Summary
A new method reliably assesses cervical artery tortuosity from MRA images, offering a simpler approach for diagnosing connective tissue disorders and studying spontaneous cervical artery dissection (sCeAD). This technique shows higher accuracy than visual appraisal.
Area of Science:
- Radiology
- Vascular Imaging
- Connective Tissue Disorders
Background:
- Assessing subclinical connective tissue disorders often requires complex methods.
- There is a need for more accessible clinical routine approaches.
- Cervical vessel tortuosity is linked to connective tissue disorders.
Purpose of the Study:
- To develop a reliable method for assessing cervical artery tortuosity.
- To create an approach applicable to clinical routine.
- To investigate the association between cervical artery tortuosity and spontaneous cervical artery dissection (sCeAD).
Main Methods:
- Utilized magnetic resonance angiography (MRA) images from the ReSect study cohort.
- Employed MATrix LABoratory, ITK-SNAP, and Vascular Modelling ToolKit for image segmentation and analysis.
- Assessed inter-user variability and compared results against expert neuro-radiologist visual appraisal.
Main Results:
- Analyzed 526 extracranial cervical arteries.
- Achieved inter-user variability below 0.5%.
- The developed method demonstrated superior accuracy compared to visual tortuosity appraisal, which underestimated the distance metric in a significant percentage of cases.
Conclusions:
- A reliable MRA-based method for assessing cervical artery tortuosity is presented.
- The method is suitable for clinical routine and research.
- It can aid future investigations into the correlation between sCeAD and connective tissue disorders.

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
