“…CAROTID ARTERY DISEASE has been investigated using many different MR techniques including time-offlight MR angiography (TOF MRA), contrast-enhanced MRA, and black blood fast spin echo (BB FSE) techniques (1)(2)(3)(4)(5)(6). Although contrast-enhanced techniques are extremely robust for vessel lumen imaging, the noncontrast approaches are also valuable.…”

Purpose: To evaluate steady-state free precession (SSFP) for diagnosing carotid artery disease. Materials and Methods:Following bilateral x-ray angiography, seven patients with suspected carotid artery disease were imaged with SSFP, black blood fast spin echo (BB FSE), and time-of-flight MR angiography (TOF MRA). The techniques were compared for characterizing the vessel lumen. Flow phantom experiments were also performed, using speeds of 0 to 40 cm/second, to further evaluate the merits of each MR technique.

“…However, one of the well-known limitations of TOF-MRA is that signal saturation and dephasing of the signal could lead to a signal loss from focal areas of complex flow. 60 The stenosis measurement accuracy of TOF is dependent on the wash-in efficiency of unsaturated spins within the imaging section/slab. For large ulcerations, the hemodynamic patterns of blood flow are complicated.…”

SUMMARY: Atherosclerosis remains the leading cause of long-term mortality and morbidity worldwide, despite remarkable advancement in its management. Vulnerable atherosclerotic plaques are principally responsible for thromboembolic events in various arterial territories such as carotid, coronary, and lower limb vessels. Carotid plaque ulceration is one of the key features associated with plaque vulnerability and is considered a notable indicator of previous plaque rupture and possible future cerebrovascular events. Multiple imaging modalities have been used to assess the degree of carotid plaque ulceration for diagnostic and research purposes. Early diagnosis and management of carotid artery disease could prevent further cerebrovascular events. In this review, we highlight the merits and limitations of various imaging techniques for identifying plaque ulceration.ABBREVIATIONS: CE-MRA ϭ contrast-enhanced MRA; CDUS ϭ color Doppler ultrasound; CEUS ϭ contrast-enhanced ultrasound; US ϭ ultrasound; XRA ϭ x-ray

“…In due course, it was realised that these apparently errant signals could be exploited to generate diagnostic quality images of blood vessels. For example, phase contrast velocity MRI [175] estimates the phase shift of hydrogen nuclei as they pass through a magnetic field and this phase change is proportional to velocity [176]. Other methods of time-resolved contrast-enhanced functional assessment have since been introduced, for example, time-of-flight MR angiography (TOF MRA) [177] and contrast-enhanced MR-angiography (CEMRA) [178].…”

Physics has delivered extraordinary developments in almost every facet of modern life. From the humble thermometer and stethoscope to X‐Ray, CT, MRI, ultrasound, PET and radiotherapy, our health has been transformed by these advances yielding both morphological and functional metrics. Recently high resolution label‐free imaging of the microcirculation at clinically relevant depths has become available in the research domain. In this paper, we present a comprehensive review on current imaging techniques, state‐of‐the‐art advancements and applications, and general perspectives on the prospects for these modalities in the clinical realm.
