So now that you know what an MRI machine looks like, and how it works,
the next question is what can it do. Well here are some interesting
pictures of the inside of your body, complete with the report that
accompanies them. This is what you can expect to receive after a
visit to Enrique's laboratory.
This patient had a sudden loss of her motor functions (she wasnt able
to move her right arms and legs) 2 months before the study. She went
thru a slow recovery with lot physical therapy and drugs. She was
recovering some of her movements but suddenly all the improvement
stop. We performed an MRI that showed the changes expected for a
lesion of that time (2 months old) but also showed and increase in the
size of the ventricular system( where the Cerebrospinal fluid or CSF
flows) that was causing hydrocephalus. Due to this finding, the
patient went thru another surgery and had a shunt valve installed, the
last word we had from one of her relatives is that she is again on
recovery.
The official report included this: T 1 coronal SE (spin echo) sequence that shows an area of infarction in the left parietal lobe. Also enlargement of the ventricular system is observed.
This patient had syncopes every other day...he is a 50 year old male
without any important background...MRA (Magnetic Resonance
Angiography) was performed due to the fact that he has a short neck
and because of that was a bad candidate to check the entire carotid
and vertebral arteries. So, MRA was chosen. it turn out to have a
normal appearance. A Holter (24 hours monitoring of the heart rythm)
disclosed the cause...an unusual arrytmia was the reason of the sudden
loss of blood supply to the brain.
The official report included this: GE (gradient echo) refocused sequence that shows normal blood flow from the carotid and vertebral arteries. MRA (Magnetic Resonance Angiography) DOES NOT USE CONTRAST INJECTION to obtain this images since the flow of blood (with its water component) gives enough signal to display the vessels. Is an extraordinary and non-invasive method to evaluate medium and big vessels of the body.
A 39 year old male came due to lower back pain after moving stuff from
his home to a depot. MRI shows a bulging disk, that means that there
is no herniation of the diskal content. This is very important since
the managment does not require surgery. Only an MRI can tell with such
accuracy the status of the disks, vertebral bodies, ligaments and
nerve roots.
The official report included this: T1 sagital SE (spin echo) sequence of the spine shows a "bulging" disk at L4-L5 level. The vertebral bodies, disk spaces and spine area clearlya observed.
A 30 year old male that after a soccer game came with
swelling of the knee. A meniscal tear was suspected. The MRI confirmed
the lesion and also showed important swelling within the knee. The
appearance of any structure is easily disclosed in MRI. Here you can
actually see the bones, ligaments, soft tissues and the fluid
collections that appears bright and at surrounds the knee.
The official report included this: T2 coronal Se (spin echo) sequence of the knee. The bright (white) rounded images that surround the knee is fluid related to synovitis or inflamation of the bursaes of the knee in a patient with a sport-related injury.
