AIM To determine if there are different penile hemodynamic patterns between sildenafil non-responders and responders by using color Doppler ultrasonography. METHODS A total of 69 erectile dysfunction (ED) patients aged 22-79 years were enrolled into the present study. Thirty-eight (55.1%) men with ED who did not respond to four attempts of treatment with 100 mg sildenafil after re-education w...

INTRODUCTION Ultrasonography and magnetic resonance imaging (MRI) are used to evaluate shoulder disorders. This implementation study investigated outpatient ultrasonography at an orthopedic practice in a managed care setting. METHODS A portable ultrasound machine was introduced at an orthopedic clinic in a group practice. An orthopedic surgeon who primarily treated shoulder disorders received...

— Various model parameter calculation equations of RF CMOS inductors are compared. The calculation equations are using as variables either Y, Z-parameters or S-parameters. Results are based on on-wafer RF S-parameter measurements of a 3.75 turn spiral inductor fabricated in AMIS 0.7 μm CMOS DM1P n-well technology. Results obtained with calculation equations for a differentially driven inductor ...

OBJECTIVE To investigate diagnostic value of ultrasonography scores (US) and contrast-enhanced ultrasonography (CEUS) in evaluating rheumatoid arthritis (RA) activity. METHODS 39 patients with RA were included and the metacarpophalangeal, proximal interphalangeal, wrist, elbow and knee joints of them were examined by high frequency ultrasound. The severe joints and the related indexes (synovi...

The debate regarding the efficacy of varicocele ligation for improvement of semen parameters and pregnancy rates is ongoing. In addition, no consensus exists as to the benefit of treatment of subclinical varicoceles. The aim of this study was to investigate, retrospectively, the effect of high ligation of both subclinical and clinical varicoceles on sperm count and motility. The value of severa...

The aim of this study was to evaluate the role of neck ultrasonography compared to (131)I whole-body scan (WBS) and circulating thyroglobulin (Tg) measurement after thyroid hormone withdrawal in the follow-up of children with thyroid papillary cancer, who had previously undergone total thyroidectomy for the diagnosis of neck lymph node metastases (LNM). Forty-five children were examined. Neck u...

Objective- to assess the normal ultrasonographic findings of kidney in the Raiini goat. Design- Experimental study. Animals- 10 female Raiini goats. Procedures- .Necropsy was carried out and Kidneys were measured in length, width, and diameter after fixation in formalin. Ultrasonography was carried out by longitudinal and transversal planes to evaluate all renal structures. Echogenicity and ...

abstract primary neuroendocrine carcinoma of the breast is a very rare malignant tumor. there are not many cases reported in the english literature since it was first documented in 1983. reports on the imaging features, in particular the ultrasonographic features of this rare tumor are scarce. herein, we report a case of aggressive primary infiltrating neuroendocrine carcinoma of the breast, ma...

introduction: correct interpretation of kidney images requires the knowledge of its normal size. this study aimed to establish normal values for kidney length and parenchymal thickness and identify the potential related factors in a group of iranian adults. methods: renal dimensions, including length and parenchymal thickness were measured by sonography in 103 individuals with no renal disease....
