The following are highlights from the current issues of RSNA’s two peer-reviewed journals.
Imaging of occupational lung disease, often perceived as a static discipline, continues to evolve with changes in industry and imaging technology. The challenge of accurately identifying an occupational exposure as the cause of lung disease demands a team approach, requiring integration of imaging features with exposure type, time course and severity.
In a State-of-the-Art article in the March issue of Radiology (RSNA.org/Radiology), Christian W. Cox, M.D., of National Jewish Health in Denver, and colleagues demonstrate the importance of a multidisciplinary approach to diagnosing occupational lung disease, with particular emphasis on a radiologic pattern-based approach. In addition, the authors illustrate the spectrum of lung injury related to occupational exposures and discuss the imaging features of several newly described occupational diseases.
Increasing use of CT has demonstrated that specific occupational exposures can result in a variety of patterns of lung injury. The radiologist is often ideally placed to recognize potential occupational lung disease and question the clinician about possible exposures that, if causally relevant, may lead to more targeted medical management and prevention, according to the authors.
“The radiologist must understand the spectrum of expected imaging patterns related to known occupational exposures and must also recognize newly described occupational exposure risks, often related to recent changes in industrial practices,” the authors write.
Imaging has long been established as an essential element in the workup of clinically suspected lesions of the thyroid gland. While thyroid nodules are often detected incidentally at CT, MR imaging and PET, ultrasonography is the most commonly used imaging modality for characterizing the nodules.
Knowledge of the normal and abnormal imaging appearances of the thyroid gland is essential for appropriate identification and diagnosis of thyroid lesions, according to Arun C. Nachiappan, M.D., of Baylor College of Medicine, Houston, and colleagues, authors of an article in the March-April issue of RadioGraphics (RSNA.org/RadioGraphics). The authors discuss: imaging appearance of thyroid lesions with special emphasis on clinical background and radiologic-pathologic correlation; current indications for thyroid fine-needle aspiration biopsy (FNAB); proper ultrasound-guided FNAB technique; and cytologic analysis of the acquired specimen.
The critical roles of the radiologist in the management of thyroid disease are to decide whether to biopsy a nodule on the basis of ultrasound criteria and to use proper FNAB technique for thyroid biopsy, according to the authors.
“It is also important for the radiologist to have a basic knowledge of thyroid disease, be familiar with specimen processing, and recognize the cytologic appearances of thyroid lesions, all of which will facilitate a multifaceted understanding of the management of thyroid nodules,” the authors write.
