“…However, advances in hardware and the development of novel imaging techniques have decreased acquisition times and thus MR-based protocols for acute imaging of stroke are becoming more commonly used. 41 Time-of-flight MR angiography (TOF-MRA) is a T1-based sequence that does not require gadolinium injection and is used to assess the proximal intracranial vasculature. It is based on blood flow which generates a visible signal.…”

The collateral circulation plays a crucial role in maintaining perfusion to brain tissue in ischemic stroke, which prolongs the time window for effective therapies to be provided and ultimately avoids irreversible damage that may lead to worse clinical outcomes. The understanding of this complex vascular bypass system has advanced greatly in the past few years, yet effective treatments for its potentiation as a therapeutic target remain a challenge. The assessment of the collateral circulation is now part of the routine neuroimaging protocols for acute ischemic stroke, which provides a more complete pathophysiological picture in each patient that allows for a better selection for acute reperfusion therapies and a more accurate prognostication of outcomes, among other potential uses. In this review, we aim to provide a structured and updated approach to the collateral circulation while highlighting ongoing research areas with promising future clinical applications.

“…It may present as reduced gray-white matter differentiation. While this sign is present in up to 60% of ischemic stroke cases [9], its identification can be challenging, with sensitivities for recognizing MCA territory hypodensity ranging between 60% and 85% [19].…”

“…Still, CT is more extensively used, can promptly exclude acute cerebral hemorrhages and is more favorable speed-wise [8]. CT perfusion (CTP) imaging benefits the selection of AIS patients for EVT by facilitating core infarct volume calculations, necessitating less workflow in deducting the onset time of strokes that arise in patients that have no previous symptoms before waking up [9]. Aging ISs can be important in both clinical and medico-legal circumstances, and more accurate information can be provided through MRI.…”

Strokes are one of the global leading causes of physical or mental impairment and fatality, classified into hemorrhagic and ischemic strokes. Ischemic strokes happen when a thrombus blocks or plugs an artery and interrupts or reduces blood supply to the brain tissue. Deciding on the imaging modality which will be used for stroke detection depends on the expertise and availability of staff and the infrastructure of hospitals. Magnetic resonance imaging provides valuable information, and its sensitivity for smaller infarcts is greater, while computed tomography is more extensively used, since it can promptly exclude acute cerebral hemorrhages and is more favorable speed-wise. The aim of this article was to give information about the neuroimaging modalities used for the diagnosis and monitoring of ischemic strokes. We reviewed the available literature and presented the use of computed tomography, CT angiography, CT perfusion, magnetic resonance imaging, MR angiography and MR perfusion for the detection of ischemic strokes and their monitoring in different phases of stroke development.

“…Diagnozuojant išeminį insultą, vertinama parenchima, kraujagyslės, perfuzija, penumbra [7]. Dažniausiai naudojamos šios sekos: DWI/ ADC, T2, T2_FLAIR bei MR angiografija ir MR perfuzijos tyrimai [8]. Išeminis insultas skirstomas pagal įvykimo laikotarpius.…”

Pagrindinis išeminio insulto diagnostikos metodas yra kompiuterinė tomografija (KT). Tobulėjant tyrimo metodams, vis dažniau praktikoje naudojamas magnetinio rezonanso tomografijos (MRT) tyrimas, kuris padeda nustatyti tikslesnį išemijos laiką ir parinkti tinkamiausią gydymo taktiką. Tyrimo tikslas − išanalizuoti ir apžvelgti įrodymais grįstoje mokslinėje literatūroje išeminio insulto diagnostiką MRT tyrimu.
