Introduction Ultrasound is integral to modern gynaecological practice. This has been recognised by bodies such as the Royal College of Obstetricians and Gynaecologists, who have made ultrasound part of the core requirements in their training modules. Assisted conception units have…
Introduction Scrotal sonography was first introduced in the mid-1970s. It remains the imaging modality of choice because it is simple, relatively inexpensive, and quick. Continuing refinements in imaging technology with higher-frequency transducers, and increased Doppler sensitivity have greatly enhanced perception…

Introduction Common indications for penile imaging are for evaluation of erectile dysfunction, trauma, priapism, penile carcinoma and Peyronie’s disease. Because it is a…
Indications The most important use of colour Doppler imaging of the prostate remains as an aid in cancer detection. This is particularly relevant in patients in whom cancer is suspected based on prostate specific antigen (PSA) elevation without obvious tumour…

Renal Vascular Doppler Ultrasound Ultrasound is the imaging modality of choice for evaluation of the kidneys, especially in patients with borderline renal function, the incidence of which is increasing. In comparison with other modalities, ultrasound has the distinct advantage of…
Introduction There have been impressive advances recently in the application of ultrasound contrast medium to liver imaging; but these agents are not universally available. Researchers have shown the benefits of microbubble-enhanced lesion detection and characterisation. Unfortunately governing agencies across the…
Arteriovenous Fistulas and Synthetic Arteriovenous Grafts At the end of 2009, there were 571,414 patients being treated for end-stage renal disease in the United States with 116,395 new cases in that year ; approximately 65% of these patients received haemodialysis.…
Doppler examination in the abdomen is associated with specific problems which are not encountered in peripheral vascular examinations and these are particularly relevant to examinations of the aorta, inferior vena cava and their associated vessels. Respiratory motion and cardiac pulsation…
The peripheral veins may be affected by a variety of disorders which can be assessed by ultrasound. Deep vein thrombosis (DVT) and thromboembolic disease are the most common indications for investigation of the peripheral veins but venous insufficiency and vein…
