OBJECTIVE Magnetic resonance imaging (MRI) and ultrasound scanning complement each other in screening for and diagnosis of endometriosis. Fusion imaging, also known as real-time virtual sonography, is a new technique that uses magnetic navigation and computer software for the synchronized display of real-time ultrasound and multiplanar reconstructed MR images. Our aim was to evaluate the feasib...

With ever increasing use of imaging as a diagnostic tool in medicine, medical schools are being urged to further integrate imaging into their curricula. Ultrasound is one such way of doing so-enabling students to bridge the gap between form and function, medical school and clinical practice. As a non-invasive imaging technique, with low risk when compared to other methods of imaging, ultrasound...

OBJECTIVES This study was designed to evaluate the changes in intrastent and angiographic dimensions when intravascular ultrasound imaging is used to direct the deployment of balloon-expandable Palmaz-Schatz stents in coronary arteries and saphenous vein grafts. BACKGROUND Intravascular ultrasound provides more information than angiography in the imaging of intravascular structures. Previous ...

Ultrasound imaging is the most commonly used imaging system in medical field. Main problem related to this imaging technique is introduction of speckle noise, thus making the image unclear. The success of ultrasonic examination depends on the image quality which is usually retarded due to speckle noise. There have been several techniques for effective suppression of speckle noise present in ult...

Today’s ultrasound imaging systems produce better images and display more information than it was possible to display 30 years ago. Similarly, performance criteria for ultrasound imaging systems and the tools used to make these measurements have evolved, and have become more complex. This presentation will informally discuss a few examples of the evolution of ultrasound imaging systems and perf...

Acute pelvic pain in pregnancy presents diagnostic and therapeutic challenges. Standard imaging techniques need to be adapted to reduce harm to the foetus from X-rays because of their teratogenic and carcinogenic potential. Ultrasound remains the primary imaging investigation of the pregnant abdomen. Magnetic resonance imaging (MRI) has been shown to be useful in the diagnosis of gynaecological...

Ultrasound is an essential modality within musculoskeletal imaging, with the recent addition of elastography. The elastic properties of tissues are different from the acoustic impedance used to create B mode imaging and the flow properties used within Doppler imaging, hence elastography provides a different form of tissue assessment. The current role of ultrasound elastography in the musculoske...

diagnosis and prediction of recovery. Among the various modalities of imaging, spinal ultrasound appears to be very promising and hence is recommended as the first modality of imaging(4). However, it should be remembered that changes are known to occur in the lesion over time and a single ultrasound may not pick up all lesions. Hence, it is not surprising that ultrasound of the cervical spine w...

Endoanal ultrasound is now regarded as the gold standard for evaluating anal sphincter pathology in the investigation of anal incontinence. The advent of three-dimensional ultrasound has further improved our understanding of the two-dimensional technique. Endoanal ultrasound requires specialised equipment and its relative invasiveness has prompted clinicians to explore alternative imaging techn...

Ultrasound can be an effective alternative to computed tomography for surveillance following endovascular aneurysm repair (EVAR). Recently, ultrasound fusion imaging with the real-time navigation system was introduced. Here we described 3 patients who underwent post-EVAR surveillance using this novel technique. Complete coregistration was achieved in all patients. The origin of left renal arter...
