How to handle multiple similar DICOM series per patient? about prostatex HOT 4 CLOSED

Some of which carry the exact same DICOM series description, while others have almost the same DICOM series descriptions. My question is how do we want to handle this? Currently, for simplicity's sake we dismiss any duplicate DICOM series or just take the series that has the highest series number. However, we are throwing away possibly valuable data. On the other hand, maybe these duplicate DICOM series are too blurry or too distorted to use and it would only negatively impact our performance. Ideally, we you would want to go through the entire set and for each duplicate, hand pick the ones that you want to keep, but I don't think this is feasible, given the amount of DICOM series and perhaps our lack of expert knowledge. As for the test set, if we encounter multiple, similar DICOM series for a lesion in a certain patient, we could for example classify both of them and take the average. The same tradeoff between possible data loss and negatively impacted performance applies here though. Note that if we do want to take into account every DICOM series we find for a lesion in a patient, our .hdf5 representation and lesion extraction requires some refactoring to support this properly. — You are receiving this because you are subscribed to this thread.

This has indeed been discussed before, but at that point in time I was not aware of cases like for example patient 0191. In this case we have the following DICOM series with ADC in its description: ADC_S3_1 ADC_S3_2 ep2d_diff_tra2x2_Noise0_FS_DYNDIST_ADC ep2d_diff_tra2x2_Noise0_NoFS_DYNDIST_ADC Which ADC should we take in this case? Can we still use the series number as an indicator of what is the best ADC to take, even though they have different DICOM descriptions? — You are receiving this because you commented.
