Interpreting neonatal hip sonography: intraobserver and interobserver variability

The purpose of this study is to state the reliability of neonatal hip ultrasound interpretation, defining the intra and interoperator variability in the evaluation of the scans. We considered a sample of 2071 scans (coming from 798 patients who attended the screening programme for hip dysplasia), which were interpreted by the operator who obtained and read the images at the screening time and then by a different operator who saw the images for the first time. Both the intra and interoperator variability of α and β angles’ values resulted statistically not significative (intraclass correlation coefficient> 0.8) and determining a class shift (according to the Graf’s classification) in a nonstatistically significative number of cases (agreement percentage>91% and Cohen’s κ>0.8). Hip sonography can reliably detect hip dysplasia and the intra and interoperator variability in the interpretation of the exam is NS when the examination is correctly executed.

This study aimed to investigate how a unilateral high-grade tear caused overdistension of LAM and whether tear positions affect the degree of distension. Methods A total of 209 women were screened by translabial ultrasonography. Then, 18 nulliparous women with an intact LAM and 26 postpartum women with unilateral levator ani defects were recruited. The anteroposterior diameter (AP), coronal diameter (LR), and hiatal area (HA) of the minimum levator hiatus were recorded and compared for assessing the distensibility. All 44 subjects underwent magnetic resonance imaging for the diagnosis of levator ani defect and detection...

Ultrasound (US) imaging systems typically employ a single beamforming scheme which is the delay and sum (DAS) beamforming due to its reduced complexity. However, DAS results in images with limited resolution and contrast. The limitations of DAS have been overcome by, delay multiply and sum (DMAS) beamforming, making it especially preferable in cases where finer image details are required in larger depth of scans for an accurate diagnosis. But, DMAS is confined to transducer frequencies where the generated harmonics also fall in the processable frequency range of the US system. However, if US systems could provide the flexi...

AbstractFelty ’s syndrome (FS) is a deforming disease, characterized by the triad of rheumatoid arthritis (RA), neutropenia, and splenomegaly. Currently, FS patients are treated mainly with immunosuppressants, such as methotrexate and glucocorticoids, which however are not suitable to some patients and may caus e severe side effects. Here we report a clinical FS case that was treated with Tocilizumab (TCZ) successfully. The patient had symmetrical swelling and pain of multiple joints, deformity of elbow joints with obvious morning stiffness. Joint color Doppler ultrasound showed synovial hyperplasia and bo ne erosion...

Conclusion: Choroidal ganglioneuroma is rare. To our knowledge, no bilateral cases have been described in the literature. Major clinical features include a rapid increase in axial length, diffuse choroidal thickening, hyper-reflectivity in the choroid on optical coherence tomography, and loss of choroidal vasculature on ICGA. The current report provides multimodal imaging of choroidal ganglioneuroma for the first time and can be valuable for early diagnosis. PMID: 32454990 [PubMed]

Abstract OBJECTIVES: To compare the efficacy of contrast-enhanced ultrasound enabled reclassification of Breast Imaging Reporting and Data System (CEUS-BI-RADS) with magnetic resonance imaging (MRI) in the diagnosis of breast lesions with calcification. METHODS: A total of 52 breast lesions with calcification from 51 patients were detected by ultrasound (US) as hyperechoic foci and categorized as BI-RADS 3-5. The 51 patients further underwent CEUS scan and MRI. The US-BI-RADS combined with CEUS 5-point score system redefined the classification of BI-RADS which was called CEUS-BI-RADS. The diagnostic efficacy ...

ABSTRACTGeneral screening of singleton pregnancies for preterm delivery by adding cervical length measurement with transvaginal ultrasound to second trimester routine fetal ultrasound examination has been advocated1. Reference ranges of cervical length are available from 11 to 40 weeks of gestation.2 In the Nordic countries, second trimester routine ultrasound examinations are performed by specially trained midwife sonographers, and if screening for preterm delivery were to be introduced, cervical length measurements would be done by them. Therefore, we wanted to estimate the resources needed to train midwife sonographers ...

Authors: Parikh AM, Grogan RH, Morón FE Abstract The localization of persistent or recurrent disease in reoperative patients with primary hyperparathyroidism presents challenges for radiologists and surgeons alike. In this article, we summarize the relevant imaging modalities, compare their accuracy in identifying reoperative disease, and outline their advantages and disadvantages. Accurate localization by preoperative imaging is a predictor of operative success, whereas negative or discordant preoperative imaging is a risk factor for operative failure. Ultrasound is a common first-line modality because it i...
