Computed Tomography01:10

Computed Tomography

4.7K
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...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

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...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Summary
This summary is machine-generated.

Surgeons should suspect aortic dissection in patients with chest pain and ascending aortic aneurysm, even with negative initial imaging. Early operation is crucial despite atypical computed tomography angiography findings.

Area of Science:

  • Cardiovascular Surgery
  • Diagnostic Imaging
  • Thoracic Aortic Disease

Background:

  • Computed tomography angiography (CTA) is standard for diagnosing type A aortic dissection.
  • False negative/positive CTA results for dissection are rare.
  • Ascending aortic aneurysms with chest pain warrant surgical consideration, even with negative imaging.

Purpose of the Study:

  • To highlight the importance of surgical suspicion for type A aortic dissection.
  • To present cases where diagnosis was confirmed intraoperatively despite initial negative CTA.
  • To emphasize the need for vigilance in patients with chest pain and ascending aortic aneurysms.

Main Methods:

  • Retrospective case series of 4 patients (2004-2021) presenting with chest pain.
  • All patients had ascending aortic aneurysms without a dissection flap on CTA.
  • Echocardiography revealed moderate-severe aortic regurgitation in 2, pericardial effusion in 2.

Main Results:

  • Diagnosis of type A aortic dissection was confirmed during surgery in all 4 patients.
  • All patients had favorable outcomes postoperatively.
  • One patient experienced a complication (compartment syndrome) requiring amputation due to coagulopathy.

Conclusions:

  • Maintain high suspicion for aortic dissection in patients with chest pain and ascending aortic aneurysm, irrespective of initial CTA findings.
  • Surgical intervention is indicated even with non-classic imaging features.
  • Further advancements in imaging techniques and analysis are necessary for improved diagnostic accuracy.
