Summary
Mobile stroke units with CT angiography rapidly detect large vessel occlusions, enabling faster patient triage to stroke centers for quicker treatment and improved outcomes.
Area of Science:
- Neurology
- Emergency Medicine
- Radiology
Background:
- Acute ischemic stroke outcomes correlate inversely with reperfusion time.
- Delays in transferring patients to specialized centers limit treatment effectiveness.
- Mobile Stroke Units (MSUs) equipped with CT scanners can expedite diagnosis and triage.
Observation:
- A Mobile Stroke Treatment Unit (MSTU) with CT angiography (CTA) capability was implemented.
- The first field-performed CTA in the US was conducted on an MSTU for emergent large vessel occlusion (ELVO) triage.
- A patient presenting with stroke symptoms underwent rapid assessment and CTA on the MSTU.
Findings:
- CTA on the MSTU identified a left middle cerebral artery (MCA) occlusion.
- The patient was immediately transferred to a neurointerventional center.
- Successful recanalization and symptom improvement were achieved post-treatment.
Implications:
- Field-performed CTA on MSUs enables rapid detection and triage of ELVO patients.
- This approach significantly reduces the time to endovascular treatment.
- Mobile stroke units enhance the efficiency of acute stroke care and improve patient outcomes.

529
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
