The images demonstrate cartilaginous defect lateral tibial plateau with subchondral sclerosis and marrow edema.
Edema/hyperemia is also seen in the superior aspect of the fat pad abutting the inferior margin of the patella.
On the axial proton density fat suppressed image, a ruptured Baker’s cyst is visualized posteromedially.

Clinical impact of Ingenia 3.0T

In order to make our musculoskeletal MRI faster, we have chosen to decrease the length of our MSK exams by decreasing the acquisition times of each series to about 3 minutes, whereas in the past we focused on very high resolution acquisition in about 5 minutes.

 

We usually run 5-6 acquisitions for a full study, so we’re saving 10-15 minutes of time per study, so about 40% overall. The high SNR and excellent homogeneity of Ingenia 3.0T with dStream, Xtend FOV, and MultiTransmit have been essential in achieving this balance. We get still outstanding images that are equivalent to our Achieva images; these take 5 minutes on Achieva 3.0T, and we’re doing it on Ingenia 3.0T in 3 minutes."
