Systematic review: IGRT and its impact

Purpose/Objective:

Image-guided radiatiotherapy is known by its acronym IGRT and refers to quality control with images in the treatment equipment. This technique allows us to obtain 3D and volumetric images of the patient and the tumor before and during treatment. This helps us to ensure patient positioning and proper tumor localization, from the fusion of the initial CT image with the image of the patient in the accelerator. In this way, we can ensure that what was planned in the initial TC is repeating on day a day in the accelerator. Thus, tumor margins can be reduced and adjacent healthy organs can be protected. IGRT also allows us to irradiate tumors in organs that have movement (4D) and fundamentally that vary with respiration. In other words, with IGRT we achieve greater precision in the delivery of doses to the tumor and the patient's position and repositioning, if necessary, is recorded on a daily basis. The importance of IGRT leads us to ask ourselves what has been studied about it. For this purpose, a systematic review has been developed based on a bibliographic mapping of the literature in WoS applying different inclusion/exclusion criteria, in which 32 documents were selected and subjected to an analysis of their main characteristics.

Material/Methods:

The methodological process employed was a bibliographic mapping of the literature in Web of Science database (WoS) that includes the Pub-Med database; which contains important bibliography in the scientific/health world, by entering keywords in the search equation and applying different inclusion (open access, article format, English languages and year of publication) and exclusion criteria (reviews and titles unrelated to the study), in which 32 documents were selected and subjected to an analysis of their main characteristics.
