Intended Use
Precedence is an imaging system combining the acquisition of single photon nuclear medicine images and images from an x-ray computed tomography system. The x-ray computed tomography subsystems may consist of a whole body multi-slice CT or cardiovascular CT. The cardiovascular subsystem provides coronary imaging that is intended to produce cross-sectional images of the heart, cardiovascular, and peripheral vascular systems by computer reconstruction of x-ray transmission data taken at difference angles and planes. Precedence may produce non-attenuation corrected and attenuation corrected images of the distribution of radiopharmaceuticals in the body as well as x-ray transmission images. The CT transmission data may be used to produce attenuation corrected nuclear medicine images. The nuclear medicine images and the CT images may be registered and displayed in a fused format (overlaid in the same orientation) to provide combined single photon and anatomical data for anatomical localization of the nuclear medicine data. Precedence may be used either as a separate single photon system, a separate CT system or as a combined CT and single photon system. The nuclear medicine and CT images may be transferred to other systems such as a radiation therapy planning system. The Precedence Imaging System should only be used by trained healthcare professionals. The Precedence CV Configuration CT subsystem is only for the imaging of the cardiovascular system.
Device Description
The Precedence SPECT/CT Imaging System is a hybrid SPECT/CT system for performing CT studies, general nuclear medicine studies, or SPECT/CT sequentially (dual-modality studies) wherein the SPECT and CT studies may be automatically coregistered and displayed in fused form. Because the natures of the imaging modalities, they provide different information; the SPECT study yields functional information about metabolic processes and the CT study yields structural or anatomical information. As radionuclides become more tissue specific, diagnoses from nuclear images alone will be more difficult without the general anatomical detail less specific agents provide. Thus fused SPECT and CT images will provide the information required for accurate and comprehensive diagnoses. Precedence is constructed from two existing systems, the Skylight SPECT Imaging System and the Brilliance CT with subsystem options of 6, 16, or 64 slice or the CVCT configuration. The Precedence has two acquisition consoles. One console is placed in the acquisition room itself, consistent with the SPECT convention, and the other console is placed in the shielded scanner control room, as required for CT. The acquisition stations provide a single user interface for both SPECT and CT patient acquisition set-up. The SK Ylight and Brilliance system gantries remain intact as major subsystem components located within a common integrated housing. The combined Precedence SPECT-CT Imaging System is designed so that the system can operate in three modes: CT only, SPECT only, and combined SPECT/CT performed sequentially. No modifications have been made to either system, which would affect system performance. Precedence is intended for use primarily as an imaging system combining the acquisition of single photon nuclear medicine images and images from an x-ray computed tomography system. The clinical protocols and procedures are that are available on the modified Precedence Imaging System are the same as those on the Predicate Devices Precedence SPECT/CT (cleared as Griffin) (K041218), Predicate Philips Plus CT Scanner (K033326), and the Brilliance CT, Private Practice CV configuration CT Scanner (K042293). The intended use of the CV configuration CT Scanner is limited to the heart, cardiovascular, and peripheral vascular systems. Acquired SPECT and CT images on the Precedence may be registered and displayed in a fused format (overlaid in the same orientation) to provide combined single photon and anatomical data to provide anatomical localization of the nuclear medicine image. The Precedence CV Configuration CT subsystem is not indicated for imaging structures that are defined as non-cardiac and non-vascular (including soft tissue and bone).
More Information

Not Found

No
The summary describes a hybrid imaging system combining existing SPECT and CT technologies with image registration and fusion capabilities. There is no mention of AI or ML in the intended use, device description, or performance studies.

No
The device is described as an imaging system used for diagnosis, not for treatment.

Yes

This device combines SPECT and CT imaging to provide functional and anatomical information for accurate and comprehensive diagnoses. The output is used to localize nuclear medicine data and aid in diagnosis.

No

The device description clearly states it is a "hybrid SPECT/CT system" and describes physical components like gantries and acquisition consoles, indicating it is a hardware-based imaging system with integrated software.

Based on the provided text, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs analyze samples taken from the human body (like blood, urine, tissue) outside the body. The Precedence system is an imaging system that acquires images of the human body using nuclear medicine and CT technology.
  • The intended use and device description clearly state that it is an imaging system. It produces images of the distribution of radiopharmaceuticals and x-ray transmission data to visualize anatomical structures and functional processes within the body.
  • There is no mention of analyzing biological samples or performing tests on specimens.

The Precedence system is a medical imaging device used for diagnostic purposes, but it falls under the category of in vivo imaging, not in vitro diagnostics.

Comparison to Predicate Device: G.

The modified Precedence SPECT/CT Imaging System and the Precedence predicate (K041218) are similar in that all the devices consist of a full functional SPECT and CT system. The patient may have a diagnostic SPECT and CT scan performed consecutively without having to move the patient. The Precedence provides a mean to reach the diagnostic decision faster than the conventional way of imaging patients with both SPECT and CT systems in separate locations.

The combined Precedence SPECT-CT Imaging System is designed so that the system can operate in three modes: CT only, SPECT only, and combined SPECT/CT performed sequentially. The major difference is that the modified Precedence has added the CT subsystem options of the 64 slice and the CV configuration CT Scanner.

    • Electrical and mechanical safety is assured as the system is designed to applicable . voluntary standards in the IEC 60601-1 series. The device performance was measured in accordance with the NEMA-NU-1 standard.
