Presence and extent of coronary calcified plaque evaluated by coronary computed tomographic angiography are independent predictors of ischemic stroke in patients with suspected coronary artery disease
Abstract Although ischemic stroke and coronary artery disease (CAD) share common risk factors and pathophysiology, the risk of stroke in patients with CAD remains unclear. We sought to evaluate the risk of ischemic stroke in patients with suspected CAD according to coronary computed tomographic angiography (CCTA) and single-photon emission computed tomography (SPECT) findings. Presence, severity, and extent of CAD were evaluated in 1137 patients with suspected CAD who underwent CCTA and SPECT. Primary outcome was the occurrence of ischemic stroke. During follow-up (median 26 months), ischemic stroke was obse...

Assessment of Intracranial Collaterals on CT Angiography in Anterior Circulation Acute Ischemic Stroke FELLOWS' JOURNAL CLUB
CONCLUSIONS: Only the Miteff scoring system for intracranial collaterals is reliable for predicting favorable outcome in thrombolyzed acute anterior circulation ischemic stroke. However, poor outcomes can be predicted by most of the existing methods of scoring intracranial collaterals.

Predictors of response to endovascular treatment of posterior circulation stroke
ConclusionsPretreatment determination of the presence or absence of intracranial atherosclerosis can aid management of posterior circulation stroke patients. The absence of intracranial atherosclerosis may have value as a positive selection criterion for endovascular treatment in future trials. The presence of intracranial atherosclerosis could be used as a selection tool in future studies investigating new treatment protocols for this population.

Visualization of Lenticulostriate Arteries by Flow-Sensitive Black-Blood MR Angiography on a 1.5T MRI System: A Comparative Study between Subjects with and without Stroke BRAIN
CONCLUSIONS: Using FSBB-MRA to visualize LSA branches, we found a significant reduction in the numbers of LSA branches in patients with stroke, and hypertension was inversely related to total LSA length. FSBB is a promising method to investigate the LSA by using 1.5T MR imaging.

Micro‐vascular imaging experiences of time‐of‐flight MRA at 7T for cerebrovascular diseases
This study is to examine patients with vascular diseases using ultra‐high field 7T MRI with conventional time‐of‐flight (TOF) sequence, 3D fast low‐angle shot (FLASH) gradient‐echo. We have evaluated several radio‐frequency (RF) coils to find the optimal one for 7T magnetic resonance angiography (MRA), especially for micro‐vascular imaging. We have conducted several comparison studies with vascular disease patients. The results showed that micro‐vessels such as lenticulostriate arteries in the subjects with risk factors like hypertension or stroke patients were significantly less than in the healthy subject...

Predictors of Good Outcomes in Patients with Failed Endovascular Thrombectomy.
CONCLUSION: Baseline NIHSS score, good collateral status, and mTICI 2a recanalization remained independently associated with clinical outcome in non-recanalized patients. mTICI 2a recanalization would benefit patients with good collaterals in non-recanalized AC-LVO patients despite EVT.

Quantitative computed tomography of pulmonary emphysema and ventricular function in chronic obstructive pulmonary disease patients with pulmonary hypertension.
CONCLUSION: The study revealed that percent emphysema is correlated with RV dysfunction among COPD patients with PH. Based on our findings, percent emphysema can be considered for use as an indicator to predict the severity of right ventricular dysfunction among COPD patients. PMID: 25469102 [PubMed - in process]

Successful endovascular recanalization of a partially occluded basilar artery fenestration.
Authors: Meinel TR, Pult F, Gralla J, Arnold M, Bassetti C, Jung S Abstract A 76-year-old man with a history of arterial hypertension, obstructive sleep apnea, dyslipidemia, family history of cardiovascular events, prestroke and overweight presented 90 minutes after acute onset of right-sided sensorimotor hemiparesis, hemiataxia and dysarthria (National Institutes of Health Stroke Scale (NIHSS) 9/42). Magnetic resonance imaging (MRI) revealed a pontine ischemia and MR angiography showed a thrombus in the middle to distal portion of the basilar artery. Owing to the location, an occlusion of one lumen of a fenestrate...

A Pictorial Review of Intracranial Haemorrhage Revisited.
CONCLUSION: Unenhanced CT is a mainstay of acute phase imaging due to its availability and, sensitivity and specificity for detecting acute haemorrhage. Several imaging features can be identified on CT and, along with clinical information, can provide some certainty in diagnosis. For those suitable and where diagnostic uncertainty remains CT angiogram, time-resolved CT angiography and catheter angiography can help identify underlying AVMs, aneurysms, cavernomas and vasculitides. MRI is more sensitive for the detection of subacute and chronic haemorrhage and identification of underlying mass lesions. PMID: 32008532 [PubMed - in process]

Uncontrolled hypertension associates with subclinical cerebrovascular health globally: a multimodal imaging study
ConclusionsUncontrolled hypertension was associated with subclinical cerebrovascular injury globally, with both small and medium-to-large arteries being affected.Key Points• In this study, we leveraged the advantage of a series of cutting-edge MR imaging and analysis techniques and found uncontrolled hypertension is associated with subclinical globally compromised cerebrovascular health.• The detrimental consequences of uncontrolled BP affect not only the small vessels but also the medium-to-large arteries, and uncontrolled systolic and diastolic BP are both independently associated with certain types of cerebrovascula...
