Laboratory and imaging

Teleradiology

Teleradiology is the electronic transmission of medical images, such as X ray and CT studies, from the place where they are acquired to a radiologist elsewhere, who interprets them and returns a report to the treating clinician.

Why it matters

Many hospitals have imaging equipment but no radiologist on site, and radiologists are often concentrated in capital cities. Teleradiology lets a district or provincial hospital obtain a specialist report without transferring the patient. A review of teleradiology systems in Africa evaluated current and former programmes and the factors that affected whether they lasted [1].

Key points

  • Studies are sent in DICOM from the hospital PACS to the reporting radiologist [2].
  • Turnaround time from acquisition to report is the key measure of service, and it should be agreed and monitored for routine and urgent studies separately.
  • The report must return to the requesting clinician and the patient record.
  • Charitable and partnership programmes, such as RAD AID's global radiology programme, provide remote reporting for hospitals with limited access to radiologists [3].

In Moana

MOANA PACS gives remote radiologists a browser viewer and worklist, and their reports return to the requesting clinician in the patient record.
