Diagnosing intra-cranial and cervical artery dissection using MRI as the initial modality

Area of Science:

• Neurology
• Radiology
• Vascular Medicine

Background:

• Cranial and cervical artery dissections are common but challenging to diagnose, especially with subtle symptoms.
• Accurate diagnosis is vital for timely and effective treatment to prevent complications.

Purpose of the Study:

• To evaluate the effectiveness of the "MR first concept" in diagnosing cranial and cervical artery dissections.
• To analyze the characteristics of dissections in relation to clinical presentation and affected arteries.

Main Methods:

• Retrospective analysis of 164 patients admitted between January 2001 and December 2014.
• Utilized Magnetic Resonance Imaging (MRI) as the primary diagnostic modality for all new neurological symptom patients.
• Categorized patients into carotid and vertebral dissection groups for statistical comparison.

Main Results:

• Vertebral artery dissections (73.2%) were more frequent than carotid artery dissections (26.8%).
• Statistically significant differences were observed between carotid and vertebral groups regarding hemiparesis, aphasia, trauma history, headache, and vertigo.
• Headache or neck pain as the sole symptom was more prevalent than previously reported.

Conclusions:

• The "MR first concept" facilitates early detection of cranial and cervical artery dissections.
• Prompt diagnosis through MRI enables timely initiation of treatment, potentially improving patient outcomes.
