Overview

Cedars Cardiac Suite offers a comprehensive array of tools designed to help you with your cardiac patient exams.

  • Cedars QGS (Quantitative Gated SPECT) is an interactive, standalone application for the automatic segmentation, quantification, analysis and display of static and gated short axis myocardial perfusion SPECT.
  • Cedars QPS (Quantitative Perfusion SPECT) is an interactive standalone application for the automatic segmentation, quantification, analysis and display of static ungated short axis myocardial perfusion SPECT.
  • Cedars Blood Pool Gated SPECT (BPGS) v2.0 is an interactive standalone application for the automatic segmentation and quantification of gated short axis blood pool (Red Blood Cells – RBC) SPECT.
  • Cedars-Sinai Motion Correction (MoCo) protocol is an application for the automatic and manual correction of SPECT acquisition motion artifacts from gated and ungated projection datasets. Pattern matching and segmentation algorithms are used in conjunction to minimize motion error metrics over the set of acquired projections. The resulting motion corrected projections are then presented to the operator for validation or modification.

Benefits

Cedars QGS provides the following benefits:

  • Automatic generation of left ventricle (LV) inner and outer surfaces and valve plane from LV short axis perfusion SPECT.
  • Two-dimensional display of short axis SPECT images in single or dual mode.
  • Computation of functional metrics including LV volume/time curve, ED (enddiastolic) volume, ES (end systolic) volume, EF (ejection fraction), mid-myocardial surface area, SMS (summed motion score) and STS (summed thickening score).
  • Automatic generation of surfaces and polar maps, which display in parametric fashion the pattern of thickening, regional EF, motion and perfusion of the LV.
  • Versatile display modes including interactive 3D beating image displays.
  • Derivation of the global scores SMS (summed motion score) and STS (summed thickening score) from corresponding segmental scores.

Cedars QPS provides the following benefits:

  • 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 mode.
  • Automatic generation of user defined normal limits.
  • Normal files include: Sestamibi, dual isotope and thallium.
  • 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, which display in parametric fashion the pattern of LV myocardial perfusion. Determination and display of the severity and extent of perfusion defects using isotope- and gender-specific normal limits.
  • 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).
  • Total perfusion Deficit (TPD) – measure of the amount of extent and severity in a defect.
  • PFQ – new normal file comparison.

Cedars Blood Pool Gated SPECT provides the following benefits:

  • Automatic generation of left and right ventricular endocardial surfaces and valve planes from three-dimensional (3D) gated short axis blood pool images.
  • Automatic calculation of left and right ventricular volumes and ejection fraction.
  • Two-dimensional (2D) image display using standard American College of Cardiology (ACC) cardiac SPECT conventions.
  • 3D image display including the ability to combine isosurfaces extracted from the data with the calculated endocardial surfaces in various ways. Endocardial borders can be displayed as wireframes, shaded surfaces or both.
  • Supports manual identification of left ventricular (LV) region in cases where the automatic algorithm fails to separate it from the right ventricular (RV) region or returns unsatisfactory results.
  • Ability to rotate, zoom and cine 3D surfaces.
  • Calculation and display of polar maps representing wall motion.

Cedars-Sinai Motion Correction provides the following benefits:

  • Fully automated protocol.
  • Integrated in to the Myovation Cardiac Tomography Package.
  • Advanced motion detection algorithm corrects all types of motion.
