Radiology
|July 1, 1975
Summary
Diagnostic image quality via interactive television was assessed. Teleradiology interpretations of kidney, ureter, bladder, chest, and bone radiographs showed acceptable accuracy despite radiologist inexperience.
Area of Science:
- Medical imaging
- Radiology
- Teleradiology
Background:
- Interactive television systems offer potential for remote diagnostic imaging.
- Evaluating the diagnostic quality of teleradiology is crucial for its clinical adoption.
Purpose of the Study:
- To assess the diagnostic quality of roentgenographic images transmitted via interactive television.
- To determine the accuracy of remote radiological interpretations compared to direct viewing.
Main Methods:
- 100 kidney, ureter and bladder, chest, and bone radiographs were evaluated.
- Five radiologists interpreted images both directly and via a microwave-transmitted television signal.
- Receiver operating characteristic (ROC) curves and critical tables were used for analysis.
Main Results:
- Radiologists interpreted images transmitted via television with acceptable accuracy.
- Performance was considered adequate despite the participants' lack of prior teleradiology experience.
- Image quality was sufficient for diagnostic purposes in this setting.
Conclusions:
- Interactive television is a viable method for transmitting diagnostic radiological images.
- Teleradiology using this technology can achieve acceptable diagnostic accuracy.
- Further training may enhance performance in teleradiology applications.

01:24X-ray Imaging
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 X-rays, and by 1900, X-ray was widely...
01:10Computed Tomography
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...

01:29Positron Emission Tomography
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 being...

01:20Imaging Studies for Cardiovascular System III: X-Ray
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...
