Reusibility of the result location variables in other domains.
Simplicity: there is only one location for TULOC for the Lesion Location Identification process. Imaging location is treated as the general location for TULOC, and all result locations are under the RESLOC variable.
Clarity of data representation
Cons:
there is only one result associated with the location questions.
We currently have DIR, LAT, PORTOT, Loc Detail, how many more variables might we need if there are more locations info that we need to represent. For example, the graft use-case where we need to indicate that a location is a graft, or transplant.
Vote:
Approach 2: representing lesion locations as result values
