Predictive Value of Abnormal Findings on Covered Transjugular Intrahepatic Portosystemic Shunt Baseline Doppler Sonography
Doppler ultrasound (DUS) is frequently performed as a screening and diagnostic modality to evaluate the transjugular intrahepatic portosystemic shunt (TIPS) for short- and intermediate-term complications of the procedure. However, the clinical significance of initial frequently observed abnormalities in flow velocities, gradient, and direction in patients with covered TIPS is less studied. A retrospective study was performed between January 2005 and December 2014, and all patients undergoing covered TIPS procedure for the management of portal hypertension were included. Abnormal DUS findings were defined as intrashunt peak...

Noninvasive Assessment of Liver Parenchyma Using Gray-Scale Ultrasound-Based Histogram Analysis in Patients With Chronic Hepatitis B Infection
The aims of this study were to examine the alterations of liver echo-intensity histogram parameters in chronic hepatitis B (CHB) patients and to assess the potential role of histogram parameters in the evaluation of hepatic fibrosis. A total of 52 patients with CHB who underwent liver biopsies were included in the study. The control group consisted of 30 healthy individuals. Histogram parameters were obtained from histogram analysis of gray-scale ultrasound images of both groups. The histogram parameters of the groups were compared. The association of histogram parameters with the grading and staging of histological activi...

Shear Wave Elastography Evaluation of Testes in Patients With Varicocele
We aimed to determine histological damage in patients with varicocele by comparing the elasticity of their affected testes with that of their normal contralateral testes as well as normal testes of control subjects without varicocele using shear wave elastography (SWE). In total, 48 patients with varicocele (96 testes) and 52 control subjects (104 testes) were included in this study. Shear wave elastography values were measured in the longitudinal plane using an oval region of interest that covered as much of the testicular contours as possible. Fifty testes with varicocele were classified as group A, 46 normal contralater...

Diaphragmatic Ultrasonography, a Novel Approach in Critical Care: A Proposal for a New Weaning Index
The evaluation of the diaphragm in critically ill patients is simple and noninvasive and has shown good repeatability. The aim of the study was to generate a predictive index for successful weaning (ULDIMex) from invasive mechanical ventilation (IMV) based on an ultrasonographic diaphragmatic assessment before performing a spontaneous breathing test. We recruited patients who required IMV and who were candidates for weaning from ventilation. The measurement of diaphragmatic excursion and time during inspiration and expiration was obtained with a 3- to 5-MHz probe in the M mode. Using the formula (a + b)c/2, the value for t...

The Ultrasound Anatomy of Nerves in the Interscalene Groove: Can We Reliably Distinguish the Nerve Structures for Needle Placement During Nerve Blocks?
In the interscalene groove, nerve structures are in close proximity and may not be visible as separate structures, increasing the risk of insertion of the needle tip within the epineurium. We evaluated whether experienced regional anesthesiologists can distinguish between nerve elements lying in close proximity on ultrasound images. Brachial plexus elements from 4 nonpreserved cadavers were arranged in a water bath. Ultrasound images of the nerve roots and trunks were taken. Regional anesthesiologists and residents were asked whether they could distinguish the nerves as 2 separate structures and if they could identify a p...

Renal Hemodynamic Changes and Postsurgical Recovery in Children Treated for Ureteropelvic Junction Obstruction
Conclusions Peak systolic velocity and RI were correlated with renal function and renal parenchymal thickness but were not correlated with dilatation of the renal pelvis. Peak systolic velocity increased whereas RI decreased after surgery and were stable at 8 weeks, but remained abnormal 16 weeks after surgery. Hemodynamic measurements may be a useful and convenient method to evaluate surgical outcomes after Anderson–Hynes pyeloplasty. (Source: Ultrasound Quarterly)

Thyroid Image Reporting and Data System Categorization: Effectiveness in Pediatric Thyroid Nodule Assessment
Ultrasonography (US) is the main imaging method to assess thyroid nodules. In the pediatric population, thyroid nodules are less prevalently seen than those in adults. However, approximately 25% of the nodules can be malignant. Validation of Thyroid Image Reporting and Data System (TI-RADS) classification has been mostly tested in adults, and information on pediatric cases is limited. In the current study, we aim to define the diagnostic power of the TI-RADS risk stratification method in pediatric thyroid nodules. The study population consists of 68 nodules of 64 patients (20 malignant, 48 benign). We have included patien...

Dynamic Compression—A New and Practical Technique for the Sonographic Diagnosis of Enteric Duplication
Conclusions The 5-layer sign and peristalsis were not sensitive for enteric duplication. The split-wall sign may have the highest sensitivity and specificity for enteric duplication, but finding this sign is technically difficult and interpretation is complicated by atypical variations. Dynamic compression differentiated enteric duplication from other abdominal cysts with 82% accuracy, and this technique was simple to perform and easier to interpret than the split-wall sign.

Hyperechoic Abdominal Fat: A Sentinel Sign of Inflammation
One of the most useful sonographic signs of acute abdominal inflammation is the identification of increased echogenicity of the surrounding fat. Hyperechoic fat results from vasodilation and edema extending from an adjacent source of infection or inflammation. These changes are mediated by such factors such as bradykinin, histamine, and various cytokines. The recognition of hyperechoic fat on sonography may be an important indicator of the primary source of pathology. In addition, it often reflects a more advanced degree of transmural pathology, such as “walled-off” perforation of a hollow viscus. This pictoria...
