METHOD FOR MULTISPIRAL COMPUTED TOMOGRAPHY AND INTRAVENOUS ANGIOGRAPHY OF LOWER EXTREMITY VEINS Russian patent published in 2015 - IPC A61B6/00 A61B6/03 A61K49/04 

FIELD: medicine.

SUBSTANCE: multispiral computed tomography and intravenous angiography in varicose vein disease that is ensured by catheterising a saphena of the examined lower extremity with introducing a non-ionic radiographic pigment therein. That is followed by scanning with forming a three-dimensional image of the veins by means of automatic three-dimensional rendering protocols included into a multispiral computed imaging scanner. The scanning procedure is sequential and two-staged, wherein the first scanning stage is initiated 20 seconds after the radiographic pigment has been introduced with a 30-second breath holding; the second stage of scanning is performed 60 seconds later with the patient breathing freely. The first scanning procedure is directed from the foot to pelvis, while the second one - from the pelvis to foot.

EFFECT: more effective diagnosing of the anatomy of the lower extremity venation by facilitating the interpretation of the obtained results, visualisation, higher quality of the vein image 3D-reconstruction with adequate and uniform filling of the lower extremity venous bed with the radiographic pigment.
