MR Correlated Spectroscopic Imaging for Diagnosing Breast Cancer

PRIMARY OBJECTIVES: I. Non-uniform undersampling schemes (NUS) will be combined with 5-dimensional (5D) echo-planar imaging based correlated spectroscopic imaging (EP-COSI) sequence. II. Group sparsity (GS)-based compressed-sensing (CS) reconstruction schemes will be developed for accelerated acquisition and optimized to reconstruct the NUS EP-COSI data with better reliability. III. Alterations in metabolite and lipid levels will be correlated with apparent diffusion coefficient (ADC) changes in breast cancer patients compared to healthy women which will improve the diagnostic accuracy. OUTLINE: Participants undergo diffusion weighted imaging (DWI)-MRI over 15 minutes and MR spectroscopic imaging over 45 minutes. After completion of study, participants are followed up for 6 months.
