Use of CT and MR in Trauma Cases

Comparing between CT and MR in diagnosis and treating of head, spine and spinal cord traumatic injuries







 
Abstract

CT and MRI are new modalities that are used to generate axial images of the body. Both CT and MRI add many advantages to diagnose and treat head, spine and spinal cord traumatic injuries. In emergency, CT is the first imaging modality performed because it provides accurate and good quality images in a short period of time. It also has other advantages such as being available in all hospitals and displaying soft tissues, bone and fresh blood all at the same time. However, CT has some disadvantages such as high dose and poor spatial resolution compared to MRI. To get information that may be missed in CT, MRI is used instead because it is excellent in detecting soft tissue abnormalities, but it is a long procedure, poor in evaluating fractures and can cause further damage to the patient. Additionally, many new developments in CT and MR have been invented to overcome the weaknesses of each modality and they help a lot in getting better quality images. Finally, both modalities are used in trauma cases and they complete each other.

excellent review dear SL, as you said, CT has advantage over MRI in truma as a fast and available in most hospitals however apart from radiation risk, MRI more superior (CT not inferior) than CT for anatomy, blood vessels.
my self i prefer CT scan in trauma or stroke but i may ask for MRI or CT perfusion scan for some patients. now we are able to reduce the time frame for a quick MRI stroke protocol and even trauma down to 5-8 minutes,

in my opinion, MRI will substitute CT in for the reasons I said above

thx SL
