I don’t have time this weekend to do the research but want to point everyone to the article where I found the video’s in my previous post. The article is from the Filarial Journal and can be found here:

Animated documentation of the filaria dance sign (FDS) in bancroftian filariasis


The Ultrasound they mention is as follows:

Ultrasound examination was carried out between 2 pm and 7 pm in a darkened room using a SonoSite 180 PLUS hand-carried ultrasound system (SonoSite Inc.; Washington, USA http://www.sonosite.com/) equipped with an L 38 mm 5–10 MHz linear array transducer. For scrotal ultrasound a frequency of 7.5 MHz was used. The men were examined in a supine position in order to reduce interference by movements of the patients themselves. Ultrasound gel was kept at room temperature to reduce interference from the cremasteric muscle.


This page is as close as I found to ultrasound that was used, see this page http://www.sonosite.com/products/180PLUS/ I think that unit is retired as they have newer even more high resolution versions, check this one out http://www.sonosite.com/products/titan/

Pulsed Wave Doppler

The SonoSite® 180PLUS™ system provides a sensitive and accurate quantitative assessment of blood flow, enabling the user to measure velocities and identify flow characteristics in arteries and veins. Doppler signals are exceptionally clean enhancing diagnostic confidence for vascular exams.

Color Power Doppler

For quickly detecting blood flow in vessels or for guiding the placement of a pulsed Doppler sample volume, color power Doppler is a very sensitive mode that is less angle-dependent than velocity-based color flow. Directional color power Doppler is also available on selected transducers.


I will being doing much more research into this … I have asked someone that has written to me privately to comment on this thread, this person knows far more about ultrasound than I do.


Comments on: "More on Ultrasound View Filarial Worms in Humans" (2)

  1. The more I read about this the more sense it makes.
    The lab tech from GPL said that the way to see the parasite (or whatever) in full was to stain.
    Stain and then use live cell microscopy (dark field ) to see it..to do it she thought with (large disections of areas ) ouch……I like this way much better..
    She said she had seen pieces of all kinds of things..but just pieces.
    So Good job..this might be something huh?
    Hope so..we always hope ..
    Lets keep worken together ..we will get it guys!!
    Blessings in Christ all things are possible

    This is amazing, I have seen the worms and a various come from the skin, and on Dark Field but this is a major breakthrough.
    I would love to speak to anyone who has access to this piece of equipment and knows how to operate it.
