Effectiveness of educational videos on patient's preparation for diagnostic procedures: Systematic review and Meta-Analysis.

Although diagnostic procedures are crucial for secondary prevention and patient disease control, they often trigger fear and anxiety. These reactions highlight the need to adopt effective interventions to improve patients' experience and satisfaction. Recently, educational videos have been employed in preparing diagnostic procedures; however, there is no integrated understanding of their effects.

3D Printing of Abdominal Immobilization Masks for Therapeutics: Dosimetric, Mechanical and Financial Analysis.

Molding immobilization masks is a time-consuming process, strongly dependent on the healthcare professional, and potentially uncomfortable for the patient. Thus, an alternative sustainable automated production process is proposed for abdominal masks, using fused deposition modelling (FDM) 3D printing with polylactic acid (PLA). Radiological properties of PLA were evaluated by submitting a set of PLA plates to photon beam radiation, while estimations of their mechanical characteristics were assessed through numerical simulation.

Cancer Patient Experience in a Nuclear Medicine Department: Comparison Between Bone Scintigraphy and F-FDG PET/CT.

Our objective was to assess the anxiety level in cancer patients undergoing nuclear medicine exams and to identify how professionals can improve patient experience. In total, 94 patients undergoing Tc-hydroxymethylene diphosphonate (Tc-HDP) bone scintigraphy (BS) or F-FDG PET/CT completed 2 scan-experience questionnaires and the Spielberger State Anxiety Inventory (STAI-S) before the scan and after image acquisition. Before the exam, the mean anxiety levels were higher for the Tc-HDP BS group than for the F-FDG PET/CT group.

Anxiety in Cancer Patients during F-FDG PET/CT Low Dose: A Comparison of Anxiety Levels before and after Imaging Studies.

. Assessing the level of anxiety in oncology patients who underwent F-FDG PET/CT low dose scan and identifying the main reasons that generate anxiety. .

Value of a Lower-Limb Immobilization Device for Optimization of SPECT/CT Image Fusion.

Unlabelled: The foot and the ankle are small structures commonly affected by disorders, and their complex anatomy represents a significant diagnostic challenge. By providing information on anatomic and bone structure that cannot be obtained from functional imaging, SPECT/CT image fusion can be particularly useful in increasing diagnostic certainty about bone pathology. However, because of the lengthy duration of a SPECT acquisition, a patient's involuntary movements may lead to misalignment between SPECT and CT images.

Social support of low-income Brazilian mothers related to time to completion of childhood vaccinations.

Our study objective was to examine how maternal social support and depressive symptoms are associated with time to completion of childhood vaccinations. We used cross-sectional data from 582 randomly-selected, low-income Brazilian children. Adjusted Cox Proportional Hazard models were used to estimate time to completing the first three recommended oral polio and diphtheria, pertussis and tetanus (DPT) vaccinations as well as their booster doses.

Influence of reconstruction parameters during filtered backprojection and ordered-subset expectation maximization in the measurement of the left-ventricular volumes and function during gated SPECT.

Unlabelled: A crucial method for investigating patients with coronary artery disease (CAD) is the calculation of the left ventricular ejection fraction (LVEF). It is, consequently, imperative to precisely estimate the value of LVEF--a process that can be done with myocardial perfusion scintigraphy. Therefore, the present study aimed to establish and compare the estimation performance of the quantitative parameters of the reconstruction methods filtered backprojection (FBP) and ordered-subset expectation maximization (OSEM).
