ABSTRACT
Fifteen patients with hydatidosis, 13 with hepatic echinococcosis and two with isolated lesions of the spleen and the shoulder, were examined with magnetic resonance (MR) imaging. Of the 13 patients with hepatic hydatidosis, four had secondary peritoneal lesions, and one also had involvement of the dorsal spine. The presence of a hypointense rim and a multiloculated or multicystic appearance are distinctive features. When evaluating the viability of hydatid cysts the authors found that MR imaging findings were not particularly valuable, as the MR imaging signs (daughter cysts and detachment of the membranes) are rare and are also evident at computed tomography and ultrasound examinations. T2 measurements were not useful due to the wide range of values obtained. Despite these limitations, MR imaging is still an important technique in the study of echinococcosis to depict the presence of a rim as a characteristic sign and to obtain a complete anatomic evaluation.

Galactography is the most important instrumental examination in the diagnostics of secreting breast. The authors describe the direct radiologic pictures of the galactoforous ducts as well as the changes of the ductal walls and lumen as shown by the radiologic examination by contrast media. The study finally reports statistical data concerning a personal case-series of 324 patients presenting surgically managed breast secretion and divided according to age. This analysis shows that the highest incidence of galactophoritis, secreting ductal ectasia and fibrocystic mastopathy occurs between 31 and 50 years of age, whereas papilloma, intraductal papillomatosis and carcinoma are more frequently observed between 41 and 60 years.

The use of dynamic lymphadenoscintigraphy is proposed for the study of the lymphatic flow in the lower limbs. The method is based on the determination of the flow curves of radiocolloid (antimony-sulphide labelled with 99mTc) in the lower limbs, on the time of its appearance in the inguinal lymphatic vessels and in the liver, and also on the recording by periodically repeated photoscans of the progress of the radiocolloid in the pre-lymph node ducts. Thus, the method is suggested for use in the observation of flow variations as an expression of metastatic or systemic lymph node diseases and in the differential diagnosis of lymphatic and venous oedema.
