What is a TID value?
Transient ischemic dilation (TID) of the left ventricle (LV) is a marker for severe and extensive CAD 13, 14, 15, 16, which has been shown to be of prognostic value 17, 18. However, the prognostic value of TID in patients with an otherwise normal MPS has not been defined.
What is a TID ratio?
TID ratio is defined as: • TID ratio is calculated dividing stress by rest LV volumes; this is. usually done on the non-gated images defining the endocardial limits of the LV but also can be done on the gated, end-diastolic images.
