because of superficial location and not being covered by boney structure, thyroid is the ideal organ for 2-dimensional gray scale ultrasonography. availability of relatively low cost equipment and ever increasing number of endocrinologists with expertise in thyroid ultrasound has made it an integral part of thyroid practice in the office of endocrinologists. in particular, the current recommend...

It has been just five years since gray-scale ultrasound (U/S) became clinically available. Yet the day-to-day importance of U/S in general medicine and surgerynot just the traditional areas of ob/gyn and echocardiography-would be hard to overestimate. Because U/S is so new, however, there are still many clinicians who are ill at ease with those funny fuzzy speckled images, so different from the...

the pathological scrotum Conventional high resolution gray-scale ultrasonography is excellent at evaluating scrotal pathology. The particular value of gray-scale ultrasonography is that it may distinguish between intra-testicular and extra-testicular pathology with 90 -99% accuracy (Krone and Carroll, 1985; Narayan et al., 1981). This distinction is of importance as the majority of intra-testic...

This study was conducted to retrospectively evaluate the pattern of contrast enhancement with SonoVue on gray-scale ultrasonography of hepatic angiomyolipoma (HAML). Imaging features of 33 pathologically proven HAML lesions in 33 patients who underwent baseline ultrasound and contrast-enhanced ultrasonography (CEUS) were assessed retrospectively. All lesions were enhanced in the arterial phase ...

OBJECTIVES Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after microbubble contrast injection) add informa...

OBJECTIVE The role of Doppler ultrasonography in the diagnosis of diffuse thyroid diseases is not well established. In particular, Doppler ultrasonography findings in children with Hashimoto's thyroiditis are very limited. We examined gray-scale and Doppler ultrasound findings in Hashimoto's thyroiditis in children in an attempt to understand the feasibility of future prospective controlled stu...
