Computed Tomography01:10

Computed Tomography

9.1K
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...

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...

Seizures: Classification01:13

Seizures: Classification

1.8K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Summary

Computed tomography (CT) scans revealed abnormalities in 66% of partial seizure patients. Tuberculomas were the most common finding, even in patients without clear clinical signs or normal electroencephalograms (EEGs).

Area of Science:

  • Neurology
  • Radiology
  • Infectious Diseases

Background:

  • Partial seizures are a common neurological disorder.
  • Accurate diagnosis is crucial for effective treatment.
  • Computed tomography (CT) is a key imaging modality in epilepsy evaluation.

Purpose of the Study:

  • To assess the diagnostic utility of CT scans in patients with partial seizures.
  • To identify common CT abnormalities associated with partial seizures.
  • To evaluate the role of CT in detecting treatable causes of seizures.

Main Methods:

  • A prospective study of 50 consecutive partial seizure patients.
  • CT scans performed at presentation and for follow-up where indicated.
  • Correlation of CT findings with clinical signs and electroencephalography (EEG).

Main Results:

  • CT scan abnormalities were detected in 66% of patients.
  • Tuberculomas were identified in 24% of cases, a significant finding.
  • Abnormal CT findings were more frequent in patients with positive clinical signs (81%).
  • Notably, 20% of patients with normal clinical signs and EEG showed CT abnormalities, primarily tuberculomas.

Conclusions:

  • CT scanning is a valuable tool for diagnosing partial seizures, detecting structural abnormalities.
  • Tuberculomas represent a significant, treatable cause of partial seizures, even with subtle or absent clinical indicators.
  • Routine CT evaluation can aid in identifying underlying pathologies and guiding treatment strategies for partial seizures.
