The Rationality to Requesting in-ward Magnetic Resonance Imaging Investigation
Abstract
Background: Magnetic Resonance imaging (MRI) is a valuable diagnostic tool by its non-invasive/non-ionizing nature.Objective: This study aims to determine justification of MRI in hospitalized patients at a tertiary provincial referent medical center in a one-year period.Material and Methods: In the present retrospective and descriptive cross-sectional study, 438 admitted patients referred for MRI during 2017 were selected using systematic random sampling. The age, gender, investigated organ, the specialty of requesting physician, MRI with and without contrast, MRI diagnostic outcome were collected using checklists. Descriptive statistics and chi-square test were used for data analysis.Results: The mean age of the patients was 42±26 years-old and female represented 53% of enrolled patients. The most and less prevalent investigated organs were the cerebrum and the orbit. After excluding cancer diagnosis, cancer staging, and therapeutic follow-up exams, MRI request was oriented in 64.3% and 77.2% of positive results was concordant with aforementioned diagnostic orientation (P<0.001). Oriented diagnostic MRI requesting is influenced by age, medical specialists and, investigated organ (P<0.001). The positive MRI is influenced significantly by oriented MRI request, gender, medical specialists and investigated organ (P<0.001). The diagnosis concordance of MRI is influenced significantly by oriented MRI request, medical specialists and investigated organ (P<0.001). Conclusion: Appropriate implementation of medical imaging requires boosting employed rationality by the concerned physicians. The current suboptimal results to requesting MRI rationality should mandate supplementary educational programs as to incite the medical corpus more closely implementing the published medical practice guidelines.
