MRI stands for magnetic resonance imaging. It is a diagnostic imaging technique that allows your doctor to look inside your body to diagnose disease and evaluate the effectiveness of treatment. There are benefits and drawbacks to an MRI. Magnetic resonance imaging does not expose you to radiation the way a CT scan or x-ray would. On the other hand, while an x-rays or CT can produce an image of your bones, an MRI only visualizes soft tissues in your body.
What Happens During an MRI Scan?
Usually, an MRI requires you to lie on a table that slides into a cylindrical machine that performs the scan. However, some people experience claustrophobia and have difficulty entering an enclosed space for purposes of the exam. If you have claustrophobic issues, a scan from an open MRI machine may be a good alternative.
either case, you will have to remain very still while the MRI is in progress.
Any movement can show up as an artifact on the final image. Depending on the
body part targeted, the process can take anywhere from 10 minutes to an hour or
more. During this time, the natural alignment of hydrogen atoms in your body is
temporarily altered due to a combination of radio waves and a strong magnetic
field that the machine generates around your body. The nuclei of the hydrogen
atoms send out radio signals as they align back into proper position. The
computer converts these signals into 2D images following analysis.

People have a tremendously difficult time understanding why they are not
losing weight even though they are sure they are “only eating X
calories”. They swear up and down that they are counting accurately, and
then the truth comes out. They are guessing at portion sizes, they are not
weighing things, they are using generic brands, etc. Unfortunately, we often
see what we want to believe, so you must assume that every estimation you make
will be too low, even if you try to overestimate. The only fix for this is to
be as precise as possible.
This level of precision is not necessary for everyone. If you are losing
fat as expected by guessing or being less precise, then good for you. This
advice is meant for those that think they are tracking accurately, but somehow
still are not losing fat as measured over at least a 3 week period. If that’s
the case, you need to crack down.
First, sign up for MyFitnessPal (MFP). It has the largest food database of
them all. Others may work, but I will base these instructions off MFP since
that’s what I know.
Everything needs to be weighed, so buy a kitchen scale. Find one that is
digital and can do both metric and imperial (grams and ounces). Weigh in grams
if possible though, it’s more accurate.
Free-pouring liquids (milk, juice) and tiny ingredients like spices, baking
soda, etc, can be measured by volume, not weight. This means cups, tablespoons,
