PURPOSE To develop a computer-aided diagnosis (CAD) algorithm with setting-independent features and artificial neural networks to differentiate benign from malignant breast lesions. MATERIALS AND METHODS Two sets of breast sonograms were evaluated. The first set contained 160 lesions and was stored directly on the magnetic optic disks from the(More)
The purpose of this study was to evaluate the morphologic changes in the ulnar nerve in cubital tunnel syndrome with high-resolution ultrasonography. The mean values of the short axis (cm) x long axis (cm) at the arm, epicondyle, and forearm levels were 0.057 +/- 0.01, 0.068 +/- 0.019, and 0.062 +/- 0.01 in control group; 0.069 +/- 0.04, 0.139 +/- 0.06, and(More)
The peripheral nerve is demonstrated as a reticular pattern in a transverse section at high-resolution ultrasonography (US). Its echogenicity is between that of tendon and muscle. High-resolution US applied to lesions of peripheral nerves yields impressive results in that the nerve is highly differentiated from surrounding soft tissue. In cases of trauma,(More)
BACKGROUND To describe the prevalence and sonographic findings and ultrasound diagnostic accuracy of the right side colonic diverticulitis in patients having right lower abdominal pain with indeterminate nature. METHODS A total of 934 patients with acute right lower abdominal pain of clinically indeterminate nature were referred for ultrasound examination(More)
Five osteosarcoma (OS) cell lines, 37 OS tumors and 9 corresponding non-neoplastic samples were genotyped by Affymetrix 10 K 2.0 SNP array. Regions of high level amplification and homozygous deletion were identified and validated by quantitative PCR and FISH. Certain recurrent cytogenetic alterations were more frequent in recurrent/metastatic than in(More)
Percutaneous renal biopsy is frequently performed, and postbiopsy arteriovenous fistula (AVF) formation is not uncommon. In most cases, it is asymptomatic and remains undiagnosed, because Doppler examination is not performed routinely. We describe 2 cases of postbiopsy AVF of the kidney that were detected 61 and 17 months after renal biopsy, respectively.(More)
PURPOSE To determine the incidence of testicular microlithiasis (TM) in Taiwanese males who were referred for scrotal sonography (US) and to evaluate the association between TM and cancer, with state-of-the-art equipment. METHODS This retrospective study included 513 males who underwent scrotal US in a period of 7 months. The US images and charts of each(More)
OBJECTIVES To evaluate the therapeutic effect of extracorporeal shock wave therapy (ESWT) in shoulders with chronic calcific tendinitis, to compare the functional outcomes of ESWT and transcutaneous electric nerve stimulation (TENS) therapy, and to investigate which types of calcium deposit effectively respond to ESWT. DESIGN Randomized controlled trial.(More)
PURPOSE To evaluate the peritendinous lesions over the extremities by high-resolution ultrasonography (HRUS). MATERIALS AND METHODS The authors retrospectively collected 328 cases, focusing on peritendinous lesions in limbs. The diagnosis was made by US findings with long-term follow-up, aspiration and biopsy proved. RESULTS The most common disease(More)
OBJECTIVE The purpose of this study was to evaluate the appearance of primary peripheral soft tissue lymphoma on high-resolution ultrasonography. METHODS We retrospectively studied the sonograms of 12 patients (5 female and 7 male; age range, 12-90 years; mean, 55 years) with soft tissue lymphoma. All lesions were palpable and in the salivary glands,(More)
