Few Useful Websites on
Doppler Ultrasonography

ATL Protocol Guides at http://www4.medical.philips.com/Education/ProtocolGuides/ProtocolGuides.asp is a collection of downloadable guides in PDF format that provide basic protocol information on a range of sonographic and Doppler exams. The basic material available comprises of cardiology, musculoskeletal, menís and womenís health. Expectedly, the vascular section of the protocol downloads are the largest with ten items available. These include ICA Stenosis, Lower Extremity Arterial Stenosis, Renal Artery Stenosis, Venous Imaging, Intraoperative Color Duplex, Transcranial Doppler, and Dialysis Access Graft Imaging . Adobe Acrobat Reader is needed to view these files.

2. Biosound Esaote
at http://www.biosound.com/literature.html offers the material on Doppler in Adobe®. The material includes Duplex and Color Flow Evaluation of the Liver, Duplex and Color Flow Evaluation of Mesenteric Ischemia, Venous Imaging of the Lower and Upper Extremities Arterial, and Carotid Duplex Imaging Protocol.

Applied Radiology at http://www.appliedradiology.com/ has an assortment of downloadable articles on the clinical application of Doppler sonography. A mandatory free registration is now required to view the full text of Applied Radiology articles. Some of the interesting articles related to Doppler include Doppler sonography of the hepatic vasculature - November 2000, Changing principles of cerebrovascular Doppler interpretation - February 2000, Transcranial Doppler: Practical applications in pediatrics - April 1999, A common-sense approach for diagnostic imaging of carotid vascular disease - July 1997, Sonography of the transplanted kidney - May 1997 and Imaging of ovarian malignancies - October 2000.

4. Carotid Duplex Imaging: Protocol and Technique at http://www.biosound.com/CME/CarotidProtocol/carotid_duplex.html is authored by Gail Size, and Dan Meibers. The protocols and techniques are illustratively described. The high resolution images may take several minutes to download, but is worth the effort.

Applications Of Transcranial Doppler Ultrasound at http://www.medana.unibas.ch/eng/tcd/tcd0.htm is a concise and comprehensive web page covering an important and an emerging area in clinical practice. The site builds up the topic commencing with chapters on Doppler ultrasound in medicine, Cerebral hemodynamics, the history of Transcranial Doppler. Also, the physical principles of Doppler and spectral analysis as well as the examination techniques are illustrated. Significantly, material on Window search, Artery identification, Normal values, Doppler parameters and Cerebral arterial blood flow velocity and cerebral blood flow are also depicted.

6. Aachen Guide to Head & Neck Sonography at http://www.klinikum.rwth-aachen.de/webpages/Hno/sonography/USGuideMainPage.html has been created by Dr. Peter Jecker and Prof. Martin Westhofen. This site has material on basic Doppler techniques as a part of Head and neck sonography. Additionally, the site has a variety of material on the application of USG in otolaryngology. Some of the interesting topics include Sonoanatomy of the normal head and neck , Benign head and neck masses, Tumors of the floor of the mouth, the tongue and the pharynx, Head and neck lymph nodes. Also, there is an "Alphabetical index of the Head and Neck cases" available at http://www.klinikum.rwth-aachen.de/webpages/Hno/sonography/USGuideAlphabet.html

Introduction to Echocardiography and Introduction to Doppler at http://www.echoincontext.com/basicDoppler.asp are "monographs produced for beginners to get a quick overview of echo and Doppler". This material, which was originally published by Medi-Cine and distributed by Ciba-Geigy / ICI, has principally four parts : Part I Principals of Doppler Echocardiography and the Doppler Examination ; Part II Doppler Evaluation of Valvular Regurgitation ; Part III Doppler Evaluation of Valvular Stenosis; Part IV Doppler Color Flow Imaging. Some of the material is downloadable too.

An Atlas of Intracardiac Flow Imaging is accessible at http://mbi.dkfz-heidelberg.de/mbi/sfb414/usheart/3d_doppler/page1.html This material though aimed at the Cardiologists has some useful images on the application of Doppler in vascular conditions.

Non-Invasive Arterial Testing is a part of the Basic Radiology Imaging Lectures http://medicine.creighton.edu/radiology/Noninvarttest.html The contents include Resting Segmental Pressures, Basic Principles, Qualitative Wave-Form Analysis, Duplex Ultrasound Imaging with Color Flow and Quantitative Pulsed Doppler velocity measurement

10. Noninvasive Evaluation of Peripheral Arterial Disease at http://ej.rsna.org/ej3/0079-98.fin/doppler.htm is a basic primer on non invasive imaging by a group of authors from San Francisco VA and Los Angeles VA Medical Centers. The site has diagrammatically approached the topic covering
areas such as
at http://ej.rsna.org/ej3/0079-98.fin/hemodynamic.htm and
at http://ej.rsna.org/ej3/0079-98.fin/technique.htm
Interestingly, Video Clips augmenting the material are available at


Power Doppler Ultrasound in neonates is an elegant and concise material available at http://utenti.tripod.it/bartox/power_doppler_neonatology-2.htm The material has been authored by Marco Bartocci from Department of Neonatology, Gaslini Institute, Genoa, Italy.

A basic slide presentation on Ultrasound and Doppler slides by Susan M. Blanchard is accessible at http://www.bae.ncsu.edu/bae/courses/bae465/1999/slides/ultrasound/index.htm Also, Renal Artery Duplex is dealt at http://www.vtmednet.org/vascular/rad.htm
