In plain English

This 1979 article was a general overview of computerized tomography (CT) scanning. It did not report a new study of patients and did not study asbestos exposure. The authors, from the Department of Radiology at the New England Medical Center Hospital in Boston, described how CT works and how it developed. They then went through its uses by body region: head, face and neck, chest, abdomen and retroperitoneum, pelvis, and extremities. Asbestos-related disease came up only once. In the chest section, the authors wrote that because CT shows the pleural surface, it can be of tremendous value in diagnosing asbestosis, benign and malignant tumors, and pleural infections. They gave no data on asbestos-exposed patients. They reported operating costs that varied by institution but were upwards of $300,000 to $350,000 per year for a CT facility, with an average minimum volume of 3,000 cases and excluding equipment financing. They also stated that a CT scan carries no more radiation than a conventional barium enema exam. The authors concluded that for some patients CT is a life-saving technology. A separate editor's commentary, summarizing other researchers' studies, followed the article.

What the study did and found

• Design: Narrative overview (non-systematic review) of CT scanning and its clinical uses; no original study
• Who was studied: None; no patients or workers were studied
• Exposure: Not studied. The article concerns a diagnostic imaging technique, and asbestosis is mentioned once as a condition CT can help diagnose
• Main results:
  • The authors stated that because CT shows the pleural surface, it can be of tremendous value in diagnosing asbestosis, benign and malignant tumors, and pleural infections. They gave no supporting data.
  • The authors stated that CT is painless and noninvasive and carries no more radiation than a conventional barium enema exam.
  • The authors reported that operating costs vary from institution to institution but are upwards of $300,000 to $350,000 per year for a CT facility. This estimate was given with an average minimum volume of 3,000 cases and excluded the costs of financing the equipment.
  • The authors stated that CT has replaced conventional chest tomography in many institutions.
• The authors' conclusion: The authors concluded that CT is a life-saving technology for some patients. For others, they wrote, it can save prolonged hospitalization, unnecessary surgery and further diagnostic tests.
