[High-resolution CT of the lung versus thoracic radiography after adjuvant radiotherapy in breast carcinoma].
We examined the lungs of 35 women following postoperative radiotherapy for breast cancer by using high-resolution computed tomography (HR-CT). Radiotherapy was performed on a cobalt 60 unit using a five-field technique. The average interval between the end of radiotherapy and HR-CT examinations was 23.8 months. HR-CT was limited to those lung areas that were at risk for radiation-induced changes. In 40% of patients minimal interstitial damage (e.g. thickened septal lines, curvilinear densities) invisible on chest x-ray was demonstrated by HR-CT. Massive fibrosis as reported by others was not seen in our study. We conclude that in case lung involvement is suspected clinically during or after radiotherapy, HR-CT is the method of choice for demonstrating these morphological changes.
