MRI of tears in TFCC ligaments on Ingenia 3.0T

Case Study
Goumas, Chris, M.D. Palo Alto Medical Foundation • USA

Patient history

69-year-old female fell with outstretched arms, landing on both wrists. Triquetral fracture was immediately diagnosed, but 6-8 weeks later she has continued pain on the ulnar side of the wrist. She was referred for a MRI exam at Palo Alto Medical Foundation.

MR examination

The examination was done on Ingenia 3.0T with 8-channel dS Wrist coil.


The total scan time of this wrist exam is under 12 minutes. In order to make our musculoskeletal MRI faster, we have decreased the acquisition time of each series to about 3 minutes, whereas in the past we focused on very high resolution acquisition in about 5 minutes.

Diagnosis

The coronal sequences demonstrate tears in the scapholunate and triangular fibrocartilage complex (TFCC) ligaments. The axial fat suppressed proton density images also show intraosseous cysts in the trapezoid.

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 image quality that is equivalent to our Achieva 3.0T images that take 5 minutes, while we’re doing it on Ingenia 3.0T in 3 minutes."
