1. Worklist

    1. Display ratio : setting needs to be done based on monitor size and resolution (at congresses)
    2. “Show reading”
    3. Predefined columns — order and size of columns
      • Purpose:
        • Radiologists to see the results before going into the viewer → they can see how many nodules, which nodules are calcified, solid, part-solid, and GGN
        • Since entering the viewer takes some time, it is useful and efficient to see the result from the worklist
    4. Tag: +, - to filter the products
    5. Note: mistakes by double clicking when moving to viewer
    6. Favorite: short cut to open the viewer that corresponds to the product
    7. Series & Study description
      • Anonymization — has to have same series & study description
    8. Patient ID & study date
      • Anonymization — for follow-up, it has to have same PID to recognize as same patient but with different study date for follow up CT

  2. LCS PLUS

    1. Baseline
      • MPR: Axial, Sagittal, Coronal, 3D
      • Slice thickness and WWL can be changed
      • Nodule info histogram : shows how much of solid / non-solid part of nodule is distributed with histogram
      • Show calcified nodule : on/off → if turned off, it will show the results without calcified nodules
      • Delete nodule
        • Tuberculosis TB — known that it is usually in level of lung / lobe
        • nodule can be deleted by lobe
      • Nodule size/shape change
        • Size change: changed based on HU threshold
        • Shape change: make the nodule rounder
    2. Examination
      • Arrow to max & min the section
      • “Endobronchial lesion” : LungRADS A
      • “Findings suggesting lung cancer”: LungRADS X
      • “Other significant lesions” : LungRADS S modifier
        • LCS PLUS: emphysema, CAC
    3. Side-by-side
      • Axial (raysum) & Axial (MIP)
        • Advantage: there’s no side-by-side comparison function between axial (raysum) and axial (MIP) in PACS → users say this is very useful
        • when seen in MIP, it shows the vessels more clearly, so users can check if there are nodules that are near the vessels
      • Axial & Sagittal/Coronal
        • users can also compare between axial and other MPR
    4. 3D Summary
      • Most likely radiologists are not interested in this page but can suggest to thoracic surgeons to see where the nodules are located and what type of nodule it is before going into surgery
