Reviews in radiology informatics: establishing a core informatics curriculum.

The advent of digital imaging and information management within the radiology department has prompted the growth of a new radiology subspecialty: Radiology Informatics. With appropriate training, radiologists can become leaders in Medical Informatics and guide the growth of this technology throughout the medical enterprise. Radiology Informatics fellowships, as well as radiology residency programs, provide inconsistent exposure to all the elements of this subspecialty, in part because of the lack of a common curriculum. The Society for Computer Applications in Radiology (SCAR) has developed a curriculum intended to guide training in Radiology Informatics. This article is the first in a series presented by SCAR and the Journal of Digital Imaging, titled "Reviews in Radiology Informatics." The series is designed to sample from each of the major components in the Radiology Informatics Curriculum, to spark further interest in the field and provide content for informatics education.

Understanding interpretive errors in radiologists learning computed tomography colonography.

RATIONALE AND OBJECTIVES: To determine if interpretive errors in the course of learning CT colonography are secondary to failures in detection or in characterization and determine the types of lesions frequently missed. MATERIALS AND METHODS: Fifteen radiologists completed an electronic CTC training module consisting of two parts: 1) a teaching file demonstrating the varied appearances of polyps, cancers, and pitfalls in interpreting exams; and 2) a test of 50 complete CTC datasets. Following review of each test case, radiologists were asked to indicate if and where a polyp was visualized. The module then showed each neoplasm (if any) located within the dataset. For false negative examinations, radiologists indicated if the lesion was not seen, was seen but interpreted as colonic wall or fold, or was seen but interpreted as stool or fluid. RESULTS: The average sensitivity for sessile, pedunculated, and flat polyps for these novice readers was 76%, 63%, and 32%, respectively. Average sensitivity for all morphologies of cancers (annular, polypoid, flat) was high (93%, 85%, 95%), with 8/11 missed cancers being secondary to failure in detection. The most frequently missed cancer was an annular constricting tumor (5/11). Overall, 55% (73/132) of errors were failures of detection and 45% (59/132) were errors in characterization. CONCLUSION: Radiologists learning CT colonography had slightly more errors of detection than characterization, but this difference was not statistically significant. Flat and pedunculated polyps and annular constricting cancers were the most frequently missed morphologies. Examples of these abnormalities should be emphasized in CTC training programs.

Glomus tumor of the trachea: value of multidetector computed tomographic virtual bronchoscopy.

Glomus tumor of the trachea is extremely rare. We report a case of tracheal glomus tumor in a 39-year-old man who presented with hemoptysis. The diagnosis was made after bronchoscopic biopsy of a tumor involving the posterior wall of the upper trachea. Thin-section multidetector computed tomography of the chest was performed before surgical resection, with multiplanar re-formations and 3-dimensional virtual bronchoscopic reconstruction. Tracheal sleeve resection with reconstruction was successful, and pathological studies confirmed complete resection and the diagnosis of glomus tumor. The patient was disease-free 3 months postoperatively. To our knowledge, this is the first reported case in which additional computed postprocessing was used to help evaluate the extent of such a tumor.

The electronic imaging technology specialist: the role of a new radiology subspecialty for the 21st century.

Modern radiology departments need radiologists who understand subjects not thoroughly addressed during residency training: picture archiving and communication system (PACS) technology and administration, usability and acceptance testing, workflow analysis, digital image acquisition, compression, and quality control. A structured Electronic Imaging and Technology (EIT) fellowship program focusing on practical, technical, and administrative aspects of electronic imaging, teleradiology, and PACS was formed at the Mayo Clinic, Rochester, Minnesota. We review the rationale for dedicated EIT training, define its core curriculum, and discuss the purpose of an EIT specialist. Resources necessary to optimize this fellowship are discussed. Scheduling and coordination with clinical training is presented. The responsibilities and deliverables expected of an EIT fellow are examined. We differentiate the EIT fellowship from an Informatics fellowship and explore the role an EIT specialist within a department. An EIT fellowship provides practical and valuable skills, and can be compared to the added expertise gained through established fellowship training programs.

Radiologic case study. Glenolabral articular disruption (GLAD) lesion.

Glenolabral articular disruption lesions are an unusual source of anterior shoulder instability and pain. They may be difficult to diagnose clinically and often require surgical repair. Magnetic resonance arthrography is superior to other imaging techniques, including conventional MRI, in the evaluation of shoulder instability.
