Psychological characteristics and satisfaction for the whole-body MRI in cancer screening.

Whole-body magnetic resonance imaging (WB-MRI) is an all-in-one non-invasive technique that can be used also in early cancer diagnosis in asymptomatic individuals. The aim of this work was to identify the personal characteristics predicting the satisfaction for the WB-MRI in a sample of healthy subjects. Before undergoing a WB-MRI examination, 154 participants completed a questionnaire covering sociodemographics (age, gender, education), personality traits (agreeableness, conscientiousness, emotional stability, extroversion, openness), and expectations about the procedure (expected usefulness, risks, noise, lack of air, duration). After the examination, participants reported their satisfaction with the WB-MRI. Results showed that agreeableness had a significant and positive effect on satisfaction. Expectations about its utility and the possible noise had a positive effect on satisfaction. Expectations of lack of air showed a negative significant effect on satisfaction. Sociodemographics showed no significant effects. Our study confirmed the important impact of individuals' personality and expectations on satisfaction with the procedure. Moreover, it provides useful insights for developing consultations aimed at increasing the acceptability of the procedure.

Preliminary observations regarding the expectations, acceptability and satisfaction of whole-body MRI in self-referring asymptomatic subjects.

OBJECTIVE: To evaluate the satisfaction of asymptomatic subjects who self-referring Whole-Body Magnetic Resonance Imaging (WB-MRI) for early cancer diagnosis. METHODS: Subjects completed a pre-examination questionnaire, while waiting for their WB-MRI examination, recording demographics, expected discomfort, perceived knowledge and usefulness of the procedure and health risk perceptions, as well as a post-examination questionnaire, measuring discomfort experienced, acceptability and satisfaction with WB-MRI. We examined which factors influenced discomfort and satisfaction associated with WB-MRI. RESULTS: 65 asymptomatic subjects (median age 51; 29 females) completed the questionnaire. Before WB-MRI, 29% of subjects expected discomfort of some form with claustrophobia (27.7%) and exam duration (24.6%) being the most common concerns. Experienced discomfort due to shortness of breath was significantly lower than expected. This difference was significantly associated with the personal risk perception to get a disease (p = 0.01) and educational level (p = 0.002). More specifically, higher level of perceived personal risk of getting a disease and lower level of education were associated with higher expected than experienced discomfort. Similarly, experiencing less claustrophobia than expected was significantly associated with gender (p = 0.005) and more pronounced among females. A majority (83%) of subjects expressed high levels of satisfaction with WB-MRI for early cancer diagnosis and judged it more acceptable than other diagnostic exams. CONCLUSIONS: Asymptomatic subjects self-referring to WB-MRI for early cancer diagnosis showed high levels of satisfaction and acceptability with the examination. Nevertheless, a relevant proportion of participants reported some form of discomfort. Interestingly, participants with higher perceived personal risk to get a disease, lower education and females showed to expect higher discomfort than experienced. ADVANCES IN KNOWLEDGE: Scope exists for measures to assess expected feelings and develop personalized interventions to reduce the stress anticipated by individuals deciding to undergo WB-MRI for early cancer diagnosis.

'I didn't realise I was such a sausage': men's accounts of whole-body scanning, body image, and expected changes in health-related behaviours.

OBJECTIVE: Whole-body scanning is now available in stores to assist buyers in choosing well-fitting clothes. This study was designed to investigate men's accounts of scanning, body image and expectations of behaviour change. DESIGN: Ten men aged 18-39 years without histories of eating disorders or previous experience of whole-body scanning, took part in semi-structured interviews before and after scanning. Data were analysed using inductive thematic analysis. RESULTS: Pre-scan, men's body ideals were tall, slender and relatively muscular. Post-scan, seven reported looking shorter, fatter, thinner and/or less symmetrical than they hoped; three were pleasantly surprised by the images. Men were interested in scans as an objective view of their bodies and as a 'wake-up call' to motivate healthy behaviours. Five men intended to change their behaviour as a result of scanning, and repeat scanning was seen as a good way to monitor behavioural changes. Participants suggested that scanning may raise body concerns in other men, though downplayed impacts on their own body image. CONCLUSION: Whole-body scanning may encourage men to exercise and eat more healthily. However, men became more negative about their bodies as a result of seeing their body scans, so scanning needs to be carried out with supervision and support.

Investigating cancer patient acceptance of Whole Body MRI.

BACKGROUND: Whole Body magnetic resonance imaging (WB-MRI) enables early cancer detection, without exposing the patient to ionizing radiation. Our aim was to investigate patients' acceptance of WB-MRI as a procedure for cancer staging and follow up. MATERIALS AND METHODS: 135 oncologic subjects participated to the study. An ad hoc questionnaire was administered before and after WB-MRI, to assess patient's confidence and concerns about WB-MRI, psychological reactions, experience and perceived utility of the procedure. RESULTS: Before undergoing WB-MRI, about 58% of the patients were concerned for cancer progression outcome. 80.4% felt that they were given good information about the exam and the most informed group also perceived and higher level of utility of WB-MRI and no risk. Among people reporting discomfort with the exam (51.9%) the main reasons were noise and exam duration. Despite this, 80% of patients expressed high levels of satisfaction, and the majority (69%) judged WB-MRI more acceptable than other diagnostic exams. Patients who believed to have received more information before the exam rated their global satisfaction higher. CONCLUSION: Our results show that WB-MRI examinations were well-accepted and perceived with high levels of satisfaction by most patients. WB-MRI appears to be equally or more tolerable than other total body imaging modalities (e.g. PET, CT), especially if they receive enough information from the radiologist.

Perceived patient burden and acceptability of whole body MRI for staging lung and colorectal cancer; comparison with standard staging investigations.

OBJECTIVE: To evaluate perceived patient burden and acceptability of whole body MRI (WB-MRI) compared to standard staging investigations, and identify predictors of reduced tolerance. METHODS: Patients recruited to multicentre trials comparing WB-MRI with standard staging scans for lung and colorectal cancer were invited to complete two questionnaires: a baseline questionnaire at recruitment, measuring demographics, comorbidities, and distress; and a follow-up questionnaire after staging, measuring recovery time, comparative acceptability/satisfaction between WB-MRI and CT (colorectal cancer) and PET-CT (lung cancer), and perceived scan burden (scored 1, low; 7, high).  Results: 115 patients (median age 66.3 years; 67 males) completed follow up and 103 baseline questionnaires. 69 (63.9%) reported "immediate" recovery from WB-MRI and 73 (65.2%) judged it "very acceptable". Perceived WB-MRI burden was greater than for CT (p < 0.001) and PET-CT (p < 0.001). High distress and comorbidities were associated with greater WB-MRI burden in adjusted analyses, with deprivation only approaching significance (adjusted regression ß = 0.223, p = 0.025; ß = 0.191, p = 0.048; ß = -0.186, p = 0.059 respectively). Age (p = 0.535), gender (p = 0.389), ethnicity (p = 0.081) and cancer type (p = 0.201) were not predictive of WB-MRI burden. CONCLUSION:  WB-MRI is marginally less acceptable and more burdensome than standard scans, particularly for patients with pre-existing distress and comorbidities.  Advances in knowledge: This research shows that WB-MRI scan burden, although low, is higher than for current staging modalities among patients with suspected colorectal or lung cancer. Psychological and physical comorbidities adversely impact on patient experience of WB-MRI. Patients with high distress or comorbid illness may need additional support to undergo a WB-MRI.

'I think a little bit of a kick is sometimes what you need': Women's accounts of whole-body scanning and likely impact on health-related behaviours.

OBJECTIVE: This study was designed to investigate whether whole-body scanning might promote healthy eating and physical activity in women, and to explore the effects of scanning on body image. DESIGN: Fourteen women aged 22-45 years without histories of eating disorders or whole-body scanning took part in semi-structured interviews before and after scanning. Data were analysed using inductive thematic analysis. RESULTS: Scans did not look as expected, and participants expressed 'surprise' and 'shock'. Participants focused on perceived negative aspects of their bodies as revealed in scan images, and agreed that women with body concerns would find scans too 'real' and 'raw'. Eleven women who met UK Government physical activity and healthy eating guidelines reported that the scan provided additional motivation to maintain, and in nine cases to increase, those behaviours. Two women who neither exercised nor ate healthily would not increase physical activity or change their diets significantly following scanning. CONCLUSION: Whole-body scanning may enable maintenance or even acceleration of physical activity and healthy eating, but is unlikely to be useful in promoting initiation of these behaviours. Participants engaged in unhelpful body critique when viewing scans; scanning needs to be confined to contexts where support is provided, to avoid increasing body-related concerns.

Impact of whole-body MRI in a general population study.

This study examined the long-term impact of whole-body MRI and the disclosure of incidental findings on quality of life (QoL) and depressive symptoms in a general population cohort. Analyses were conducted among 4420 participants of the Study of Health in Pomerania SHIP-Trend cohort, of which 2188 received a whole-body MRI examination. A 2.5-year postal follow-up of SHIP-Trend (response: 86%) included the Short Form Health Survey (SF-12), based on which the Mental Health Component Summary Score (MCS), and Physical Health Component Summary Score (PCS) were computed. The Patient Health Questionnaire (PHQ-9) was applied to assess depressive symptoms. Generalized estimation equation models were used to assess intervention effects, and statistical weights were applied to account for selective attrition. MRI participants had higher levels of education and employment than nonparticipants. Mean QoL indicators differed little at baseline between MRI participants and nonparticipants. Intervention effects per year on depression and QoL were negligible in (1) MRI participants versus nonparticipants [PCS: unstandardized ß = -0.06 (95% CI -0.30 to 0.18); MCS: ß = -0.01 (95% CI -0.29 to 0.29); PHQ-9: 0.08 (-0.03 to 0.18)], and (2) MRI participants with a disclosed incidental finding versus those without [PCS: ß = -0.03 (-0.39 to 0.33); MCS: ß = -0.26 (95% CI -0.65 to 0.13); PHQ-9: 0.03 (-0.10 to 0.15)]. The body site of the finding had only minor effects on the course of our studied outcomes. Whole-body MRI can be implemented in a population-based study without long-term effects on QoL indicators and depressive symptoms. This does not exclude the possibility of effects on more subtle psychosocial outcomes, such as health concerns or health behaviour, all of which require further attention.

Effects of virtual human animation on emotion contagion in simulated inter-personal experiences.

We empirically examined the impact of virtual human animation on the emotional responses of participants in a medical virtual reality system for education in the signs and symptoms of patient deterioration. Participants were presented with one of two virtual human conditions in a between-subjects experiment, static (non-animated) and dynamic (animated). Our objective measures included the use of psycho-physical Electro Dermal Activity (EDA) sensors, and subjective measures inspired by social psychology research included the Differential Emotions Survey (DES IV) and Positive and Negative Affect Survey (PANAS). We analyzed the quantitative and qualitative measures associated with participants’ emotional state at four distinct time-steps in the simulated interpersonal experience as the virtual patient’s medical condition deteriorated. Results suggest that participants in the dynamic condition with animations exhibited a higher sense of co-presence and greater emotional response as compared to participants in the static condition, corresponding to the deterioration in the medical condition of the virtual patient. Negative affect of participants in the dynamic condition increased at a higher rate than for participants in the static condition. The virtual human animations elicited a stronger response in negative emotions such as anguish, fear, and anger as the virtual patient’s medical condition worsened.

Whole-body MRI vs. CT for staging lymphoma: patient experience.

OBJECTIVE: To assess and compare patient experience of whole-body magnetic resonance imaging (MRI) to that of computed tomography (CT) for staging newly diagnosed lymphoma. MATERIALS AND METHODS: A total of 36 patients with newly diagnosed lymphoma prospectively underwent whole-body MRI and CT for staging purposes. Patients were asked to fill in a short questionnaire with regard to the burden and experience of the examination on a Likert scale (range 1-4). Wilcoxon signed rank tests were used to determine statistically significant differences in patient (dis)comfort between the two examinations. RESULTS: Patients reported to be significantly (P=0.007) less worried before undergoing whole-body MRI compared to CT. Patients also experienced whole-body MRI as significantly (P=0.010) less unpleasant and felt significantly (P=0.003) better shortly after the scan. The necessary preparations before CT scanning (i.e. insertion of intravenous line, drinking of contrast fluid), which are not required for whole-body MRI, were reported to be a considerable burden. CONCLUSION: In this study in patients with newly diagnosed lymphoma, whole-body MRI was experienced as a more patient-friendly technique than CT.

Psychosocial consequences and severity of disclosed incidental findings from whole-body MRI in a general population study.

OBJECTIVES: Little is known about the psychosocial impact and subjective interpretation of communicated incide ntal findings from whole-body magnetic resonance imaging (wb-MRI). This was addressed with this general population study. METHODS: Data was based on the Study of Health in Pomerania (SHIP), Germany. SHIP comprised a 1.5-T wb-MRI examination. A postal survey was conducted among the first 471 participants, aged 23-84 years, who received a notification about incidental findings (response 86.0 %, n = 405). The severity of incidental findings was assessed from the participants' and radiologists' perspective. RESULTS: In total, 394 participants (97.3 %) wanted to learn about their health by undergoing wb-MRI. Strong distress while waiting for a potential notification of an incidental finding was reported by 40 participants (9.9 %), whereas 116 (28.6 %) reported moderate to severe psychological distress thereafter. Strong disagreement was noted between the subjective and radiological evaluation of the findings' severity (kappa = 0.02). Almost all participants (n = 389, 96.0 %) were very satisfied with their examination. CONCLUSIONS: Despite the high satisfaction of most participants, there were numerous adverse consequences concerning the communication of incidental findings and false expectations about the likely potential benefits of whole-body-MRI. KEY POINTS: • Disclosed incidental findings from MRI may lead to substantial psychosocial distress. • Subjective and radiological evaluations of incidental findings' severity differ strongly. • Disclosing incidental findings is strongly endorsed by study volunteers. • Study volunteers tend to have false expectations about potential benefits from MRI. • Minimizing stress in study volunteers should be a key aim in MRI research.

[Total body scan: struggle between emotion and science]. / 'Total body scan': strijd tussen gevoel en verstand.

In the late nineties of the last century, commercial screening centres started using CT and MRI technology to screen healthy people for the presence of asymptomatic tumours and cardiovascular diseases. Although this concept of screening is very appealing, research so far leads to doubts about its usefulness. The costs of assessing the significance of false positive findings in particular can be considerable and these are generally paid for by the general health insurance. More recently, these centres have been offering a broad screening package including prostate-specific antigen (PSA) and pulmonary and cardiac functioning tests. Here too, data on usefulness are lacking and, instead of offering useable medical advice, such screening activities could harm the health of the screened people.

Utilization and rationale for the implementation of total body (digital) photography as an adjunct screening measure for melanoma.

The primary objective of our study was to update the prevalence of total body photography (TBP) utilization and the rationale for its implementation as an adjunctive screening measure by academic dermatologists across the USA, and investigate the emergence of total body digital photography (TBDP). Our secondary objective was to further examine how TBP/TBDP is being incorporated into the dermatology screening examination in academic pigmented lesion clinics. A questionnaire was mailed to 113 dermatology departments across the USA. About 43% (49/113) of surveyed departments responded. TBP was used by 67% (33/49) of the respondents. Of these respondents, 33% (11/33) used TBDP alone, 33% (11/33) used TBDP in combination with nondigitally based TBP, and 33% (11/33) used nondigital TBP with print photos. The three most frequently cited reasons for the use of full-body baseline photographs were that they reduced patient anxiety, led to fewer biopsies, and helped to find melanoma early in the curable stage. Respondents who did not use full body baseline photographs cited logistical constraints as the number one reason, followed by perceived lack of utility. In conclusion, our study shows that there is a significant number of academic dermatologists using TBP/TBDP. However, this study also shows that there are conflicting beliefs among academic dermatologists concerning the efficacy of TBP/TBDP. At this point with a documented growing trend in utilization of TBP, more studies are needed to evaluate the efficacy of this screening adjunct to diagnose melanoma early and positively impact survival because of early diagnosis.
