(Ivanhoe Newswire) -- A newer version of magnetic
resonance imaging, called the 3-Tesla, can help doctors better assess knee
injuries in patients and help them avoid unnecessary surgery, according to
two new studies.
Lead study author of both studies, Tom Magee, M.D., from
Neuroskeletal Imaging in Merritt Island, Fla., and colleagues compared the
3-Tesla MRI to arthroscopy in terms of being able to detect meniscal tears
in the knee.
Results show the 3-Tesla MRI had a 96-percent accuracy
rate in detecting meniscal tears, identifying 108 of the 112 meniscal tears
that were found after arthroscopic surgery. The 3-Tesla MRI was also able to
identify meniscal tears in three cases that arthroscopy could not.
According to Dr. Magee, the 3-Tesla MRI imaging could
help determine which patients with these types of knee injuries might
require surgery and which might first try rehabilitation to see if the knee
injury would heal on its own.
The 3-Tesla MRI differs from the standard MRI by allowing
a variety of different views of the knee that could then be reconstructed to
supply a three-dimensional image. Dr. Magee also believes this imaging
technique can be useful in detecting other types of injuries as well, such
as ACL tears, MCL injuries, and chondral knee injuries.
