Study population
breast lesions
There were 62 patients (average age, 51.82 ± 11.65 years) who underwent high-temporal-resolution DCE-MRI and 78 patients (average age, 47.29 ± 10.52 years) who underwent low-temporal-resolution DCE-MRI. Among these patients, fifty-six patients with BI-RADS 4 breast lesions (average age, 48.41 ± 11.73 years) were diagnosed and underwent high-temporal-resolution (37.5%, 21/56) or low-temporal-resolution (62.5%, 35/56) DCE-MRI. In BI-RADS 4 patients, the high-temporal-resolution DCE-MRI group included 9 (42.9%, 9/21) benign and 12 (57.1%, 12/21) malignant lesions; the low-temporal-resolution DCE-MRI group included 12 (34.3%, 12/35) benign and 23 (65.7%, 23/35) malignant lesions. The general characteristics of the patients are shown in Table General characteristics of patientsBI-RADS category diagnosed by the senior radiologist*
