Abbreviated magnetic resonance imaging (AMRI) protocols have been proposed to overcome these limitations. This study aimed to develop and validate AMRI protocols and evaluate their diagnostic performance against FDP-MRI in breast cancer diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and methods<\/jats:title>\n                    <jats:p>This retrospective study included 220 women (mean age, 51.4 \u00b1 11.3 years) with ultrasonography-detected lesions, who underwent FDP-MRI from September 2021 to September 2024. Three AMRI protocols were derived: non-contrast (NC)-AMRI: T2-weighted imaging + diffusion-weighted imaging (DWI); dynamic contrast-enhanced (DCE)-AMRI A: first post-contrast subtracted (FAST) + maximum-intensity projection (MIP); and DCE-AMRI B: FAST + MIP + DWI. Two radiologists, blinded to pathology, independently interpreted all protocols and classified lesions using the\u00a0Breast Imaging Reporting and Data System (category \u2265 4 considered positive). Diagnostic performance was compared using Cochran\u2019s Q with post-hoc McNemar tests. Receiver operating characteristic curve and areas under the\u00a0curve (AUCs) were analysed by DeLong\u2019s test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Acquisition times differed significantly between the\u00a0protocols (FDP-MRI: 16 min 5 s; NC-AMRI: 4 min 20 s; DCE-AMRI A: 2 min 41 s; DCE-AMRI B: 6 min 35 s; all p\u00a0&lt;\u00a00.001). DCE-AMRI A\u00a0showed the\u00a0highest sensiti\u00advity (85.26%) but the\u00a0lowest specificity (74.49%). DCE-AMRI B achieved balanced performance with a\u00a0sensitivity of\u00a083.60% (95% confidence interval, CI: 75.82-89.69) and specificity of\u00a085.71% (95% CI: 77.19-91.96), which was comparable to FDP-MRI (84.42% and 90.81%, respectively; all p\u00a0&gt;\u00a00.05).
