    Notizen: Abstract  The goal of this work was to evaluate the costs and benefits of percutaneous interventional radiological procedures (PIRP) in terminal cancer patients, from the perspective of the Radiodiagnostics Department. The subjects were 225 patients who underwent different kinds of treatments, such as placement of endovenous or urinary stents, percutaneous gastrostomy, alcoholization of metastatic disease, celiac plexus block, tumor embolization, and inferior vena caval filter. We retrospectively analyzed the consequences in terms of survival, quality of life and cost ratios and found that this study fully justifies the use of interventional radiology in palliative oncology: 60% and 40% of the patients, respectively, were still alive at 1 month and 3 months; the additional cost of PIRP procedures is low (〈12%) compared with the total cost of hospitalization.

    Notizen: Abstract The purpose of this study was to analyse the sonographic patterns of solitary solid liver lesions in cancer patients and to evaluate the diagnostic accuracy of ultrasound alone and in combination with other techniques (liver function tests, histology). A total of 422 solitary solid liver lesions (SSLL) were diagnosed by ultrasound in cancer patients; 197 lesions were benign and 225 malignant. The predominant aetiology for hypoechoic SSLL (128 cases) was metastasis (112 cases), whereas most hyperechoic SSLL (265 cases) were haemangiomas (155 cases) rather than a metastasis (86 cases). The 29 isoechoic SSLL included 27 metastases and 2 benign lesions. A halo was found to be highly predictive of malignancy (97%–100%). The positive predictive value for malignancy of an SSLL was very high when the results of liver function tests were abnormal (97%–100%). In our experience, histological proof is unnecessary in the majority of liver lesions in cancer patients.

    Notizen: Abstract The natural width of a hypersatellite line (K −2→K −1 L −1 transition) has been measured for the first time. In the case of Cu (Z=29) this width has been found equal toΓ = 5 eV, i.e. much larger than that of the diagram (K −1→L −1) line. This result follows a proposed empirical law assuming this width to be equal to 3Γ K+ΓL.
