Brief Summary

Among patients admitted with cerebral ischemia (stroke and transitory ischemic attack (TIA)) it is important to reveal the underlying cause of the disease. In special it is important to reveal if carotid artery stenosis is present as such a finding will directly influence on treatment and follow-up. For the diagnosis of carotid artery stenosis due to atherosclerosis ultrasound examinations is the cornerstone, but computer tomography and magnetic resonance imaging may be better in some cases. Development of high quality pocket-sized ultrasound scanners has allowed for semi quantitatively bed-side assessment of the carotid arteries and the heart. The investigators aim to study the feasibility and reliability of bed-side assessment of the carotid arteries and the heart by pocket-sized ultrasound scanners and the clinical influence of this examination when performed by experienced users. The investigators hypothesize that a significant proportion of this patient population can be clarified bed-side with no need of further imaging procedures for the assessment of the carotid arteries and the heart.

Outcome Measures

Primary Outcomes (1)

• Proportion of patients without need for further diagnostic imaging

  Proportion of patients which is not in need of further imaging procedures of the carotid arteries and the heart after bed-side diagnostic ultrasound by pocket-sized scanner

  The participants will be followed for the duration of hospital stay, an expected average of approximately 4 days

Secondary Outcomes (2)

• Reliability of bed-side ultrasound examinations of the carotid arteries and the heart by pocket-sized scanners

  The participants will be followed for the duration of hospital stay, an expected average of approximately 4 days

• Feasibility of bed-side ultrasound examinations of the carotid arteries and the heart by pocket-sized scanners

  The participants will be followed for the duration of hospital stay, an expected average of approximately 4 days

Other Outcomes (1)

• Clinical influence of bed-side ultrasound examinations of the carotid arteries and the heart in patients admitted with symptoms of stroke

  The participants will be followed for the duration of hospital stay, an expected average of approximately 4 days

Study Arms (1)

Bed-side pocket-size ultrasound

EXPERIMENTAL

All participants will be examined bed-side by pocket size ultrasound for the assessment of the carotid arteries and the heart. All participants will then be examined by reference imaging in specific ultrasound laboratories and when appropriate computer tomography or magnetic resonance imaging.

Procedure: Bed-side pocket size ultrasound imaging; Device: GE Ultrasound Vscan
