Computed Tomography01:10

Computed Tomography

9.0K
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...

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...

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...

Area of Science:

  • Gastroenterology
  • Radiology
  • Surgical Oncology

Background:

  • Adhesive small bowel obstruction (ASBO) is a common surgical emergency.
  • Complications include bowel volvulus, ischemia, and necrosis, significantly impacting patient prognosis.
  • Timely diagnosis and intervention are critical for preserving bowel viability.

Observation:

  • Physical examination alone is often insufficient for diagnosing ASBO and its complications.
  • Computed tomography (CT) is the preferred imaging modality for evaluating suspected ASBO.
  • The 'whirl sign' on CT is a key indicator of bowel volvulus.

Findings:

  • The whirl sign on computed tomography is highly suggestive of small bowel volvulus.
  • The presence of the whirl sign can be sufficient evidence to warrant surgical exploration.
  • Early detection of volvulus via CT imaging improves the chances of successful management.

Implications:

  • Prompt surgical intervention based on CT findings, particularly the whirl sign, can prevent bowel necrosis.
  • Accurate and rapid diagnosis improves patient outcomes and reduces morbidity associated with ASBO.
  • CT imaging, with emphasis on the whirl sign, plays a vital role in the management of adhesive small bowel obstruction.
