Yes
The device description explicitly mentions "expert system image interpretation," which is a form of AI.
No
The device is a software program used for quantification and display of myocardial perfusion and left-ventricular function parameters, and for providing diagnostic and prognostic information. It does not exert any direct therapeutic action on the patient.
Yes
The device quantifies myocardial perfusion, displays wall motion, and quantifies left-ventricular function parameters from SPECT studies, which are diagnostic indicators for cardiac health. Additionally, it provides "computer assisted visual scoring, prognostic information, expert system image interpretation, and patient specific 3D coronary overlay," which are all related to providing information for diagnosis or prognosis.
Yes
The device description explicitly states it is a "software program" and describes its function as processing and displaying data from existing imaging studies. It runs on existing nuclear medicine computer systems and does not include any proprietary hardware.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body (like blood, urine, tissue). This device analyzes images of the human body (gated SPECT myocardial perfusion studies).
- The intended use and device description clearly state that it processes and quantifies data from medical imaging. It's used for analyzing myocardial perfusion, wall motion, and left-ventricular function parameters from SPECT scans.
- There is no mention of analyzing biological samples.
Therefore, this device falls under the category of medical imaging software or a medical device used in conjunction with imaging equipment, not an IVD.
No
The input letter does not explicitly state that the FDA has reviewed and approved or cleared a PCCP for this specific device.
Intended Use / Indications for Use
The Emory Cardiac Toolbox™ (CEqual®, EGS™) 2.0 software program should be used for the quantification of myocardial perfusion (CEQual®) and for the display of wall motion and quantification of left-ventricular function parameters from gated Tc99m SPECT myocardial perfusion studies (EGS™).

Device Description
The Emory Cardiac Tool Box™ 2.0 is used to display gated wall motion and for quantifying parameters of left-ventricular from gated SPECT myocardial perfusion studies. These parameters are: ejection fraction, end-diastolic volume, end-systolic volume, myocardial mass and transient ischemic dilatation (TID). In addition, the program offers the capability of providing the following diagnostic information: computer assisted visual scoring, prognostic information, expert system image interpretation, and patient specific 3D coronary overlay. This program was developed to run in the IDL operating system environment which can be executed on any nuclear medicine computer systems which supports IDL and the Aladdin (General Electric) software development . The program processes the studies automatically, however, user verification of output is required and manual processing capability is provided.

Safety and Effectiveness
1. Medical Device Establishment:
Emory University Voice: (404) 712-7422 (404) 712-7961 FAX: Contact person: Ernest Garcia, Ph.D. Date Summary Prepared: July 2, 1999
2. Medical Device:
Emory Cardiac Tool Box™ 2.0 - Display and Processing program for gated SPECT myocardial perfusion studies executing on nuclear medicine computer systems.
3. Medical Device Eguivalence:
Emory Cardiac Tool Box™ (CEqual®, EGS™) Version 1.0, Ref. 510(k) #: K980914.
4. Device Description:
The Emory Cardiac Tool Box™ 2.0 is used to display gated wall motion and for quantifying parameters of left-ventricular from gated SPECT myocardial perfusion studies. These parameters are: ejection fraction, end-diastolic volume, end-systolic volume, myocardial mass and transient ischemic dilatation (TID). In addition, the program offers the capability of providing the following diagnostic information: computer assisted visual scoring, prognostic information, expert system image interpretation, and patient specific 3D coronary overlay. This program was developed to run in the IDL operating system environment which can be executed on any nuclear medicine computer systems which supports IDL and the Aladdin (General Electric) software development . The program processes the studies automatically, however, user verification of output is required and manual processing capability is provided.
- Intended Use and Potential Adverse Effect on Health:
The intended use of this program was to provide the physician with a program which would allow him to display wall motion and determine measurements of ejection fraction and ventricular volumes from his patients gated SPECT myocardial perfusion study, obtain visual interpretation scores, prognostic information, expert system interpretation, and
1
coronary overlay onto 3D perfusion images. This program serves merely as a display and processing program to aid in the diagnostic interpretation of a patients' study. It was not meant to replace or eliminate the standard visual analysis of the gated SPECT study. The physician should integrate all of the patients' clinical and diagnostic information, i.e. patients' history, stress and/or rest EKG, quality control images, visual interpretation of the gated tomographic images, and quantitative results, prior to making his final interpretation. This comprehensive processing technique (as with all diagnostic imaging) is not perfect, and will be associated with some false positive and false negative results. The expected accuracy of the program can be found in the multicenter trial results listed in the article by Vansant et al (See Item H, Testing & Validation) and the physician should be aware of the accuracy when integrating the quantitative results for his final interpretation. Therefore, this program has no direct adverse effect on health since the results represent only a part of the information which the physician will utilize for his final interpretation. The final responsibility for interpretation of the study lies with the physician.
6. Marketing History:
There have been several medical device gated SPECT programs marketed in the past which perform similar functions to those performed by the Emory Cardiac Tool Box™ 2.0. These programs are all used for the purpose of displaying wall motion and deriving functional parameters for the diagnostic interpretation by a physician. The Emory Cardiac Tool Box™ 2.0 provides a program which executes in the IDL operating system environment and we believe is substantially equivalent to our previous version of the Emory Cardiac Tool Box™ (CEqual®, EGS™), K980914. To our knowledge there have been no safety problems with the Emory Cardiac Tool Box™ (CEqual®). EGS™) program which has been in the marketplace for over seven months.
7. Conclusions:
The safety of this program has been determined through the various stages of software development which included the initial design, coding, debugging, testing, and validation. The effectiveness of the program has been established in phantom and computer simulations studies, in-house trial validations which included an evaluation of left ventricular functional parameter calculations in 217 patients, and in a multicenter trial validation consisting of 80 patients. In addition, the computer assisted visual scoring, prognosis, expert system, and coronary fusion algorithms were successfully evaluated in 20, 504, 461, and 9 patients respectively. Specific details and results concerning the validation of the Emory Cardiac Tool Box™ 2.0 program are listed in Item F, Testing & Validation. We contend that the method employed for the development and the final in-house and multicenter trial validation results of this medical display software program, Emory Cardiac Tool Box™ 2.0, have proven its safety and effectiveness. In our opinion the Emory Cardiac Tool Box™ 2.0 is substantially equivalent to our previous version of the Emory Cardiac Tool Box™ (CEqual®, EGS™) which has been cleared for marketing. The Emory Cardiac Tool Box™ 2.0 is intended for the same purpose and raises no new issues of safety or effectiveness.
