Why MRI

MRI is the modality of choice querying soft tissue injuries. The imaging service it provides,
gives conclusive information to determine a client’s next phase of treatment.
The various pulse sequences cause different molecules of tissue in the affected area to be
excited and then relax at different times. The energy released from the excited molecules in
the tissue is captured by gradient coils which acts like the camera. It then transferred the raw
information to the MRI computer as digital MR images.
Slices of the affected anatomy acquired from different pulse sequences are looked at on the
monitor clearly seeing the tissues. The images do not need to undergo any image
reconstruction since MRI images can be viewed in different planes.
A CT scan could have been done to visualize the area through image reconstruction software,
but the exposure to the ionizing radiation would have negated any possible benefits of
achieving the image. The image quality may be of high quality but the area of interest may not
be visualized enough to conclude the extent of the rupture, thus CT would not be used.
Ultrasound maybe be used to identify the rupture, however the image quality may not be of
diagnostic quality, leaving only MRI as the modality of choice for this case.
