METHOD OF EXAMINING TERMINAL PART OF LARGE INTESTINE

摘要

FIELD: medicine. ^ SUBSTANCE: invention relates to medicine, radiodiagnostics and can be used for detection and estimation of spread of tumours located in rectal ampulla, by method of magnetic resonance tomography. Method includes native and dynamic MR-examination in axial, sagittal and coronary planes, with application of intrarectal contrasting viscous substance (ICVS) and intravenous contrasting preparation of gadolinium, with further comparative analysis of images. As ICVS used is colloidal solution of starch with viscosity 55000-65000 cP in volume 150-200 ml. Dynamic MR-examination is started when contrasting preparation of galidonium is detected in terminal part of abdominal aorta. ^ EFFECT: method ensures reduction of ICVS allegenicity and increase of image visualisation characteristics due to contrasting light background relative to dark intestine wall. ^ 2 dwg, 2 ex
