Breast and Deep Inspiration Breath Hold (DIBH)

Radiation therapy has been shown to be a highly effective treatment for breast cancer. But the proximity of the left breast to the heart leaves the heart vulnerable to radiation exposure. This has been shown, in some cases, to lead to serious long-term cardiac complications¹.

Many centers are beginning to have patients use Deep Inspiration Breath Hold (DIBH) to move the heart away from the breast during therapy. However, achieving this can be challenging². Patients breathe in different ways at different times and may arch their back to simulate a deep breath in. These different movements can appear similar to a patient’s true breath hold, but do not necessarily separate the heart from the breast.

AlignRT® is commonly used during DIBH to ensure radiation is only activated when the patient is in the intended position.

During a recent study at the University of North Carolina, patients were treated using AlignRT for DIBH. Of these, 0% exhibited radiation-induced abnormalities in blood flow to the heart six months after treatment³.

There are 10 published papers covering the use of AlignRT for DIBH, and accessories are available to make DIBH with AlignRT even simpler for the patient and therapist.

Customer Testimonials

What our users say...

In this single institution, [in the] Phase 2 trial we were able to put on 20 patients and demonstrate that Vision RT can prevent cardiac perfusion defects.

Timothy M. Zagar MD, Assistant Professor, UNC*

Vision RT decreases both the time of breast setup for right and left breast lesions, and has really improved our accuracy. Vision RT has also improved the setup for many other disease sites … it is improving our accuracy and throughput.

Nancy Wiggers MD, Radiation Oncologist, Department Chair, Northside Hospital*

Vision RT is a good way to support the breath hold technique to reduce heart exposure to our patients with left-sided breast cancer.
