so our ER docs order lumbar and cervical CTs all the time but no MRIs. I still don't understand why if you're going to go ahead and order an imaging study of the spine why not just get one that can effectively r/o an epidural abscess and hematoma. I'm not entirely sure but I always thought a CT can miss these quite frequentlyER doctor here - well I am a pain doctor but am boarded EM.
Our job is rule out life threatening illness - that is pounded into our head from day 1 of residency.
Internal medicine differential for abd pain will be most likely to least likely based on whatever the symptoms are
Emergency medicine differential abd pain will be rule out AAA, appy etc - then if nothing else your diagnosis is "abdominal pain unspecified" FU with your doctor.
Unless we are concerned about cauda equina syndrome, epidural abscess/bleed or a few other things we don't order MRIs that can be done outpatient. Also MRI is limited availability as an aside and a lot of places don't have them or don't have 24.7 accesss.
There is much truth in that statementSo much of what we end up telling patients is bureaucratic. What’s right and what is reality are often so diagonally opposite.
If I’m trying to survive however, I’m probably gonna say the evil hospital and ER doc don’t care about your pain and don’t view it as “a true emergency” or “life threatening condition.” Just as they would say, “you need to immediately follow up with your pain doctor and they can take care of this right away.”
We all just pass it along and sell the blame.
It may delay care by not having the MRI but think of all the increased profit the insurance companies will have. It really should be on the spine specialist to get the MRI. Usually, I will order the MRI before sending out to ortho but if I don’t they should still appreciate the referralI often have to fight for an MRI even when I'm trying to rule out Cauda. "Did you speak to Spine yet?" When Spine invariably says why the hell are you calling me without an MRI. MRIs take longer to do, be read, less techs around and most importantly (possibly selfish) would not change my immediate management of the patient. If they have a high WBC, CRP, homeless and back pain - for sure I need to rule out a discitis. If its a radic, MRI proven or not, as long as no red flags, I'm still sending them home with some pain killers and having them follow up with their GP. We see 250 patients per day in our ER, you could argue many may end up getting MRIs in the outpatient setting, but doing them in the ER would bring the department to a standstill.
So what exactly is the real reason ER docs don’t order MRIs of the spine if someone comes in with clear symptoms suggestive of an acute radiculopathy?
I’ve never been able to give patients a good answer.
Ducttape? Or anyone else who might have insight?
2. MRI is not. MRI takes much longer to do, and even when MRI techs are available, the machine is not. i have had multiple patients have their "routine" MRI scheduled for 10 pm on Friday night because of lack of time slots.
single region spine MRI without contrast is about 15 minutes.right. and each scan takes on average 45 minutes.
+10 minutes turnover time.
so 24 MRIs per day is probably max'ing out.
CT scan - 10 min to do the scan, same 10 min turnover. can do 3 CTs at the same time it takes to do 1 MRI.
It is not.single region spine MRI without contrast is about 15 minutes.
Can personally verify it is, at least at my local imaging center. It was actually a little less than 15 minutes of scanning time.It is not.
I can personally verify it isn't...There's more than scan time that must be accounted for.Can personally verify it is, at least at my local imaging center. It was actually a little less than 15 minutes of scanning time.

I think the growing number of uninsured showing up and ridiculous wait timesI’m not criticizing the change but I’m wondering what has driven it.
Absolutely, when I have an emergency and show up at the hosptial I’d prefer for there not to be a line of people with things that could be managed with a PCP sick visit clogging up the system.I think the growing number of uninsured showing up and ridiculous wait times
Radiologist here. As most people said, it comes down to finite resources.
-Finite scanner time: which may be a combination of "studies that can be done per X unit of time" as well as MRI technologist availability.
-Finite radiologist capacity: There's only a handful Dx's that merit getting stat MRI. Those get read. When I was in residency and a BS non-stat MRI for radic got done we let it sit on the list. There's plenty enough stat CT/US/PFs to get read. Beyond that, there's a good portion of radiologists who aren't comfortable doing MRI reads. I'm recently out of training (and happen to be a neurorad) but I wouldn't go read MR outside my subspecialty (MSK/body/etc) in the acute setting if i didn't have to.
This is definitely part of it, how long does it take to get a scan done, and a stat read from radiology, before you can actually decide what to do with the patient. Or is the stat MRI ever really going to change dispo unless there clinical cauda equine or weakness or something.Radiologist here. As most people said, it comes down to finite resources.

I find this perspective very interesting. I trained ( in anesthesiology) in the days when ER medicine was in it’s infancy. I spent ALL NIGHT intubating patients in the ED and ICU. During my internship IM attendings and residents (including me) staffed the ED. At the time the expectation was to go somewhat beyond r/o imminent death. We had plenty of people abusing the ED as a clinic so I don’t think that has changed. My observation as both a physician and as a patient who has been in the ED is that the philosophy has changed to “ your life is not threatened, go home and follow-up with your PCP”. I’m not criticizing the change but I’m wondering what has driven it.

there is a lot of this that is not true. maybe in hospitals that were smaller that utilized PCPs to fill shifts and did not have full time doctors in the ER...Well I will say EM is definitely its own specialty and staffing it with BE/BC EP rather than a potpourri of other docs is better for patient care. I don't think the critical care is the big thing - like you said you were intubating in the ED, ICU can, we can etc. I think we all are good at managing that initial critical illness in the first hour. I think its the undifferentiated patient circling the drain that you just don't know it yet is where our training shines. Rapid DDX prioritizing the life threatening illness and intervening immediately if necessary. I think these patients probably just went home and died prior to EM training. Most patient's that come in don't read the internal medicine textbook. To me it makes a lot of sense but I don't think I quite understood it before I did my training - maybe its just how many damn patients I've seen that I thought - meh probably not this but let me check and sure enough it was that diagnosis cause yeah all of medical school you are not taught to think that when when a patient comes in with a complaint.
The difference is that people only went to the ED for emergencies. Or for things that immediately needed to be treated.I find this perspective very interesting.

One can argue that most renal stones are not true medical emergencies, but having had a half-dozen, pain relief is definitely needed.
One evening the nurses made up a sign “You must be in more pain than the doctor to be seen”

Semi-redundant post, but short of cauda equina syndrome a CT of the lumbar spine is gonna be faster, (significantly) cheaper, and in many cases make the diagnosis anyway.
At least in younger patients without horrible multilevel degenerative disc disease, if you give me a history of "concern for right L4 radiculopathy", I'll spot the disc herniation more often then not. For example: the 35 y/o guy coming in with acute back pain, I'm probably gonna see the disc herniation if i look hard enough. Granted, I fully admit that as a neurorad who reads 50-60% spine all day every day my eye is way more attuned to disc herniations on CT than a mammographer or other general rad would be.
At that point, if I've found the herniation and made the diagnosis, it's really back on you guys. I've done my job. The question becomes: would you do an injection based off CT rather than MRI?
From my perspective, if I can make the Dx on CT then the patient gets discharged faster. If you or whichever provider decides an MRI has to be done (for diagnostic certainty or whatever) it can be done at a low-cost MRI center on an outpatient basis. Considering the ER MRI wouldn't change management, I think it's best for everyone if the patient finds a low-cost MRI center and pays $300 instead of $2000+
Rad here. Generally speaking, CT has better spatial resolution than MRI. Also, to the poster that said MRI spine is 15 minutes, that's not true unless you're doing a limited number of sequences, which has obvious downsides. It's more like 40 min. Problems with scanning spines out of the ER - a.) not emergent (let's remember what the 'E' in 'ER' stands for b.) these guys don't sit still long enough to complete a study and if they do, it's because their pain is now adequately controlled. And if their pain is adequately controlled, then why are we doing the MR in the first place?CT can miss things, MRI is finer slicing; but I agree most MRIs can be done outpt
I dismiss patients for less.I got a page at 2AM last month from my colleagues patient, COT patient, he tells me “I went to the ED because I need a new MRI so I can have surgery, you have to send over the notes so the ED doctor can do an MRI”. He puts the ED doctor on, I ask her any neuro deficits, no, ok have him follow up in the clinic. I had never been more annoyed from a page while on call, I feel for the ED people.
That pt gets ass chewed by me. I have a pt I saw Monday who is about to get an ILESI for radic. I will likely fire her afterwards bc she's passive aggressive to the point it makes my veins itch.I got a page at 2AM last month from my colleagues patient, COT patient, he tells me “I went to the ED because I need a new MRI so I can have surgery, you have to send over the notes so the ED doctor can do an MRI”.

Just be aware that these notes are very easily accessible by patients online now.That pt gets ass chewed by me. I have a pt I saw Monday who is about to get an ILESI for radic. I will likely fire her afterwards bc she's passive aggressive to the point it makes my veins itch.
She's got one last chance to correct that or she's gone.
Edit. Here it is. I did a left ILESI with significant improvement on ADLs and standing tolerance. Left side much better but she refused to agree with me about it. Repeatedly scoffed when I highlighted the improvements she's seen after that shot. She's awful.

If I can copy and paste a response to millennials about why their 30 seconds of back pain and their necessity to need an emergency MRI as soon as possible can be answered in a diplomatic fashion, can someone please share??
I can personally verify it isn't...There's more than scan time that must be accounted
This is more dependent on infrastructure/workflow efficiency, as well as machineI can personally verify it isn't...There's more than scan time that must be accounted for.
