The Case of MRI Repetitions with Direct and Indirect Cost Implications: Evidence from Hacettepe University Hospitals

Özen, İlhan Can
This study investigates the case of repeated MRIs using data from Hacettepe University Hospitals. Results indicate that almost 34% of MRI consultations have to be repeated within the same year due to suboptimal quality that hinders correct assessment and diagnosis. Suboptimal quality refers to; movement artefacts, use of wrong scan technique or sequence, inexperienced reader and/or shortened time intervals. In fact, almost 30% of those repetitions result in a change in diagnosis. Results suggest that the probability of repetition is higher among women and children.

Aims: The purpose of the study was to establish whether the patients presenting with abdominal pain should undergo to contrast enhanced CT (Computed tomography). For this purpose, we have investigated the possible relationship between CRP (C-reactive protein),WBC (White blood cell), neutrophil levels and the presence of pathological findings determined on abdominal pelvic CT images.
Not just about machines: Analysis of MRI quality determinants in the Turkish health system context
Özen, İlhan Can (2021-11-01)
This study aims to investigate the determinants of the qualityMRI in the Turkish healthcare system. The analysis is doneby analysing the referred cases to a major university radiologydepartment in Turkey, and matching the hospital and MRIuse characteristics of the source institutions, where the originalMRI was taken. Quality of MRI was measured by specialistradiologists. The resulting quality was analysed by genderand imaging area characteristics, source institutional quality,MRI use statistics in source in...
Psychometric properties of the Hamilton Depression Rating Scale and other physician-rated psychiatric scales for the assessment of depression in ESRD patients undergoing hemodialysis in Turkey
Gençöz, Faruk; Gençöz, Tülin (Informa UK Limited, 2007-08-01)
This study aimed to examine the reliability and validity of clinician-rated psychiatric scales for end-stage renal disease (ESRD) patients undergoing hemodialysis (HD) treatment in Turkey. For this, the Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HARS), Global Assessment of Functioning (GAF) Scale, Clinical Global Impression (CGI) Scale, and Mini Mental State Exam (MMSE) were administered to 45 ESRD outpatients undergoing HD treatment. Regarding the reliability of HDRS and HARS, ...
Forward problem solution for electrical conductivity imaging via contactless measurements
Gençer, Nevzat Güneri (IOP Publishing, 1999-04-01)
The forward problem of anew medical imaging system is analysed in this study. This system uses magnetic excitation to induce currents inside a conductive body and measures the magnetic fields of the induced currents. The forward problem, that is determining induced currents in the conductive body and their magnetic fields, is formulated. For a general solution of the forward problem, the finite element method (FEM) is employed to evaluate the scalar potential distribution. Thus, inhomogeneity and anisotropy...
Computational modeling of progressive damage and rupture in fibrous biological tissues: application to aortic dissection
Gültekin, Osman; Hager, Sandra Priska; Dal, Hüsnü; Holzapfel, Gerhard A. (Springer Science and Business Media LLC, 2019-5-15)
This study analyzes the lethal clinical condition of aortic dissections from a numerical point of view. On the basis of previous contributions by Gultekin et al. (Comput Methods Appl Mech Eng 312:542-566, 2016 and 331:23-52, 2018), we apply a holistic geometrical approach to fracture, namely the crack phase-field, which inherits the intrinsic features of gradient damage and variational fracture mechanics. The continuum framework captures anisotropy, is thermodynamically consistent and is based on finite str...
