Editor—We thank Drs Gayer and Palte and Prof. Kumar for this important note regarding the technical side of using ultrasound for regional anaesthesia in eye surgery. We are aware of the potential risk of ultrasound waves, especially for sensitive structures like neuroretinal tissue. Our cadaver study was intended to prove the concept of a new technique without danger to patients. We investigate...

BACKGROUND Numerous studies have shown significant benefits of using real-time ultrasonography for central line intravenous access. Traditionally, the ultrasound probe is placed along the short axis of the vein to visualize and direct needle placement. This view has some limitations, particularly being able to visualize the needle tip. Some practitioners place the ultrasound probe in the long a...

Our objective is to permit in situ visualization of ultrasound images so that direct hand-eye coordination can be employed during invasive procedures. A method is presented that merges the visual outer surface of a patient with a simultaneous ultrasound scan of the patient's interior. The method combines a flat-panel monitor with a half-silvered mirror such that the image on the monitor is refl...

BACKGROUND AND OBJECTIVES The use of the ultrasound to guide the puncture in peripheral nerve blocks has become increasingly more frequent. With the lower probability of promoting vascular damage the ultrasound has become an interesting tool in peripheral nerve blocks especially in patients in use of anticoagulants or with coagulopathies. The objective of this article was to report two cases in...

BACKGROUND Necropsy studies demonstrate that coronary artery disease (CAD) is frequently complex and eccentric. However, angiography provides only a silhouette of the vessel lumen. Intravascular ultrasound is a new tomographic imaging method for evaluation of coronary dimensions and wall morphology. Few data exist regarding intravascular ultrasound in patients with CAD, and no data exist for su...

or more than 50 years, the goal of the American Institute of Ultrasound in Medicine (AIUM; Figure 1) has been to advance the art and science of ultrasound in medicine and research through its educational, scientific, and professional activities. The AIUM has achieved numerous accomplishments in its quest to reach this goal. These accomplishments have helped cultivate the field of medical ultras...

While there are no known risks associated with diagnostic ultrasound, uncertainty about the safety of prenatal ultrasound exposure remains. The purpose of the present experiment was to evaluate the behavioral teratogenic potential of continuous-wave (cw) ultrasound in rats, in the absence of maternal anesthesia or restraint. Pregnant CD rats, trained to remain immobile in a water-filled ultraso...
