Purpose: To use imaging data from stereotactic MR-guided online adaptive radiotherapy (SMART) of ultracentral lung tumors (ULT) for development of a safe non-adaptive approach towards stereotactic body radiotherapy (SBRT) of ULT.
Patients And Methods: Analysis is based on 19 patients with ULT who received SMART (10 × 5.0-5.

Introduction: Deep inspiration breath hold technique has shown promise in reducing cardiac toxicity and improving patient outcomes. However, there is a lack of consensus regarding the implementation of abdominal breath hold technique and its impact on cardiac dose. This systematic review and meta-analysis aim to provide insights into the comparative effectiveness of abdominal and thoracic breath hold in mitigating cardiac toxicity during radiation therapy for left-sided breast cancer.

Purpose: Continuous advancements in cancer management have resulted in increased long-term survival rates amongst cancer survivors and in turn have exposed the full extent of radiotherapy-associated morbidities. Radiation-induced coronary heart disease (RICHD) is one of the leading causes of morbidity and mortality in cancer survivors, particularly in those having undergone mediastinal radiation. While mediastinal radiation has been shown to substantially reduce both recurrence and mortality rates in multiple thoracic malignancies, the risk for the development of RICHD is of significant concern.

Background Pulmonary function tests are central to diagnosis and monitoring of respiratory diseases but do not provide information on regional lung function heterogeneity. Fluorine 19 (F) MRI of inhaled perfluoropropane permits quantitative and spatially localized assessment of pulmonary ventilation properties without tracer gas hyperpolarization. Purpose To assess regional lung ventilation properties using F MRI of inhaled perfluoropropane in participants with asthma, participants with chronic obstructive pulmonary disease (COPD), and healthy participants, including quantitative evaluation of bronchodilator response in participants with respiratory disease.

Aims: Breath holding can reduce the cardiac dose in radiotherapy for left-sided breast cancer. We evaluated whether any of the existing commonly used breath-hold techniques was superior in maintaining a more reproducible mean heart dose (MHD) during treatment.
Materials And Methods: This was a single-institution, interventional, nonrandomised, three-armed prospective trial, comparing the reproducibility of MHD in breath-hold radiotherapy using voluntary deep inspiration breath hold (vDIBH), active breathing control (ABC), and surface-guided radiotherapy (SGRT).
