title: Fiducial marker guided stereotactic liver radiotherapy: Is a time delay between marker implantation and planning CT needed?
abstract: To minimize the risk of marker migration in fiducial marker guided liver SBRT it is common to add a delay of a week between marker implantation and planning CT. This study found that such a delay is unnecessary and could be avoided to minimize the treatment preparation time.
