RSR teaching library. Captured still frames from a screen recording, presented in recording order. Frame numbers are positions in this extracted sequence, not original DICOM slice numbers. The recording may skip or repeat slices. Window settings, contrast timing and the visible field are fixed by the source recording.
Use this limited teaching sequence with the newsletter walkthrough. It is not the complete diagnostic study and does not replace review of the full examination.
