once but twice. (think Super Dave Osborne) plus what I have learned since, repeated mildTBIs from the sports. Likely result, I have #CTE. I get worse each year, not better.
Here is what is happening now. I retired from my business some years ago and stopped working completely, 3.5 years ago. I have other progressive diseases besides #CTE, like #COPD #Arthritis #Cancer and more. It is a heavy load and crippling my abilities.

Interesting #Ortho tidbit. SHOULDER PAIN
You're over 40, you go to the doc because your #shoulder hurts. You did NOT have an injury. Many will be sent for an MRI.... 1/?
Bear in mind ... You have a very significant chance that a rotator cuff "abnormality" will be found. Those abnormalities will sound scary .... Partial rotator cuff tears, full rotator cuff tears, and labral tears. 2/?
These can be very alarming to many people... the word "tear" implies you're damaged and therefore something must be wrong -- and perhaps you're thinking it must be fixed. 3/?

10-20% of pregnant women experience depression and/or anxiety during the perinatal period. (peri=around, natal=birth). #MaternalMHMatters #PerinatalMentalHealth
Maternal prenatal stress has been associated with a range of negative outcomes in the baby.. such as obstetric outcomes (e.g. preterm birth, low birth weight), emotional outcomes, behavioural outcomes and cognitive outcomes. Review:…
The biological basis for this is still poorly understood. More research is needed in this area to help identify early markers (as well as protective factors) and to help inform early interventions to ensure the best possible outcome for the mother and the baby.
