The Cedars Sinai
Quantitative Perfusion SPECT package is an interactive standalone
application for the automatic segmentation, quantification, analysis and
display of static (ungated) short axis myocardial perfusion SPECT data.
Features
include:
- Automatic generation
of left ventricle (LV) inner and outer surfaces and valve plane from
LV short axis perfusion SPECT data.
- Two-dimensional
display of stress and rest short axis SPECT images in single or dual
(interleaved or side-by-side) mode.
- Automatic generation
of optimal perfusion normal limits from a normal, a prospective and
a pilot patient population.
- Automatic computation
of functional metrics including LV chamber volume and mid-myocardial
surface area.
- Automatic generation
of stress, rest and reversibility surfaces and polar maps.
- Automatic computation
of global quantitative defect size, both in absolute terms and as a
percentage of the mid-myocardial surface area.
- Automatic generation
of segmental perfusion scores (stress, rest and reversibility) based
on a multi-segment, multiple-point scale, and subsequent derivation
of the global scores SSS (summed stress score), SRS (summed rest score),
SDS (summed difference score).
