Shorter breath-holds help patients and benefit diagnostic confidence
Owing to their condition, many patients at Miami Cardiac & Vascular Institute have difficulty performing breath-holds as needed, for instance, in MRI cine scans of the heart and in MRA examinations.
Avila says that Compressed SENSE allows them to reduce breathhold time to 3 to 4 seconds in cardiac cine scans. “At the same time, we can now – based on cardiac frequency – obtain as many as 30 to 40 cardiac phases without sacrificing resolution, while before Ingenia Ambition, we were acquiring only 20 phases.
“This ability to use Compressed SENSE for obtaining higher temporal resolution translates to a much smoother cine. This allows me to better assess heart function,” Dr. Peña says.
“In MRA, the capacity to acquire a sequence in a single breathhold provides images that are motion-free and high in contrast and detail, advantages that aid in diagnosis,” he says. “With Compressed SENSE, we can reduce the time for the single breath-hold to just 2-3 seconds. Before Ingenia Ambition and Compressed SENSE, the breath-hold requirement was about 8 to 9 seconds, which was too long for some patients.”
