By leveraging information across multiple cardiac cycles, our model can rapidly identify subtle changes in ejection fraction, is more reproducible than human evaluation, and lays the foundation for precise diagnosis of cardiovascular disease in real-time. Prospective evaluation with repeated human measurements confirms that the model has comparable or less variance than human experts. In an external dataset from another healthcare system, EchoNet-Dynamic predicts ejection fraction with mean absolute error of 6.0% and classifies heart failure with reduced ejection fraction with an AUC of 0.96. Trained on echocardiogram videos, our model accurately segments the left ventricle with a Dice Similarity Coefficient of 0.92, predicts ejection fraction with mean absolute error of 4.1%, and reliably classifies heart failure with reduced ejection fraction (AUC of 0.97). To overcome this challenge, we present the first video-based deep learning algorithm, EchoNet-Dynamic, that surpasses human expert performance in the critical tasks of segmenting the left ventricle, estimating ejection fraction, and assessing cardiomyopathy. However human assessment of cardiac function focuses on a limited sampling of cardiac cycles and has significant inter-observer variability despite years of training 4, 5. Good luck! I hope this video helps.Accurate assessment of cardiac function is crucial for diagnosing cardiovascular disease 1, screening for cardiotoxicity 2, and deciding clinical management in patients with critical illness 3. Your biggest decision will be to decide your dataflow, if you’d like to assign it to a particular button. To perform these, simply follow the same steps. You may have DICOM Worklist, Print, or other services necessary. For whatever reason, loops sent via network to the DICOM server appear fine on the server. The only way around this issue is to export via network. In certain versions of the GE Logiq e and Vivid e, you’ll find that if you export loops to USB in DICOM format, they won’t show up on the server. Some of these Logiq e and Vivid e machines have issues with certain types of DICOM files, particularly cine loops. However, the screens you’ll see in this video should be similar enough that you can look around and find a similar screen on your machine. Please note that your Vivid e or Logiq e may have slightly different screens, and you may face circumstances that are unique to your situation. To help you, here’s our free step-by-step tutorial in configuring your GE Logiq or Vivid e portable ultrasound machine for connecting and sending DICOM files to a PACS system. The biggest problem here is that You don’t have an alternative: If you want to export, you need to connect to a DICOM Server (or PACS) because exporting to DICOM via USB may corrupt loops, MPEGVue is a mess, and don’t even try exporting in PC format to a USB (you may cry). It wasn’t pretty and I’m ashamed at my language (sort of). In my first attempt many years ago, I spent 20 minutes screaming at a Logiq e. They’ve seen that “Frowny Face” so many times that it’s haunting their dreams. In fact, at least once a week I get a call from a frustrated customer who can’t connect their GE Logiq e or Vivid e to a DICOM server.
