Approach 3: taking a similar approach as SEND in MI domain modeling where MI test = microscopic examination, the identified abnormality is the result and the location of the said abnormality is mapped to RESLOC.

Row 1:	Shows one or more lesions have been identified in the lower limb region.
Row 2:	Shows lesion 1 is found in the left popliteal artery, below the knee.
Row 3:	Shows lesion 2 is found in the right femoral artery.
Row 4:	Shows one or more lesions have been identified in the lower limb region.
Row 5:	Shows after treatments, lesion 1 is unidentifiable, suggesting the treatments had worked.
Row 6:	Shows lesion 2 is still present at the right femoral artery.
Row 7:	Shows there are no more lesions identified in the lower limb region.
Row 8:	Shows after treatments, lesion 1 is unidentifiable, suggesting the study treatment had worked.
Row 9:	Shows after treatments, lesion 2 is unidentifiable, suggesting the study treatment had worked.

Pros:

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.
We can represent the different types of lesions in TUORRES, i.e. aneurysm, calcified- annulus or -valvular leaflets, stenosis, or an actual cardiovascular lesion (plaque causing stenosis) in TUORRES, thusly avoiding the creation of "lesion-type" specific TUTESTs.
Because we are dealing with a "lesion (TU) domain", the TUTEST= Lesion Indicator, is created as a "general question" that would allow users to create a record on whether or not a lesion is present in a region. As mentioned in bullet point 2, a lesion can be an aneurysm, calcified annulus or valvular leaflets, stenosis and so on - so TUTEST = Lesion Indicator is all encompassing. This question also allows users to create a negative record when the lesion is no longer identifiable after treatments.
We all like this better yay win~

Cons:

We currently have DIR, LAT, PORTOT, Loc Detail, how many more LOC-related 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, we created a NSV for that.

Approach 1: using result location variables

...

Pros:

lesion location, location laterality and location details are represented as separate TUTESTs - allowing different results.
Represent Graft as part of the ORRES, instead of using a NSV.

Cons:

The need to create lesion type-specific tests (e.g. aneurysm, calcified annuls, etc), causing an expansion of TUTESTs. For each lesion type, you may create:
1. xxx location identification
2. xxx location laterality identification
3. xxx location directionality identification
4. xxx location portot identification
5. xxx location detail identification
Reusibility in other domains is limited, seeing as lesion identification should all be mapped to TU.
In this set up, the previous result becomes the location for the next TEST, this requires good understanding of lesion anatomy and the difference between TSTLOC vs RESLOC in order to map the locations properly and correctly for each corresponding test, step wise.
