Types of Aortic Aneurysm
Renal Artery Aneurysm
There are many ways to ask if someone has an aneurysm. If the person has prior history of a particular type of aneurysm, say, aortic aneurysm, and the physician suspects that the patient suffers from another one, then specialized imaging instruments that are location-specific can be used. Examples are TRANSESOPHAGEAL ECHOCARDIOGRAPHY or TRANSTHORACIC ECHOCARDIOGRAPHY, they are used to look for abnormalities in the chest and the abdomen. The original data elements provided to us by DUKE and ACC, from which we created the examples in the CV-imaging TAUG, whether a patient has an aneurysm is asked in a pre-specified fashion. The questions would look like the following:
Does the patient have Aortic aneurysm? Aortic arch aneurysm? Thoracic aortic aneurysm? Suprarenal abdominal aneurysm? etc.
In this instance the specific anatomical location pre-specified in the question is where the test is performed.

Row 3:
...
Indicates the presence of an aneurysm in the thoracic aorta.
...
Row 4:
...
Shows that the aneurysm led to the dissection of the thoracic aorta.
...
Row 5:
...
Shows the confirmed aortic dissection of the thoracic aorta from the previous assessment then undergoes anatomic classification. In this case, the patient's dissection is classified as Standford Class A, indicating that this aortic dissection involves the ascending aorta regardless of the site of origin [ref].
...
Rows 6-7:
...
Indicate the absence of aneurysms in both the suprarenal and infrarenal abdominal aorta.

However, often Often times when patients complain about chest discomforts and pain, it the occurrence of aneurysm(s) are suspected. It is difficult to pinpoint the exact location of an the aneurysm hence . Hence MRI and CT scan are the most frequently used tools to detect aneurysmthe presence and location of aneurysms. In this scenario, the test location is locations are often broadly defined as the subject's chest, abdominal cavity or the whole - body. The specific location(s) where aneurysms are found are actually locational qualifiers for the resultsidentified/found should be mapped to result location, not test.

From the CV-imaging project we also encountered use-cases where we need sub-loc LOC variables to help to further specify the free-text, detailed, more granular locations where a test is performed. Those These values are indeed clinically relevant location information that should NOT be pre-coordinated into the TEST itself, but are also inappropriate for LOC.
So we need a variable that provides additional, more specific and granular information about a proximate location or a range of location(s).
This example shows the minor axis cross-sectional diameter measurements of the left and right ventricle of the heart, at end ventricular diastole.
