METHOD FOR TWO-CYCLE CONTRAST ENHANCEMENT ACCOMPANYING MULTISPIRAL COMPUTED TOMOGRAPHY OF ABDOMINAL AND RETROPERITONEAL ORGANS WHILE FOLLOWING UP ONCOLOGY CASES

摘要

FIELD: medicine.SUBSTANCE: invention refers to medicine, oncology and can be used for two-phase scanning in multispiral computed tomography while following up abdominal and retroperitoneal oncologic cases. A non-ionic contrast medium is administered in a general dose. The dose is administered by two successive boluses in ratio 2:1. A time interval of the two administrations is specified so as to provide forming a combined image of arterial and venous contrast enhancement phases within one scanning procedure.EFFECT: method provides reducing a radiation dose considerably - by 50% as compared to the traditional two-phase scanning by only performing one scanning procedure.3 dwg, 2 ex
