Introduction:
Evaluating patient comfort and acceptance is essential when introducing new imaging technologies. The compact 3T (C3T) MRI system features a unique ergonomic design compared to conventional 60-cm bore whole-body 3T MRI systems (WB3T). This study focuses on comparing the patient experience for brain exams between the C3T and WB3T systems.
Methods:
Fifty adult patients undergoing clinically indicated brain MRI exams were imaged using both the C3T and WB3T systems. After completing both scans, participants completed a 12-item questionnaire assessing various aspects of their MRI experience using a 5-point Likert scale. Key areas of evaluation included comfort, noise, vibration, and overall preference.
Results:
Survey responses showed that patients reported a more favorable experience with the C3T scanner in several categories, particularly regarding the exam room environment, noise levels, perceived vibrations, and preference for future scans. Both systems were rated as "very desirable" overall, indicating high levels of patient acceptance for each platform.
Conclusion:
The compact 3T MRI system offers a patient experience that is comparable to or better than conventional whole-body MRI systems for brain exams. These findings support the integration of the C3T system into clinical practice, especially in environments prioritizing patient comfort and satisfaction.
Implications For Practice:
By understanding the patient experience on the C3T, it will help to inform future designs and benefits for MRI systems. This study shows that patients find the C3T system comparable or superior to conventional whole-body 3T scanners in comfort, noise, and overall preference. These results suggest the C3T may support improved patient compliance, reduced motion, and greater efficiency in clinical workflows. Findings may also guide MRI manufacturers toward ergonomic, patient-centered innovations in both research and practice.

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
