Journal ArticleDOI

Penumbral imaging and functional outcome in patients with anterior circulation ischaemic stroke treated with endovascular thrombectomy versus medical therapy: a meta-analysis of individual patient-level data

Bruce C.V. Campbell, +1296 more
- 01 Jan 2019 - 
TL;DR: Estimated ischaemic core volume was independently associated with functional independence and functional improvement but did not modify the treatment benefit of endovascular thrombectomy over standard medical therapy for improved functional outcome.
Journal ArticleDOI

Vertebral compression fracture (VCF) after spine stereotactic body radiation therapy (SBRT): analysis of predictive factors.

TL;DR: The presence of kyphotic/scoliotic deformity and the presence of lytic tumor were the only predictive factors of VCF based on the original 6 SINS criteria and patients with lung and hepatocellular tumors and treatment with SBRT of 20 Gy or greater in a single fraction are at a higher risk of V CF.
Journal ArticleDOI

Certainty of stroke diagnosis: incremental benefit with CT perfusion over noncontrast CT and CT angiography

TL;DR: An incremental stroke protocol that includes CT perfusion increases diagnostic performance for stroke diagnosis and inter- and intraobserver agreement.
Journal ArticleDOI

Characterization of Carotid Plaque Hemorrhage A CT Angiography and MR Intraplaque Hemorrhage Study

TL;DR: CT angiographic features that are able to predict the presence of intraplaque hemorrhage (IPH) as defined by MR-IPH were evaluated and CTA plaque ulceration was useful for prediction of IPH.
Journal ArticleDOI

Interobserver Agreement of ASPECT Score Distribution for Noncontrast CT, CT Angiography, and CT Perfusion in Acute Stroke

TL;DR: CTP-CBV demonstrates the highest interobserver agreement for individual ASPECTS regions, and highest concordance was shown for caudate, lentiform, and M1–M3, whereas performance for internal capsule and M4–M6 was poorer.
