Machine learning and magnetic resonance imaging: Differentiating benign from malignant osseous tumors.

Radiomics and machine learning applied to the isolated cartilaginous bone lesion on magnetic resonance imaging (MRI) is increasingly useful to distinguish malignant versus benign bone lesions, to determine whether repetitive imaging over time, to determine dynamic expansion, or immediate excisional biopsy are indicated.

Sonoelastography: A powerful technique in musculoskeletal imaging.

Sonoelastography is a powerful method available to observe the musculoskeletal system, and appears particularly valuable in detecting early tendinopathies, pursuing complaints of localized musculoskeletal pain, analyzing soft tissue masses, and research applications in musculoskeletal medicine.

Intralesional Injection of Triamcinolone Acetonide for Subcutaneous Lipoma causing Musculoskeletal and Neurologic Symptoms.

Benign subcutaneous lipomas can cause musculoskeletal pain and nerve impingement. We hypothesized that the potent lipolytic and atrophic effect of 40mg/mL triamcinolone acetonide would atrophy symptomatic lipomas so surgical excision could be avoided. This was a cohort study.

Outcomes and cost-effectiveness of ultrasound-guided injection of the trochanteric bursa.

We hypothesized that ultrasound (US) guidance improves outcomes of corticosteroid injection of trochanteric bursitis. 40 patients with greater trochanteric pain syndrome defined by pain to palpation over the trochanteric bursa were randomized to injection with 5 ml of 1% lidocaine and 80 mg of methylprednisolone using (1) conventional anatomic landmark palpation guidance or (2) US guidance. Procedural pain (Visual Analogue Pain Scale), pain at outcome (2 weeks and 6 months), therapeutic duration, time-to-next intervention, and costs were determined.

Highly controlled vascular syringes for pericardiocentesis.

Objectives: The present study determined the utility and needle control characteristics of highly controlled vascular syringes for image-guided pericardiocentesis.

Background: Vascular syringes have been integrated into invasive cardiovascular procedures with improved patient safety, but to date have not been used in pericardiocentesis. To address this issue, we determined the method of use of vascular syringes for pericardiocentesis.
