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

Imaging Studies for Cardiovascular System III: X-Ray

600
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 VII: Vascular Imaging

448
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...

Imaging Studies for Cardiovascular System V: CT

502
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

611
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...

Cardiac Catheterization I: Pre-Procedure Overview

2.2K
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

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:

  • Healthcare Operations Research
  • Medical Imaging Workflow Analysis

Background:

  • Efficient patient flow is critical for healthcare delivery.
  • Interventional Radiology (IR) procedures require complex preprocedural coordination.
  • Delays in preprocedural patient flow can impact resource utilization and patient care.

Purpose of the Study:

  • To quantify preprocedural patient flow in Interventional Radiology (IR).
  • To identify key factors contributing to preprocedural delays in IR.
  • To highlight areas for potential workflow optimization.

Main Methods:

  • Analysis of an administrative dataset for preprocedural time intervals.
  • Comparison of time intervals between on-time/delayed and inpatient/outpatient cases.
  • Statistical analysis including Mann-Whitney U test, Spearman correlation, and multivariate linear regression.

Main Results:

  • 65.8% of 1,091 IR cases experienced preprocedural delays.
  • Outpatient cases had significantly higher delay rates (81.4%) compared to inpatient cases (45.0%).
  • Factors associated with longer preprocedural times included outpatient status, delayed patient arrival, and longer procedure durations. Common delay reasons were late patient arrival (65.9%), physician unavailability (18.4%), and procedure room unavailability (13.0%).

Conclusions:

  • Objective measurement of preprocedural IR patient flow reveals significant inefficiencies.
  • Identifying specific delay contributors offers high-yield opportunities for process improvement.
  • A data-driven approach can enhance the efficiency of IR care delivery.
