Trainig Software for Pulmonary Nodule CXR Identification
Chest X-rays (CXRs) are widely used in clinical settings. However, pulmonary nodules located in CXR blind spots, e.g., the mediastinum, diaphragm, and pulmonary hila, are more difficult to detect than when located in a lung field, i.e., upper lung field, middle lung field, or lower lung field. Thus, this teaching software has been developed for better understanding of such blind spots on CXRs. In order to make it easier for our users to understand the relationship between the location of pulmonary nodules on chest CT images and on CXRs, it is assumed that the X-ray beam is vertical to the film in the "Basic" case and in Case 5.
This study was supported by Grants-in-Aid from the Ministry of Health, Labor and Welfare for the 3rd-term Comprehensive 10-year Strategy for Cancer Control (Noriyuki Moriyama, Ryosuke Tsuchiya), the Clinical Cancer Research (Masahiko Kaneko) and for Cancer Research, 21S-1 (Yasuhiro Fujiwara).
We hope that this training program will help radiologists and medical stuff recognize the dangerous zone of CXRs allowing them to detect pulmonary lesions more easily and more effectively.
