Medical Image Resource Center What is MIRC Medical

Medical Image Resource Center

What is MIRC? • “Medical Imaging Resource Center” • Makes it easier to locate and share electronic medical images and related information – On your PC – In your department – Throughout the world

MIRC: Why? • MIRC helps radiologists: – Create and manage teaching files and reference images for decision support – Participate in imaging clinical trials – Share research databases within institutions and across the imaging community

Key MIRC Concepts • Libraries cooperate by using a common mechanism to query one another • The MIRC query mechanism allows users to find information within these libraries • MIRC stores and displays documents in multiple formats

Key MIRC Concepts • Libraries cooperate by using a common mechanism to query one another • The MIRC query mechanism allows users to find information within these libraries • MIRC stores and displays documents in multiple formats

Key MIRC Concepts • Libraries cooperate by supporting a common query mechanism • A Query mechanism allows users to find information within these libraries • MIRC supports multiple information storage formats

MIRC Libraries • MIRC libraries archive a wide variety of text, images, and other multimedia information – Teaching files – Research and reference image repositories • Collection of disease-specific radiographs • Normal variants • Functional brain MR data sets • Clinical trials images and related data • Journal articles • Textbooks • Power. Point and other types of presentations

MIRC Components • Query Service Entry point into the MIRC community for a user on the Internet Query service is defined by its use of the MIRC query schema

MIRC Components • Storage Service: Cooperating information library – a web archive or a database, designed to support the MIRC query mechanism. • Index: The library’s card catalog of the contents of a storage service.

MIRC in Clinical Trials • MIRC provides non-proprietary standardsbased software for clinical trials, available free and open source • After extensive evaluation, the National Cancer Institute’s Cancer Imaging Program has selected MIRC for use in clinical trials

Other Ongoing Clinical Trials • WHIMS 1 -3 (Women's Health Initiative Memory Study) • WHI – Women’s Health Initiative CT Study • CARDIA - Coronary Artery Risk Development in Young Adults • RIDER - Reference Image Database to Evaluate Response to Therapy • CIREN – Crash Injury Research & Engineering Network – Wake Forest (PI) • CAMPS – Carotid Atherosclerosis MRI Progression Study – University of Washington (PI)

Research Dataset Acquisition • MIRC feature developed in collaboration with Mallinckrodt Institute of Radiology • Allows internal researchers to acquire DICOM images from modalities, store and manage them without using the clinical PACS – Bridges internal networks – Tracks access of PHI for HIPAA compliance

NCI Collaboration • Successful demonstration in early 2005 • Support of current trials (RIDER, LIDC) • Decision to use MIRC for clinical trials in the future • Development of MIRC extensions to support the NCI imaging database
