Thank you so much.. I never learnd sonographic liver segment . İts hard to me . Thank you for beautiful explain🙏🏻🙏🏻

How about patient has ascites and youre having trouble filling in the vessels ? At times its difficult for me to tell if its thrombosed or not. I drop the PRF still no filling then I increase over color gain and fills in but aliasing appears. I then would increase PRF to get rid of aliasing but then lumen becomes not fully filled 🤦🏻‍♀️. My question is how can I convince the radiologist I did my absolute best in optimizing the image? Do you have any tips when you run into these kind of difficult cases? Thank you in advance

Do the portal veins carry oxygenated or deoxygenated blood to the liver?

Can you show SMV??

6:07 can it be considered a doppler artefact?

Is the SMV waveform supposed to be above eor below the baseline? I keep getting contradictory responses.

at which part of the portal vein do we measure its diameter ?

Thank you
