Publication Demonstration of corkscrew collaterals in buerger's disease by superb microvascular imaging(Elsevier, 2019-09-01) Kandemirli, Sedat Giray; Gürsel, Başak Erdemli; ERDEMLİ GÜRSEL, BAŞAK; Yolgösteren, Atıf; YOLGÖSTEREN, ATIF; Nas, Ömer Fatih; NAS, ÖMER FATİH; Tıp Fakültesi; 0000-0002-4467-3915; AAH-6568-2021; AAG-8561-2021; AAG-2372-2021Publication Diagnostic utility of superb microvascular imaging in depiction of corkscrew collaterals in Buerger's disease(Wiley, 2020-05-27) Nas, Ömer Fatih; Kandemirli, Sedat Giray; Erdemli Gürsel, Başak; Bilgin, Cem; Korkmaz, Barış; Yolgösteren, Atıf; İnecikli, Mehmet Fatih; NAS, ÖMER FATİH; Kandemirli, Sedat Giray; ERDEMLİ GÜRSEL, BAŞAK; BİLGİN, CEM; KORKMAZ, BARIŞ; YOLGÖSTEREN, ATIF; İNECİKLİ, MEHMET FATİH; Tıp Fakültesi; Kalp ve Damar Cerrahisi Ana Bilim Dalı; 0000-0002-4467-3915; AAG-2372-2021; HHS-7433-2022; AAK-5124-2020; AAG-8561-2021; AAH-6568-2021; A-1409-2017; FHT-9776-2022Purpose To evaluate the corkscrew collaterals in Buerger's disease by superb microvascular imaging (SMI) and power Doppler ultrasonography (PDU). Methods We evaluated with SMI and PDU 14 patients with Buerger's disease in whom corkscrew collaterals had been identified on digital subtraction angiography (DSA). Corkscrew collaterals were classified on DSA and PDU based on their size and morphology. Results A total of 17 vascular regions of collateral vessel formation were assessed. Based on DSA classification, there were three cases of type I collaterals (arterial diameter of >2 mm with large helical pattern), seven cases of type III collaterals (arterial diameter of 1-1.5 mm with small helical pattern), and seven cases of type IV collaterals (arterial diameter of <1 mm with tiny helical pattern). On PDU, all type I collaterals on DSA appeared as "large snake" images, all type III collaterals on DSA appeared as "small snake" images, and all type IV collaterals on DSA appeared as dots. SMI imaging, both in color and monochrome mode, provided superior demonstration of the continuity of the vessel of large or small "snake" images. In cases appearing as dot pattern on PDU, color SMI was able to show continuity of the flow signal as a helical pattern. Discussion SMI is a promising new Doppler imaging technique that is superior to conventional power Doppler imaging in depiction and identification of corkscrew collaterals in Buerger's disease.Publication Superb microvascular imaging in assessment of synovitis and tenosynovitis in juvenile idiopathic arthritis(Lippincott Williams & Wilkins, 2021-03-01) Kandemirli, Sedat Giray; Çicek, Fatih; Erdemli Gürsel, Başak; Bilgin, Cem; Kiliç, Sara Sebnem; Yazıcı, Zeynep; Çicek, Fatih; ÇİÇEK, FATİH; Erdemli Gürsel, Başak; ERDEMLİ GÜRSEL, BAŞAK; Bilgin, Cem; BİLGİN, CEM; Kiliç, Sara Sebnem; KILIÇ GÜLTEKİN, SARA ŞEBNEM; Yazıcı, Zeynep; YAZICI, ZEYNEP; Tıp Fakültesi; Radyoloji Ana Bilim Dalı; 0000-0001-7348-7081; 0000-0001-8571-2581; AAH-1658-2021; HHS-7433-2022; JKI-5906-2023; AAH-6568-2021The aim of this study is to evaluate the diagnostic utility of superb microvascular imaging (SMI) in assessment of synovitis/tenosynovitis in juvenile idiopathic arthritis in comparison to power Doppler ultrasound. Thirty juvenile idiopathic arthritis cases with active clinical findings and ultrasound features of effusion and/or tenosynovitis were further imaged with power Doppler and SMI. For classification of synovial inflammation, a semiquantitative scale (4 points) adopted by Outcome Measures in Rheumatology was used.A total of 35 knee, 2 hip, 2 ankle, 2 wrist, 2 elbow joints, and 6 flexor hallucis longus/tibialis posterior tenosynovitis were assessed. In knee joint, power Doppler and SMI scales were the same for 23 (65.7%) joints, SMI upgraded scale from 0 to 2 in single joint (2.9%); 1 to 2 (14.3%) in 5 joints; and 2 to 3 (17.1%) in 6 joints. For other joints, power Doppler and SMI scales were the same for 5 (62.5%) joints. Superb microvascular imaging upgraded scale from 1 to 2 (25%) in 2 joints and 1 to 3 (12.5%) in a single joint. For flexor hallucis longus/tibialis posterior tenosynovitis, power Doppler and SMI scales were the same for two cases (33.3%). Superb microvascular imaging upgraded scale from 0 to 2 in two cases (33.3%); and 2 to 3 (33.3%) in 2 cases. There was no case of SMI scale downgraded compared with power Doppler scale.Superb microvascular imaging is a feasible technique in the assessment of synovial inflammation and tenosynovitis in juvenile idiopathic arthritis. Superb microvascular imaging has higher sensitivity compared with power Doppler ultrasound in depiction of increased vascularity.Publication Morphometric shape analysis of corpus callosum in children with down syndrome(Sage Publications Inc, 2023-08-31) Gürsel, Başak Erdemli; Ercan, İlker; Şahin, İbrahim; Öngen, Gökhan; ERDEMLİ GÜRSEL, BAŞAK; ERCAN, İLKER; Şahin, İbrahim; ÖNGEN, GÖKHAN; Tıp Fakültesi; Radyolog Ana Bilim Dalı; 0000-0002-2382-290X; 0000-0002-0047-1780; AAH-6568-2021; HII-7787-2022; ABF-2367-2020; JJO-9241-2023Down syndrome (DS) is characterized by varying degrees of mental retardation and delay in neurocognitive functions. Herein, we analyzed the morphometric shape of the corpus callosum (CC) in children with DS. Twenty-three DS cases underwent magnetic resonance imaging and have grossly normal CC, and 23 control group cases were included in this retrospective study (2012-2020). The CC was obtained from T2-weighted mid-sagittal images, and certain anatomical points were marked on the CC. Statistical geometric shapes and deformations of CC were evaluated for both groups. The age range of patients with DS and control group was 6 to 42 months. A statistically significant difference was found in the shape of CC between the groups (P < .001). Deformation was most evident in the splenium in the DS group.Publication Cardiac hydatid disease and extracardiac organ involvement: A tertiary single-center experience(Istanbul Training & Research Hospital, 2021-05-01) Cam, Isa; Karauzum, Kurtulus; Karauzum, Irem; Ozer, Torehan; Yalniz, Ahmet; Cakir, Ozgur; Cebeci, Hakan; Omay, Oguz; Ciftci, Ercument; Sahin, Tayfun; Anik, Yonca; Gursel, Basak Erdemli; ERDEMLİ GÜRSEL, BAŞAK; Tıp Fakültesi; Radyoloji Ana Bilim Dalı; 0000-0001-9551-2364; 0000-0003-3253-1554; 0000-0001-6565-9488; 0000-0002-0851-2946; E-4900-2015; G-3388-2018; AAD-5011-2021; AAH-6568-2021; GXW-0700-2022; G-4427-2018Introduction: Cardiac involvement is rare in hydatid cyst disease, which accounted for 0.5%-2% of all hydatidosis cases. Cardiac cysts usually occur as part of a wider infestation with extracardiac involvement. This study aimed to describe the general characteristics, imaging findings, and range of organ involvement in cases of cardiac hydatid disease.Methods: Retrospective assessment of cardiac hydatid disease records, between 2007 and 2019, was undertaken to identify patients with cardiac hydatidosis. Hydatid cysts were assessed by transthoracic echocardiography, magnetic resonance imaging, and computed tomography. Clinical symptoms, treatment modalities, and follow-up were also evaluated.Results: Over the study period, 22 (13 males: 59.1%; mean age: 43.1 years; range: 12-63 years) patients with 24 cardiac hydatid cysts were identified. The most common symptom was chest pain, which occurred in 13 (59.1%) patients, Cardiac cysts were located in the left ventricle (n=10, 41.7%), right ventricle (n=5, 20.8%), interventricular septum (n=5, 20.8%), and pericardium (n=4, 16.7%). Extracardiac involvement was present in 14 (63.6%) patients, most commonly affecting the liver (n=10, 45.4%), but in 8 (36.3%) patients, there was no extracardiac organ involvement. Cardiac hydatid cysts were surgically removed in 20 (90.9%) patients.Conclusion: Cardiac hydatid disease is very uncommon, with the left ventricle as the most commonly affected structure in this series. Chest pain was the most common presenting symptom. Extracardiac involvement is common, so patients with cardiac hydatid cysts should be investigated for involvement of other organs.Publication Corpus callosum in schizophrenia with deficit and non-deficit syndrome: A statistical shape analysis(Bmj Publishing Group, 2021-10-27) Türk, Yaşar; Ercan, İlker; Şahin, İbrahim; Gürsel, Başak Erdemli; Uzunoğlu, Arda; Oğe, Cem; Beyazyüz, Elmas; Albayrak, Yakup; ERCAN, İLKER; Şahin, İbrahim; ERDEMLİ GÜRSEL, BAŞAK; Uzunoğlu, Arda; Tıp Fakültesi; Biyoistatistik Ana Bilim Dalı; ABF-2367-2020; HII-7787-2022; AAH-6568-2021; IAK-9330-2023Background The corpus callosum (CC) is the most targeted region in the cerebrum that integrates cognitive data between homologous areas in the right and left hemispheres.Aims Our study used statistical analysis to determine whether there was a correlation between shape changes in the CC in patients with schizophrenia (SZ) (deficit syndrome (DS) and non-deficit syndrome (NDS)) and healthy control (HC) subjects.Methods This study consisted of 27 HC subjects and 50 schizophrenic patients (20 with DS and 30 with NDS). 3 patients with DS and 4 patients with NDS were excluded. Three-dimensional, sagittal, T1-spoiled, gradient-echo imaging was used. Standard anatomical landmarks were selected and marked on each image using specific software.Results As to comparing the Procrustes mean shapes of the CC, statistically significant differences were observed between HC and SZ (DS+NDS) (p=0.017, James's F-j=73.732), HC and DS (p<0.001, James's F-j=140.843), HC and NDS (p=0.006, James's F-j=89.178) and also DS and NDS (p<0.001, James's F-j=152.967). Shape variability in the form of CC was 0.131, 0.085, 0.082 and 0.086 in the HC, SZ (DS+NDS), DS and NDS groups, respectively.Conclusions This study reveals callosal shape variations in patients with SZ and their DS and NDS subgroups that take into account the CC's topographic distribution.
