However, the value of new kinetic parameters derived from UF\u2010DCE need clinical evaluation.<\/jats:p>\n <\/jats:sec>\n \n Purpose<\/jats:title>\n To evaluate the diagnostic performance of the maximum slope (MS), time to enhancement (TTE), and time interval between arterial and venous visualization (AVI) derived from UF\u2010DCE MRI using compressed sensing (CS).<\/jats:p>\n <\/jats:sec>\n \n Study Type<\/jats:title>\n Retrospective.<\/jats:p>\n <\/jats:sec>\n \n Population<\/jats:title>\n Seventy\u2010five patients with histologically proven breast lesions. The total number of analyzed lesions was 90 (61 malignant and 29 benign).<\/jats:p>\n <\/jats:sec>\n \n Field Strength\/Sequence<\/jats:title>\n \n 3T MRI with UF\u2010DCE MRI based on the 3D gradient\u2010echo volumetric interpolated breath\u2010hold examination (VIBE) sequence using incoherent\n k<\/jats:italic>\n \u2010space sampling combined with a CS reconstruction followed by conventional DCE MRI.\n <\/jats:p>\n <\/jats:sec>\n \n Assessment<\/jats:title>\n The diagnostic performance of the MS, TTE, AVI, and conventional kinetic analysis was analyzed and compared with histology.<\/jats:p>\n <\/jats:sec>\n \n Statistical Tests<\/jats:title>\n Wilcoxon rank sum test, receiver operating characteristic analysis.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The MS was larger and the TTE and AVI were smaller for malignant lesions compared with benign lesions: MS: 29.3%\/s and 18.4%\/s (\n P<\/jats:italic>\n \u2009<\u20090.001), TTE: 7.0 and 12.0 seconds (\n P<\/jats:italic>\n \u2009<\u20090.001), AVI: 2.7 and 4.4 frames (\n P<\/jats:italic>\n = 0.006) for malignant and benign lesions. The discriminating power of the MS (area under the curve [AUC], 0.76) was slightly better than that of conventional kinetic analysis (AUC, 0.69) and comparable to that of the TTE and AVI (AUC, 0.78 and 0.76 for TTE and AVI, respectively). Invasive lobular carcinoma had smaller MS (21.8%\/s) among malignant lesions (29.3%\/s).\n <\/jats:p>\n <\/jats:sec>\n \n Data Conclusion<\/jats:title>\n The MS, TTE, and AVI can be used to evaluate breast lesions with clinical performance equivalent to that of conventional kinetic analysis.
