Popis: INTRODUCTION For assessment of lower extremity swelling using lymphoscintigraphy, several nuclear medicine departments in the UK have recently switched from Tc-Nanocoll to Tc-Nanoscan. The aim of the study was to compare quantitative and semiquantitative features of lymphoscintigraphy between these two tracers. METHODS Twenty patients received Tc-Nanocoll and 20 received Tc-Nanoscan either side of the switch-over in our department. Tracers were compared with respect to visualisation of the liver, para-aortic lymph nodes and urine (all graded by consensus from 0 to 3; invisible-to-very prominent); and with respect to ilio-inguinal nodal quantification and ratio of liver-to-summed bilateral ilio-inguinal nodal activity at 120 min postinjection (L/N120). Scans were deemed abnormal when there was lymph diversion through skin or deep system, no activity in ilio-inguinal nodes at 60 min or negligible ilio-inguinal activity (
