“…These results indicate that chronic middle artery stenoses do not represent a significant source of emboli [11]. Transcranial Doppler sonography also allows for the monitoring of intracranial blood vessels in patients who had undergone thrombolysis [12] and also for the emergency diagnosis of ischemic stroke following head trauma [13].…”

In the study of carotid arteries, the different imaging techniques allow to analyze various diseases like stenoses, aneurysms, thromboses, dissections, diseases caused by atherosclerotic plaques or congenital abnormalities. The diagnostic modalities that are used to image the carotid artery diseases are digital subtraction angiography (DSA), duplex ultrasound (DUS), computed tomography angiography (CTA), and magnetic resonance angiography (MRA). The goal of the diagnostic imaging is to provide screening and to detect diseases at its earliest and most treatable stage. As initial screening study, the radiologists recommend DUS. It is a safe and painless way to produce pictures of the inside of the body using sound waves. It assesses blood flow in the carotid arteries, measures the speed of the blood flow, and estimates the diameter of a blood vessel and degree of obstruction. Digital subtraction angiography (DSA) has assumed a major role in the evaluation of occlusive cerebrovascular disease. While digital subtraction angiography (DSA) is still considered the gold standard, it has increasingly been replaced by computed tomography angiography (CTA) or magnetic resonance angiography (MRA) during the last years. Modern imaging studies like CTA and MRI allow to obtain three-dimensional reconstruction of anatomic structures and pathological abnormalities. Computed tomography angiography (CTA) of carotid arteries is a standardized procedure with excellent image quality but related with high radiation exposure. The rapid technical evolution in hardware and software allows even smaller imaging centers to perform high-quality vessel imaging. During the last decade, CTA came up with substantial progress in terms of accuracy in stenosis and aneurysm detection. Magnetic resonance angiography (MRA) is increasingly used as a noninvasive method to assess carotid arteries. Diseases like carotid artery dissections could be detected by using MRA or CTA.

“…It is noteworthy that the blood flow (dots) in ROI 3 presents a periodic behavior (~1 Hz) which is appreciated due to the high acquisition rate of the system. This phenomenon suggests a low perfusion state caused by the damaged capillaries in the infarct region, where the restoration of normal flow was disturbed, resulting in pulsatile increases in blood flow [19]. Overall, the hemodynamic and metabolic alternations in the occlusion followed by reperfusion in the whole mouse brain can be recorded by the instrument, with high spatiotemporal resolution, high sensitivity and with a large field of view.…”

Fast synchronized dual-wavelength laser speckle imaging system for monitoring hemodynamic changes in a stroke mouse model

et al. 2012

View full text Add to dashboard Cite

In this paper, we describe a newly developed synchronized dual-wavelength laser speckle contrast imaging (SDW-LSCI) system, which contains two cameras that are synchronously triggered to acquire data. The system can acquire data at a high spatiotemporal resolution (up to 500Hz for ~1000×1000 pixels). A mouse model of stroke is used to demonstrate the capability for imaging the fast changes (within tens of milliseconds) in oxygenated and deoxygenated hemoglobin concentration, and the relative changes in blood flow in the mouse brain, through an intact cranium. This novel imaging technology will enable the study of fast hemodynamics and metabolic changes in vascular diseases.
