Abstract: Objective To compare breast magnetic resonance sequences for their ability to generate high-quality images. Methods A total of 75 subjects were analyzed by breast magnetic resonance imaging using T₂WI，DWI，dynamic contrast-enhanced and delayed T₁WI sequences.The image quality produced by each approach was assessed. Results High-quality images were obtained for 93.33% of patients using T₂WI，18.66% using DWI，72.00% using dynamic contrast-enhanced T₁WI and 97.33% using delayed T₁WI. Conclusions In order to improve the quality of breast magnetic resonance images，we recommend reducing motion artifacts，optimizing the imaging sequence to reduce examination time，properly applying fat suppression techniques，ensuring that the b value for the DWI sequence is chosen correctly， and exploiting the full potential of the integrated parallel acquisition technique （iPAT）.
