RESUMO
Imaging of the female pelvis by ultrasound may be carried out either by the use of trans-abdominal probes or, more recently with trans-vaginal probes also. The relative merits of the two are discussed in this paper with special referencwe to the diagnosis of abnormalities in the first six to eight weeks of pregnancy. The advantages of the trans-vaginal probe in the investigation of infertility and the process of ovum retrieval for in-vitro fertilization are outlined. (AU)

Two cases are presented which illustrate the radiological drawbacks and advantages of air when it is present either around or within an organ of clinical interest. The physical principles underlying this anomaly are briefly discussed, particularly in relation to plain film radiology and ultrasonic imaging. The importance of recognising this phenomenon and the diagnostic difficulties which may arise stressed

The ultrasonic detection of pre-sinusoidal portal vein obstruction is described in a patient with clinical features of alcoholic liver disease. The case illustrates the advantages of ultrasound in the evaluation of the portal circulation, including unusual radiological observations of the portal circulation
