Routine use of computed tomography (CT) in preoperative planning remains controversial due to concerns about radiation exposure and long\u2010term oncogenic risk. The hypothesis was that CT imaging before FAI surgery would be associated with increased risk of malignancy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A retrospective comparative cohort study with 1:1 propensity score matching was performed using the TriNetX Research Network. Patients undergoing hip arthroscopy with or without a preoperative CT scan were identified using Current Procedural Terminology and International Classification of Diseases, Tenth Revision codes. The primary outcome was incident malignant neoplasm diagnosis following hip arthroscopy. Secondary outcomes included benign neoplasms, endocrine disorders, blood dyscrasias, infertility, testosterone use and cardiovascular disease. Risk was compared with log\u2010rank, and significance was set at\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      After matching, 9127 patients remained in each cohort.
