## Abstract ## Purpose To investigate short‐ and long‐time‐scale ^3^He diffusion in asthma. ## Materials and Methods A hybrid MRI sequence was developed to obtain coregistered short‐ and long‐time‐scale apparent diffusion coefficient (ADC) maps during a single breath‐hold. The study groups were:

## Abstract Recent investigations have shown that tumors may be distinguished from benign lesions in the breast based on differences in apparent diffusion coefficient (ADC) values. The goal of this study was to assess the magnitude of normal variations in the measured ADC of breast parenchyma durin
