Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

1.4K
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...

Imaging Studies for Cardiovascular System III: X-Ray

550
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...

Computed Tomography

9.2K
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...

X-ray Imaging

10.8K
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

636
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Imaging Studies for Cardiovascular System V: CT

460
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...

Summary

Computer-aided detection (CAD) for chest X-rays (CXRs) shows comparable performance to experienced radiologists in diagnosing pulmonary tuberculosis (TB) in low-resource settings. This technology aids physicians where radiologists are scarce, even with mobile phone images.

Area of Science:

  • Medical Imaging
  • Artificial Intelligence in Healthcare
  • Infectious Disease Diagnostics

Background:

  • Low-resource settings face challenges in tuberculosis (TB) diagnosis due to radiologist scarcity.
  • Chest X-rays (CXRs) are crucial for TB screening, but interpretation requires expertise.
  • Mobile radiography offers potential for wider reach but requires robust interpretation tools.

Purpose of the Study:

  • To evaluate the efficacy of computer-aided detection (CAD) CXR software in identifying pulmonary TB (PTB) in resource-limited, high-TB endemic areas.
  • To compare the diagnostic performance of CAD software against experienced radiologists.
  • To assess the applicability of CAD CXR using images captured by mobile phones.

Main Methods:

  • A retrospective pilot study analyzed 498 CXRs from Guinea-Bissau and Ethiopia.
  • Computer-aided detection (CAD) software (qXR) interpretation was compared with two experienced radiologists.
  • Reference standards included Xpert MTB/RIF confirmed PTB and clinical/laboratory findings.
  • Analysis included CXR images captured via mobile phones and digital cameras.

Main Results:

  • The CAD software achieved an area under the curve (AUC) of 0.84 for Xpert-confirmed PTB cases.
  • CAD CXR demonstrated a sensitivity of 76.5% and specificity of 85.9%.
  • Performance was comparable to experienced radiologists, with moderate agreement (κ=0.56) between CAD and radiologists.

Conclusions:

  • Computer-aided detection (CAD) CXR software performs comparably to experienced radiologists for pulmonary TB detection.
  • CAD CXR is a viable tool to support physicians in low-resource settings with limited access to radiologists.
  • The technology shows promise for improving TB diagnosis accuracy using mobile-captured radiographic images.
