ACCESS quick notes for participants
Notes & hints to help you with scan reading for the ACCESS study.
Optimize your viewing environment
- Ensure the lights in your room are switched off or are very dim
- Use a SMPTE test image to optimize your computer screen
- Adjust the screen brightness & contrast so that you can see BOTH the 0% / 5% box AND the 95% / 100% box
- If you cannot see BOTH the boxes, you should use a different computer screen
Change image / text size
- Increase image / text size using "ctrl+" on your keyboard
- Decrease image / text size using "ctrl-" on your keyboard
- The horizontal bar separating images from questionnaire can be moved up & down with your mouse so that you can see more or less of the panels
- F11 increases overall screen size by hiding navigation bars; toggling F11 again brings them back
- "Joblist" is where you will find your list of scans to review
- We deliver the scans in batches of about 10 at a time
- When you have finished one batch, the next batch will become available
- Each scan requires answering up to 20 questions (the number varies depending on your answers)
- When you have answered the last question (which will always be "question 20"), review your answer selection & scroll to the bottom of the screen to click "finish"
- When you have completed scan questionnaires, you can review feedback
- Feedback allows you to compare your answers to:
- follow-up imaging where it's available
- a "Gold Standard" - a single, expert Neuroradiologist who went through the questionnaire blinded to outcome & follow-up
- the "Gold Standard" may have given answers which are not consistent with the follow-up imaging
- this is because the "Gold Standard" readings represent real life scan reading rather than a biased retrospective assessment
- an "expert panel" - five experts in stroke CT review
- the "expert panel" does not always agree!
- again, this is because the "expert panel" readings represent real life scan reading, in which there can be disagreement
- specialty responses
- the fractions of specialists (e.g. Neuroradiologists vs General Radiologists vs Stroke Physicians) answering a question one way or another
- this information should allow you to compare your responses with those of similar training, & with those who have different backgrounds
- Register to participate & train with ACCESS here.
- Take the BASP CT Training Lecture beforehand here.
- Integrate imaging training with STARS Thrombolysis Masterclass
