Radiation injury: imaging findings in the chest, abdomen and pelvis after therapeutic radiation - Cancer Imaging Radiation injury: imaging findings in the chest, abdomen and pelvis after therapeutic radiation - Radiation may be used as adjuvant or primary therapy in a variety of tumors in the chest, abdomen and pelvis. Therapeutic radiation affects not only malignant tumors but also surrounding normal tissues. The risk of injury depends on the size, number and frequency of radiation fractions, volume of irradiated tissue, duration of treatment, and method of radiation delivery. Concomitant chemotherapy can act synergistically to produce injury. Other predisposing factors include infection, prior surgery and chronic illness like hypertension, diabetes mellitus and atherosclerosis.

PET/CT and hepatic radiation injury in esophageal cancer patients - Cancer Imaging PET/CT and hepatic radiation injury in esophageal cancer patients - This paper evaluates the imaging appearance of radiation injury in the liver on positron emission tomography (PET)/ computed tomography (CT) in patients with distal esophageal cancer who underwent pre-operative chemoradiation therapy. Twenty-six patients with distal esophageal cancer who received chemoradiotherapy before esophagectomy were included. All patients had baseline and follow-up PET/CT. Fluorodeoxyglucose (FDG) uptake in both left and right lobes of the liver was evaluated. CT findings suggesting radiation damage were documented.

PET/CT and cross sectional imaging of gynecologic malignancy - Cancer Imaging PET/CT and cross sectional imaging of gynecologic malignancy - Gynecologic cancers are a common cause of morbidity and mortality in women of all ages. While many gynecologic cancers are staged clinically using the International Federation of Gynecology and Obstetrics (FIGO) staging system, imaging can be a useful adjunct to clinical staging. Cross sectional imaging techniques such as ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) have been used to detect and follow patients with gynecologic cancer.
