Basic pulse sequences in the diagnosis of abdominal pathology

Abstract

Magnetic resonance imaging is used for diagnosing abdominal and retroperitoneal space pathology, which allows visualizing focal or diffuse lesions in the parenchymal and hollow viscera with high diagnostic accuracy and reproducibility. Magnetic resonance imaging has advantages over computed tomography in the sensitivity and specificity of determining pathological changes in parenchymal organs, bile ducts and ducts of the pancreas, peritoneum, and retroperitoneal space. The multiparametric protocol provides information about the mutual topography of organs and their structure and the functional state of tissues. This allows to move from structural to functional evaluation. In most cases, the standard abdominal protocol includes T1-weighted images, T2-weighted images, diffusion-weighted images, and magnetic resonance cholangiopancreatography. Depending on the objectives and patients condition, this protocol can be significantly reduced or supplemented. Existing technical developments and achievements make it possible to simplify the scanning process and reduce the time for obtaining images while increasing the reproducibility of techniques in different healthcare institutions.
