1H MRS and MRI methods (Lactate, total choline and ADC) were applied to detect therapeutic response in non-Hodgkin's lymphoma patients. Recently developed Hadamard slice-encoded selective multiple quantum coherence chemical shift imaging sequence was used for localized detection of lactate. PRESS and diffusion-weighted EPI were used for tCho and ADC measurements. Lac and tCho decreased after treatment while ADC increased. A 3T scanner was used.
