“…It is not surprising that these factors influence enrollment in MRI studies, even among women who previously enrolled in less "invasive" studies. Anxiety about MRI scanning has been reported to be related to fear of enclosed places, pain, the unknown, and apprehension about potential findings (23). It has been reported that as many as 20% of patients may experience claustrophobia severe enough to preclude the completion of attempted MRI, (24) and many of these would be unlikely to agree to screening.…”

Rationale and Objectives-The rates of enrollment of volunteers for brain magnetic resonance imaging (MRI) studies vary by demographic and clinical characteristics. We use data from a large MRI study to identify factors associated with differential enrollment and to examine potential biases this may produce in study results.Materials and Methods-Results from recruitment of 1,431 women into the MRI substudy of the Women's Health Initiative Memory Study (WHIMS-MRI) are described. A sensitivity analysis was conducted to estimate the degree of bias associated with missing data on estimates of risk factor relationships.Results-Of 2,345 women contacted from an established cohort of women older than 70 years of age, 72% consented to undergo screening for WHIMS-MRI. Scanning was ultimately completed on 61%. Completion rates varied according to a range of sociodemographic, lifestyle, and clinical characteristics that may be related to study outcomes. Plausible levels of selective enrollment in magnetic resonance imaging studies may produce moderate biases (< ±20%) in characterizations of risk factor relationships. Adverse events, such as claustrophobia, occurred during 1.7% of the attempted scans and, in 0.8% of instances, led to lost data.Conclusions-Enrollment of older women into brain imaging studies is feasible, although selection biases may limit how well study cohorts reflect more general populations.

“…Published reports typically indicate that 15% of patients describe severe claustrophobic reactions while in the bore of the machine. Apart from the distress caused by this, such reactions can result in the degrading of images obtained, or in premature termination of the procedure [1,2,3,4]. Records at a local hospital for instance, indicate that over a seven year period, 1% of people undergoing MRI could not complete the scan as a result of claustrophobic reactions.…”

“…Common complaints about mri surveillance include claustrophobia and anxiety because of the narrowness of the bore, associated movement restrictions, length of the procedure, loud noise from the machine, or simply worry about the next mri [6][7][8] . To demonstrate the extent of the impact of mri on the general patient population, claustrophobia is experienced by an average of 2.3% of all patients who undergo mri (95% confidence interval: 2.0% to 2.5%), and up to 37% experience moderate-to-high levels of anticipatory anxiety [9][10][11] . Given the noncurative nature of brain metastases and the potential problems that arise from mri, it is important to evaluate the potential impact of clinical surveillance alone.…”
