OC-0165: Deep inspiration breath hold – can it be detrimental to the heart?

Challenges of maintaining breath-hold conformity for breast patients while using the deep inspiration breath-hold technique

Deep inspiration breath-hold (DIBH) is used for whole breast radiotherapy, as a means of providing better dose homogeneity. This can be achieved by lower doses to the organs at risk, less patient movement and better set up. Most patients offered DIBH treatment are left-sided breast cancer, or ductal carcinoma in situ (DCIS) patients, due to the proximity of the heart to the chest wall so it is ...

short-term administration of l-carnitine can be detrimental to the ischemic heart

Review of deep inspiration breath-hold techniques for the treatment of breast cancer

Radiation treatment to the left breast is associated with increased cardiac morbidity and mortality. The deep inspiration breath-hold technique (DIBH) can decrease radiation dose delivered to the heart and this may facilitate the treatment of the internal mammary chain nodes. The aim of this review is to critically analyse the literature available in relation to breath-hold methods, implementat...

Development of a deep inspiration breath‐hold system for radiotherapy utilizing a laser distance measurer

Deep inspiration breath-hold (DIBH) is a technique for treating left-sided breast cancer (LSBC). In modern radiotherapy, one of the main aims is to exclude the heart from the beam aperture with an individualized beam design for LSBC. A deep inhalation will raise the chest wall while the volume of the lungs increase, this will again push the heart away from the breast to be treated. There are a ...

Single 20-second acquisition of deep-inspiration breath-hold PET/CT: clinical feasibility for lung cancer.

UNLABELLED This study was designed to compare tumor (18)F-FDG uptake between a single 20-s acquisition of deep-inspiration breath-hold PET/CT and free-breathing PET/CT for lung cancer. METHODS Before the clinical study, a phantom study was performed to determine the optimum breath-hold time for the PET scan. We studied 47 patients with lung cancer who underwent free-breathing PET/CT with the ...
