“…The supine chest radiograph will often underestimate the volume of pleural fluid. 51 Subpulmonic effusions occur when pleural fluid accumulates in a subpulmonic location. They are often transudates and can be difficult to diagnose on the PA radiograph and may require a lateral decubitus view or ultrasound.…”

“…Furthermore, high accuracy of 94 % was calculated. For detecting pathologies like pleural effusion and pneumonia on chest radiographs in the supine position, sensitivities/specificities/accuracies of 67 %/70 %/69 % [18] and 65 %/93 %/ 67 % [19], respectively, were reported. Due to the small number of patients that underwent CTCA and thoracic CT during the same imaging session, decided subdivision of sensitivities, specificities, and accuracies for the different pathologies could not be analyzed in our study.…”

Purpose: To evaluate the incidence of additional thoracic pathologic findings (TPF) detected on scout views and corresponding bolus tracking slices (SVBT) for computed tomographic cerebral angiography (CTCA) and to test the reliability and accuracy of these findings. Materials and Methods: The study collective included 505 consecutive patients who underwent multidetector CTCA. Appendant SVBT of all patients were reviewed for any pathologic findings and patient medical reports were analyzed, if any medical treatment was initiated for the detected pathologic findings. In 18 patients thoracic CT scans were performed in the same session. These were additionally reviewed by two blinded observers to test for intra- and interobserver reliability as well as for accuracy of detecting thoracic pathologies on SVBT. Results: TPF were detected in 165 (33?%) SVBT. The five most common pathologic findings were: pleural effusion, 12?%; pneumonia, 8?%; atelectasis/dystelecatsis, 6?%; pericardial effusion, 2?% and elevated diaphragm, 1?%. For 48?% of these findings medical treatment was initiated. SVBT showed a sensitivity of 53?%, a specificity of 99?%, a positive predictive value of 89?%, a negative predictive value of 94?% and accuracy of 94?% for the detection of TPF. The intraobserver reliability was very good and the interobserver reliability showed moderate agreement. Conclusion: SVBT for CTCA should be reviewed with care by radiologists, since additional TPF can affect patient management. Nevertheless, despite a high specificity of SVBT for detecting TPF, an only moderate sensitivity has to be taken into account. Key points: ??Thoracic pathologies are frequently found on scout views for cerebral CTA ??Reviewing additional bolus trigger slices will improve diagnostic sensitivity ??Despite high specificity, scout views and trigger slices offer a moderate sensitivity ??Evaluation of scout views and trigger slices can result in medical treatment Citation Format: ??Groth M, Fiehler J, Henes FO et?al.
