We aimed to determine the accuracy and clinical value of CT scans in patients suspected of having acute appendicitis.<h4>Patients and materials</h4>We reviewed outcomes of 125 patients over a 5-month period who had CT scans for the initial diagnosis of acute appendicitis. CT scan interpretations were correlated with surgical and pathologic findings. Follow-up was attempted in all patients who did not undergo appendectomy.<h4>Results</h4>CT scans and clinical courses were complete in 110 patients (88%); 14 patients were lost to follow-up and 1 was excluded. One patient had two CT scans. Thus, there were 111 CT scans available for review. Radiologic interpretation of these CT scans yielded 36 positive (33%), 67 negative (60%), and 8 indeterminate (7%), resulting in a sensitivity of 90%, a specificity of 89%, a PPV of 78%, and a NPV of 96%.<h4>Conclusions</h4>CT scan may be useful in the diagnosis of acute appendicitis, but the reported high accuracy rate was not reproduced at our institution. CT scan was not clinically useful in 21% of patients. We conclude that a CT scan may be beneficial in the diagnosis of appendicitis with selected patients who have equivocal findings. Thus, at our institution, the accuracy of a CT scan does not justify its routine use in patients with clinical findings of appendicitis.","is_dataset_classified":null,"base_score":3.58351893845611,"endowment":3.58351893845611,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"12121697","pmcid":null,"openalex_id":"https://openalex.org/W2161864603","authors":[],"funders":[],"total_grants":0,"fwci":3.1876,"citation_percentile":0.92626728,"influential_citations":0,"citation_trend":[{"year":2013,"count":2},{"year":2014,"count":1},{"year":2016,"count":2},{"year":2017,"count":1},{"year":2019,"count":1},{"year":2020,"count":2},{"year":2021,"count":1},{"year":2023,"count":2},{"year":2026,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0022480402964073?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0022480402964073?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1006/jsre.2002.6407","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/12121697","host_type":"repository"}],"fields_of_study":["Appendicitis Diagnosis and Management","Intraperitoneal and Appendiceal Malignancies","Diagnosis and treatment of tuberculosis","Adolescent","Adult","Aged","Aged, 80 and over","Algorithms","Appendicitis","Female","Humans","Male","Middle Aged","Predictive Value of Tests","Retrospective Studies","Sensitivity and Specificity","Tomography, X-Ray Computed"],"mesh_terms":["Adolescent","Adult","Aged","Aged, 80 and over","Algorithms","Appendicitis","Female","Humans","Male","Middle Aged","Predictive Value of Tests","Retrospective Studies","Sensitivity and Specificity","Tomography, X-Ray Computed"],"keywords":["Medicine","Acute appendicitis","Appendicitis","Radiology","Computed tomography","Diagnostic accuracy","General surgery"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-16T01:58:40.583977Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
