Venkatraghavan L, Rosen C, McKetton L, Poublanc J, Sobczyk O, Duffin J, et al.
Can J Neurol Sci
. 2023 Jan;
51(1):57-63.
PMID: 36624923
Background: In patients with intracranial steno-occlusive disease (SOD), the risk of hemodynamic stroke depends on the poststenotic vasodilatory reserve. Cerebrovascular reactivity (CVR) is a test for vasodilatory reserve. We tested...

Investigations of hypoxia-induced deoxyhemoglobin as a contrast agent for cerebral perfusion imaging
Sayin E, Schulman J, Poublanc J, Levine H, Raghavan L, Uludag K, et al.
Hum Brain Mapp
. 2022 Oct;
44(3):1019-1029.
PMID: 36308389
The assessment of resting perfusion measures (mean transit time, cerebral blood flow, and cerebral blood volume) with magnetic resonance imaging currently requires the presence of a susceptibility contrast agent such...

Physiol Rep
. 2022 Oct;
10(19):e15472.
PMID: 36200271
In patients with sickle cell disease (SCD), the delivery of oxygen to the brain is compromised by anemia, abnormal rheology, and steno-occlusive vascular disease. Successful compensation depends on an increase...

Front Physiol
. 2022 Sep;
13:886807.
PMID: 36060689
Despite increased cerebral blood flow (CBF), cerebral infarcts occur in patients with sickle cell disease (SCD). This suggests increased CBF does not meet metabolic demand possibly due to compromised cerebral...

. 2022 Jul;
261:119523.
PMID: 35907499
Cerebral blood arrival and tissue transit times are sensitive measures of the efficiency of tissue perfusion and can provide clinically meaningful information on collateral blood flow status. We exploit the...

. 2022 Feb;
98(14):e1446-e1458.
PMID: 35169007
Background And Objectives: Small iatrogenic brain infarcts are often seen on diffusion-weighted MRI (DWI) following surgical or endovascular procedures, but there are few data on their clinical effects. We examined...

Quant Imaging Med Surg
. 2021 Nov;
11(11):4530-4542.
PMID: 34737921
Background: Evidence suggests that cerebrovascular reactivity (CVR) increases within the first week after the incidence of concussion, indicating a disruption of normal autoregulation. We sought to extend these findings by...

. 2021 Oct;
86(6):3012-3021.
PMID: 34687064
Purpose: To demonstrate the feasibility of mapping cerebral perfusion metrics with BOLD MRI during modulation of pulmonary venous oxygen saturation. Methods: A gas blender with a sequential gas delivery breathing...
