Survey of Image Quality in Irish Stroke CT Protocols

      Non-contrast computed tomography (NCCT) of the brain is a critical tool in the investigation of suspected acute ischaemic stroke. The recognition of subtle differences in attenuation values between normal brain parenchyma and regions of ischaemic tissue may be crucial to accurate and timely diagnosis. Radiologists at MMUH have been concerned with inconsistencies in image quality received from the various scanners and hospitals. Our study aimed to investigate the variation in imaging protocols for suspected acute stroke at different institutions in the regional hospital network using an objective measure of low contrast detectability (LCD).
