using this method , immunoscintigraphy had an overall sensitivity of 33 % ( 23 % with 131i-3e1.2 and 50 % with 131i-rcc-1 ) for the detection of lymph node metastases and a specificity of 63 % ( 67 % with 131i-3e1.2 and 60 % with 131i-rcc-1 ) with problems of non-specific uptake by presumably normal lymph nodes .
