Assessing Subject Experience Associated with MRI Examinations: A Cross-Sectional Study from Jaipur, India

Abstract

Background: Magnetic Resonance Imaging (MRI) is an indispensable diagnostic modality; however, the enclosed scanner environment, prolonged examination duration, and high acoustic noise frequently result in patient discomfort and anxiety. These factors may adversely influence patient cooperation, scan tolerance, and image quality. Understanding subject experience is therefore essential for improving patient-centred MRI practice.

Aim: To assess subject experience associated with MRI examinations, with specific emphasis on discomfort, anxiety, phobia, and noise disturbance.

Materials and Methods: A descriptive cross-sectional study was conducted among patients undergoing MRI examinations at a tertiary care imaging centre in Jaipur, India. A total of 299 participants (partial dataset representing approximately 50% of the total PhD sample) were included. Data were collected using a structured, self-administered, closed-ended questionnaire based on a four-point Likert scale. Variables assessed included anxiety inside the MRI scanner, noise disturbance, discomfort due to prolonged immobility, dizziness, metallic taste sensation, warm sensation, and claustrophobic anxiety. Data were analysed using descriptive statistics, including mean, median, standard deviation, interquartile range, and percentages, using SPSS version 23.

Results: The study population comprised 155 males (51.8%) and 144 females (48.2%), with a mean age of 41.9 ± 13.8 years (median: 41 years; range: 11–84 years).
Noise disturbance was the most prevalent complaint, reported by 81.6% of participants. Discomfort related to prolonged scan duration and immobility was reported by 67.2%, while 60.2% experienced anxiety inside the MRI scanner. Less frequently reported symptoms included dizziness (14.4%), metallic or weird taste (6.4%), and warm sensation (6.4%). A prior history of claustrophobic anxiety was reported by 3.3% of participants. The mean Likert score was highest for noise disturbance (3.25 ± 0.74), indicating it as the dominant factor affecting patient experience.

Conclusion: MRI examinations are associated with significant patient discomfort, predominantly due to acoustic noise, prolonged immobility, and scanner-related anxiety. Implementation of targeted interventions such as improved patient counselling, effective communication, and noise-reduction strategies may substantially enhance patient comfort and compliance during MRI procedures.
