Technologies like computed tomography, magnetic resonance imaging, positron emission tomography, and ultrasound are now integral parts of the medical domain, offering exclusive insights into human anatomy. These techniques not only provide detailed imaging of the human body but also help physicians
> Such nanoparticles do not occur naturally in the human body and must be administered as markers
So if I’m reading this right, much like radioactive markers, these must be surgically implanted before they can capture the imaging? In other words, it’s not a direct replacement for MRI or X-ray imaging technologies, though it could potentially be safer for long term care patients that need frequent imaging.
Not implanted, just injected into a vessel with a needle or catheter. Any time you introduce something like this into the blood though, there are consequences. X-Ray contrast reactions can be lethal and MRI contrast (more similar to these since it’s metal-based) occasionally kills the arteries going to kidneys, which is bad. So, it’s easy to administer, but this is far too soon to claim it is safe at scale.
I had a CT scan after an accident, and no one told me what contrast is going to feel like, the nurse simply injected me without any explanation.
And omfg, that might’ve been one of the scariest 30 seconds of my life. I felt like I was injected with straight up lava. My whole body felt like it caught fire from the inside, and I felt like I would just spontaneously combust any second. It very quickly subsided though and there was no negative reaction overall, just higher sensitivity than average. But holy shit, I would want to know about stuff like this beforehand.
I wish the article touched on the nano particles more… like, what happens to them after you’re done? Are they dissolved or expelled (or do they pile up in various parts of the body and cause chronic issues…)?
