Effect of an Artificial Intelligence Decision Support Tool on Palliative Care Referral in Hospitalized Patients: A Randomized Clinical Trial.

Context: Palliative care services are commonly provided to hospitalized patients, but accurately predicting who needs them remains a challenge.

Objectives: To assess the effectiveness on clinical outcomes of an artificial intelligence (AI)/machine learning (ML) decision support tool for predicting patient need for palliative care services in the hospital.

Methods: The study design was a pragmatic, cluster-randomized, stepped-wedge clinical trial in 12 nursing units at two hospitals over a 15-month period between August 19, 2019, and November 17, 2020.

Measuring Glucose Uptake in Primary Invasive Breast Cancer Using Simultaneous Time-of-Flight Breast PET/MRI: A Method Comparison Study with Prone PET/CT.

Purpose: To compare the measurement of glucose uptake in primary invasive breast cancer using simultaneous, time-of-flight breast PET/MRI with prone time-of-flight PET/CT.

Materials And Methods: In this prospective study, women with biopsy-proven invasive breast cancer undergoing preoperative breast MRI from 2016 to 2018 were eligible. Participants who had fasted underwent prone PET/CT of the breasts approximately 60 minutes after injection of 370 MBq (10 mCi) fluorine 18 fluorodeoxyglucose (F-FDG) followed by prone PET/MRI using standard clinical breast MRI sequences performed simultaneously with PET acquisition.

Review of breast augmentation and reconstruction for the radiologist with emphasis on MRI.

It is imperative to continue screening for breast cancer and/or detect tumor recurrence in patients after they have undergone breast augmentation or reconstruction. As there is an increasing role for both screening and diagnostic imaging of the post-operative breast, it is important for the radiologist to be familiar with the commonly performed surgical techniques in breast augmentation and reconstruction. Imaging of the augmented and reconstructed breast, as well as complications, will be reviewed with a focus on Magnetic Resonance Imaging (MRI).

Blood Pool Contrast-enhanced Magnetic Resonance Angiography with Correlation to Digital Subtraction Angiography: A Pictorial Review.

Magnetic resonance angiography (MRA) provides noninvasive visualization of the vascular supply of soft tissue masses and vascular pathology, without harmful radiation. This is important for planning an endovascular intervention, and helps to evaluate the efficiency and effectiveness of the treatment. MRA with conventional extracellular contrast agents relies on accurate contrast bolus timing, limiting the imaging window to first-pass arterial phase.

Efficacy of Arnica montana D4 for healing of wounds after Hallux valgus surgery compared to diclofenac.

Objective: This study was undertaken to answer the question: "Is Arnica D4 as efficacious as diclofenac in relation to symptoms and wound healing after foot surgery?"

Methods: In this randomized double-blinded, parallel-group study (GCP-standard), the efficacy of Arnica D4 10 pillules (taken orally, 3 times per day) and diclofenac sodium, 50 mg (taken orally, 3 times per day) were investigated for equivalence in 88 patients 4 days after hallux valgus surgery. Outcome parameters were (1) postoperative irritation, (2) patient mobility, (3) rated pain, and (4) use of analgesics. The hierarchic equivalence test based on one-sided Wilcoxon-Mann-Whitney-U confidence intervals (CIs) was used.
