<qa>  What is the standard uptake value for target lesions?- At least 1 target lesion, as defined by RECIST, that has not been irradiated. New lesions that have developed in a previously irradiated field may be used as sites of measurable disease assuming all other criteria are met. All target lesions must have a unidimensional diameter of at least 1 cm for spiral CT scans if the reconstruction algorithm is 0.5 cm, or an standard uptake value SUV value 2.5. Baseline measurementsevaluations must be completed within 4 weeks prior to treatment.
