• Abstract:

  The main objective of this article is to show the importance of Computed Tomography (CT) in performing an abdominal examination for mesenteric artery ischemia, making it necessary to explore some of the anatomy and physiology of the lymphatic system itself in order to understand it. A 73-year-old male patient, weighing 70 kg, admitted to the emergency department with diffuse abnormal pain, with a confirmed diagnosis of mesenteric artery ischemia. I mention the effect of ionizing radiation for the necessary functioning of the tomograph and the risk-benefit it exerts on the patient to ionizing radiation for diagnosis and radiological protection in Standard NN 3.01 of the National Nuclear Energy Commission (CNEN). As far as the physical procedure of the device is concerned, it is necessary to mention how the positioning works, the acquisition time, the contrast injection phases by programming the injection pump. With regard to the software, through image reconstruction, collimation in windows for framing the structures to be studied, where the program has the possibility of performing 3D reconstructions for a better diagnosis, not forgetting the powerful DICOM and RPACS system in cloud allocation, saving and sending the exams to be connected.
