An accurate diagnosis is even more crucial when AAP is associated with left lower quadrant (LLQ) pain, which has a wide variety of differential diagnoses from self\u2010limiting to life\u2010threatening diseases. This study aimed to evaluate the diagnostic efficacies of physical examination (PE), plain abdominal radiography (PAR), and ultrasonography (US) compared to the computed tomography (CT) scan in patients with nontraumatic LLQ AAP coming into the emergency department.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    This prospective cross\u2010sectional study was performed on 220 patients with LLQ\u2010AAP for &gt; 2\u2009h and &lt; 5\u2009days who underwent PAR, US, and CT after PE. An expert surgeon assigned a final diagnosis. Test characteristics, including diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), and negative PV (NPV), were calculated for PE, PAR, and US, using a CT scan as the gold standard.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Among 220 patients (mean age of 48.17; 55.5% female), PE, PAR, and US yielded an overall accuracy of 30.91%, 35.91%, 50.91%, sensitivity of 75.47%, 62.26%, 39.62%, specificity of 16.77%, 27.54%, 54.49%, PPV of 22.35%, 21.43%, 21.65%, and NPV of 68.29%, 69.70%, and 73.98%, respectively.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    As a result of the highest sensitivity for PE and the highest accuracy for the US, we suggest considering PE as the primary investigation for identifying urgent conditions in patients with LLQ AAP and the US for an accurate diagnosis rather than PAR.\n                  <\/jats:p>","DOI":"10.1155\/emmi\/1681801","type":"journal-article","created":{"date-parts":[[2025,6,10]],"date-time":"2025-06-10T01:49:05Z","timestamp":1749520145000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Diagnostic Value of Physical Examination, Ultrasound, and Radiography Compared to Computed Tomography in the Evaluation of Nontraumatic Left Lower Quadrant Acute Abdominal Pain"],"prefix":"10.1155","volume":"2025","author":[{"given":"Fakhroddin","family":"Kiani","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seyed Mostafa","family":"Meshkati Yazd","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6303-9434","authenticated-orcid":false,"given":"Fatemeh","family":"Zarimeidani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7822-8759","authenticated-orcid":false,"given":"Rahem","family":"Rahmati","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nafiseh","family":"Shabani Mofrad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehdi","family":"Vafaei Nia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5454-495X","authenticated-orcid":false,"given":"Reza","family":"Shahriarirad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,6,9]]},"reference":[{"key":"e_1_2_13_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-68379-9"},{"key":"e_1_2_13_2_2","doi-asserted-by":"publisher","DOI":"10.2147\/rmhp.s295142"},{"key":"e_1_2_13_3_2","doi-asserted-by":"publisher","DOI":"10.22114\/ajem.v0i0.152"},{"key":"e_1_2_13_4_2","doi-asserted-by":"publisher","DOI":"10.1159\/000371583"},{"key":"e_1_2_13_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.emc.2021.07.007"},{"key":"e_1_2_13_6_2","doi-asserted-by":"publisher","DOI":"10.1093\/intqhc\/mzy079"},{"key":"e_1_2_13_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.rcl.2015.06.005"},{"key":"e_1_2_13_8_2","doi-asserted-by":"publisher","DOI":"10.21037\/atm.2016.09.10"},{"key":"e_1_2_13_9_2","volume-title":"What Imaging Strategies Are Effective for Rapid and Accurate Diagnosis of Abdominal Pain Etiologies?
