Intended Use
QPlaque MR is a post-processing software application that is intended to assist trained cardiologists and radiologists in the assessment of atherosclerosis. The software is intended in particular to aid in assessing vessel wall thickness and remodeling in the carotid arteries I OPlaque MR post-processes multi-spectral MR images to semi-automatically determine the boundaries of the lumen and outer vessel wall, and provides editing tools for manual drawing of plaque components. The software enables area and volume measurements of the vessel wall as well as quantification of user-indicated areas. QPlaque MR results can be used to support the decision-making process in clinical practice and to support conclusions in clinical trials.
Device Description
QPlaque MR is able to read DICOM MR images from all major MR vendors. Vessel analysis data, generated by semi-automatic segmentation, detected stenosis and quantitative results can be saved in separate files enabling the comparison of results from different users. Radiologists, cardiologists and technicians use the QPlaque MR analytical software package to obtain objective and reproducible results. The obtained results may be used to support the interpretation of MR data, or they are used in the evaluation of follow-up studies and the effectiveness of treatment. In clinical practice QPlaque MR is used on workstations in review rooms or integrated in a PACS environment.

No
The summary describes "semi-automatic segmentation" and "post-processing software" but does not mention AI, ML, deep learning, or any related terms. The description focuses on image processing and measurement tools, not adaptive or learning algorithms.

No
The device is a post-processing software intended to assist in the assessment of atherosclerosis and support decision-making, not to directly treat a condition.

Yes
The device is a post-processing software that aids in the assessment of atherosclerosis, specifically vessel wall thickness and remodeling. It helps semi-automatically determine boundaries and provides measurements, supporting decision-making in clinical practice and facilitating the interpretation of MR data, all of which fall under diagnostic applications.

Yes

The device is explicitly described as a "post-processing software application" and "analytical software package" that operates on existing MR images. There is no mention of any accompanying hardware component being part of the device itself.

Based on the provided information, no, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
  • QPlaque MR's Function: QPlaque MR is a software application that processes medical images (MR images) of the carotid arteries. It does not analyze biological samples taken from the body.
  • Intended Use: The intended use is to assist in the assessment of atherosclerosis by analyzing vessel wall thickness and remodeling based on MR images. This is image analysis, not in vitro testing.

Therefore, QPlaque MR falls under the category of medical image processing software, not In Vitro Diagnostics.

N/A

Intended Use / Indications for Use

The QPlaque MR software performs quantitative analyses of the vessel wall and of plaque components in MR studies of atherosclerotic arteries. The quantitative analyses are based on semi-automatic segmentation of the MR studies. QPlaque quantifies vessel wall and plaque volumes, determines vessel wall thickness of the fibrous cap, and characterizes the plaque components.

QPlaque MR is intended for use by cardiologists or radiologists as an auxiliary tool in assessing atherosclerotic vessels. Its results may be used to support the decision-making process in clinical practice and to support conclusions in clinical trials.

Dear Mr. Hollander:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Image /page/2/Picture/10 description: The image shows a circular logo with the text "1906-2006" at the top and "Centennial" at the bottom. The letters "FDA" are prominently displayed in the center of the logo. Three stars are located below the word "Centennial". The logo appears to be a commemorative emblem for the centennial of the FDA.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at one of the following numbers, based on the regulation number at the top of this letter.
