Preliminary application of whole body diffusion weighted imaging in screening metastasis.
OBJECTIVE
To investigate the feasibility of whole body diffusion weighted imaging (WB-DWI) in screening metastasis.


METHODS
WB-DWI was performed in 24 patients diagnosed with various types of primary tumors. The three-dimensional maximum intensity projection reconstruction and black-and-white flip technique were used to observe metastatic lesions, and the results were compared with those of bone scintigraphy.


RESULTS
By WB-DWI scanning sequence at b = 800 s/mm2, all the bone lesions found by bone scintigraphy in the cohort were well identified, and other lesions of soft tissue and organs were also well demonstrated. Its screening capability was equivalent with bone scintigraphy in screening metastases in bones (P = 0.062).


CONCLUSIONS
WB-DWI was practicable with the parameter settings attempted in metastases screening.
