[Results of radiotherapy in patients with stage-II Hodgkin's lymphoma with mediastinal lymph node involvement].

Depending on size of intrathoracic lymph nodes, 65 patients with Hodgkin's disease (stage II) were divided into two groups using the mediastinal-thoracic index (MTI): MTI = 0.22-0.3 prior to irradiation and MTI (0.

[Computerized and magnetic resonance tomography in the staging of lung cancer].

CT (157) and MRI (74) potential in lung cancer staging was studied. Central form was identified in 195 patients (75%). The data were compared in 34.

[Magnetic resonance tomography in the diagnosis of lung metastases in the mediastinum and thorax].

The results of MRI in 81 patients with morphologically verified lung cancer, mainly Stages IIIA and IIIB, were analyzed. They were compared with CT data in 37 cases and surgical findings in 28. MRI was performed by using Magnaview 0.

[Significance of computerized, magnetic resonance and ultrasound tomography in the diagnosis of spreading of pulmonary cancer to the mediastinum].

In 232 patients predominantly with the central type of lung cancer underwent echotomography (ET) (n = 16), CT (n = 142) and MRT (n = 55) in order to evaluate their possibilities in the diagnosis of the spread of a tumor process to the mediastinum and their impact on disease staging. The results of the techniques and the data of surgical interventions were compared: CT in 55 patients, CT in 70 and MRT in 22. The sensitivity of each method was determined by 3 parameters: 1) detection of intrathoracic lymphadenopathy; 2) diseased mediastinal large vessels; and 3) cancer spread to the pleura, pericardium, heart, and chest.

[Potentialities of ultrasound and computed tomography in the diagnosis of metastases of lung cancer in the mediastinal lymph nodes].

The results of routine roentgenotomography, CT and USI in the diagnosis of intrathoracic metastases of lung cancer were compared in 69 patients (central type--52, peripheral--17). These results were compared with operative findings in 45 patients. The sensitivity of USI in the diagnosis of enlarged paravasal lymph nodes exceeded that of roentgenotomography and was slightly inferior to CT.
