Camelid reporter gene imaging: a generic method for in vivo cell tracking.

abstract：BACKGROUND:Routine work-up for transarterial radioembolization, based on clinical and laboratory parameters, sometimes fails, resulting in severe hepatotoxicity in up to 5% of patients. Quantitative assessment of the pretreatment liver function and its segmental distribution, using hepatobiliary scintigraphy may improv...
