Abstract In a retrospective study we evaluated the agreement between the results of meta-iodo benzylguanidine (MIBG) scintigraphy and abdominal ultrasonography (US) in the diagnosis and follow up of neuroblastoma (NBL) with respect to the abdominal region. Data of 28 consecutive paediatric patients with NBL or suspected NBL were included (16 M/12 F, mean age 2.9 years, range 3 weeks – 13.4 years). The results (as judged by the nuclear physician or radiologist, respectively) of 60 MIBG examinations (123I and 131I, including 26 single photon emission computed tomography (SPECT)) and US, respectively, performed within a period of 14 days, could be evaluated. Full agreement was reached in 37 comparisons (62%), while partial and no agreement was found in 17 (28%), and 6 (10%) comparisons, respectively. In 8 out of 37 comparisons with full agreement, 12 diagnosed lesions were histopathologically proven, while 11 comparisons with negative findings were also negative in other clinical modalities. US diagnosed correctly in 68% of the histopathological proven lesions, while this was 54% for MIBG scintigraphy. In approximately 50% of the MIBG scans in which SPECT was available, SPECT provided significant additional information. Conclusion Congruent results of MIBG scintigraphy and ultrasonography in the detection of abdominal lesions in patients with suspected neuroblastoma indicate a high reliability in the diagnosis and localisation. Due to the favourable results of additional SPECT, it is advisable to perform SPECT routinely in this diagnosis.
