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.

Rows 1-2:	Show subject ABC-123 has a single aortic aneurysm from a chest MRI scan.
Row 3:	Shows the said aneurysm is 7.5cm in length (diameter), which is measured from the aortic arch to the abdominal aorta.
Rows 4-5:	Show subject ABC-456 is found to have aneurysms in two locations from a whole-body MRI Scan: RENAL ARTERY and THORACIC AORTA.

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.

Row 1:	Shows the cross-sectional diameter of the left ventricle at end ventricular diastole, measured along the minor axis and specifically at the location of the high papillary muscle. The further anatomical details at which the measurement is set and performed is represented by the CVLOCTX CVLOCDTL NSV.
Row 2:	Shows the cross-sectional diameter of the right ventricle at end ventricular diastole, measured along the minor axis and specifically at just below the tricuspid valve. The further anatomical details at which the measurement is set and performed is represented by the CVLOCTX CVLOCDTL NSV.
