Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

167
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...

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

245
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Computed Tomography

7.7K
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...

Area of Science:

  • Cardiovascular Imaging
  • Thoracic Surgery
  • Radiology

Background:

  • Prosthetic aortic graft repair is crucial for conditions like aortic aneurysms and dissections.
  • Understanding post-surgical imaging is vital for diagnosing complications accurately.
  • Familiarity with graft materials and normal imaging is necessary for interpretation.

Purpose of the Study:

  • To review the normal multidetector computed tomography (MDCT) appearance of prosthetic ascending aortic grafts.
  • To detail the imaging evaluation of potential post-surgical complications following aortic graft repair.
  • To differentiate true complications from imaging mimics after ascending aorta and aortic valve repair.

Main Methods:

  • Review of multidetector computed tomography (MDCT) imaging protocols.
  • Analysis of expected benign postoperative changes.
  • Identification and characterization of various prosthetic aortic graft complications.

Main Results:

  • MDCT provides accurate assessment of prosthetic aortic grafts.
  • Common complications include graft-related issues and secondary involvement of adjacent structures.
  • Distinguishing normal postoperative changes from true complications is achievable with MDCT.

Conclusions:

  • MDCT is the optimal imaging modality for evaluating prosthetic ascending aortic grafts.
  • Knowledge of normal and abnormal imaging findings is essential for patient management.
  • This review aids radiologists and surgeons in diagnosing complications after aortic graft repair.
