Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

465
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

556
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies for Cardiovascular System III: X-Ray

559
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

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...

Area of Science:

  • Forensic Pathology
  • Radiology
  • Medical Imaging

Background:

  • Multi-phase post-mortem computed tomography angiography (MPMCTA) enhances visualization of lesions.
  • The invasiveness of conventional MPMCTA, requiring surgical cannulas, often leads to family refusal of scientific autopsies.

Purpose of the Study:

  • To evaluate the feasibility of a minimally-invasive MPMCTA approach using radiological catheters.
  • To compare the performance of the minimally-invasive MPMCTA with the conventional surgical cannula method.
  • To assess if this minimally-invasive technique improves autopsy approval rates.

Main Methods:

  • A comparative study involving 16 corpses, divided into two groups (n=8 each).
  • Group 1: Minimally-invasive MPMCTA using radiological catheters.
  • Group 2: Conventional MPMCTA using surgical cannulas.
  • Evaluation of vascular opacification quality (global, cerebral venous, lower limb arterial/venous).

Main Results:

  • The minimally-invasive MPMCTA approach using radiological catheters is feasible for scientific autopsies.
  • Optimal vascular opacification was achieved in all 8 cases using the radiological catheter method.
  • The effectiveness of vascular opacification was comparable to the conventional surgical cannula approach.

Conclusions:

  • Minimally-invasive MPMCTA with radiological catheters is a viable alternative to the conventional surgical method.
  • This technique demonstrates optimal vascular opacification, suggesting potential for increased acceptance of scientific autopsies.
  • Further studies may confirm improved autopsy approval rates with this less invasive procedure.
