Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

393
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...

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...

Imaging Studies VII: Vascular Imaging

171
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...

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...

Imaging Studies for Cardiovascular System IV: CMRI

236
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Area of Science:

  • Radiology
  • Public Health
  • Epidemiology

Background:

  • The COVID-19 pandemic significantly impacted healthcare delivery.
  • Understanding changes in diagnostic imaging utilization is crucial for resource allocation and patient care.

Purpose of the Study:

  • To analyze emergency department (ED) imaging utilization trends during the COVID-19 pandemic.
  • To assess the impact of the pandemic on imaging volumes across different modalities and body parts within a multicenter health system.

Main Methods:

  • A retrospective observational study analyzed ED imaging volumes from March 1, 2020, to May 11, 2020.
  • Rolling 7-day totals tracked imaging utilization, comparing it with regional COVID-19 case counts.
  • Statistical analysis assessed changes in modality-specific and body part-specific imaging volumes, including computed tomography (CT) chest and CT chest, abdomen, and pelvis (C/A/P) exams.

Main Results:

  • Overall ED imaging utilization decreased by 46% (p < 0.0001).
  • Statistically significant decreases were observed across most modalities and body parts.
  • Non-contrast chest CT utilization increased (p = 0.0053), while non-trauma C/A/P CT showed no significant change (p = 0.0633).

Conclusions:

  • The COVID-19 pandemic led to substantial shifts in ED imaging utilization patterns.
  • These data provide insights for evidence-based volume predictions and enhanced institutional preparedness for future public health crises.
  • Understanding imaging trends is vital for optimizing healthcare system response during pandemics.
