    (Georg Thieme Verlag, 2020) Prosch, Helmut; Radzina, Maija; Dietrich, Christoph F.; Nielsen, Michael Bachmann; Baumann, Sven; Ewertsen, Caroline; Jenssen, Christian; Kosiak, Wojciech; Kratzer, Wolfgang; Lim, Adrian; Popescu, Alina; Mitkov, Vladimir; Schiavone, Cosima; Wohlin, Martin; Wüstner, Matthias; Cantisani, Vito; N/A; Kabaalioğlu, Adnan; Doctor; N/A; Koc University Hospital; N/A
    Background: Despite the increasing role of ultrasound, structured ultrasound teaching is only slowly being integrated into the curricula of medical schools and universities all over Europe. Aim: To survey the current situation at European universities regarding the integration of ultrasound in student medical education and to report on models of student ultrasound training from selected European universities. Methods: A questionnaire survey focusing on the implementation of curricular ultrasound education was sent out to the 28 presidents of the national ultrasound societies of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB), who were asked to distribute the questionnaires to the medical universities of their countries. Results: Overall, 53 questionnaires were returned from 46 universities in 17 European countries. In most of the universities (40/46 universities, 87%), the theoretical background of ultrasound is taught. However, in only a minority of universities is ultrasound integrated in anatomy courses (8/46 universities, 17%) or basic science courses (16/46 universities, 35%). Practical skills in ultrasound are taught in 56% of the universities (26/46 universities) and tested in a practical exam in seven of the responding universities (15%). The number of hours in which ultrasound was taught ranged from one to 58 (mean, seven). The respondents reported that lack of time and limited faculty funding were major hurdles. Conclusion: According to our survey, only a minority of European universities has integrated ultrasound into the preclinical curriculum thus far. Future EFSUMB initiatives will continue to promote the introduction of ultrasound as an integrative part of the core curriculum of student medical education, and the preparation of proper teaching material.

    Cystic renal diseases: role of ultrasound. part II, genetic cystic renal diseases
    (Societatea Romana de Ultrasonografie in Medicina si Biologie, 2022) Gunduz, Nesrin; Keven, Ayse; Durmaz, Emel; Aslan, Mine; Güneyli, Serkan; Kabaalioğlu, Adnan; Faculty Member; Doctor; School of Medicine; School of Medicine; 36622; N/A
    Kidney cysts are quite common in adults. Though small simple renal cysts in an adult over 30-40 years of age are not too unusual, however, if the same cysts are seen in a child, and especially if there are additional findings, then several diagnostic possibilities may come to mind. The role of ultrasound, together with the help of intravenous contrast agents and Doppler mode, are very critical in describing the morphologic features and follow-up of the complex or multiple and bilateral renal cysts. These sonographic signs are occasionally specific for diagnosis, but in many cases sonographic clues should be evaluated together with the other genetic and clinical data to reach diagnosis. The first part of this pictorial essay included the introduction into the subject and the classification of non-genetic cystic renal diseases. The key features for the non-genetic cystic renal diseases are illustrated. In the second part, eye-catching features of genetic cystic renal diseases are demonstrated. © 2022 Societatea Romana de Ultrasonografie in Medicina si Biologie. All rights reserved.

    Imaging appearance of post umbilical venous catheter displacement: liver collections in children
    (Societatea Romana de Ultrasonografie in Medicina si Biologie, 2021) Keven, Ayşe; Durmaz, Emel; Çeken, Kağan; N/A; Kabaalioğlu, Adnan; Doctor; N/A; Koç University Hospital; N/A
    Umbilical venous catheters (UVCs) have become a part of routine perinatal care. In the case of its misplacement, extravasation into liver parenchyma might be observed and unusual findings might be detected and a suspicion of tumoral lesions emerges during the ultrasound examination. To avoid the unnecessary liver biopsies and catastrophic complications of UVC misplacement in the pediatric population, clinicians and radiologists must be familiar with the radiological findings. We aimed to present sonographic and computed tomographic images of liver collections resulting from UVC malposition.

    Interobserver and intraobserver reliability in sonoelastographic assessment of thyroid nodules
    (Lippincott Williams and Wilkins (LWW), 2023) Duman, Emrah; Aslan, Ahmet; Buz, Aysenur; Sancak, Seda; Aslan, Mine; Fersahoglu, Ayse Tuba; Okuroglu, Nalan; Onur, Ender; N/A; Kabaalioğlu, Adnan; Doctor; N/A; Koç University Hospital; N/A
    Background: Thyroid ultrasonography is the first and perhaps most fundamental step for the radiological distinction of benign and malignant nodules. In this study, 2 radiologists reviewed the sonoelastographic and Doppler images of thyroid nodules and evaluated for the intraobserver and interobserver reliability. Purpose: We aimed to determine confusing nodule identifiers and sonographic features differently defined by observers. Methods: A total of 157 nodules in 91 patients (male/female, 72:19) with ages ranging from 18 to 72 years old were included in the study. Ultrasonographic images and video clips of the nodules were obtained and presented to 2 reviewers unaware of the cytopathology results. Two observers defined the characteristics of the nodules based on previously determined criteria. Then, intraobserver and interobserver correlation coefficients were calculated for each subcategory. Results: In the grayscale ultrasonographic examination, varying degrees from low to high interobserver correlation coefficients were obtained for different subcategories (between κ = 0.359 and κ = 0.821). In color Doppler examination, we obtained medium correlation coefficients (κ = 0.493 and κ = 0.553). On the other hand, there was a high correlation coefficient in tissue compression elastography (κ = 0.617 and κ = 0.638). According to our study results, elastographic pattern, shape of the nodule, presence of echogenic foci, and pathological lymph nodes are better predictors to determine the malignant potential of thyroid nodule with higher interobserver correlation. Therefore, these criteria may be used primarily for the evaluation of thyroid nodules. The intraobserver correlation coefficient was higher in the practitioner with longer experience, suggesting the importance of professional practice period on the decision-making process.

    Cystic echinococcosis, review and illustration of non-hepatic manifestations
    (Societatea Romana de Ultrasonografie in Medicina si Biologie, 2020) Dietrich, Christoph F.; Douira-Khomsi, Wiem; Gharbi, Hassen; Sharma, Malay; Cui, Xin Wu; Sparchez, Zeno; Richter, Joachim; Atkinson, Nathan S.S.; Schreiber-Dietrich, Dagmar; Dong, Yi; N/A; Kabaalioğlu, Adnan; Doctor; N/A; Koç University Hospital; N/A
    Cystic echinococcosis (CE) or hydatidosis (hydatid cysts), is an infection with a wide spectrum of manifestations, from asymptomatic infection to fatal disease. Ultrasound (US) allows screening, diagnosis, differential diagnosis, treatment guidance and follow-up of CE under many circumstances. Hydatid cysts are predominantly observed in the liver but many other organs can be involved. As part of a series of publications, herewith we present a review describing the characteristic imaging features of the broad variety of organs which can be involved.

    Patellofemoral anatomical measurements on mri in patient with suprapatellar fat pad edema and mass effect
    (Coll Physicians, Surgeons Pakistan, 2022) Ediz, Suna Sahin; Senturk, Senem; N/A; Kabaalioğlu, Adnan; Doctor; N/A; Koç University Hospital; N/A
    Objective: To evaluate the impact of patellofemoral joint anatomical measurements of patients with anterior knee pain who were diagnosed with suprapatellar fat pad (SPFP) impingement syndrome (SP-FPIS) by magnetic resonance imaging (MRI). Study Design: A prospective, descriptive study. Place and Duration of Study: Goztepe Education and Research Hospital, between March 2015 and June 2019. Methodology: The study included 34 patients (Group 1) and 34 healthy volunteers (Group 2) who were referred to the radiology clinic with anterior knee pain; they underwent MRI and diagnosed with SP-FPIS. Twenty-three anatomical measurements such as SPFP cranio caudal length (CC), anteroposterior length (AP), oblique length (OBL), patellar length (PL), patellar tendon length (PTL), Insall Salvati Index (ISI), patellar cartilage distal-tibial tubercle (TT), patellar cartilage length (PCL), Modified Insall Salvati Index (MISI), patellotrochlear cartilage length (TCL), lateral trochlear inclination angle (LTI), etc. related to the morphological structure of SPFP and patellofemoral joint were evaluated and compared in both groups. Results: The mean age of groups 1 and 2 was 45.62 +/- 10.87 and 41.47 +/- 11.98 years, respectively. There was a statistically significant difference in patients with SP-FPIS in PL, PT, TT, PC, MISI, TC, PTI, MF, PHY, PPI, MT, LTI, CC, AP, and OBL measurements compared with the control group (p<0.05). In the logistic regression analysis performed to evaluate the effect of statistically significant parameters on anterior knee pain, the probability of SP-FPIS increases 1.5 times as PTL increases among the groups, while the risk of SP-FPIS decreases 0.78 times as LTI decreases (p<0.05). Conclusion: There is a predisposing effect of PTL increase in SP-FPIS development, while LTI decrease has a protective effect. These results will guide future studies for the development and/or modification of treatment methods.

    The role of intraoperative ultrasonography in detection of hepatic vein variations in living donor liver transplantation
    (Springer International Publishing AG, 2022) Kesimal, Uğur; Çeken, Kağan; Dinçkan, Ayhan; Durmaz, Emel; Çubuk, Metin; Apaydın, Ali; Sindel, Timur; N/A; Kabaalioğlu, Adnan; Doctor; N/A; Koç University Hospital; N/A
    Background With advances in surgical techniques and immunosuppression, liver transplantation has become the most effective treatment of acute and chronic liver failures. Evaluation of vascular anatomy and detection of hepatic vascular variations prior to surgery, especially transplantation surgery, can help reduce complications in both the donor and the recipient. Intraoperative ultrasonography (IOUS) is known to be beneficial during planning of the transplantation surgery, and can help direct the surgery itself. Objectives To our knowledge, there are no existing studies that evaluate the number and diameter of segment 5 and 8 branches that need to be anastomosed with IOUS. Patients and methods In this study, considering surgical anatomical evaluation as the gold standard, IOUS findings were compared to computed tomography angiography (CTA) findings. 40 patients were included in the study. Results The average diameters of segment 8 branches that were anastomosed and not anastomosed were significantly different when measured by IOUS (p = 0.016); however, no such statistically significant difference was found in measurements made with CTA (p = 0.89). Conclusion CTA is superior to IOUS in detecting segment 5 and 8 veins draining into the middle hepatic vein. However, IOUS is more accurate in predicting which vessels are going to be anastomosed. For a complete and accurate assessment, both imaging modalities should be used to complement each other, and their respective advantages and disadvantages should be known.

    (Georg Thieme Verlag Kg, 2021) Srivastava, David; Roesch, Stephanie Simone; Dietrich, Christoph F.; Chaubal, Nitin; Thomsen, Thomas; N/A; Kabaalioğlu, Adnan; Doctor; N/A; Koç University Hospital; N/A
    Infective focal liver lesions (FLL) are commonly encountered in clinical practice, with bacterial hepatic abscesses accounting for half of the visceral abscesses diagnosed. Accurate diagnosis of suspected hepatic infections is imperative for selecting the most appropriate therapy and preventing complications. The current review aims to update on the use of ultrasound and contrast-enhanced ultrasound (CEUS) to detect and characterize infective liver lesions.

    Assessment of the optic nerve, optic disc, and perineural area using shear-wave elastography in patients with multiple sclerosis
    (Wiley, 2021) Şahin Ediz, Suna; Atalay, Başak; Aydın Cantürk, İlknur; Kabaalioğlu, Adnan; Faculty Member; Koç University Hospital
    Purpose: to observe and describe the stiffness changes of the optic nerve in the patients with multiple sclerosis (MS) with or without optic neuritis and healthy adults via shear wave elastography (SWE). Methods: 70 optic nerves from 35 patients with MS and 60 optic nerves from 30 healthy subjects were included prospectively in the study. The optic nerve (ON), optic disc (OD), and perineural area were evaluated with SWE and optic nerve sheat diameter (ONSD) was measured by ultrasound. Results: The mean age of patients was 39.68 +/- 9.99 years. There was no statistically significant difference between the groups in terms of ONSD, SWE ON, SWE OD, and SWE perineural area levels (P > .05). In the MS group; No statistically significant difference was found between patients with and without optic neuritis for the mean age, gender distribution, duration of MS, types of MS, ONSD, SWE ON, SWE OD, SWE perineural area, and Expanded Disability Status Scale (EDSS) scores (P > .05). No statistically significant difference in terms of ONSD, SWE ON, SWE OD, and SWE perineural area between the MS patients with or without optic neuritis and the control group (P > .05). Conclusion: shear wave elastography measurements of the optic nerve, optic disc, and perineural area do not contribute to the evaluation of optic neuritis in a patient with MS.
