BACKGROUND: Whole-body MR (WBMR) imaging allows the acquisition of images of the entire body in a matter of minutes. Its use has primarily been in the evaluation of possible metastases in the setting of a known primary tumour.
OBJECTIVE: To document the value of WBMR imaging in ten children in whom this was added as an additional sequence when the primary diagnosis had not yet been made.
MATERIALS AND METHODS: Ten children, age range 4 months-15 years (mean 7 years 4 months) had WBMR imaging after initial MR showed an abnormality that raised the possibility of systemic disease. Initial scanning was of the brain (n=1), spine (n=2), retroperitoneum (n=4), hips (n=1), femur (n=1) and wrist (n=1).
RESULTS: Abnormalities were detected in eight patients. Two patients had acute lymphoblastic leukaemia, and another had an anaplastic lymphoma, unsuspected prior to the WBMR. Two patients had a previously undiagnosed neuroblastoma with bone marrow metastases. Two patients had Langerhans' cell histiocytosis. Another had multiple bone lesions due to cystic angiomatosis.
CONCLUSIONS: WBMR imaging may be a useful additional sequence in children in whom a systemic and especially a bone marrow abnormality is suspected.
