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).
