Impact of Compressed SENSE in cardiac exams

For cardiologist Dr. Koshi Miyake of Kurashiki Central Hospital (KCH), the most important motive to implement Compressed SENSE in cardiac MRI exams was to reduce the burden of breath holds for the patient, while maintaining high image quality. He hopes this can also help to reduce motion caused by the difficulty for patients to hold their breath.

Compressed SENSE has now been implemented in all cardiac exams at KCH. Thanks to the acceleration, fewer breath holds are now needed, or breath hold times are shortened. The team observes that this reduces the burden of the exam for cardiac patients, without affecting the quality of information required for cardiac function analyses because it’s easier for patients to comply with the breath hold times.


In their previous cardiac cine sequence, KCH was acquiring two slices during one breath hold. With Compressed SENSE, the team increased this to four slices per breath hold.
