Forty patients with thoracic or abdominal tumors underwent three computed tomography scans under each guidance method. Breath-hold reproducibility was assessed by measuring the distance between an anatomical landmark and the tumor. Patient preferences for the guidance method were also recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Both guidance methods demonstrated good breath-hold reproducibility. The mean displacement of the landmark-tumor distance was 1.26\u2009\u00b1\u20090.82\u00a0mm with visual guidance and 1.32\u2009\u00b1\u20090.72\u00a0mm with auditory guidance, with no statistically significant difference. No correlation was found between the two methods in individual patients. While 22 patients preferred visual guidance, 12 preferred auditory guidance, and 6 had no preference, the preferred method did not always correspond to improved reproducibility.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Regarding the reproducibility of breath-holding, both auditory and visual guidance methods demonstrated high precision.
