Teleradiology - Telewhat?  One propose a segmentation:  Teleteaching  Telelearning  Teleexpertise  Teleconsultation  Telediagnosis  TeleXXX  My purpose: teleradiology in daily radiological practice (telediagnosis ± teleexpertise)  One propose a segmentation:  Teleteaching  Telelearning  Teleexpertise  Teleconsultation  Telediagnosis  TeleXXX  My purpose: teleradiology in daily radiological practice (telediagnosis ± teleexpertise)

Teleradiology - Why?  In some area there is a lack of radiologists.  Sometime it could be financially accurate to have only one radiologist on duty for several radiological facilities.  Boston experimentation: a contract with an Israeli and an Asian Hospitals to have only daytime reading.  Access to specialized expertise.  In some area there is a lack of radiologists.  Sometime it could be financially accurate to have only one radiologist on duty for several radiological facilities.  Boston experimentation: a contract with an Israeli and an Asian Hospitals to have only daytime reading.  Access to specialized expertise.

Teleradiology in France  Some applications dedicated to neurosurgery:  Point to point,  Specific,  Launched at the beginning of the nineties,  Expensive and not easy to use.  New projects dedicated to general radiology.  Some applications dedicated to neurosurgery:  Point to point,  Specific,  Launched at the beginning of the nineties,  Expensive and not easy to use.  New projects dedicated to general radiology.

Teleradiology in Cantal  Mountainous area: transportation difficulties (winter).  Lack of radiologists.  Three main hospitals in the département:  Only one have senior full time radiologists,  One have an half time radiologist,  The last one have only interim radiologists,  Frequency of duty is too high in each hospital.  Sometime specialized second advice could be necessary -> patient records have to be sent to university hospitals.  Mountainous area: transportation difficulties (winter).  Lack of radiologists.  Three main hospitals in the département:  Only one have senior full time radiologists,  One have an half time radiologist,  The last one have only interim radiologists,  Frequency of duty is too high in each hospital.  Sometime specialized second advice could be necessary -> patient records have to be sent to university hospitals.

The projects  Send examinations to “on duty” radiologist home.  One radiologist on duty for all three hospitals.  Along the day, ability to send examination from one hospital to another directly from daily used working tools to daily used working tools.  Simplicity of use.  Security.  Federate all imaging departments of the département to manage them as an unique entity.  Send examinations to “on duty” radiologist home.  One radiologist on duty for all three hospitals.  Along the day, ability to send examination from one hospital to another directly from daily used working tools to daily used working tools.  Simplicity of use.  Security.  Federate all imaging departments of the département to manage them as an unique entity.
