Computed Tomography

6.4K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...

Summary

Prompt diagnosis and rapid imaging are crucial for effective acute ischemic stroke (AIS) treatment in children. Computed tomography angiography (CTA) aids in timely interventions for large vessel occlusions, improving outcomes.

Area of Science:

  • Pediatric Neurology
  • Vascular Neurology
  • Emergency Medicine

Background:

  • Acute ischemic stroke (AIS) in children requires timely diagnosis and treatment.
  • Clinical presentation of pediatric AIS can vary, influencing diagnostic speed.
  • Effective delivery of acute therapies is essential to improve outcomes.

Purpose of the Study:

  • To identify factors influencing the speed of diagnosis and delivery of acute therapies for pediatric AIS.
  • To evaluate the role of imaging modalities in facilitating rapid treatment.

Main Methods:

  • Prospective cohort study of children with suspected AIS.
  • Retrospective analysis of children with confirmed AIS.
  • Analysis of clinical features, imaging (CTA, MRA), and treatment interventions.

Main Results:

  • Children presenting with symptoms other than sustained hemiparesis had slower diagnosis.
  • Computed tomography angiography (CTA) facilitated quicker diagnosis and treatment compared to MRI/MRA.
  • Arterial abnormalities were identified in 31/51 AIS patients, including large vessel occlusion, dissection, and moyamoya disease.
  • 80% of AIS patients without arterial abnormalities were ineligible for thrombolysis, but showed good outcomes with supportive care.

Conclusions:

  • Clinical presentation significantly impacts the recognition and diagnosis of AIS in children.
  • CTA is effective in identifying large vessel occlusions and guiding thrombectomy and thrombolysis.
  • Most childhood AIS without identifiable arterial abnormalities have favorable outcomes with supportive care.
