• angiography
  • In their appraisal of intravascular ultrasonography and its application in routine angioplasty, Oxford et al have noted that intravascular ultrasonography is better than contrast angiography in key procedural variables, such as measurement of postdeployment stent dimensions, confirming complete stent apposition, and excluding edge dissections that may predispose to both early and late complications, including in-stent restenosis.

  • Nomenclature
  • In 2001, an expert consensus committee was commissioned by the American College of Cardiology, in collaboration with the European Society of Cardiology, to provide a framework for standardization of nomenclature, methods of measurement, and reporting of intravascular ultrasonography results.

  • Clinical
  • [ 11 ] Although no clinical outcome benefits with routine use of intravascular ultrasonography was demonstrated, a more effective stent expansion compared with angiographic guidance alone was noted. (medscape.com)
  • Anticipated clinical and technological improvements in 3-dimensional ultrasonography and MRI may hopefully depict those changes in the cervical connective structures that are responsible for incompetence. (medscape.com)
  • structures
  • For the musculoskeletal ultrasonographer, the selection of anatomic structures to image and the planes in which two-dimensional ultrasonography (US) is performed is primarily complaint-driven. (uptodate.com)
  • vein
  • Ultrasonography in suspected deep vein thrombosis focuses primarily on the femoral vein and the popliteal vein, because thrombi in these veins are associated with the greatest risk of harmful pulmonary embolism. (wikipedia.org)
  • spleen
  • However, because spleen size varies greatly, ultrasonography is not a valid technique for assessing spleen enlargement and should not be used in typical circumstances or to make routine decisions about fitness for playing sports. (wikipedia.org)
  • Procedures
  • Ultrasonography can be used to guide procedures such as treatment for kidney stones with Extracorporeal shock wave lithotripsy, needle biopsies or paracentesis (needle drainage of free fluid inside the abdominal cavity). (wikipedia.org)
  • allows
  • Pleural ultrasonography with evaluation, quantification and aspiration of pleural effusion allows for improved pre-operative staging and alters decision-making patterns for lung cancer patients. (clinicaltrials.gov)
