The description focuses on traditional image processing techniques like registration, segmentation based on signal intensity, and parametric fitting, without mentioning AI or ML.
No
Explanation: The device is a post-processing software that assists in viewing, analyzing, and planning for medical procedures based on MRI data. It provides information for screening, diagnosis, intervention planning, and monitoring, but explicitly states that "Patient management decisions should not be made based solely on the results of DynaCAD analysis." It is not directly involved in treating or preventing disease.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device "provides information that may be useful in screening, diagnosis, intervention planning and monitoring." This directly indicates its role as a diagnostic device.
No
The device description explicitly states that the system consists of proprietary software installed on an "off-the-shelf personal computer and a monitor configured as a DynaCAD display station." While the core functionality is software, the system includes and relies on specific hardware components (computer and monitor) for its operation and display.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- DynaCAD's Function: DynaCAD is a software package that processes and analyzes imaging data (MRI studies) acquired from the patient's body. It does not analyze biological samples taken from the body.
- Intended Use: The intended use clearly states it's for "viewing and analyzing magnetic resonance imaging (MRI) studies." This is image processing, not in vitro testing.
Therefore, DynaCAD falls under the category of medical image processing software, not an in vitro diagnostic device.

Intended Use / Indications for Use
DynaCAD is a post-processing software package intended for use in viewing and analyzing magnetic resonance imaging (MRI) studies. DynaCAD V1.0 supports evaluation of dynamic MR data acquired during contrast administration. DynaCAD automatically registers serial patient image acquisitions to minimize the impact of patient motion, segments and labels tissue types based on enhancement characteristics (parametric image maps), and performs other user-defined post-processing functions (image subtractions, multiplanar reformats, maximum intensity projections). The resulting information can be displayed in a variety of formats, including a parametric image overlaid onto the source image. DynaCAD is designed to provide a reliable means of visualizing the presence and pattern of contrast induced enhancements of MRI data sets. DynaCAD also provides an intervention planning tool (DynaLOC) which assists with MRI guidance of percutaneous interventional procedures.
When interpreted by a skilled physician, this device provides information that may be useful in screening, diagnosis, intervention planning and monitoring. DynaCAD can also be used to provide accurate measurements of the diameters, areas, volumes and uptake characteristics of segmented tissues. Patient management decisions should not be made based solely on the results of DynaCAD analysis.

Device Description
DynaCAD image analysis relies on the assumption that pixels having similar MRI signal intensities represent similar tissues. The DynaCAD software simultaneously analyzes the pixel signal intensities from multiple MRI sequences and applies parametric fitting methods to perform tissue segmentation and classification.
