Diagnosis

The study demonstrates tendonosis of the supraspinatus tendon with calcific tendonitis.
Associated degenerative cysts are seen in the humeral head.
Minimal fluid is seen in the subacromial subdeltoid bursa.
Advanced degenerative changes are seen in the acromioclavicular joint.

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."
