Performance of multi-contrast MRI plaque imaging has been validated by histology.
Saam T, et al. ATVB. 2005
Cardiovascular and cerebrovascular diseases have been the No.1 killer in the world for decades according to the report from The World Health Organization. It is now an urgent issue on how to effectively treat stroke victims worldwide. Atherosclerotic plaques are closely related to ischemic stroke. Rupture of vulnerable plaques causing thrombosis can lead to ischemia and necrosis of brain.
In order to prevent and control a stroke, it is important to identify and treat plaques at an early stage.
In a conventional diagnosis of carotid plaques, ultrasound, CT or DSA were used to measure the severity of stenosis. However, many studies have shown that the degree of stenosis frequently underestimates plaque severity, causing patients to miss the best treatment opportunity. Plaque vulnerability associated with plaque components, which has been supported by histology, would be a strong predictor for an ischemic stroke.
The best solution of evaluating plaque vulnerability would be high-resolution MR vessel wall imaging. We have developed this technology to delineate the vessel wall structure and visualize plaque components more clearly.

Introduction
Multi-contrast joint intra and extra-cranial
MR sequences
Well-trained specialists, image interpretation software, precise and accurate reports, within 24 hours
Introduction of PLAQUECARE
Custom-designed 8 channel carotid coil
PLAQUECARE solution, developed by TSimaging Healthcare collaborated with CBIR, contains the following products:
• Custom-designed vascular coils
• Standardized black-blood vessel wall MR imaging protocols
• Plaque image processing workstation
PLAQUECARE meets the VesselAIDTM standard and ensures its application by providing professional training for our customers.
Multi-contrast carotid plaque MR sequences
Multi-contrast carotid plaque MR sequences provide TOF, Hyper T1-w, T1-w and T2-w images to qualitatively and quantitatively assess carotid morphology and plaque components.
In addition, we also have developed 3D large-coverage multi-contrast MR sequences, covering a field of view from common carotid arteries to internal carotid arteries and vertebral arteries.

CASE II
Male, 58 years old, sudden numbness and weakness in left limb, headaches for 6 hours.
Diabetes for 10 years, hypertension for 10 years.
DSA:
Right ICA occlusion; atherosclerosis in left intracranial and carotid arteries.
MRI:
acute cerebral infarction in right corona radiate.right internal carotid artery: invisible;vulnerable plaque (red arrows) and thrombus (red triangles) in right ICA.
Comment: MR plaque imaging is the best way to diagnose the ischemic stroke by precisely identifying vulnerable plaques in intra-and extra-cranial arteries.
Comment: Plaque composition, rather than stenosis, is the best indicator of plaque vulnerability. MR vessel wall imaging is the first choice to evaluate vulnerable plaque by directly revealing the pathological characteristics of plaque.
CASE V
CASE VI
CASE IV
Female, 31 years old, intermittent insomnia for 4 years and gradually aggravate more than 20 days with headaches.
MRI:
One-stop carotid artery wall imaging clearly and comprehensively shows the large-scale annular thickening of the left and right common carotid arteries, with the left side as the weight, resulting in obvious stenosis of the lumen, which is consistent with changes in arterial vasculitis.
Male, 50 years old, weakness in right limb for 3 days
MRI:
Acute cerebral infarction in left corona radiate; no stenosis in bilateral ICA; occlusion in M1 segment of left MCA. MR plaque imaging shows atherosclerotic plaque formation in M1 segment of left MCA.
Comment: MR plaque imaging can not only visualize extra-cranial, but also intra-cranial atherosclerotic plaques.
Male, 73 years old, intermittent dizzy for one year,syncope occurs twice.
MRI:
vulnerable plaque in right carotid artery; clinical symptoms disappear after CEA.
Figure A: no cerebrovascular stenosis on TOF-MRA
Figure B: Plaque in left carotid artery
Figure C: Plaque in right carotid artery (before CEA)
Figure D: Plaque in right carotid artery (after CEA)
Male, 79 years old, sudden numbness in left limb, dyskinesia, dizziness for 8 days
MRI:
IPH (red arrows) in right ICA and mixed plaque (red triangles) in left carotid artery;
Acute cerebral infarction in right basal ganglia in DWI and T2-FLAIR.By combining this information, we can confirm that plaque with IPH in right ICA is the culprit plaque.
Male, 56 years old, sudden numbness in right limb, aphasia for 4 days, TIA for 2-3 years
MRI:
Dissection in left ICA, including true and false lumen, intimal flap and inflammatory infiltration, can be clearly visualized in curved multi-planar reconstruction images.
