Boosting diagnostic confidence with multiple contrasts, multiple orientations in spine MRI
The KCH team has already changed most of their Ingenia 1.5T spine ExamCards by incorporating Compressed SENSE into their 2D TSE, mDIXON TSE, FFE, and 3D sequences.
“Previously with SENSE, our 2D mDIXON TSE scans required relatively long scan times. But now, with Compressed SENSE, we have reduced these scan times while maintaining a high SNR, because the Compressed SENSE technology helps reduce noise,” says Dr. Koyama.
“Because the faster scanning with Compressed SENSE saves us time, we can sometimes add a sequence to obtain high quality spine images in the same time slot for confident diagnoses. And in cervical spine exams, a 2D sequence is sometimes replaced by a 3D protocol, which provides us more information as it can be reformatted in different orientations. Compressed SENSE allows us to easily add this 3D sequence in the timeslot,” says Fukushima
“Incorporating Compressed SENSE in common spine sequences, such as mDIXON, 3D SpineVIEW and eTHRIVE, can substantially reduce the scanning time of these sequences, while maintaining adequate spatial resolution, resulting in high quality, multiple contrasts, multiple orientations,” says Dr. Koyama.
“In addition, fast sequences generally make it easier for patients to stay motionless throughout the scans, so it also helps us in that way.”
