Expanded applications of CT - Helical scanning in five common acute conditions

Recent years have witnessed notable improvements brought on by the latest g eneration of computed tomography (CT): helical (spiral) scanning. Although this technology holds significant advantages over conventional modalities, its use in mainstream medicine can be enhanced by thoughtful consideration of the challenges and opportunities it poses.
