For example, study_id 1395773918 have both left and right neural narrowing on the same slice of the volume. There are some other studies with the same situation. The x and y of the left and right diagnoses are very close to each other. Might those be erronous diagnoses?

These sereis ids to be more specific.

I am not sure but first look at their dicom doesn't seem like both left and right diagnoses can be made on the same slice?

I was thinking into that while considering if do 3 + 2 layer classificator for level + side but I was not sure if left and right were exclusive. So I've decided to leave it into 3 + 3.
\nIt seems like is the case, that they're not fully exclusive, is the only case you've found?
\nEDIT: The same slice, that's more intereasting. May be is a proof of the even for an human hard job to decide wich side are you looking in a specific slice. Is it clsoe to middle?

I am pretty sure these are mislabeled. It is impossible to have left and right foramina on the same slice.
