PURPOSE: To investigate the imaging features of cyst infection in autosomal dominant polycystic kidney disease (ADPKD) patients using computed tomography (CT) and ultrasonography (US). MATERIALS & METHODS: The institutional review board approved this retrospective study. Fifty-one episodes with proven cyst infection in forty-three ADPKD patients were included. Two experienced abdominal radiologists reviewed CT and US images and evaluated the following imaging features in consensus: cyst size, location, cyst shape, intracystic attenuation, intracystic echogenicity, intracystic heterogeneity, wall thickness, the presence of fluid-fluid level, septation, intracystic gas, pericystic fat infiltration, and pericystic hyperemia...

BACKGROUND: Axillary venous access with ultrasound guidance for pediatric transvenous lead implantation may reduce risks for pneumothorax and hemothorax. The objective was to retrospectively evaluate ultrasound-guided axillary vein access as an alternative to the subclavian approach. METHODS: The technique consists of ultrasonographic identification of the axillary vein at the delto-pectoral groove after initial contrast venography. A micropuncture kit is used for initial ultrasound-guided percutaneous access with fluoroscopic confirmation of wire position...

Aggressive angiomyxoma (AAM) is a rare tumour that often occurs in soft tissues of the female genital tract. Eight cases of AAM are reported in this article, and the clinical features and ultrasound and magnetic resonance imaging (MRI) results of the eight cases are reviewed and summarized. The main complaints of all the patients were palpable and painless masses in the vulva or scrotum. The lesions were mainly located in the vulva, pelvis, and perineal region, with a large scope of involvement. The sonographic features of AAM were characteristic...

REVIEW
Per Hedenström, Riadh Sadik
Endosonography (EUS) has an estimated long learning curve including the acquisition of both technical and cognitive skills. Trainees in EUS must learn to master intraprocedural steps such as echoendoscope handling and ultrasonographic imaging with the interpretation of normal anatomy and any pathology. In addition, there is a need to understand the periprocedural parts of the EUS-examination such as the indications and contraindications for EUS and potential adverse events that could occur post-EUS. However, the learning process and progress vary widely among endosonographers in training...

Purpose: The aim of this study was to evaluate whether the comet tail artifact on ultrasonography can be used to reliably diagnose benign gallbladder diseases. Methods: This retrospective study reviewed the clinical findings, imaging findings, preoperative ultrasonographic diagnoses, and pathological diagnoses of 150 patients with comet tail artifacts who underwent laparoscopic cholecystectomy with pathologic confirmation. The extent of the involved lesion was classified as localized or diffuse, depending on the degree of involvement and the anatomical section of the gallbladder that was involved...

OBJECTIVE: Data concerning feasibility of the fetal cerebral Doppler examination in full term and late term pregnancy is lacking. Our purpose was to perform an evaluation of these arteries with power Doppler ultrasound, calculating the percentage of identification and measurement and the intraobserver reproducibility. METHODS: This was a cross sectional study evaluating a population of 578 normally grown fetuses divided according to the week of examination. The first group included fetuses examined at week 40 (N = 323) and the second fetuses examined at week 41 (N = 255)...

The aim of this study was to compare uterine two-dimensional and Doppler ultrasonographic parameters in queens suffering from pyometra from those in early pregnancy. Secondly, the effect of the presence of clinical signs of systemic illness on these parameters was also described. Fourteen post-oestrous queens, with uterine luminal content in the absence of embryos were included. According to their outcome (pyometra surgery or parturition), the queens were retrospectively assigned to one of the following groups: Pyometra (PYO; n = 7) or pregnant (PRG; n = 7)...

The aim of this study was to evaluate two-dimensional and Doppler ultrasonographic changes of feline ovaries before and during puberty. Nine, 3-month-old female cats were followed until puberty (Day 1). Two-dimensional and Doppler ultrasound evaluations of the ovaries were carried out on Days -50, -20, -7 and 1. Longitudinal and transverse sections of the ovaries were measured and all anechoic spherical structures were considered to be follicles. The number of follicles >1 mm and the maximum diameter of the largest follicle were recorded...

Hypotension in patients under general anesthesia is prevalent and causes unfavorable outcomes. Carotid intima-media thickness (CIMT) is a surrogate marker for atherosclerosis and useful for evaluating the risk of cardiovascular diseases. We investigated the usefulness of preoperative CIMT measurement as a predictor of post-induction hypotension (PIH). The ultrasonographic measurement of CIMT was performed preoperatively on 82 patients scheduled for elective surgery under general anesthesia in a prospective, observational study...

We described fecal retention during the defecation cycles of adults with functional constipation via ultrasonography (US) of the large intestine. US was performed continuously after the last defecation until the next defecation. We defined the fecal finding level on US as follows: weak fecal retention, a marginally high echo in the colonic lumen; or strong fecal retention, a strongly echoic colon lumen with showing a crescent-shaped acoustic shadow on transverse images and haustrations on longitudinal images...

The aim of this study was to explore changes in the common carotid arterial wall elasticity after smoking cessation. Carotid artery ultrasonographic examination was performed in 136 patients, then 1 or 2 years after smoking cessation. We used echo-tracking (ET) to measure stiffness index (β), pressure-strain elasticity modulus (Ep), arterial compliance (AC), augmentation index (AI), and local pulse wave velocity (PWVβ). Patients were divided into four groups based on whether or not they successfully stopped smoking (groups M and N, respectively) and whether (groups M2 and N2, respectively) or not (groups M1 and N1, respectively) they showed comorbidities...

Cesarean sections account for approximately 20% of all deliveries worldwide. In Poland, the percentage of women delivering by cesarean section amounts to over 43%. According to studies, the prevalence of cesarean scar defects ranges from 24-70%. Due to the overall cesarean section rate, this is a medical problem affecting a large population of women. In such cases, ultrasonographic evaluation of a cesarean scar reveals a hypoechoic space filled with postmenstrual blood, representing a myometrial tear at the wound site...

Background The triangular cord (TC) sign is the appearance of a triangular shaped echogenic density visualised immediately cranial to the portal vein bifurcation on ultrasonographic examination. Several studies have reported that this ultrasonographic sign is a reliable and helpful marker in identifying Biliary Atresia (BA).

Previous studies have compared the effectiveness of dinoprost and cloprostenol in cows yielding conflicting results. The aim of our study was to evaluate the efficacy of single treatment with cloprostenol or dinoprost on estrus and reproductive performance in cows with unobserved estrus after service. The study was conducted over four years in two dairy herds of Polish Holstein Frisian cows under a herd health program with an average milk yield per cow over 9000 L. Cows (n=523) diagnosed ultrasonographically as non-pregnant and with a corpus luteum were randomly assigned to be treated with either cloprostenol (n=261) or dinoprost (n=262)...
