PURPOSE: The aim of this study was to compare the ultrasonographic findings of femoral puncture sites and the complications of Perclose ProGlide® and FemoSeal™ after neurointerventional procedures. METHODS: In this prospective, single-center study, we randomly assigned 155 femoral puncture sites to treatment with Perclose ProGlide® or FemoSeal™. We hypothesized that the two different types of VCD cause different vascular changes. Ultrasonography of the femoral puncture sites was performed 24 h after the procedure and at an outpatient visit after 6 months...

BACKGROUND AND OBJECTIVE: Congenital anomalies are seen at 1-3% of the population, probabilities of which are tried to be found out primarily through double, triple and quad tests during pregnancy. Also, ultrasonographical evaluations of fetuses enhance detecting and defining these abnormalities. About 60-70% of the anomalies can be diagnosed via ultrasonography, while the remaining 30-40% can be diagnosed after childbirth. Medical diagnosis and prediction is a topic that is closely related with e-Health and machine learning...

BACKGROUND: Renal transplantation can significantly improve the quality of life of patients with end stage renal disease (ESRD) who would otherwise require dialysis. Renal transplant (RT) recipients have higher risks of cardiovascular disease compared with general population. The carotid intima-media thickness (CIMT) and pulse wave velocity (PWV) have been used as the important predicting factor of vascular arteriosclerosis. Therefore, this study was to investigate the improvement of carotid intima-media thickness and pulse wave velocity in renal transplant recipients...

BACKGROUND: Over 50% of newly diagnosed thyroid nodules are either cytologically benign or presumed to be benign on the basis of low-suspicion sonographic findings. The strategies used for their long-term surveillance are based mainly on the estimated residual risk of malignancy calculated with various ultrasonographic classification systems (e.g., Thyroid Image Reporting and Data Systems [TIRADS]). We conducted a longitudinal study to evaluate the temporal stability of the initial risk estimates computed with five widely used systems and to determine whether risk-class increases during follow-up are indeed predictive of malignancy...

The purpose of this study was to evaluate the clinical characteristics of 44 pediatric patients who were diagnosed as having nutcracker syndrome (NCS). We also investigated the left renal vein Doppler ultrasonography (DUS) results, to determine whether or not there was an association between clinical symptoms and DUS findings among these patients. The clinical data from 44 pediatric patients who were diagnosed as having NCS from January 2008 to December 2015 were retrospectively reviewed. We grouped the patients according to the presenting symptoms as symptomatic (loin pain; macroscopic hematuria or both) and non-symptomatic (microscopic hematuria and proteinuria were detected incidentally) and evaluated the left renal vein DUS indices in these two groups separately...

OBJECTIVES: Ultrasonography (US) has been considered to have a more limited role in the diagnosis of pyriform sinus fistulas than computed tomography. The aim of this study was to evaluate the US characteristics of pyriform sinus fistulas involving the thyroid gland in an attempt to improve our ability to diagnose this condition using US. METHODS: Between 2005 and 2016, 14 patients with pyriform sinus fistulas presenting as suppurative thyroiditis or as thyroid nodules were enrolled in the study...

Background: Thyroid nodules are a common finding, especially in iodine-deficient regions. Ultrasonographic scoring systems such as Thyroid Imaging Reporting And Data System (TIRADS) are helpful in differentiating between benign and malignant thyroid nodules by offering a risk stratification model. Depending on the constellation or number of suspicious ultrasound features, a fine needle biopsy (FNB) is recommended. However, none of the previously published TIRADS considered the functional status of the nodules...

BACKGROUND: Vesicoamniotic shunting (VAS) and other bladder drainage techniques for fetal lower urinary tract obstruction (LUTO) have been proven to ameliorate pulmonary hypoplasia and increase survival in patients with an initial poor prognosis. Currently there are limited prognostic tools available during gestation to evaluate and predict postnatal renal function. OBJECTIVE: The aim was to describe the prenatal growth of the renal parenchymal area (RPA) in patients with LUTO and determine its application as a predictor of renal function at one year of life...

Thyroid and salivary gland are amongst the most common sites subjected to fine needle aspiration cytology (FNAC) due to easy accessibility of these sites along with high diagnostic accuracy of FNAC. The performance of FNAC can be increased with the use of ultrasonographic guidance and rapid on-site evaluation. Cell block along with immunochemistry and other ancillary techniques further helps in clinching the correct diagnosis in certain diagnostically challenging cases. Core needle biopsy (CNB) is proposed to have a better diagnostic accuracy in certain situations...

BACKGROUND: Individuals with anterior cruciate ligament reconstruction (ACLR) are at greater risk for knee osteoarthritis, which may be in part due to altered gait biomechanics. Articular cartilage thickness is typically imaged using magnetic resonance imaging, which is costly and lacks portability. Ultrasonography may provide an alternative imaging method for articular cartilage. It is unclear if ultrasonographic measurements of cartilage thickness are associated with gait biomechanics in individuals with ACLR...

Proficiency in echocardiography and lung ultrasound has become essential for anesthesiologists and critical care physicians. Nonetheless, comprehensive echocardiography measurements often are time-consuming and technically challenging, and conventional 2-dimensional images do not permit evaluation of specific conditions (eg, systolic anterior motion of the mitral valve, pneumothorax), which have important clinical implications in the perioperative setting. M-mode (motion-based) ultrasonographic imaging, however, provides the most reliable temporal resolution in ultrasonography...
