Are you one of those people who always forgets their doctor’s instructions on medical exams? I get it. Every time the physician starts throwing out acronyms like CT, PET, or MRI, my mind starts drifting off to what I’m going to have for lunch. However, today will be different – this article will break down MRI (Magnetic Resonance Imaging) with and without contrast in terms that even we dimwits understand.
The Basic Idea behind MRI
First thing first: understanding an MRI boils down to knowing its basic idea. An MRI uses powerful magnetic fields and radio waves to generate detailed images of your body’s internal organs and structures so that doctors can diagnose issues more accurately than they could using many other methods.
A Peek into How It Works
When you slide into the bore (a tube-like device) of the machine don’t worry if it feels like being sent back to medieval times: head tilted back under the guillotine blade – they’re not trying to hurt you! They are literally trying to take photos of your insides! Don’t panic; just relax as much as possible—no bouts of hyperventilation on our watch—and let’s roll!
Here is how an average MRI exam would go:
- First things first: Empty any metal objects from pockets or clothing items.
- Relax comfortably onto a narrow padded table.
- Keep still while lying flat on the exam table that slides inside a long tunnel-shaped scanner.
- Lights out—the machine probably shimmies around quite a bit—isn’t bright enough in there for me/can’t see anything anyway?
- After all said done did voila the technologist pulls up some pictures showcasing our ‘inner beauty’—heartfeltly say “thank you” because manners.
So, What is a Contrast Agent?
Sometimes, our bones and organs just don’t give us what we want in terms of images, and that’s where contrast agents come into play.
A contrast agent changes the way magnetic fields interact with your body tissues. For example, some contrast agents are swallowed while you have an MRI scan of your stomach or intestines; others might be injected as part of an IV before imaging your brain to help highlight blood vessels abnormalities. Their presence in the targeted areas sometimes produce clearer image(s) for more accurate diagnosis by physicians.
Differences between MRI with Contrast & Without Contrast
Alright then! Now let’s start comparing these two MRI techniques (with and without contrast).
Basic Definitions Compared
Before we go ahead to discuss similarities/differences between these two-slightly-similar but not-too-different methods (wink), let’s get something straight:
- MRI without contrast: This method involves taking scans using magnetic resonance only – no extras added.
- MRI with contrast: That extra ‘something’—the aforementioned contrast agent—is administered during this method to potentially enhance the quality/accuracy of images obtained from magnets alone.
Possible Benefits when Using Contrast
If contrast adminsitered appropriately based on detailed patient diagnostic investigation records/history details:
- Can draw attention at even minor differences enabling Physician radiologists devise treatment strategies better precisely than they would through manual unaided visual scrutinization.
On the flip side, it can cause challenges such as creating mild-to-late stage allergic reactions ranging from itchiness up to wheezing (and unfortunately likely beyond).
But wait! Didn’t Mama tell you everything has its benefits AND possible side effects? So far so good!
(Don’t say I said it first but next section gingers hot!)
Here Comes All You Need To Know About Risks And Side Effects!
As hilarious as it may seem that an MRI (which is CLINICALLY done!!!) could potentially pack side-effects, it’s a thing—it’s history!
Possible Risks When Contrast Is Used
For most individuals, the impact of using contrast-agent is either insignificant or entirely unavailable. However, as with every medical procedure and methodology that involves foreign agents adminstered into our bodies/immune system:
- In some rare cases for those who may be sensitive to the agent—people with kidney disease have statistically higher probabilities.
- Patients on transplants at risk because their bodies are likely not able to properly expel these agents.
Therefore proper diagnostic usage would notably indicate whether someone faces risks in taking an MRI accompanied by contrast before going through with this method.
Acting On Instructions Like A Pro—What To Do & Not To Do
Having understood what an MRI scan is all about plus appropriate measures needed when considering “contrast” administration during scans which could increase image quality accuracy; Let’s take a quick walk down memory lane on a re-iteration/appropriate reminder of do-and-don’t:
Guidelines to Follow Prior to Appointments
Here’s what you shouldn’t do within 24 hours leading up to your exam ,according to radiologists or below stipulated clinical regulations :
- Refraining from eating/drinking anything apart from water will save extra cleaning later!!
- You also want to avoid smoking/vaping as well within 2 hours prior – let them taste air only!
- Unless they’re medication meant specifically given for imaging procedures: stop popping any pills capable of rendering reduced inhibition levels or cause queasiness until after procedure has been completed.
During Exam Procedures/Final Preparations
What You Should Expect:
Expect noisy machines while lying flat inside! So don’t expect serene-like tranquility please!!
Other general guidance worth adhering during your examination appointment;
Make sure doctor (or other trusted attendant) hands-on certified assists during non-operational procedures; if any
Wear comfortable clothes with no metal attachments—preferably a loose sweat suit sans bra /or little to no metallic jewelleries in order to avoid the rigorous out-of-pocket new clothing replacement expenses.
What You Should Avoid Doing:
Lack of consideration might induce errors during imaging or beyond, such as:
Removing hearing aids/contact lens: large prints please! (Don’t make technician play eye-search!)
Eschewing allergenic items/products!
What you should never ever do is cross your fingers and offer up prayers upon being launched into the bore – just kidding! But seriously though…
Time for Results – What Comes After Exam is Over?
After completing an MRI exam procedure, doctors take time required to accurately READ and compared images taken.
(Whilst results may take some hours at minimum/ten working days maximum depending on where image slides are processed/barred from access?)
Receiving Test Results
When it’s all said done after examination protocol completed before getting either good/bad news…
– Some services places on instant result delivery options but most tend towards schedule appointments post test review(s)
(their system of operation varies).
Wrapping It All Up
MRI scan procedures have been used in medicine for decades now, enhancing patient diagnoses accuracy rates globally. And we hope having read through this article helps keep half our audience awake while connected an ERA in Canada viewed via the included 2-hour MRI video 😊!
