the Silhouette Sign revisited
Respiration, 2000Co-Authors: Vernon J Louw, Adrian Schmidt, C T BolligerAbstract:Accessible online at: www.karger.com/journals/res A 60-year-old woman with chronic obstructive airways disease and a history of strong smoking presented with acute bronchospasm precipitated by an episode of acute bronchitis. At the same time, she complained of anterior pleuritic chest pain on the left side. On examination, a large area of decreased aeration which was dull on percussion was found anteriorly on the left side, especially in the upper lung zone. A chest X-ray (fig. 1) demonstrated a large, irregular-shaped, but well-demarcated mass lesion in the left lung on the posteroanterior view. A second, smaller lesion is seen in the left lower-lung zone. What is nicely demonstrated is that the aortic knuckle and the left pulmonary artery are well demarcated, which indicates – deducing from the rule of the Silhouette Sign – that the larger mass lesion is located neither posteriorly nor in the ‘middle’ (i.e. between anterior and posterior) lung zone. On the other hand, the mass partially obscures the left heart border. Therefore, taking everything into account, one can firmly conclude from the posteroanterior view alone that the mass is situated anteriorly. This was confirmed on the lateral view (not shown) and also on a CT scan of the chest (fig. 2), the latter being performed to obtain an image-guided needle biopsy. Inoperable adenosquamous carcinoma of the lung was diagnosed and the patient was referred for radiotherapy.

Comparison of Traditional and Web-Based Medical Student Teaching by Radiology Residents.
Journal of The American College of Radiology, 2019Co-Authors: Fariha Kamal, C. Lynn Cabral, Judy H. SquiresAbstract:Abstract Purpose Web-based learning tools are increasingly available for use and have been described in the pedagogical literature. However, rigorous comparisons between traditional learning methods and newer collaborative online tools have not been performed. Herein, we describe a web-based curriculum hosted on the collaborative Radiopaedia.org website. This curriculum was compared with traditional learning tools in a randomized, controlled fashion. Materials and Methods Medical students rotating through inpatient pediatrics were offered a 1-hour case-based learning session led by radiology residents. Students were randomized to receive online ( Radiopaedia.org ) versus traditional supplemental educational materials (reading material covering the same content) for review before the in-class session. A 15-point questionnaire was administered at two different points during the rotation: at the beginning of the clinical rotation and at the end of the classroom session. Results Fifty-eight students were approached for enrollment and a total of 47 (81%) consented to participation and completed the study requirements. Students who completed the web-based module had higher mean knowledge scores (74%) compared with those who were provided the traditional learning material (68%) (P = .06). Specifically, they demonstrated increased knowledge of the ACR Appropriateness Criteria and the “Silhouette Sign.” Conclusions A randomized, controlled, nonblinded evaluation of a novel radiology curriculum intervention hosted on Radiopaedia.org demonstrates improved test scores compared with traditional teaching methods.
