“…In the study most patients declared that they had not received any information from the health personnel prior the examination and also as indicated in Table 3, most of the patients who had no prior information were anxious, this showed that when little or no information are given to the patients it creates worry hence increasing anxiety [7].The other patients who affirmed to have had receive knowledge and were still anxious maybe due their inability to absorb information given to them by their caregivers confirming the research carried out by Sarji et al, [8].…”

Abstract:Background: Anxiety is a feeling of tension associated with a sense of threat of danger when the source is unknown. Anxiety disorders are often associated with common age related medical and chronic conditions such asthma, thyroid disease, coronary artery disease, dementia and sensory loss. Most diagnostic medical imaging has been seen to be associated with some level of anxiety. Aim: The aim was to investigate and compare the anxiety levels of women undergoing ultrasound examination. Methods: A quantitative method with descriptive design was used for the study using closed-ended and few open-ended questionnaires with 100 participants. Data collected were analyzed using the Statistical and Packages for Social Sciences Version 20.0 and Microsoft excel. Result: The result showed that there was no difference between the pre and post procedural anxiety in the patient and one of the major causes of anxiety was lack pre-procedural information and fear of the outcomes of the examination being done. Conclusion: It was concluded that the patients feel anxious before and after an ultrasound examination.

“…Higher rates of claustrophobia have been reported among middleaged women compared with the rates reported among other demographic groups ( 14 ), and a correlation with higher education levels and higher socioeconomic status has been reported ( 15 ). Although hypnosis ( 16 ) and anxiolytic agents such as lorazepam or diazepam can be used effectively to reduce claustrophobia, they may not be generally accepted for screening.…”

Purpose:To determine reasons for nonparticipation in a trial of supplemental screening with magnetic resonance (MR) imaging after mammography and ultrasonography (US). Materials and Methods:Women ( n = 2809) at elevated risk of breast cancer were enrolled in the American College of Radiology Imaging Network 6666 US Screening Protocol at 21 institutions. Fourteen institutions met technical and experience requirements for this institutional review board-approved, HIPAA-compliant substudy of supplemental screening with MR imaging. Those women who had completed 0-, 12-, and 24-month screenings with mammography combined with US were considered for a single contrast materialenhanced MR examination within 8 weeks after completing the 24-month mammography-US screening. A total of 1593 women had complete MR substudy registration data: 378 of them were ineligible for the study, and 1215 had analyzable data. Reasons for nonparticipation were determined. Demographic data were compared between study participants and nonparticipants. Results:Of 1215 women with analyzable data, 703 (57.9%), with a mean age of 54.8 years, were enrolled in the MR substudy and 512 (42.1%) declined participation. Women with a 25% or greater lifetime risk of breast cancer were more likely to participate (odds ratio, 1.53; 95% confidence interval: 1.10, 2.12). Of 512 nonparticipants, 130 (25.4%) refused owing to claustrophobia; 93 (18.2%), owing to time constraints; 62 (12.1%), owing to fi nancial concerns; 47 (9.2%), because their physician would not provide a referral and/or did not believe MR imaging was indicated; 40 (7.8%), because they were not interested; 39 (7.6%), because they were medically intolerant to MR imaging; 29 (5.7%), because they did not want to undergo intravenous injection; 27 (5.3%), owing to additional biopsy or other procedures that might be required subsequently; 21 (4.1%), owing to MR imaging scheduling constraints; 11 (2.2%), because of the travel required; seven (1.4%), owing to gadolinium-related risks or allergies; and six (1.2%), for unknown reasons. Conclusion:Of 1215 women with elevated breast cancer risk who could, according to protocol guidelines, undergo breast MR imaging, only 57.9% agreed to participate.q RSNA, 2010

“…Claustrophobia has been well recognized in MRI. It has been reported that up to 35% of patients undergoing MRI experience claustrophobia (Sarji, Abdullah, Kumar, Tan, & Narayanan, 1998) preventing imaging in 0.88% to 4.3% of cases (Danterndorfer, Wimberger, Katschnig, & Imhoff, 1991;Flaherty & Hoskinson, 1989). In PET, the length of the study, the size of the imaging bore, and patient positioning are comparable to that of MRI; hence, encountering claustrophobia in patients undergoing PET imaging is to be expected with similar prevalence.…”
