<b>Radiation Injury After Hypofractionated Stereotactic Radiotherapy for Peripheral Small Lung Tumors:</b> Serial Changes on CT

Abstract

The pulmonary opacities observed after hypofractionated stereotactic radiation therapy for peripheral small lung tumors may not precisely correspond to the planned target volume (unlike those with conventional radiation therapy) and may change in shape and location dynamically during the first year. Knowledge of these findings is necessary to avoid misunderstandings concerning tumor regrowth or new tumors.
