Objective: To investigate the diagnostic accuracy of electrical impedance tomography (EIT) for benign and malignant breast diseases incomparison to conventional ultrasonography and mammography. Methods: A total of 121 patients with 126 breast lesions who underwent mammography ultrasonography and EIT were enrolled in the study. All of these lessions were were confirmed by pathological biopsy. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of EIT, ultrasonography and mammography were calculated with histology as the gold standard...

Ankle disorders are a relatively common pathological condition, and ankle injuries account for Epub ahead of print approximately 14% of sports-related orthopedic emergency visits. Various imaging modalities can be used to make a diagnosis in cases of ankle pain; however, ultrasound (US) has several benefits for the evaluation of ankle pain, especially in the tendons, ligaments, and nerves of the ankle. The purpose of this article is to review the common causes of ankle pathology, with particular reference to US features...

To investigate the safety of focused ultrasound (FUS) partial ablation on the pancreas of Sprague Dawley® (SD) rats by histopathological examination of the outcome and investigation of glycometabolism function changes after local ablation. A total of 135 healthy SD rats were randomly divided into three groups (n=45 of each): FUS ½ group, FUS ¼ group, and control group. Levels of serum amylase was measured using the enzyme dynamics method, fasting blood glucose was measured by the glucose oxidase-peroxidase method, fasting serum insulin was measured by direct chemiluminescence assay, and an ELISA was used to measure fasting serum glucagon immediately after treatment, and at 2h, 3days, 1, 2, 3 and 4weeks, 3 and 6months after FUS ablation...

Importance: Emergency department visits for skin infections in the United States have increased with the emergence of methicillin-resistant Staphylococcus aureus (MRSA). For cellulitis without purulent drainage, β-hemolytic streptococci are presumed to be the predominant pathogens. It is unknown if antimicrobial regimens possessing in vitro MRSA activity provide improved outcomes compared with treatments lacking MRSA activity. Objective: To determine whether cephalexin plus trimethoprim-sulfamethoxazole yields a higher clinical cure rate of uncomplicated cellulitis than cephalexin alone...

An 8 yr old neutered male springer spaniel dog was referred to Texas A&M University, College of Veterinary Medicine for a large, firm, fixed mass, located in the dorsal cervical tissue. The dog was otherwise healthy and had undergone microchip implantation approximately 8 yr prior. Radiographs, ultrasound, and microchip scanner confirmed the presence of a microchip within the mass. The microchip and associated mass were surgically excised, and histopathologic examination revealed granulomatous inflammation surrounding a cracked microchip...

Ultrasound imaging has become a prevalent examination method in prenatal diagnosis. Accurate acquisition of fetal facial standard plane (FFSP) is the most important precondition for subsequent diagnosis and measurement. In the past few years, considerable effort has been devoted to FFSP recognition using various hand-crafted features, but the recognition performance is still unsatisfactory due to the high intra-class variation of FFSPs and the high degree of visual similarity between FFSPs and other non-FFSPs...

In ultrasound image analysis, speckle tracking methods are widely applied to study the elasticity of body tissue. However, "feature-motion decorrelation" still remains as a challenge for speckle tracking methods. Recently, a coupled filtering method and an affine warping method were proposed to accurately estimate strain values when the tissue deformation is large. The major drawback of these methods is the high computational complexity. Even the GPU-based program requires a long time to finish the analysis...

Accurate lateral displacement and strain estimat- ion is critical for some applications of elasticity imaging. Typically, motion estimation in the lateral direction is challenging because of low sampling frequency and lack of phase information in conventional ultrasound imaging. Several approaches have been proposed to improve the performance of lateral estimation, such as lateral interpolation on the RF signals (Interp_RF), lateral interpolation on the cross-correlation function (Interp_CCF) and lateral interpolation on both the RF signals and cross-correlation function (Interp_Both)...

BACKGROUND: Sarcoidosis and tuberculosis (TB) share epidemiological, immunological, and molecular features common to both, and often, it becomes difficult to differentiate them especially in a highly TB-endemic country like India. We report a case of optic disc granuloma along with epididymitis and infertility in a male who showed a response to treatment with anti-tuberculosis therapy and steroids. RESULTS: A 35-year-old Indian male who presented with complaints of blurring vision in the right eye for 6 months and treated elsewhere with two intravitreal injections of anti-VEGF was found to have optic disc granuloma in the right eye...

Different genetic variants in estrogen receptor alpha (ESR1) have been shown to influence bone phenotypes including quantitative bone ultrasound in elderly. We aimed to investigate the role of ESR1 polymorphisms in bone mass assessed by calcaneal quantitative ultrasound (QUS) in a population of young adults. The study sample consisted of 466 healthy individuals of Caucasian ancestry (315 females and 152 males) aged 18 and 25 years (median age 20.39 ± 2.70). Six ESR1 polymorphisms (rs302033, rs2982552, rs2982575, rs2504063, rs2234693-PvuII and rs9340799-XbaI) were selected as genetic markers and genotyped...

A 30-year-old woman experienced severe abdominal pain 8 days after vaginal delivery. The patient was diagnosed with hemoperitoneum due to rupture of the left uterine artery pseudoaneurysm, which was confirmed via ultrasound with color Doppler and computed tomography scans. This patient was treated with bilateral uterine artery embolization to maintain fertility. A uterine artery pseudoaneurysm that causes delayed postpartum hemorrhage can occur after cesarean section or vaginal delivery. A uterine artery pseudoaneurysm can be fatal, so its detection and diagnosis are critical...

Inherently, brachytherapy is the most conformal radiotherapeutic technique. As an aid to brachytherapy, ultrasonography (USG) serves as a portable, inexpensive, and simple to use method allowing for accurate, reproducible, and adaptive treatments. Some newer brachytherapy planning systems have incorporated USG as the sole imaging modality. Ultrasonography has been successfully used to place applicator and dose planning for prostate, cervix, and anal canal cancers. It can guide placement of brachytherapy catheters for all other sites like breast, skin, and head and neck cancers...

[Purpose] The purpose of this study was to examine the reliability of ultrasound measurements by analyzing the relative reliability and absolute reliability when measuring soft tissue thickness around the shoulder joint. [Subjects and Methods] Eleven healthy young adults (22 shoulders) participated in this study. Thickness of the supraspinatus tendon, subacromial bursa, and biceps tendon was measured on both shoulders. This protocol was performed twice in the same day. The relative reliability of ultrasound measurement was evaluated using the intraclass correlation coefficient for determining the degree of consistency and agreement between two measures...
