Introduction to the Challenge video¶
Background¶
Prenatal ultrasound (US) measurement of amniotic fluid is an important part of monitoring whether a fetus is thriving in-utero, as it provides a non-invasive way of assessing whether there is too much or too little amniotic fluid. These are each associated with increased medical problems and in the worst-case, death; whether due to intrauterine growth restriction, maternal diabetes, or another condition. Sonographic amniotic fluid assessment can be performed in various ways; the method currently recommended is a semi-quantitative estimate determined by measuring a maximum vertical pocket (MVP).
Manually estimating the MVP can be time-consuming and requires training and experience to perform, both in terms of identifying which areas of the US scan are amniotic fluid, and, choosing the appropriate markers on ultrasound frames on which to base the measurement. Automating these steps would be a major step towards enabling clinicians without sonography training to perform this aspect of point-of-care fetal surveillance and widen access to areas where pregnancy scans in a hospital are not possible, in both high income and low-and-middle incoming country settings.
Challenge¶
In this Challenge, we ask participants to consider the problem of automated measurement of the MVP using a predefined ultrasound video clip based on a linear-sweep protocol. Participants are welcome to join both or either of the two sub-challenges.
The first task is to automatically detect amniotic fluid and the maternal bladder.
The second task is to identify the appropriate landmarks for MVP measurement given the selected frame of the video clip.
