    Purpose: To compare the effectiveness of computed tomography (CT) and magnetic resonance imaging (MRI) in the staging of neuroblastomas according to the International Neuroblastoma Risk Group Staging System (INRGSS). Material and methods: In this single-centre retrospective study we identified a total of 20 patients under the age of 18 years, who were admitted to our hospital with neuroblastoma between January 2005 and May 2018, and who had both CT and MRI examination. The INRGSS stages of tumours were evaluated by CT scan and MRI. Then, stages of tumours were described according to the INRGSS for CT and MRI, separately. The Spearman rank correlation test was used for statistical analysis. The p-value < 0.05 was considered as statistically significant. Results: The median age was 11 months, and the age range was one month to nine years. In our results; both MRI and CT were significant in the determination of radiological staging of NBL, p < 0.001 and p = 0.002, respectively. MRI was superior to CT in radiological staging. MRI was also superior for the detection of intraspinal extension, involvement of multiple body compartments, metastatic disease, and bone marrow infiltration. CT was more useful to consider the relationship between tumours and vascular structures. Conclusions: MRI and CT have high diagnostic accuracy rates in the staging of pre-treatment neuroblastomas. MRI is important in pre-treatment evaluation of neuroblastomas because of the higher detection of metastases as well as the lack of ionising radiation

    Objectives: In this study, a comparison of cardiac magnetic resonance imaging (MRI) and simultaneous transthoracic echocardiography data were obtained from patients with great artery transposition (TGA), who underwent arterial switch operation (ASO) surgery. In to discover the most effective and optimal viewing method during long-term follow-ups. Materials and Methods: This retrospective cohort included 20 TGA patients (16 male, 4 female), which had ASO surgery. Along with cardiac MRI and transthoracic echocardiography data were obtained from the images. The mean age was 93.00±29.82 months (60-144). Seventeen patients had TGA only. However, 3 patients with TGA included an existing ventricular septal defect. Results: We showed a meaningful correlation between echocardiographic variables (left ventricle dilatation of the left ventricle function of the aorta failure, myocardial performance index) and MRI parameters (ejection fraction of left ventricle dilatation of the left ventricle function of the aorta insufficiency). Conclusion: TGA patients require careful pre and post operative evaluation, anatomical and a functional use of cardiac indicators. For this purpose, both echocardiography and MRI are useful, safe, and trustworthy methods of diagnosis. Choosing the optimal imaging technique and lifetime reoccurring assessments of the left ventricle function is of vital importance in foreseeing complications, preventing morbidities, and creating a protocol. In clinical practice, the myocardium performance index provides values similar to that of the MRI about the left ventricle dilatation and left ventricle dysfunction. These results provide awareness about the use of specific parameters and the use of information based on quantitative data
