The authors evaluated 244 consecutive patients eligible for reperfusion therapy with MCA stroke and pretreatment MR imaging with both FLAIR and PWI. The FLAIR vascular hyperintensity score was based on ASPECTS, ranging from 0 (no FLAIR vascular hyperintensity) to 7 (FLAIR vascular hyperintensities abutting all ASPECTS cortical areas). The hypoperfusion intensity ratio was defined as the ratio of the time-to-maximum >10-second over time-to-maximum >6-second lesion volumes. The FLAIR vascular hyperintensities were more extensive in patients with good collaterals than those with poor collaterals. The FLAIR vascular hyperintensity score was independently associated with good collaterals. They conclude that the ASPECTS assessment of FLAIR vascular hyperintensities could be used to rapidly identify patients more likely to benefit from reperfusion therapy.

- EDITOR'S CHOICEHead and Neck ImagingOpen AccessDynamic Contrast-Enhanced MRI–Derived Intracellular Water Lifetime (τi): A Prognostic Marker for Patients with Head and Neck Squamous Cell CarcinomasS. Chawla, L.A. Loevner, S.G. Kim, W.-T. Hwang, S. Wang, G. Verma, S. Mohan, V. LiVolsi, H. Quon and H. PoptaniAmerican Journal of Neuroradiology January 2018, 39 (1) 138-144; DOI: https://doi.org/10.3174/ajnr.A5440
The authors evaluated 60 patients with dynamic contrast-enhanced MR imaging before treatment. Median, mean intracellular water molecule lifetime, and volume transfer constant values from metastatic nodes were computed from each patient. Kaplan-Meier analyses were performed to associate mean intracellular water molecule lifetime and volume transfer constant and their combination with overall survival and beyond. Patients with high mean intracellular water molecule lifetime had overall survival significantly prolonged by 5 years compared with those with low mean intracellular water molecule lifetime. Patients with high mean intracellular water molecule lifetime had significantly longer overall survival at long-term duration than those with low mean intracellular water molecule lifetime. Volume transfer constant was a significant predictor for only the 5-year follow-up period. They conclude that a combined analysis of mean intracellular water molecule lifetime and volume transfer constant provided the best model to predict overall survival in patients with squamous cell carcinomas of the head and neck.
