Moving From CT to MRI Paradigm in Acute Ischemic Stroke: Feasibility, Effects on Stroke Diagnosis and Long-Term Outcomes.

Although this resulted in a reduction in the median length of hospitalization from 9 days (IQR, 6–14) during the CT-paradigm to 7 days (IQR, 4–12) during the MRI-paradigm, the effect of the imaging paradigm did not reach statistical significance in the multivariable analysis (β coefficient, −0.27 [95% CI, −1.36 to 0.81]; P adj =0.62; Table 2 ).

We found a significant trend in the length of hospitalization over the study period, characterized by a linear reduction that was consistent across both imaging paradigms and reached a plateau in the second part of the MRI period paradigm (Figure 2 C).
