(A) The comparison of anatomical DVH based on CT in a patient with G3 (Grade 3) RILT and a patient with G1(Grade 1) RILT. (B) The comparison of functional DVH based on perfusion SPECT in a patient with G3 RILT and a patient with G1 RILT. (C) The comparison of functional DVH based on ventilation SPECT in a patient with G3 RILT and a patient with G1 RILT. DVH, dose volume histogram; CT, computerized tomography; RILT, radiation-induced lung toxicity; SPECT, single-photon emission computerized tomography.
