Carbon dioxide digital subtraction angiography in oncological-interventional radiology.

Aims And Background: The aim of this work is to demonstrate the usefulness of carbon dioxide, used as contrast agent, in special indications in vascular interventional oncological procedures.

Methods: We studied 40 patients with digital subtraction angiography enhanced with CO2 as a contrast agent. At the same time we utilized also, in all cases, jodinated contrast agent to evaluate the different opacification gradient, the different viscosity range and the different perfusion.

[Self-expanding metal stents in the treatment of neoplastic esophageal stenosis. The technic and preliminary results].

Self-expanding metal stents have been recently used for the treatment of neoplastic esophageal stenoses. In our series, nitinol Strecker stents were implanted in ten patients with malignant esophageal intrinsic or extrinsic strictures, as a definitive palliation. Thirteen stents in all were used: two stents were positioned in three patients to recanalize the esophagus.

Conventional radiographic follow-up in the irradiated lung.

Aims: To highlight the different changes induced in lung tissues by various forms of radiotherapy (RT) according to tumor site and type.

Methods: A retrospective analysis of the roentgenographic evaluation of and long-term follow-up data on 2375 patients who received RT for various intrathoracic and extrathoracic tumors at the National Cancer Institute of Milan.

Results: The iconographic patterns of post-RT changes, grouped by site and type of tumor and RT procedure and described in detail, afford deeper insight into a little-known area of lung pathology.

Radiobiologic and pathologic characteristics of the irradiated lung and roentgenographic aspects.

Aims: Experimental radiobiologic factors help to better understand and interpret the development of radiographic alterations in lung tissues due to radiant treatments. In this paper the authors summarize the radiologic factors and technical bases about radiotherapy of the lung.

Methods: The conventional radiologic iconography has been examined in a large series of patients (n = 2151) with iatrogenic pulmonary lesions determined by various types of antineoplastic radiant treatments at the Istituto Nazionale Tumori of Milan.

Adrenal gland metastasis in osteogenic osteosarcoma. A radiological case report.

Adrenal gland metastases from osteogenic sarcoma are rare and an unusual pattern of relapse. The recognition of solitary metastases, particularly when located in uncommon sites is very important for subsequent treatment. The authors describe the radiological features of an adrenal metastases from osteogenic sarcoma.
