The ultrasonographic appearance of hepatic hemangiomas was studied in 19 patients (31 lesions). The detectability rate by real-time ultrasonography was 77%. A hyperechoic, sharply-marginated and internally homogeneous lesion is highly suggestive of hemangioma. If the hypoechoic lesion has homogeneou

A brief survey of electrochemical methods which can be employed to respond to the challenge of measuring electroactive species in untreated solutions in real-time is made. Particular attention is given to the advantages that can be obtained from miniaturization and protection of the electrode surfac
