Enhancing turn-around-time (TAT) on stroke protocol head CT reports via continuous quality improvement (CQI) methodology in a busy teleradiology practice

open access: yesAmerican Journal of Experimental and Clinical Research, 2015
Through strict adherence to continuous quality improvement (CQI) methodology, over a 3 year period our teleradiology practice was able to achieve ongoing 100% compliance with our turn-around-time (TAT) goal for interpretation of stroke protocol head CTs.
