|February 24, 2001
Summary
Contrast radiography is valuable for confirming the position of radio-opaque long lines in neonates when plain films are unclear. This imaging technique aids in accurate line placement and subsequent repositioning when necessary.
Area of Science:
- Neonatal imaging
- Pediatric radiology
- Vascular access
Background:
- Accurate placement of radio-opaque long lines is crucial for neonatal care.
- Plain radiography is the standard initial method for assessing line tip position.
Purpose of the Study:
- To evaluate the effectiveness of contrast radiography compared to plain radiography for determining neonatal long line tip position.
Main Methods:
- A prospective study involving neonatal patients requiring radio-opaque long lines.
- Plain radiography was performed initially; contrast radiography was used if the tip was not visible.
Main Results:
- Contrast radiography was necessary in 31 of 62 assessed lines.
- Contrast successfully visualized the line tip in 29 of these cases.
- Eight lines requiring contrast were repositioned due to suboptimal tip placement.
Conclusions:
- Intravenous contrast administration should be a routine part of assessing long line tip position in neonates.
- Contrast radiography enhances diagnostic accuracy for line placement in this population.

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...

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...

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...
