The summary describes standard MRI imaging techniques and image processing methods (subtraction, filtering) without mentioning any AI or ML algorithms. The focus is on a new pulse sequence.
No
The device is described as an "imaging device" and a "dedicated breast MRI system intended to be used as an adjunct to conventional breast screening methods" to provide "information that can be useful in diagnosis determination," indicating a diagnostic rather than therapeutic purpose.
Yes
The "Intended Use / Indications for Use" section explicitly states, "When interpreted by a trained physician. these images provide information that can be useful in diagnosis determination." and "The AURORA is a dedicated breast MRI system intended to be used as an adjunct to conventional breast screening methods." and "Diagnostic uses: 2D, 3D T1-/T2-weighted imaging."
No
The device is described as an "imaging device" and an "MRI system," which are hardware-based modalities. The modification is the addition of a "pulse sequence," which is a software component, but it's added to an existing hardware system.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood and tissue donations, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to determine the compatibility of donations with potential recipients, or to monitor therapeutic measures.
- AURORA MRI System Function: The AURORA MRI system is an imaging device. It works by using magnetic fields and radio waves to create images of the internal structure of the body. It does not examine specimens in vitro (outside the body).
- Intended Use: The intended use clearly states it's an "imaging device" that provides "physiological and clinical information obtained noninvasively". This is characteristic of an imaging modality, not an IVD.
The device description and intended use clearly indicate that this is a medical imaging system used for diagnostic purposes in vivo (within the body), not an IVD.
N/A
Intended Use / Indications for Use
The AURORA MRI system is an Imaging device, and is intended to provide the physician with physiological and clinical information obtained non-invasively and without the use of lonizing radiation. The MR system produces transverse, coronal, sagittal, and oblique cross-sectional images that display the internal structure of the extremities (breast tissue, axilla, and chest wall local to the breast). The images produced by the MR system reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The NMR properties that determine the image appearance are proton density spin-lattice relaxstion time (T1), spin-spin relaxation time (T2), and flow. When interpreted by a trained physician, these images provide information that can be useful in diagnosis determination.
The AURORA is a dedicated breast MRI system intended to be used as an adjunct to conventional breast screening methods.
- Anatomical region: Breast tissue, axilla, and chest wall local to the breast
- Nucleus excited: Proton
- Diagnostic uses: 2D, 3D T1-/T2-weighted imaging.

§ 892.1000 Magnetic resonance diagnostic device.
(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

6. TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE
Aurora Imaging Technology, Inc., makes a claim of substantial equivalence of the modified AURORA to the predicate AURORA (K032082) based on similarities in intended use, design, and technological and operational characteristics. Both are indicated for magnetic resonance imaging of the breast. Both systems use the same hardware and software except that the modified device includes a new pulse sequence for RODEO Spiral 3D.
7. Testing
Testing was performed to validate the safety and performance of the AURORA with the new pulse sequence.
