Impact of Pain Education on Pain Relief in Oncological Patients: A Narrative Review of Systematic Reviews and Meta-Analyses.

Pain is a complex and burdensome symptom frequently experienced by oncological patients. Despite increased attention from healthcare providers and novel approaches, pain remains undertreated and prevalent in this patient population. Programs of patient education about pain (pain education, PE) have been proposed as a potential method to enhance pain management.

Feasibility of Multiparameter MRI-Guided Percutaneous Biopsy for Central Lung Lesions With Atelectasis.

Objective: To prospectively evaluate the feasibility, accuracy, and safety of multiparameter MRI-guided percutaneous biopsy using a 1T open MRI scanner for evaluating suspicious centrally located lung lesions with associated post-obstructive atelectasis.

Materials And Methods: In this single-center study, MRI-guided percutaneous coaxial cutting biopsy was performed for 107 suspicious central lung lesions with associated post-obstructive atelectasis in 107 patients between July 2015 and December 2020. A fast T2-weighted imaging (T2WI)-turbo spin echo (TSE) sequence and an enhanced fast T1-weighted imaging (T1WI)-TSE sequence were used to identify, localize, and biopsy lung lesions, and diffusion-weighted imaging (DWI) was used as a supplementary sequence for identifying the lesion location.

Assessing blood flow in uterine fibroids using intravoxel incoherent motion imaging compared with dynamic contrast-enhanced MRI.

To assess the utility of IVIM parameters in evaluating uterine fibroid blood flow compared to dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) derived blood flow. Sixteen premenopausal women with uterine fibroids were enrolled in this prospective study. Pelvic MRI scans were obtained for each subject, both with and without continuous intravenous infusion of oxytocin, known to decrease significantly uterine fibroid blood flow, to assess the changes in blood flow of uterine fibroids.

Histological findings in resected leiomyomas following MR-HIFU treatment, single-institution data from seven patients with unfavorable focal therapy.

Purpose: Magnetic resonance - high-intensity focused ultrasound (MR-HIFU) is a noninvasive treatment option for symptomatic uterine leiomyomas. Currently, pretreatment MRI is used to assess tissue characteristics and predict the most likely therapeutic response for individual patients. However, these predictions still entail significant uncertainties.

The role of co-occurring insomnia and mental distress in the association between lumbar disc degeneration and low back pain related disability.

Background: Lumbar disc degeneration (LDD) is associated with low back pain (LBP). Although both insomnia and mental distress appear to influence the pain experience, their role in the association between LDD and LBP is uncertain. Our objective was to investigate the role of co-occurring insomnia and mental distress in the association between LDD and LBP-related disability.

Deep learning prediction of non-perfused volume without contrast agents during prostate ablation therapy.

Unlabelled: The non-perfused volume (NPV) is an important indicator of treatment success immediately after prostate ablation. However, visualization of the NPV first requires an injection of MRI contrast agents into the bloodstream, which has many downsides. Purpose of this study was to develop a deep learning model capable of predicting the NPV immediately after prostate ablation therapy without the need for MRI contrast agents.

Factors Influencing the Adoption of Magnetic Resonance-Guided High-Intensity Focused Ultrasound for Painful Bone Metastases in Europe, A Group Concept Mapping Study.

Magnetic resonance imaging-guided high-intensity focused ultrasound (MR-HIFU) is an innovative treatment for patients with painful bone metastases. The adoption of MR-HIFU will be influenced by several factors beyond its effectiveness. To identify contextual factors affecting the adoption of MR-HIFU, we conducted a group concept mapping (GCM) study in four European countries.

Focused Ultrasound and RadioTHERapy for non-invasive palliative pain treatment in patients with bone metastasis: a study protocol for the three armed randomized controlled FURTHER trial.

Background: Cancer-induced bone pain (CIBP), caused by bone metastases, is a common complication of cancer and strongly impairs quality of life (QoL). External beam radiotherapy (EBRT) is the current standard of care for treatment of CIBP. However, approximately 45% of patients have no adequate pain response after EBRT.

Evolving imaging methods of prostate cancer and the emergence of magnetic resonance imaging guided ablation techniques.

Established therapies for prostate cancer (PCa), surgery and radiotherapy, treat the entire gland regardless of the location of the cancerous lesion within the prostate. Although effective, these methods include a significant risk of worsening genitourinary outcomes. Targeted image-guided cancer therapy has gained acceptance through improved PCa detection, localization, and characterization by magnetic resonance imaging (MRI).

Fiducial markers and their impact on ablation outcome for patients treated with MR-guided transurethral ablation (TULSA): a retrospective technical analysis.

Objectives: Fiducial markers improve accuracy in external beam radiation therapy (EBRT) for treatment of prostate cancer (PCa). However, many patients recur after EBRT necessitating additional treatment, such as MR-guided transurethral ultrasound ablation (TULSA). Residual markers may compromise TULSA through ultrasound field distortions and generation of local susceptibility artifacts.
