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 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• PowerPoint and other types of presentations

MIRC Components

• Query ServiceEntry point into the MIRC community for a user on the InternetQuery 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 standards-based 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
