  1. Hi, everyone. Today, we're gonna be talking about a more
  2. innovative and newer way of diagnosing hepatic sto
  3. tosis, which is also known as fatty liver disease by using ultrasound.
  4. So, this technique is called ultrasound derived fat fraction.
  5. So what is ultrasound, derived fat fraction?
  6. So this is a newer accepted way to help diagnose fatty liver disease.
  7. So,
  8. we're gonna be using ultrasound waves to measure the stiffness
  9. of the liver and the fat content of the liver.
  10. And this helps us avoid invasive procedures
  11. like liver biopsies because in health care,
  12. as always,
  13. we want to make sure that we are doing the least invasive
  14. procedure possible as long as it is the more feasible option.
  15. So I've attached a video here.
  16. I cannot play it while presenting. But if you would like to watch it, feel free to do.
  17. So,
  18. the ultrasound tech at the Houston Medical Imaging Center is just
  19. going over in more detail about what they will be doing
  20. during the scan as well as giving the patient resources on
  21. how to schedule an appointment to have this procedure done.
  22. So for clinical application,
  23. we will be using a deep abdominal transducer with a curved design.
  24. And that curved design allows for a deeper penetration into the patient.
  25. So that we can see those deeper structures such as the liver,
  26. we will also be using 1 to 3.5 megahertz which is
  27. a lower frequency. Therefore, once again, we have a
  28. deeper field of view
  29. with a piezo
  30. ceramic element.
  31. And then
  32. to measure everything we'll be using a grid that contains 15 spaces.
  33. So this is really good.
  34. This grid is really gonna measure the attenuation coefficient in the back scatter.
  35. The attenuation coefficient is really gonna help us determine um the
  36. liver stiffness and then the back scatter is really gonna help
  37. determine the fat content.
  38. So they actually compared the ultrasound derived fat
  39. fraction scans to MRI findings and they did
  40. find that those they are comparable to each
  41. other which leads us to our clinical study.
  42. So in 2023
  43. they took 100 and 22 patients
  44. they went through,
  45. but all the patients went through both a
  46. ultrasound derived fat fraction scan and an MRI proton
  47. density fat fraction scan.
  48. So the results from that
  49. study found that there was a positive correlation between the two,
  50. meaning
  51. the MRI findings agreed with the ultrasound findings as well.
  52. So this really helped prove that
  53. the ultrasound direct fat fraction is actually a valuable tool for helping
  54. diagnose hepatic
  55. citosis,
  56. which is really important that we were able to compare the two and see that
  57. it is accurate is is a very accurate way to help diagnose and it is a less invasive,
  58. quicker, easier route to take.
  59. Here are my resources.
  60. Those are, I think both of those are actually case studies that you can or
  61. clinical studies that you can look at.
  62. Um I believe the
  63. second one is actually the clinical study that we discussed right here
  64. and that is all. Thank you.
