Summary
Radiologists have been integral to the National Medical Association (NMA) since 1909. This article highlights their significant contributions and the establishment of the Section on Radiology within the NMA.
Area of Science:
- Medical History
- Radiology
- Professional Associations
Background:
- The National Medical Association (NMA) was founded in 1895, the same year as the discovery of X-rays.
- Radiologists' engagement with the NMA began early, with Dr. Marcus F. Wheatland's influential 1909 lecture and subsequent presidency.
Observation:
- Dr. Wheatland's presidency in 1910 marked a significant early involvement of radiologists in the NMA leadership.
- More recently, Dr. Tracy M. Walton served as president during the NMA's centennial year.
Findings:
- The article documents the historical and ongoing participation of radiologists within the NMA.
- It specifically details the establishment of the Section on Radiology in 1949.
- Dr. William E. Allen, Jr. was the inaugural chairman of the Section on Radiology and a prominent figure in radiology and the NMA.
Implications:
- This historical overview underscores the deep-rooted connection between radiology and the NMA.
- It highlights the leadership roles radiologists have played in advancing medical practice and professional organizations.
- The founding of the Section on Radiology signifies a formal commitment to the specialty within a major medical association.

01:30Radiological Investigation I: X-ray and CT
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 the...
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...
01:30Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...

01:30National Nursing Organizations II
Nursing organizations play a vital role in representing nurses working in specialized clinical settings, such as the American Association of Critical-Care Nurses (AACN).
The AACN emphasizes a healthy work environment through six standards to achieve an optimal patient outcome. The standards are appropriate staffing, meaningful recognition, collaboration, authentic leadership, effective communication, and decision-making. In addition, AACN provides certification programs, webinars, journals, and...

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...

01:26National Nursing Organizations I
Nursing organizations assume a significant role in consistently developing the nursing profession through education, research studies, establishing practice standards, and reforming health policies. Typically, nursing organizations operate at the regional, national, and international levels. For example, the International Council of Nurses (ICN) represents more than 28 million nurses worldwide. In contrast, the American Nurses Association (ANA) is a membership organization representing nurses...
