Focused Radiation Hepatitis after Bragg-Peak Proton Therapy for Hepatocellular Carcinoma: CT Findings.Okumura, Toshiyuki; Itai, Yuji; Tsuji, Hiroshi; Matsueda, Kiyoshi; Matsuzaki, Yasushi; Tsujii, HirohikoJournal of Computer Assisted Tomography: September/October 1994 Case Report: PDF Only Abstract Radiation hepatitis is clearly demonstrated by noncontrast and contrast enhanced CT following radiotherapy for liver diseases. Radiation hepatitis is dependent on dose distribution and is usually demonstrated as a non-segmental bandlike lesion after photon therapy. We report a case of focused, oval-shaped radiation hepatitis that was induced by photon therapy. The attenuation difference was localized in a high-dose area caused by Bragg-peak proton therapy.
