Chorioangiomas make up 1% of incidentally detected placental mass lesions. These are usually located on the fetal surface of the placenta. 1 Ultrasound with Doppler examination remains the gold standard investigation of choice for the diagnosis, and for differentiat-ing placental chorioangiomas from other placental masses which include degenerated fibroid, organized placental hematoma, partial hydatidiform mole and placental teratoma. Intense vascularity of placental chorioangioma on color Doppler may indicate possible risk of fetal complications. 2 Prenatal diagnosis of chorioangioma with appropriate management should include serial antenatal ultrasound scans with assessment of the placenta and fetus, pulse wave Doppler assessment of the umbilical cord and middle cerebral artery, and","PeriodicalId":29898,"journal":{"name":"Sonography","volume":"336 1","pages":"41 - 42"},"PeriodicalIF":0.4,"publicationDate":"2022-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80651480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Workshop presentations","authors":"Jing Fang, Jacqui Robinson, Daniel Walkley, Alison Deslandes","doi":"10.1002/sono.12324","DOIUrl":"https://doi.org/10.1002/sono.12324","url":null,"abstract":"Sonographers have joined surgeons, GP's and therapists as an integral part of the treatment and recovery journey of patients with hand, wrist, elbow and shoulder injuries. Contemporary treatment options for many injuries and conditions of the hand and upper limb rely on ultrasound imaging and the accuracy it provides for vital diagnostic and therapeutic purposes. This presentation will equip sonographers with the crucial examination skills required to assist surgeons and therapists in the diagnosis of conditions of the hand, wrist, elbow, and shoulder and will provide real-world examples of the importance of ultrasound in day-to-day clinical practice. This presentation will draw on the expertise of senior therapists and specialist upper limb surgeons in the use of ultrasound diagnostically and in treatment plans for the management of various upper limb conditions. It will highlight examples where ultrasound has been used clinically to successfully diagnose selective traumatic and non-traumatic conditions and detail how this has been used in the development of treatment options and patient recovery. It will also consider the higher success rate of ultrasound imaging for needle guidance pro-cedures, the evaluation of soft tissue masses, the identification of foreign bodies, the diagnosis of tendon injuries as well as compres-sion neuropathies and joint disease. This presentation is for the sonographer with little experience in ultrasound examination of the ankle. During the session, we will go through how to complete a basic ankle ultrasound protocol. Scanning of the ankle will be broken down into sections and will begin with the lateral aspect. It will then move to the anterior aspect and then through to the medial aspect. Attendees will leave with the knowledge of how to perform a basic ankle ultrasound and will be armed with a step-by-step process of how to locate and assess important ankle anatomy during their scan. There will be tips and tricks along the way as well as a chance at the end of the session to practice scanning any areas that attendees find problematic. when scanning the acute finger. The workshop will cover anatomy, scan techniques and expected sonographic findings with validation through the presenter's own case studies. Live scanning will reinforce the key concepts in real time and attendees are encouraged to participate through questions. This workshop offers something for all skill levels.","PeriodicalId":29898,"journal":{"name":"Sonography","volume":"22 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74394353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On physical examination, there was evidence of facial asymmetry with the ovoid swelling being firm in consistency and non-tender measuring 5 6 cm in size. The patient was referred for ultrasonography which demonstrated evidence of a well-defined lobulated hypoechoic lesion measuring 2.6 2.8 cm with central vascularity in the superficial lobe of right parotid. Further, there was a similar hypoechoic lesion measuring 2.7 3.0 cm in the deep lobe (Figure 1). The remainder of the right parotid gland showed increased vascularity which was likely reactive (Figure 2). There was no involvement of ipsilateral submandibular gland and contralateral parotid gland. However, there was significant right level Ib cervical lymphadenopathy. Ultrasound imaging was performed using a Toshiba diagnostic ultrasound system (XarioTM 100, Toshiba Medical Systems Corporation, Tochigi, Japan) with a 5 MHz convex array probe. Pleomorphic adenoma, nerve sheath tumors of the facial nerve, and adenoid cystic carcinoma were considered as differentials. Fine needle aspiration cytology (FNAC) confirmed multifocal pleomorphic adenoma and the patient was referred to general surgery department for further management where she underwent total right parotidectomy.","PeriodicalId":29898,"journal":{"name":"Sonography","volume":"2 1","pages":"191 - 193"},"PeriodicalIF":0.4,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85369804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This may be the case but is not shown by the statistical analysis used. The authors would benefit by reassessing the types of variables used in the study and analysing their data using the GLM function in SPSS, which can investigate the actual effect between groups. The interpretation would be slightly different, as the output of this type of analysis provides coefficients with respect to a reference group (dummy variable). That is, the difference in scan time compared to one operator or the absence of pathology. So reporting the finding would follow something like ‘ when two operators attended the scan, on average, scan time increased by XX mins (95% CI: X (cid:1) X mins) compared to a single operator, after adjusting for the presence of pathology. ’ I hope this letter is of some assistance to the authors.","PeriodicalId":29898,"journal":{"name":"Sonography","volume":"26 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77936139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
