Positron Emission Tomography01:29

Positron Emission Tomography

6.2K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Magnetic Resonance Imaging

7.5K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

X-ray Imaging01:24

X-ray Imaging

7.7K
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...

Ultrasonography01:17

Ultrasonography

6.5K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

1.7K
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...

Area of Science:

  • Radiology
  • Medical Informatics
  • Natural Language Processing

Background:

  • Radiology reading involves manual annotation of imaging studies, which is time-consuming.
  • Current annotation methods lack standardization, leading to inconsistencies in reporting.
  • Free-text descriptions and predefined lists are often inefficient and non-standardized.

Purpose of the Study:

  • To develop and evaluate an automated approach for suggesting radiology finding descriptions.
  • To improve the efficiency and standardization of the image annotation workflow.
  • To reduce the manual effort required for radiology report generation.

Main Methods:

  • An approach was developed to extract and present finding descriptions from prior patient reports.
  • The system leverages textual information from historical radiology reports.
  • The solution was integrated into a Picture Archiving and Communication System (PACS).

Main Results:

  • The system demonstrated a reduction in keystrokes by up to 86% in approximately 38% of instances.
  • The approach was tested using 133 finding descriptions from routine oncology workflows.
  • Successful integration into a PACS environment was achieved.

Conclusions:

  • The proposed system enhances image annotation workflow efficiency in clinical settings.
  • The approach promotes greater standardization of finding descriptions in radiology reports.
  • This method offers a practical solution for optimizing the radiology reading process.
