• 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.

  • ionizing radiation
  • Ultrasonography does not involve the use of ionizing radiation, and the procedure is harmless and can be safely used on anybody of any age. (wikipedia.org)
  • Its availability, the relative advancement in the training of its use, its low cost, and because it does not expose the woman (or fetus) to ionizing radiation, ultrasonography an ideal imaging procedure for women of reproductive age. (wikipedia.org)
  • diagnosis
  • There is a simplified technique called "compression ultrasonography" which can be used for quick DVT diagnosis, mainly for the common femoral vein and the popliteal vein. (wikipedia.org)
  • 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)
  • pregnancy
  • Ultrasonography is a sensitive enough imaging tool that it can accurately differentiate between pregnancy, hemorrhagic ovarian cysts, endometriosis, ovarian torsion, and tubo-ovarian abscess. (wikipedia.org)
  • 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)
  • display
  • In ultrasonography a display in which imaging data are represented as echo amplitudes (on the y-axis) and time (on the x-axis), similar to the way electromagnetic waves are represented on an oscilloscope. (thefreedictionary.com)
  • In ultrasonography, a display that uses dots of differing intensities to represent echoes received from tissues that more strongly or weakly reflect sound waves. (thefreedictionary.com)
  • allows
  • Preinterventional intravascular ultrasonography imaging allows the assessment of plaque distribution, ostial involvement, lumen and vessel area and diameters, extent of calcification, and the presence of thrombi or dissections. (medscape.com)
  • 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)
