Dynamic contrast-enhanced integrated magnetic resonance-positron emission tomography parameters obtained at diagnosis in a patient with right lower lung adenocarcinoma (cT2aN0M0, stage IB). Measured magnetic resonance-positron emission tomography (MR-PET) parameters were as follows: (a, b) SUVmax, 11; (c) tumor size, 3.0 cm (by T1-weighted post contrast); (d) ADC, 1025 (10− 6 mm2/s); (e) Ktrans, 110 (10− 3/min); (f) kep, 598 (10− 3/min); (g) ve, 202 (10− 3); (h) vp, 107 (10− 3); and iAUC60, 253 (10− 3). Measured serum angiogenesis-related biomarkers included VEGF-A (119 pg/mL), angiopoietin-1 (46 ng/mL), angiopoietin-2 (128 pg/mL), and angiogenin (632 ng/mL). Due to medically inoperable status, the patient underwent stereotactic body radiation therapy. The patient achieved a complete response and remained disease-free for 48 months
