For left-sided breast cancer it pulls the heart away from the chest wall and cuts heart dose by about half.","summary":"In breath-hold the lungs inflate, the diaphragm drops and the heart moves down and back, away from the breast and chest wall being treated. The beam is only on while surface tracking or a spirometer confirms the patient is at the right breath-hold level. DIBH is now standard for most left breast and many lymphoma and lung treatments, and is one of the main reasons modern breast radiotherapy carries far less long-term heart risk than it did in the 1990s.","asOf":"2026-09-16","wikipedia":"https://en.wikipedia.org/wiki/Respiratory_gating","links":[{"label":"Wikipedia","url":"https://en.wikipedia.org/wiki/Respiratory_gating"}],"tags":["radiation-wave1"],"related":[],"cancers":["breast-hr-positive","breast-her2-positive","tnbc","hodgkin-lymphoma"],"sections":[],"technologies":["respiratory-motion-management","surface-guided-radiotherapy"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"notes":[],"category":"Procedures"},"route":"/terms/deep-inspiration-breath-hold/","neighbours":{"cancer":[{"id":"breast-her2-positive","kind":"cancer","name":"HER2-positive breast cancer","route":"/cancers/breast-her2-positive/"},{"id":"hodgkin-lymphoma","kind":"cancer","name":"Hodgkin lymphoma","route":"/cancers/hodgkin-lymphoma/"},{"id":"breast-hr-positive","kind":"cancer","name":"HR-positive / HER2-negative breast cancer","route":"/cancers/breast-hr-positive/"},{"id":"tnbc","kind":"cancer","name":"Triple-negative breast cancer (TNBC)","route":"/cancers/tnbc/"}],"technology":[{"id":"respiratory-motion-management","kind":"technology","name":"Respiratory motion management (4D-CT, gating, breath-hold, tracking)","route":"/technologies/respiratory-motion-management/"},{"id":"surface-guided-radiotherapy","kind":"technology","name":"Surface-guided radiotherapy (SGRT)","route":"/technologies/surface-guided-radiotherapy/"}]}}
