With the help of advanced technological improvements over the past several years, the use of Picture Archiving and Communication System in the medical field can now be pushed even further. Several advanced features of PACS are being introduced, making PACS data storage even more functional. We are going to take a brief look at these advanced features in this article. The most prominent advancement added to PACS is the ability to search and recognize similar medical cases from existing records. If a patient is suffering from certain symptoms and doctors are having difficulties making proper diagnostics, the acquired medical images can be used as base to search for similar cases through the entire PACS server. Various recognition algorithms are used to enable this particular advanced feature. Another interesting advanced feature of today’s PACS is the ability to pre-fetch related studies based on keywords and diagnostic results. This makes deciding the best treatment to give even easier to do since doctors will have all the related information at their fingertips thanks to PACS. Not only will PACS help improve the overall workflow of a medical institution, it can also support doctors in doing their jobs and help save more lives for sure.
