How do you calculate TR using R-R in MRI?
not sure if that's even English.
What does low t1 signal intensity mean?
I just had an MRI done and one of the comments was that an area of the scan showed a low signal intensity...as in, something is wrong with the tissue.

What were the benefits of Albert Einstein's work?
Albert Einstein tremendously increased our scientific understanding of the universe in which we live. In terms of technological applications, his work created the theoretical basis for the invention of the laser, which is a highly vital item of technology, and he helped us to use atomic and nuclear power (both for peaceful purposes and for bombs); GPS technology would not be possible without correcting for relativistic time dilation effects, MRI scanners require an understanding of relativistic effects, and so forth. Einstein was tremendously important in bringing about the high tech society in which we now live.
Which medical imaging technique depends on the use of xrays moving in an arc around the body producing a cross sectional image?
Magnetic Regonance Imaging (MRI)
How are polynomials used in science?
In solving multi variable equations such as in the analysis of MRI or CAT scan data. Several thousand equations in several thousand variables are utilized, impossible without a computer.
What is the difference between false negative and false positive MRI?
With an MRI or any other assessment, a false negative is when the test says nothing of concern is present when something actually is. In other words, when a test fails to detect something that is actually present. A false positive is when the test says something is there but actually it is not there.
What does it mean if your MRI results show negative?
It means that they could find nothing wrong on the MRI.
Do MRI scanners have any adverse effects?
MRI scanners have practically no adverse effects. MRI or magnetic resonance imaging works by noting difference of various images created by varying response of different body tissues.
What does it mean if your lumbar MRI results show negative?
It means that they could find nothing wrong on the MRI.
What are the Effects on a defibrillbulator during an MRI?
spinal injuries
What are positive effects about xenon?
Xenon can be used as an anesthetic due to its ability to induce a state of unconsciousness with minimal side effects. It is also used in medical imaging technologies like MRI. Additionally, xenon has potential neuroprotective properties and may be used in the treatment of certain neurological conditions.
Does an MRI cause dehydration?
No. A magnetic resonance imaging machine does not cause dehydration. However, the medical reason for having the MRI may indeed be causing dehydration. Dehydration is not listed as a side effect on the web site: http://mri-side-effects.net/ Some of the side effects listed are the same symptoms of dehydration, but are not an indication that the patient has lost water. The contrast dye that is injected for some MRI scans may have its own issues though: http://www.levinsimeskaisergornick.com/gadolinium.html
Do you need an iv for a mri?
No. Some doctors will order MRI with contrast to facilitate better imaging of some body structures. It is not absolutely necessary to have an IV for an MRI but if your doctor believes it is beneficial to have a the MRI with contrast then it best to consent and have the IV.
What are the side effects of MRI?
The potential side effects of magnetic and electric fields on human health remain a source of debate. In particular, the possible effects on an unborn baby are not well known.
Does MRI have side effects on male genitals?
The MRI has been known to cause minor long-term shrinking of the male genitalia. The amount it will shrink it is hardly anything to be worried about, however; as little as 1/10 of an inch for a single MRI. In the worst cases, it's never been more than 1/2 of an inch from a single MRI.
Can I train to become an MRI tech online?
Great question. I had some difficulty locating specific MRI tech programs online. That being said, you can take a radiology program with a major in MRI's. Most of the online programs ask that you have some experience in radiography before specializing in MRI's. However, DeVry does offer MRI tech classes online. You could start there. Good Luck.
What are the side effects of an mri with contrast?
MRI contrast agents do not usually cause side effects. Rarely, they can cause Allergies (mostly skin rash), nausea. When used in large quantities, they sometimes cause renal failure, but usually not on healthy kidneys.
