Gene Regulation and Targeted Therapy in Gastric Cancer Peritoneal Metastasis: Radiological Findings from Dual Energy CT and PET/CT
Published on: January 22, 2018
Abstract:
Eleven patients with malignant peritoneal mesothelioma were examined with ultrasonography. Four of them were also examined with computed tomography (CT). A sheetlike mass was seen in seven patients and a localized irregular mass was seen in four. No nodular or globular masses were seen. Ascites was present in all patients except one, and an omental mass in addition to a peritoneal mass was found in two. Extremely rapid progression of mesothelioma occurred in one patient, and disappearance of mesothelioma and ascites occurred in another. Ultrasonography was, in general, superior to CT in demonstrating peritoneal masses, especially in the presence of ascites.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
