  1. Picture and Archiving Communication Systems (PACS) Lecture 18 Thursday, March 29 Victoria Aceti

  2. Picture and archiving information system • Original PACS system integrated in 1982 in the US • Allows for sharing of diagnostic images through a centralized repository • Different types of health information available in PACS: • Radiology • Cardiovascular What is PACS?

  3. SAH IMAGING GHC MAMMOGRAPHY RIS WS WS ARCHIVE REPORT RADIOLOGIST RIS

  4. Replacement of hard copy medical images • Remote access • Electronic integration of information (EMR & RIS) • Improvement of workflow • Additional tools to improve patient diagnoses • Improved collaboration • Improved communication Benefits of PACS

  5. Technical issues impeding the delivery of images • Potential loss of data or lack of data transmission • Legal issues of responsibility between organizations • High cost of integrating system and updating system PACS Challenges

  6. Originally the “Pan-Northern Ontario PACS Project” • NEODIN is one of four Diagnostic Imaging Repositories being implemented in Ontario • NW-LHIN, NE-LHIN & Champlain LHIN • A total of 59 hospitals (including Group Health Centre) involved • Overall goal is to link up all 4 in Ontario for one repository Pan-Northern Ontario PACS Project

  7. SAH IMAGING GHC MAMMOGRAPHY WS WS ARCHIVE REPORT RADIOLOGIST RIS

  8. Computer Assisted Diagnosis

  9. Computer Assisted Diagnosis • Combines artificial intelligence and digital images to help diagnose irregularities • Used in the detection of cancers and heart disease at the screening stage • Introduced in 1960s who proposed the idea that computers could detect irregularities

  10. Eadie et al. Systematic Review • Systematic review conducted in 2011 found that CADx assist in the diagnosis of breast cancers, but no evidence of overall benefit from using CADx. Further there is no evidence that CADx are a detriment to diagnosis
