Myocardial lesions subsequent to roentgenotherapy.

The myocardium was studied for changes caused by therapeutical X-ray irradiation in a necropsy material of 14 cases. The lesions found in the myocardial vessels, in the parenchyma and in the interstitium are described in detail. While the severity of the vascular changes was independent of the radiation dose, the gravity of parenchymal lesions was closely related to the dose employed.
