STANDARDIZATION AND QUALITY CONTROL OF AN IN-HOUSE FORMULATION OF ~(99m)Tc(V)-DMSA IN TUMOUR IMAGING AND ASSESSMENT OF TUMOUR BIOLOGY: WORK IN PROGRESS

摘要

biodistribution studies showed predominantly renal pelvicalyceal excretion in a radio-chemically pure preparation with physiological concentration in the bladder. The cardiac blood pool showed significant tracer washout in 3-4 h. A pilot study carried out has so far shown a maximum tumour concentration with adequate target to non-target ratio occurring by 3 h post-injection in patients with histologically proven lung carcinoma.
