  • This video covers the differences, clinical applications, interpretation and radiation dose of a DMSA and MAG3 scan. It is ideal for med students and for newly qualified urologists/nuclear medicine physicians who want an in-depth review of renal scans.
    - DMSA is mainly used for the early diagnosis of pyelonephritis in children or for identifying renal scarring after recurrent urinary tract infections. If left untreated, renal scarring may lead to hypertension, proteinuria and end-stage renal disease.
    - The MAG3 renogram is a dynamic study in which the perfusion into the kidneys and drainage out of the kidneys can be followed. It is mainly used to detect hydronephrosis or renal tract obstruction.

    Hi Dr. Paulien! I just found your channel and absolutely love your videos! I am a nuclear medicine technology student and am currently completing my internship year. I'm hoping to use your videos to help study. I was wondering if you could make more videos on radiopharmaceuticals and how they are made?

      Hi Melody! Thanks for reaching out. Please call me Paulien. It means so much to me that my videos were helpful. Regarding your request, I assume that you have already watched this video about radiopharmaceuticals/cyclotron/technetium generator?
      I'd like to make more videos about radiopharmaceuticals, can you tell me in a bit more detail what you'd like to see covered? :)

      @@dr.paulinemoyaert ​ Yes, of course! Some nuclear medicine departments have a radiopharmacy on-site where they prepare their doses for patient use or they order doses and get them shipped in. For example, I would love to see videos on the process of tagging WBCs with 111 In Oxide or 99m Tc Ceretec. Or in this video you talked about MAG3. What is the process of milking the generator and labeling MAG3 with Tc99m? (I apologize if I used any terms wrong but I hope that helps!)

    I got operated 2 time for left pujo obstruction pyeloplasty 1 was robotic pyeloplasty and then open pyeloplasty.after 8 month of left redo open pyeloplasty mag 3 shows "delayed outflow clearance"
    Pls tell me is it good clearance.

    If one has a stricture, Is the MAG3 an accurate test? i.e. does the MAG3 indicate kidney function regardless of stricture?. If a stricture is removed, would one anticipate the MAG3 results to be better?

      I'm afraid I can't answer this (I'm not yet a nuclear medicine physician - I'm a resident who's currently doing research)

    Mam my child is just 4 months old and he has uti, doctor suggested me to take dmsa scan ,I am very afraid about the scan because he is just 4 months old. Does dmsa scan radiation affect him in future?

    Is it true Dtpa is replaced by mag3?

    • @dr.paulinemoyaert
      @dr.paulinemoyaert  ปีที่แล้ว

      Not completley

    • @sumaranggg
      @sumaranggg ปีที่แล้ว

      No, because they have different renal functions that they picture. DTPA is used to assess glomerular filtration rate (GFR), while MAG3 is for tubular excretion (which means these are alternatively used for patients with severe GFR problem). Both have the same or similar workflow, just what they’re assessing is different.
