Computed Tomography

Computed Tomography

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...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Imaging Studies for Cardiovascular System V: CT

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...

Computerized transverse axial tomography in the newborn.

M L Chiswick, S W D'Souza, J V Occleshaw

Early Human Development

|October 1, 1977

Summary

Computerized transverse axial tomography identified structural brain lesions in 6 of 7 infants with abnormal neurological signs. These findings highlight the utility of this imaging technique in early neonatal neurological assessment.

Area of Science:

Neonatal neurology
Pediatric neuroimaging
Diagnostic radiology

Background:

Early identification of neurological abnormalities in newborns is crucial for timely intervention.
Computerized transverse axial tomography (CTAT) is a valuable tool for evaluating structural brain abnormalities in infants.
Abnormal neurological signs in the neonatal period warrant thorough investigation to determine underlying causes.

Observation:

Seven infants, aged 6 days to 8 weeks, presenting with abnormal neurological signs were evaluated.
Three of the infants had a history of perinatal asphyxia.
General anesthesia was required in only one infant for the CTAT procedure.

Findings:

Structural intracranial lesions were detected in 6 out of the 7 infants studied.

The identified lesions included hydranencephaly, cerebral agenesis with dilated lateral ventricles, unilateral cerebral edema, and subarachnoid cysts.

Localized cerebral atrophy was also observed in some cases.

Implications:

CTAT effectively visualizes significant structural intracranial pathologies in neonates with neurological deficits.
The study underscores the importance of neuroimaging in diagnosing diverse brain abnormalities in the early neonatal period.
These findings can guide further management and prognostic assessments for affected infants.
