“In MR, time is coverage and resolution,” said Mustafa Bashir, M.D., director of MRI at Duke University Medical Center (DUMC) in Durham, N.C. “Most patients can get through an 18 to 20 second breath hold but there is a large minority who can’t.”
The result? Body MR exams can require more departmental time and resources. For obese patients, the exams can take longer, and for patients who are unable to complete the breath holds, it may mean repeat exams, often with CT. Yet in some clinical cases, an MR exam would actually provide better clinical information.
That’s one reason why radiologists at DUMC are using CAIPIRINHA, a unique parallel imaging acquisition technique that can cut breath holds for 3D T1 exams in half without impacting image resolution, coverage, or contrast.
