Rex N, McDonough R, Ospel J, Kashani N, Sehgal A, Fladt J, et al.
AJNR Am J Neuroradiol
. 2023 Aug;
44(9):1045-1049.
PMID: 37620153
Background And Purpose: Although reperfusion is associated with improved outcomes in patients with acute ischemic stroke undergoing endovascular treatment, many patients still do poorly. We investigated whether CTP modifies the...

Cimflova P, McDonough R, Kappelhof M, Singh N, Kashani N, Ospel J, et al.
AJNR Am J Neuroradiol
. 2021 Oct;
42(12):2188-2193.
PMID: 34711552
Background And Purpose: Thrombus embolization during mechanical thrombectomy occurs in up to 9% of cases, making secondary medium vessel occlusions of particular interest to neurointerventionalists. We sought to gain insight...

McDougall C, Chan L, Sachan S, Guo J, Sah R, Menon B, et al.
AJNR Am J Neuroradiol
. 2020 Oct;
41(11):2034-2040.
PMID: 33004342
Background And Purpose: Infarct core volume measurement using CTP (CT perfusion) is a mainstay paradigm for stroke treatment decision-making. Yet, there are several downfalls with cine CTP technology that can...

Almekhlafi M, Kunz W, McTaggart R, Jayaraman M, Najm M, Ahn S, et al.
AJNR Am J Neuroradiol
. 2019 Dec;
41(1):129-133.
PMID: 31806593
Background And Purpose: The role of collateral imaging in selecting patients for endovascular thrombectomy beyond 6 hours from onset has not been established. To assess the comparative utility of collateral...

Yogendrakumar V, Al-Ajlan F, Najm M, Puig J, Calleja A, Sohn S, et al.
AJNR Am J Neuroradiol
. 2019 Mar;
40(4):655-660.
PMID: 30872416
Background And Purpose: Intracranial hemorrhage is a known complication following endovascular thrombectomy. The radiologic characteristics of a CT scan may assist with hemorrhage risk stratification. We assessed the radiologic predictors...

Almekhlafi M, Kunz W, Menon B, McTaggart R, Jayaraman M, Baxter B, et al.
AJNR Am J Neuroradiol
. 2019 Feb;
40(3):396-400.
PMID: 30705072
The overwhelming benefit of endovascular therapy in patients with large-vessel occlusions suggests that more patients will be screened than treated. Some of those patients will be evaluated first at primary...

Qiu W, Kuang H, Nair J, Assis Z, Najm M, McDougall C, et al.
AJNR Am J Neuroradiol
. 2018 Dec;
40(1):39-44.
PMID: 30573458
Background And Purpose: Thrombus characteristics identified on non-contrast CT (NCCT) are potentially associated with recanalization with intravenous (IV) alteplase in patients with acute ischemic stroke (AIS). Our aim was to...

Kuang H, Najm M, Chakraborty D, Maraj N, Sohn S, Goyal M, et al.
AJNR Am J Neuroradiol
. 2018 Dec;
40(1):33-38.
PMID: 30498017
Background And Purpose: Alberta Stroke Program Early CT Score (ASPECTS) was devised as a systematic method to assess the extent of early ischemic change on noncontrast CT (NCCT) in patients...

AJNR Am J Neuroradiol
. 2017 Dec;
39(1):102-106.
PMID: 29191873
Background And Purpose: The safety and efficacy of endovascular therapy for large-artery stroke in the extended time window is not yet well-established. We performed a subgroup analysis on subjects enrolled...

AJNR Am J Neuroradiol
. 2017 Nov;
39(1):107-110.
PMID: 29170266
Background And Purpose: Endovascular therapy has become the standard of care for patients with disabling anterior circulation ischemic stroke due to proximal intracranial thrombi. Our aim was to determine whether...
