The document discusses the evolution of teleradiology from traditional radiology where everything occurred under one roof, to modern teleradiology where radiologists can remotely access and interpret images. It describes how teleradiology companies use systems like Clariso to simplify the integration between hospitals and radiology groups, allowing radiologists to receive images over DICOM, generate reports sent back over fax/DICOM/HL7, and providing features for ordering, scheduling, customized workflows, diagnostic viewing, and analytics.
