Contrast enhancement by microbubble infusion has proven its applicability in the field of diagnostic ultrasound. Recent studies also indicate a therapeutic effect of the combined use of ultrasound and microbubbles. Results from animal studies demonstrate that diagnostic ultrasound in combination with intravenous microbubbles can dissolve thrombi. So far, this effect has never been tested in pat...

hydatid cyst (hc) is a parasitic disease that may involve many organs, especially the lung and the liver. pulmonary artery location of the hydatid cyst is extremely rare, but it may cause life-threatening complications. we report a case of a hydatid cyst that completely filled the left main pulmonary artery and its distal part without cardiac involvement. thoracic computed tomography showed fil...

Human lymphocyte cultures were examined for chromosome damage after exposure to ultrasound. Control and treated slides were scored "blind" and showed no evidence of damage due to ultrasound. Neither was there evidence of chromosome damage in blood cultures from six infants whose mothers had ultrasound during pregnancy when compared with that from six infants whose mothers had not. Our results s...

This article discusses the benefits of integrating point-of-care diagnostic ultrasound into the four-year medical school curriculum. Handheld ultrasound devices have been used to teach medical students at the University of California (UC), Irvine, since August 2010, and the article explains how the use of this inexpensive, safe, and noninvasive tool enhances the ability of a physician conductin...

OBJECTIVES Utilization of ultrasound in the evaluation of patients with undifferentiated hypotension has been proposed in several protocols. We sought to assess the impact of an ultrasound hypotension protocol on physicians' diagnostic certainty, diagnostic ability, and treatment and resource utilization. DESIGN Prospective observational study. SETTING Emergency department in a single, acad...

BACKGROUND Survey data over the last several decades suggests that emergency department (ED) access to diagnostic ultrasound performed by the radiology department is unreliable, particularly outside of regular business hours. OBJECTIVE To evaluate the association between the time of day of patient presentation and the use of diagnostic ultrasound services in United States (U.S.) EDs. METHOD...

Background: Mature cystic teratoma of the ovary is one of the most common benign ovarian tumors, which may be confused with other adnexal lesions due to its extensive manifestations on ultrasound. Therefore, in this study, we tried to reduce the need for pathology frozen sections by examining more accurate preoperative ultrasound results and classifying ovarian lesions based on them. Methods: ...

The title of this book is misleading since the subject matter is not diagnostic ultrasound as a clinical entity but rather the basic biological effects of ultrasound, and possible hazards involved in the diagnostic use of this modality. Within this limitation, it is an extremely useful volume which will find wide application as a basic but small reference work for clinical ultrasound. A chapter...
