One hundred and twenty patients with bronchogenic carcinoma were prospectively studied by both computed tomography (CT) and magnetic resonance imaging (MRI) during the 2 weeks preceding thoracotomy or mediastinoscopy. MRI scans included contiguous axial and coronal slices. Results of CT and MRI studies were compared with the surgical and pathological findings on the basis of the TNM classification. Although no significant difference was found between the two imaging methods for the evaluation of tumour extent, MRI appears to be a valuable imaging technique for left upper lobe and apical neoplasms. Comparison between the two techniques for mediastinal node evaluation showed that sensitivity of MRI is superior to CT in the left paratracheal, aortopulmonary and subcarinal node areas.

The aim of this study was to assess the value of long-term treatment with 60 mg per day of trimetazidine, a cellular antiischemic agent, in comparison with placebo, in patients with ischemic cardiomyopathy controlled by conventional treatments. Twenty patients, with a mean age of 59.5 +/- 1.6 years, suffering from severe ischemic cardiomyopathy (NYHA IV, 6 patients; NYHA III, 14 patients) confirmed by coronary angiography, were included in the study; four of them suffered from residual angina. All of these patients were receiving long-term treatment with long-acting nitrates associated with digitalis (9 patients), diuretics (15 patients), anticoagulants (13 patients), and antiarrhythmics (11 patients), and were considered to be stabilized at the time of inclusion in the study. The examinations consisted of clinical and laboratory assessment, resting ECG, 24-hour ECG monitoring, X-ray evaluation of cardiac volume (CV), and evaluation of echocardiographic left ventricular shortening (ELVS) and of isotopic ejection fraction (EF). These three parameters were expressed as a percentage variation with respect to the initial value, and their variation between the two groups was compared by means of two-way analysis of variance. Clinically, the therapeutic benefit provided by trimetazidine resulted in: a) an improvement of dyspnea in all patients treated with trimetazicine compared with only one patient with placebo (p less than 0.001), b) resolution of residual angina, which was unchanged with placebo, c) reduced requirements for complementary treatments (a single case versus eight cases in the placebo group; p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
