Abstract

|
|
9 Patients with bronchogenic carcinoma and 6 patients with mediastinal mass were studied by MR imaging to determine the presence of chest-wall invasion or mediastinal invasion.
All studies were carried out at 0.5 T and were interpreted before surgery. MR findings indicative of chest invasion included a high signal focus within the chest wall and/or chest-wall thickening with increased signal on T2-weighted images.
Coronal and sagittal imaging facilitated identification of tumor contiguity with extrathoracic structure, in apical lesions.
Sensitivity & specificity of unresectibility for 11 malignant tumors were 88% and 33% respectively.
Sensitivity & Specificity of unresectibility for benign tumors were 100% and 100% respectively. Thus, we concluded MR imaging is useful in the evaluation of chest wall & mediastinal invasion by the thoracic tumors.
