BACKGROUND The use of therapeutic ultrasound as a contraceptive approach has involved nonhuman primates as well as rats and dogs. The current study was undertaken to determine whether this treatment could be a method for reversible contraception, using a model with testes size similar to adult humans. METHODS Two methods of ultrasound exposure were used, either the transducer probe at the bot...

Ultrasound examinations were done to evaluate clinically palpable abdominal masses in 125 children. The examinations were normal in 21 patients. In 15 patients, the clinically palpable masses were actually anterior abdominal wall abscesses or hematomas. Final diagnosis was available in 87 of 89 patients with intraabdominal masses detected on ultrasound. The majority (71%) were retroperitoneal m...

, Abstract—Background: Bedside ultrasound in the emergency department is being used with increasing frequency and for an increasing scope of conditions. Objectives: Demonstrate the use of bedside ultrasound as an adjunct for diagnosis of hip dislocation. Case Report: A traumatic anterior hip dislocation was diagnosed with bedside ultrasound after an initial normal plain radiograph. Conclusion: ...

PURPOSE The reliability and objectivity of computer assisted transrectal ultrasound are examined. MATERIALS AND METHODS Pathological examination of radical prostatectomy specimens was compared prospectively to automated cancer detection in corresponding transrectal ultrasound images. RESULTS For automated cancer detection, a sensitivity of 0.75 and a specificity of 0.78 were obtained. Moreo...

Parathyroid carcinoma (PC) is a rare endocrine malignancy. The tumor is mostly functioning, causing severe primary hyperparathyroidism, with high serum calcium and parathyroid hormone (PTH) levels. Nonfunctioning PC is extremely rare. We report a 50-year-old male patient who was referred to our Department for a right thyroid nodule, incidentally detected on carotid Doppler ultrasound scan, with...

OBJECTIVES This study was designed to assess the extent and timing of vasodilation after intracoronary administration of nitroglycerin using intravascular ultrasound. We also sought to relate the magnitude of nitroglycerin-induced dilation to the distribution of atherosclerotic plaque. BACKGROUND Although previous angiographic studies have shown that nitroglycerin can dilate both normal and s...

Herein, the concept and data for cancer treatment that combines ultrasound and nanoparticles is reported. Non-toxic gold and magnetic nanoparticles were used to enhance the ultrasound destruction of cancer cells in vitro. Separate monolayers of normal and cancer cells were treated by focused ultrasound with the result of more pronounced damage of cancer cells when biocompatible gold and magneti...

Ultrasound imaging has been used extensively to detect abnormalities of the non-lactating breast. In contrast, the use of ultrasound for the investigation of pathology of the lactating breast is limited. Recent studies have re-examined the anatomy of the lactating breast highlighting features unique to this phase of breast development. These features should be taken into consideration along wit...
