Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

174
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

85
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

73
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

110
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...

X-ray Imaging01:24

X-ray Imaging

5.2K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Computed Tomography01:10

Computed Tomography

4.1K
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...

Summary
This summary is machine-generated.

Federally qualified health centers (FQHCs) partnerships increase geographic imaging access for underserved populations. This study found that FQHC patients were younger, more diverse, and had higher social deprivation scores, indicating improved access.

Area of Science:

  • Radiology and Medical Imaging
  • Public Health
  • Health Equity

Background:

  • Federally qualified health centers (FQHCs) are crucial for serving medically underserved populations.
  • UW Health partnered with Access Community Health Centers (ACHC) in 2013 to offer on-site outpatient imaging.
  • Understanding radiography utilization in FQHCs is vital for improving healthcare access.

Purpose of the Study:

  • To characterize radiography utilization at UW Health's FQHC partner (ACHC) compared to other UW Health outpatient imaging sites.
  • To identify patient demographics and factors associated with imaging use at ACHC.

Main Methods:

  • Analysis of outpatient radiography data from January 2013 to December 2022.
  • Comparison of patient characteristics between ACHC and non-ACHC UW Health clinic users using statistical tests.
  • Logistic regression to determine factors influencing ACHC radiography service utilization.

Main Results:

  • 4% of total imaging encounters and 4% of patients utilized ACHC facilities.
  • ACHC patients were younger, more often female, Black, Hispanic, had Medicaid or were uninsured, and lived in metropolitan areas with higher social deprivation.
  • Minority patients, those without commercial insurance, and non-English speakers were more likely to use ACHC radiography services.

Conclusions:

  • FQHCs are trusted community centers that enhance access for underserved groups.
  • Partnerships between academic health systems and FQHCs can significantly improve geographic access to essential imaging services for vulnerable populations.
