Indications for Use
nordicTumorEx is an image processing software package to be used by trained professionals including but not limited to physicians and medical technicians. The software runs on a standard "off-the-shelf" PC workstation and can be used to perform image viewing, processing and analysis of medical images. Data and images are acquired through DICOM compliant imaging devices and modalities. nordicTumorEx software enables processing and visualization of dynamic MR imaging datasets of the brain, showing properties of changes in contrast over time. It generates various parametric images calculated from the image intensity variations and provides tools to extract and visualize such parametric properties within specified volumes of interest. Structural datasets providing anatomical information can be used to evaluate the extent of a specified sub-volume, such as a tumor. Comparison of imaging studies performed at different study dates may also be performed to support the diagnostic process.
Device Story
nordicTumorEx is a post-processing software for dynamic contrast-enhanced (DCE) MRI brain data. It runs on standard Windows PC workstations. Input consists of DICOM-compliant dynamic MR imaging datasets. The software analyzes temporal signal intensity changes resulting from contrast agent bolus injections to calculate functional parameters, including tissue perfusion, blood volume, and capillary permeability. It generates parametric maps and allows visualization of these properties within user-defined volumes of interest. Structural MR images are integrated to assist in evaluating tumor extent. The software supports longitudinal comparison of studies. Used in clinical environments by physicians and medical technicians to support diagnostic processes by providing quantitative and visual data on tissue hemodynamics.
Clinical Evidence
Bench testing only. Verification and validation activities were performed to ensure the software meets design specifications and user needs.
Technological Characteristics
Post-processing software for dynamic MRI data; runs on standard off-the-shelf Windows PC workstations. Utilizes DICOM-compliant data input. Implements established mathematical models for calculating perfusion, blood volume, and capillary permeability from temporal signal intensity variations in DCE-MRI. Standalone software application.
Indications for Use
Indicated for trained professionals, including physicians and medical technicians, to perform viewing, processing, and analysis of DICOM-compliant dynamic MR imaging datasets of the brain. Used to visualize contrast changes over time, generate parametric images (perfusion, blood volume, capillary permeability), and evaluate sub-volumes such as tumors.
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.
