Chest wall infiltration by lung cancer: value of thin-sectional CT with different reconstruction algorithms

Abstract: The aim of this investigation was to evaluate whether thin-sectional CT with different reconstruction algorithms can improve the diagnostic accuracy with regard to chest wall invasion in patients with peripheral bronchogenic carcinoma. Forty-one patients with intrapulmonary lesions and tumor contact to the thoracic wall as seen on CT staging underwent additional 1-mm CT slices with reconstruction in a high-resolution (HR) and an edge blurring, soft detail (SD) algorithm. Five criteria were applied and validate… Show more

“…To conclude, since the detection of ribs or muscular tumour invasion could be an indication to an adjuvant chemo-radiation treatment, the role of CT scan becomes crucial. Concerning chest wall extension, in addition to commonly used criteria (such as pleural contact area and chest wall-tumour angle), thin-sectional CT scan with specific software algorithms reconstruction can significantly improve the accuracy of CT to the level reached by MRI, as reported by Uhrmeister et al [11].…”

“…Thin-section CT imaging (1-mm slices) was found to be superior to conventional CT techniques (10-mm slices) for the delineation of anatomical chest wall structures and thus for evaluating the presence of chest-wall involvement [39]. For the delineation of the extrapleural fat plane and the assessment of soft tissue structures a smoothing reconstruction algorithm was found to be superior to a high-resolution (HR) algorithm because of the increased noise level in HRCT sections.…”

“…7) [2]. -mm-MSCT-Aufnahmen nach KM-Gabe mit Rekonstruktionen sind diagnostisch dickeren Schichten überlegen, können jedoch wegen des niedrigen Weichteilkontrastes kleine Infiltrationen nicht sicher erfassen [25]. Bei der Differenzierung echter pleuraler Verdickungen von fibrotischen Lungenparenchymveränderungen mit Pleuraanheftung kön-nen 3D-Rekonstruktionen auf der Basis von Oberflächendarstellung helfen [7].…”
