Dr. Robert: The most important figures

to f/u in ADPKD management are function and    Volume of the kidneys.

      To see that, We’re going to get a blood test and   MRI scan

​

Ms. Marian (46 / F): Okay. Doc.

Seven days later...

Dr. Robert: Your kidneys are not bad. eGFR is 78 (mL / min / 1.73 m2). Unfortunately, your images are still waiting for the radiologist's interpretation. In my opinion, there has been no significant change so far…. so go home…and please drink a lot of water...

Ms. Marian: Oh yeah, sir. But, during the time I took an MRI, I was so horrified... I couldn't stand it for an hour and a half again…

Dr. Robert: Yes… I understand… I'm sorry about it… Anyway… Did you have trouble to stop breathing while taking MRI? The quality of the image is not very good.

Ms. Marian: Oh really? The radiologist told me to hold my breath. But, It was too hard to  hold any    longer... Rather, I wanted to stop and scream in the middle.

​

Dr. Robert: I see. Let's see…  how your TKV is…   (applying ellipsoid volume equation)

Ms. Marian: (Watching his monitor) Doc.. Actually I am a math teacher.   Can I ask something....?  I don't mean to offend you, but..   Do you really think    that calculation accurately reflect My TKV? I think it's a little different…

Dr. Robert: Wow… I see….. In the future, Our technology may help to calculate better… :)

She is right...

The answer is planimetry.

but..   I'm so exhausted...

Motion Artifact...

Claustrophobia...

Hard to hold    Breathing...
