Intended Use

CADstream is intended to be used in the visualization, analysis, and reporting of magnetic resonance imaging (MRI) studies. CADstream supports evaluation of dynamic MR data acquired during contrast administration. CADstream performs other user selected processing functions (such as image registration, subtractions, measurements, 3D renderings, and reformats). CADstream also includes user-configurable features for reporting on findings in breast or general MRI studies. Additionally, CADstream assists users in planning MRI guided interventional procedures. When interpreted by a skilled physician, this device provides information that may be used for screening, diagnosis, and interventional planning. Patient management decisions should not be made based solely on the results of CADstream. CADstream may also be used as an image viewer of multi-modality, digital images, including ultrasound and mammography. CADstream is not intended for primary interpretation of digital mammography images.

Device Story

CADstream Version 5 is an image processing system for MRI studies. It receives DICOM images from PACS or MRI scanners; processes data on a server or client PC; and provides tools for visualization (MIPs, reformats), analysis (registration, subtraction, kinetic curves, parametric maps, 3D rendering), and reporting. Used by radiologists/physicians in clinical settings to assist in screening, diagnosis, and interventional planning. Output includes processed images, kinetic analysis, and reports. Benefits include improved workflow efficiency and standardized reporting. Patient management decisions must not rely solely on device output.

Clinical Evidence

Bench validation testing performed to verify device meets input requirements and demonstrate substantial equivalence to version 4. Clinical validation testing conducted to demonstrate conformance to user needs and intended uses per 21 CFR 820.30(g). No specific clinical trial metrics (e.g., sensitivity/specificity) provided.

Technological Characteristics

Image processing software installed on off-the-shelf computer hardware. Features include DICOM connectivity, image registration, subtraction, kinetic curve analysis, parametric mapping, and 3D volume rendering. Operates as a networked system for visualization and reporting.

Indications for Use

Indicated for visualization, analysis, and reporting of MRI studies, including dynamic contrast-enhanced data, in patients undergoing breast or general MRI. Assists in interventional planning. Also functions as a multi-modality image viewer for ultrasound and mammography (not for primary interpretation). Intended for use by skilled physicians.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

Dear Mr. Lewis:

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. Ilsting 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 (PMA), 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.
