Fig. 5From: Dynamic contrast enhanced MRI of pulmonary adenocarcinomas for early risk stratification: higher contrast uptake associated with response and better prognosis72 Year-old male responder, smoker (50 pack years), adeno carcinoma left upper lobe (blue arrow), T3N2M1(Adr, Oss), received PBC, lost in follow-up after 79 days without progression. At day 7 central necrosis in the tumor is seen. Initially, the tumor shows moderate contrast uptake. This is reduced early after therapy and necrosis is visible at 70 s post contrast injection and later. Note the huge costal metastasis, which changed minimally during the course of therapy (red arrow)Back to article page
