Teleradiology provides a cost-effective way to deliver radiology services by taking advantage of differences in time zones and pooling radiologist resources across multiple centers. It can help address issues like increasing imaging volumes, radiologist shortages, and the need for emergency or second opinions in remote locations. However, there are barriers to adoption like technology requirements, credentialing radiologists remotely, malpractice liability, reimbursement challenges, and ensuring compliance with healthcare regulations and standards.
