Chemonucleolysis.
In November 1982, the Federal Drug Administration approved Chymodiactin, chymopapain in injection form, for the treatment of herniated intervertebral discs. This procedure, termed chemonucleolysis, requires radiologic support. This article describes the anatomy, pathology, and special techniques related to chemonucleolysis and defines the role of the radiologic technologist in the completion of this procedure.
Pneumoconiosis: an occupational hazard.
The use of radiography to detect pneumoconiosis is a familiar task to radiographers in coal mining states. This article includes a discussion on pneumoconiosis and coal workers' pneumoconiosis (black lung) as well as the radiographic findings associated with pneumoconiosis and the federal act that established the black lung program in the United States.
Magnification radiography.
Magnification radiography is the purposeful production of an image larger than the object being studied. This technique can be utilized to image detail that is not resolvable by normal means. An overview of magnification radiography, including the physics and equipment considerations, is presented to better acquaint the radiographer with this increasingly popular technique.
Carpal tunnel syndrome: the role of radiography.
Carpal tunnel syndrome is a common neurologic condition that is evaluated often using radiography. An overview of carpal tunnel syndrome and its diagnosis is presented, along with methods for radiographic evaluation of this condition.

Skeletal variation: biological and cultural.
Radiographic examinations may reveal skeletal variations that are biological or cultural in origin. This article reviews both types of variations, discusses radiographic examples, and explains how radiographs can be helpful in the field of anthropology.
Hazards of ferrous materials in MRI: a case report.
Magnetic resonance imaging is a new technology that is free from the hazards of ionizing radiation. However, the technology utilizes intense magnetic fields and there is a risk of ferrous objects becoming projectiles if brought too close to the magnet. This case report describes an accident where a large metallic body was drawn into the bore of the magnet, seriously injuring an individual in its path.
Prospective payment and its impact on radiologic technology.
The prospective payment system is affecting the management and delivery of health care, and will have a large impact on the radiology department. This article describes the prospective payment system and explains how the role of the radiologic technologist may be altered.
The radiographic appearance of a ceramic total hip replacement.
A new total hip replacement has been approved for use in the United States. This system utilizes ceramic articular components and a metal stem. This article reviews the history of total hip replacement (THR) and the construction and advantages of the ceramic total hip replacement. Additionally, the radiographic appearance of current THR systems are compared with the new systems.
