Lung Ultrasonography as an Accurate Diagnostic Method for the Diagnosis of Community-Acquired Pneumonia in the Elderly Population
Community-acquired pneumonia (CAP) is one of the most common causes of both hospitalization and death in elderly patients. The chest x-ray (CXR) is nowadays still the imaging method of choice for patients suspected of having pneumonia. However, the sensitivity of CXR, particularly bedside chest radiography, is relatively low. Chest computed tomography, the procedure of higher precision, cannot be conducted routinely for safety, organizational, and economic reasons. Thus, lung ultrasonography (LUS) could be the most accurate diagnostic tool for CAP in the geriatric population. (Source: Ultrasound Quarterly)

Lung Ultrasound for the Diagnosis of Neonatal Respiratory Distress Syndrome: A Meta-analysis
Chest radiography is the primary imaging modality used for the assessment of neonatal respiratory distress syndrome (NRDS) in newborns. However, excessively exposing a growing neonate to harmful ionizing radiation may have long-term consequences. Some studies have shown that lung ultrasound (LUS) is helpful in the diagnosis of NRDS. A comprehensive search was carried out using PubMed, Embase, and the Cochrane Library to identify studies in which newborns with clinically suspected NRDS were assessed by LUS. Two investigators independently screened the literature and extracted the data. Any discrepancies were resolved via di...

Contrast-Enhanced Ultrasound-Guided Interventions—The New Sheriff in Town?: A Case-Based Review of Problem Solving With Ultrasound Contrast
Ultrasound (US)–guided intervention is a well-established medical procedure and offers advantages such as real-time guidance, portability, reduced cost, shortened procedure time compared with computed tomography, and lack of ionizing radiation. Ultrasound contrast agents (UCAs) are a useful adjunct to US-guided procedures. The addition of microbubble UCAs during US-guided interventions can assist with biopsy planning and lesion selection, aid in identification of target lesions, and direct the biopsy toward viable tissue. Ultrasound contrast agents have been in use outside of the United States for many years and have bee...

Relationship Between Shear Wave Elastography Findings and Histologic Prognostic Factors of Invasive Breast Cancer
Conclusions
We found that some clinicohistopathologic features of poor prognosis had higher elasticity values than those of favorable prognosis. (Source: Ultrasound Quarterly)

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...

Application of Contrast-Enhanced Sonography on the Diagnosis of Acute and Chronic Rejection After Renal Transplantation
To test the reliability of CEUS on the diagnosis of acute (AR) or chronic rejection (CR) after renal transplantation, patients who received renal transplantation in our center from January 2011 and December 2015 were retrospectively included in the current study. All the included patients underwent contrast-enhanced ultrasonography tests. Two regions of interests were chosen to carry out time-intensity curves (TICs). The main indexes include time indexes, intensity indexes, and difference indexes. Separation of TIC1 and TIC2 was evaluated by the authors. Results revealed that time to peak 1 (TTP-1), TTP-2, absolute time to...

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...

Should We Perform Transthoracic Trucut Lung Biopsies of Pleural-Based Lung Masses Under Ultrasound Guidance or Computed Tomography Guidance?
We aimed to emphasize which method should be prioritized by comparing the ultrasound and computed tomography (CT) guidance for percutaneous transthoracic biopsy of pleural-based lung lesions in terms of comorbidity, diagnostic success, time, and costs.
Approximately 700 biopsy procedures performed between 2014 and 2018 were retrospectively reviewed. The files of these patients and picture archiving and communication system were scanned.
Size and localization of the lesion, pathological diagnosis, comorbidity status, pneumothorax complications at the end of the procedure, and whether or not a thoracic tube was placed due ...

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...
