Assessment of fat-suppressing diffusion imaging as a tool for tumor search in primary oncological staging and follow-up after treatment. ⋯ Introduction of diffusion-weighted imaging provides a new independent parameter in oncological scanning. DWIBS meets the requirements of a fast, robust technique. Homogeneous fat suppression allows the use of maximum intensity projections which may visualize the spread of the disease at first glance. Most of the tumor entities examined in this study showed a bright signal in DWI. Exceptions were some osteoplastic metastases and hemorrhaged lesions. Although sensitive, visual evaluation of signal intensity alone showed limited specificity. Detection of lesions in physiological hyperintense structures may be difficult. DWIBS imaging seems to be a sensitive tool in the search for lymphomas and gastrointestinal tumors.
