Comparison of Echocardiography and Computed Tomography/Magnetic Resonance Imaging for Assessing of Pulmonary Vein Stenosis in Children

Pulmonary vein (PV) stenosis is a rare disease with high recurrence and mortality rates. Objective. This study was aimed to evaluate the diagnostic accuracy of echocardiography versus cross-sectional modalities. Material and methods. Our study includes 11 consecutive patients who underwent a comprehensive PV anatomy assessment between April 2018 and June 2019 at Ukrainian Children’s Cardiac Center, Kyiv. Echocardiographic studies of each pulmonary vein followed by computed tomography (CT) or magnetic resonance imaging (MRI) were performed in all patients. A total of 27 CT/MRI studies were performed. Results. There were four patients whose echocardiography findings were completely confirmed by CT/MRI method. In some patients significant stenosis was underestimated by echocardiography. Sensitivity and specificity were 86.4 and 88.9 for echo, as well as 100 and 94.4 for CT/MRI, respectively. Conclusion. This study recognizes the limitations of echocardiography as an imaging tool for pulmonary veins morphology assessment. Cross-sectional studies overcome these limitations and provide excellent morphological as well as functional (MRI) evaluation of pulmonary veins.

Latar Belakang. Insidensi apendisitis perforasi di dunia mencapai 2 per 10.000 kelahiran hidup, untuk proporsi apendisitis perforasi sekitar 25%. Kasus apendisitis di Indonesia berdasarkan data Kementerian Kesehatan RI pada tahun 2009 sebesar 596.132 kasus dengan persentase 3.36% dan meningkat pada tahun 2010 menjadi 621.435 kasus dengan persentase 3.53%. Sedangkan insidensi di RS Hasan Sadikin pada tahun 2017 mencapai 83% pasien yang datang dengan keluhan apendisitis telah mengalami perforasi. Pemeriksaan radiologik seperti computed tomography scan (CT), magnetic resonance imaging (MRI) ataupun ultrasonography (USG) memiliki sensitifitas dan spesifitas yang tinggi untuk mendiagnosis perforasi apendisitis, tetapi alat–alat ini tidak selalu tersedia di institusi–institusi kesehatan negara berkembang. Fibrinogen sebagai faktor koagulasi yang pertama kali ditemukan dalam beberapa penelitian berpotensi digunakan sebagai prediktor perforasi pada pasien apendisitis, pemeriksaan fibrinogen dapat dilakukan sewaktu-waktu, memberikan hasil yang lebih cepat dengan harga yang lebih murah dibandingkan dengan pemeriksaan penunjang lain. Metode. Penelitian observasional analitik dengan pendekatan cross-sectional. Subjek pasien apendisitis periode 1 April 2018 – 31 Desember 2018 yang datang ke Installasi Gawat Darurat RSUP Dr. Hasan Sadikin Bandung dan bersedia mengikuti penelitian. Pasien yang didiagnosis kerja awal sebagai apendisitis akut atau pasien dengan appendisits perforasi dengan gejala peritonitis lokal atau peritonitis difus setelah dilakukan pemeriksaan klinis dan laboratorium. Pasien dilakukan pemeriksaan fibrinogen serum preoperatif, lalu dilakukan operasi dan dicatat hasil temuan operasi yaitu yang mengalami perforasi dan yang tidak mengalami perforasi. Dilakukan pengelompokkan data setelah jumlah subyek penelitian terpenuhi. Hasil. Sebanyak 40 pasien (25 laki-laki, 15 perempuan) terdiagnosis apendisitis berdasarkan Alvarado Score, yang terdiri dari 20 pasien apendisitis akut dan 20 pasien apendisitis perforasi. Akurasi kadar fibrinogen serum dalam memprediksi terjadinya perforasi sebesar 85%. Nilai sensitivitas 90%, nilai spesifisitas 80%. Berdasarkan analisis kurva ROC diperoleh nilai Area Under Curve (AUC) sebesar 0,865 (p = 0,001). Menunjukkan bahwa kadar fibrinogen serum memiliki kemampuan diskriminasi yang tinggi dalam memprediksi terjadinya perforasi pada pasien apendisitis. Kesimpulan. Kadar fibrinogen serum yang meningkat dapat digunakan sebagai prediktor terjadinya perforasi pada pasien apendisitis. Kata kunci. Apendisitis perforasi, fibrinogen, prediktor (ISSN 2723-7494 J Bedah Indonesia. 2020;48:3-14)

AbstractDue to their important phylogenetic position among extant vertebrates, sharks are an invaluable group in evolutionary developmental biology studies. A thorough understanding of shark anatomy is essential to facilitate these studies and documentation of this iconic taxon. With the increasing availability of cross-sectional imaging techniques, the complicated anatomy of both cartilaginous and soft tissues can be analyzed non-invasively, quickly, and accurately. The aim of this study is to provide a detailed anatomical description of the normal banded houndshark (Triakis scyllium) using computed tomography (CT) and magnetic resonance imaging (MRI) along with cryosection images. Three banded houndsharks were scanned using a 64-detector row spiral CT scanner and a 3 T MRI scanner. All images were digitally stored and assessed using open-source Digital Imaging and Communications in Medicine viewer software in the transverse, sagittal, and dorsal dimensions. The banded houndshark cadavers were then cryosectioned at approximately 1-cm intervals. Corresponding transverse cryosection images were chosen to identify the best anatomical correlations for transverse CT and MRI images. The resulting images provided excellent detail of the major anatomical structures of the banded houndshark. The illustrations in the present study could be considered as a useful reference for interpretation of normal and pathological imaging studies of sharks.

AbstractAnal fistula (AF) is a common referral to colorectal surgeons. Management remains challenging and sometimes controversial. Magnetic resonance imaging (MRI) is commonly performed in initial workup for AF. However, reports often lack key information for guiding treatment strategies. It has been shown that with structured radiology reports, there is less missing information. We present a structured MRI template report including 8 key descriptors of anal fistulas, whose effectiveness and acceptability are being assessed in a cross-sectional study (NCT04541238).

AbstractWe investigated the prevalence of magnetic resonance imaging (MRI) findings and their relationship with knee symptoms in women without radiographic evidence of knee osteoarthritis (KOA). This cross-sectional cohort study included 359 Japanese women without radiographic evidence of KOA (Kellgren‒Lawrence grade < 2). All participants underwent T2-weighted fat-suppressed MRI of their knees. Structural abnormalities (cartilage damage, bone marrow lesions [BMLs], subchondral cysts, bone attrition, osteophytes, meniscal lesions, and synovitis) were scored according to the whole-organ MRI score method. Knee symptoms were evaluated using the Knee Injury and Osteoarthritis Outcome Score. Participants were divided into early and non-KOA groups based on early KOA classification criteria. Logistic regression analysis was performed to evaluate the relationship between MRI abnormalities and knee symptoms. Cartilage damage was the most common abnormality (43.5%). The prevalences of cartilage damage, BMLs, subchondral cysts, bone attrition, meniscal lesions, and synovitis were higher in patients with early KOA than in those without. Synovitis (odds ratio [OR] 2.254, P = 0.002) and meniscal lesions (OR 1.479, P = 0.031) were positively associated with the presence of early KOA. Synovitis was most strongly associated with knee pain and might be a therapeutic target in patients with early KOA.

Abstract Background Pancreatic cystic lesions are increasingly identified in persons undergoing abdominal imaging. Serous cystic neoplasms (SCNs) have a very low risk of malignant transformation. Resection of SCNs is not recommended in the absence of related symptoms. The accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) to identify SCNs is not known and may impact clinical care. Aims To evaluate the accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) for the diagnosis of SCN. To see how this can impact the decision to resect suspected SCNs. Methods Retrospective cohort study of patients from the University Health Network with suspected SCNs from 2017–2020 who underwent either a CT or MRI of the abdomen. Reports noting pancreatic cystic lesions were identified and reviewed. Only cases with suspected SCNs were included. Clinical (age, sex, symptoms, treatment) and radiographic (type of imaging, reported cyst characteristics) data was collected. Pathology was reviewed for all cases where the cysts was biopsied or resected during follow-up. The gold standard for the diagnosis for SCN was pathology of resected specimen or EUS-guided biopsy cytopathology showing no evidence of a mucinous lesion, CEA level below 10ug per L and amylase level below 50 U/L. Results 163 patients were included in the study. 99 (61%) were female and 98 (60%) underwent CT scan. EUS-guided biopsy was performed in 24 (15%) of patients and 8 (5%) had surgical resection. Multidisciplinary review was performed in 6 of the 8 cases that went to surgery. Of the resected specimens, 5 (63%) were SCN, 1 was a mucinous cystic lesion, 1 was a neuroendocrine tumor and 1 was a carcinoma. Two patients underwent EUS evaluation prior to surgical resection. In one case SCN was resected when EUS reported an undetermined cyst type. Reasons for surgical resection were: the diagnosis of serous cyst was not definitive (n=5), symptoms (n=2), and high-risk mucinous cystic neoplasm identified on EUS (n=1). Of 30 patients with pathology available, 15 (50%) were confirmed to have a SCN. CT and MRI had a sensitivity, specificity, positive predictive value and negative predictive value of 93%, 25%, 52% and 80%, respectively. Conclusions Surgical resection for SCN lesions is driven by diagnostic uncertainty after cross-sectional imaging. Multidisciplinary review and EUS evaluation may improve diagnostic accuracy and should be considered prior to surgical resection of possible SCN lesions. Funding Agencies None

Tarsometatarsal Joint

Background Fibrocartilaginous coalition of the third tarsometatarsal joint has been indicated as an extremely rare form of tarsal coalition in the radiological literature, and most articles concerned with tarsal coalition do not mention involvement of this joint. Only two reports written in the English language that approach this subject were found, an orthopedic report and an anthropological report. Purpose To evaluate the prevalence of this finding and discuss and illustrate the radiological characteristics of this coalition. Material and Methods A retrospective analysis of 614 computed tomography or magnetic resonance imaging scans of the ankle and/or foot, acquired at a health service within a period of three months, was performed to assess the prevalence of this coalition. Results Of the examinations characterized as valid for analysis for the purposes of the study, 17 cases compatible with fibrocartilaginous coalition of the third tarsometatarsal joint were found, thus indicating an involvement of approximately 2.97% of the examined feet. Conclusion Our radiological findings are typical, and the prevalence found in this study was statistically significant, being similar to that described in the anthropological report (3.2%–6.8%).

Computed tomography (CT) and magnetic resonance imaging (MRI) are enabling more precise diagnosis and treatment planning in patients with diseases of the larynx. The aim of this article is to describe the role of these methods in assessment of the laringeal diseases and key local anatomic characteristics important for spread of the disease. CT and MRI have a valuable contribution to the staging of the tumors due to the possibility to show the relationship to the ventricular complex, involvement of the subumucosal spaces, defining craniocaudal and anterposterior extension, laringeal cartilage invasion, as well as regional lymph node metastases.

Study Designs

Objective:To find out whether the neurodevelopmental disorders autism and childhood-onset schizophrenia have a common developmental pathway and whether the abnormalities detected are ‘disorder-specific’, by reviewing magnetic resonance imaging (MRI) studies.Methods:As a result of a Medline search, we were able to access 28 studies on autism and 12 studies on childhood-onset schizophrenia, which focused on children and adolescents.Results:Larger lateral ventricles were found to be a common abnormality in both disorders. ‘Disorder-specific’ abnormalities in patients with autism were larger brains, a larger thalamic area, and a smaller right cingulate gyrus. Subjects with childhood-onset schizophrenia were found to have smaller brains, a smaller amygdalum and thalamus, and a larger nucleus caudatus. In subjects with childhood-onset schizophrenia, abnormalities appeared to progress over a limited period of time.Conclusions:Because the study designs varied so much, the results should be interpreted cautiously. Before abnormalities found in the disorders can be designated as equal or ‘disorder-specific’, it will be essential to perform large longitudinal and cross-sectional follow-up studies.
