A considerable dose reduction without loss of diagnostic information is achievable in dental CT. As radiation exposure of the presented low-dose protocol is expected to be in the same range as DVT, low-dose dental CT might be superior to DVT, because CT can be used to evaluate soft tissues as well.

A considerable dose reduction without loss of diagnostic information is achievable in dental CT. Dose-reducing examination protocols like the one presented may further expand the use of preoperative dental CT.

21 years after radiotherapy for breast cancer, a 63-year-old woman developed a malignant mesenchymoma of the chest wall. The total irradiation dose was 132 Gy. The first clinical symptom of this second malignancy was a slight irregular calcification around the implanted silicon protheses observed in a conventional chest X-ray. Radiation-induced sarcoma is a very rare complication of radiotherapy. In cases of chest wall calcification after radiation therapy further investigation should be carried out, because some patients with radiation-induced sarcoma could be saved, if an early diagnosis is reached.
