OBJECTIVES: To assess intraexaminer and interexaminer reliability of 3-dimensional fetal sonographic measurements. METHODS: Three-dimensional fetal organ volumes (head, kidney, total thigh volume, and fractional thigh volume) were acquired during the second and third trimesters, with the addition of placental volume in the second trimester, by 2 different experienced, blinded sonographers. Fifty-eight fetuses were examined from 21 to 39 weeks' gestation. Intraexaminer and Interexaminer reliability was assessed with Bland-Altman plots, and their 95% limits of agreement and intraclass correlation coefficients...

BACKGROUND: Diagnosis of elbow fracture can sometimes be difficult with plain radiography due to overlapping bones, growth plates, and maturing bones in the pediatric population. The radiographic posterior fat pad (PFP) sign is one of the frequently referenced indirect signs of an occult elbow fracture. This sign can be falsely negative if the sign is subtle, and can be falsely positive when the position of the elbow is not flexed at 90 degrees. CASE REPORT: We discuss a case in which sonographic PFP sign helped to diagnose an elbow fracture...

Ultrasound reports of 102 children with microbiologically confirmed or clinically diagnosed pulmonary tuberculosis (TB) showed that 23/37 (64%) and 23/65 (36%) had TB suggestive abdominal lymphadenopathy and 16/37 (44%) and 8/65(13%) had splenic micro-abscesses, respectively. Splenic micro-abscesses were associated with HIV-infection (p=0.041). These data suggest that pulmonary TB is often complicated by abdominal TB in children.

Uterine fibroids are the most common neoplasm of the genital tract in reproductive women. Obesity holds a role as risk factor for uterine fibroids, through hormonal and inflammatory mechanisms. Visceral fat is a hormonally active tissue, so an increase in visceral fat may be considered as a risk factor, through the increased production of inflammatory mediators. The aim of the study was, therefore, to evaluate the association between the presence of uterine fibroids and fat tissue distribution, and to assess the efficacy of both anthropometric and instrumental indicators, in particular the sonographic measurement of preperitoneal fat thickness (PFT) and subcutaneous fat thickness (SFT)...

We reclassified 179 cases of the follicular variant (FV) of papillary thyroid carcinoma (PTC) into 72 (40.2%) noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), 37 (20.7%) encapsulated FVPTC with invasion (EFVPTC), and 70 (39.1%) infiltrative FVPTC (IFVPTC) without a capsule. In the NIFTP group, 5.6% cytology were hypercellular and the remainder low to moderate cellularity. PTC nuclei were absent in 18%, focally present in 37.5%, and diffusely present in 44.4%. In the EFVPTC group, 8...

Pediatric lumbar puncture can be challenging or unsuccessful for several reasons. At the same time, the excellent sonographic window into the pediatric spine provides a distinct opportunity for ultrasound-guided lumbar puncture. Minimal cerebrospinal fluid and thecal displacement by subdural or epidural hematomas are common after failed clinical attempts. Ultrasound is useful for determining a safe infraconal level for subarachnoid access. Real-time guidance increases not only the success rate but also the safety of diagnostic lumbar puncture and injections for chemotherapy and myelography...

Introduction The placement of intramammary marker clips has proven to be helpful for tumor localization in patients undergoing neoadjuvant chemotherapy and breast-conserving surgery. The purpose of our study was to investigate the feasibility of using a clip marker system for breast cancer localization and its influence on the imaging assessment of treatment responses after neoadjuvant chemotherapy. Patients and Methods Between March and June 2015, a total of 25 patients (n = 25), with a suspicion of invasive breast cancer with diameters of at least 2 cm (cT2), underwent preoperative sonographically guided core needle biopsy using a single-use breast biopsy system (HistoCore™) and intramammary clip marking using a directly adapted clip system based on the established O-Twist Marker™, before their scheduled preoperative neoadjuvant chemotherapy...

Axillary lymph node status remains an important prognostic factor in early breast cancer. It is regarded as an indicator for (neo)adjuvant systemic treatment and postoperative radiotherapy of the regional lymphatics. Commenced in September 2015, the INSEMA trial is investigating whether operative determination of nodal status as part of breast conserving therapy (BCT) for early stage breast cancer (c/iT1-2 c/iN0) can be avoided without reducing oncological safety. After inclusion of 1001 patients there was general acceptance of the complex study design by patients and study doctors so that recruitment for the first randomisation (axillary sentinel lymph node biopsy [SLNB]: yes or no) achieved predicted case numbers...

Siliconomas are subcutaneous nodules that usuallyappear as a consequence of the migration of freesilicon implanted in other locations. They are morefrequent in women with abnormal breast implants,such as poly implant prostheses (PIP), but they may alsoappear after illegal injection of free silicone. We reporta 57-year-old woman who attended our Dermatologyclinic complaining of relapsing facial panniculitis ofunknown origin. After a thorough work-up, thesenodules were determined to be the consequence ofdermal filler made with fluid silicone, which had beeninjected 20 years prior...

BACKGROUND: Safe management of the second stage of labor is of great importance. Unnecessary interventions should be avoided and correct timing of interventions focused. Ultrasound assessment of fetal position and station has a potential to improve the precision in diagnosing and managing prolonged or arrested labors. The decision to perform vacuum delivery is traditionally based on subjective assessment by digital vaginal examination and clinical expertise and there is currently no method of objectively quantifying the likelihood of successful delivery...

PURPOSE: The presence of anterolateral ligament of the knee is still controversial, and some physicians prefer to call this structure anterolateral complex (ALC) to infer plural nature of structures involved. The purpose of this study was to describe the scanning techniques and to classify various sonographic appearances of the tibial-side ALC of the knee in subjects with anterior cruciate ligament (ACL) injury. It was hypothesized that sonographic abnormity of the ALC would be associated with ACL injury history...
