Association of Pre-Diabetes and type 2 diabetes mellitus with intracranial plaque characteristics in patients with acute ischemic stroke
CONCLUSIONS: Patients with pre-diabetes and T2DM had similar intracranial atherosclerotic plaque vulnerability, as demonstrated by multiple plaques, increased culprit plaque enhancement ratio and global plaque enhancement score.ADVANCES IN KNOWLEDGE: Pre-diabetes might be a risk factor for intracranial plaque vulnerability. It is necessary to monitor a slight increase in blood glucose in non-diabetes patients with acute ischemic stroke.PMID:36350061 | DOI:10.1259/bjr.20220802

Association of dissection features and primary collateral circulation with ischemic stroke in patients with spontaneous internal carotid artery dissection: Evaluated using vessel Wall-MRI and MRA
CONCLUSIONS: Both the poor primary collateral circulation and severe stenosis may play important role in occurrence of ischemic stroke for spontaneous ICAD patients and good primary collateral circulation can help to reduce the incidence of infarction.ADVANCES IN KNOWLEDGE: ICAD is one of the major causes of ischemic stroke. Early evaluation of the status of the Circle of Willis in ICAD patients by MRI may help to make treatment strategies and improve clinical outcome.PMID:35816551 | DOI:10.1259/bjr.20210845

Multidelay ASL of the pediatric brain
Br J Radiol. 2022 Apr 22:20220034. doi: 10.1259/bjr.20220034. Online ahead of print.ABSTRACTArterial spin labeling (ASL) is a powerful noncontrast MRI technique for evaluation of cerebral blood flow (CBF). A key parameter in single-delay ASL is the choice of postlabel delay (PLD), which refers to the timing between the labeling of arterial free water and measurement of flow into the brain. Multidelay ASL (MDASL) utilizes several PLDs to improve the accuracy of CBF calculations using arterial transit time (ATT) correction. This approach is particularly helpful in situations where ATT is unknown, including young subjects and...

The impact of brain atrophy on the outcomes of mechanical thrombectomy
CONCLUSIONS: The few studies available highlight heterogeneity of neuroimaging methodologies for assessing brain atrophy and difficulty addressing the multiple confounders involved in clinical outcomes. More consistent, accurate investigation is needed before proposing brain atrophy as a possible parameter to improve patient selection for MT.ADVANCES IN KNOWLEDGE: Brain atrophy is associated with many of the clinical confounders frequently present in patients with acute ischemic stroke. Heterogeneity in classification methodologies for brain atrophy and complexity analyzing multiple clinical confounders make it difficult t...
