A review of virtual reality in radiology.

Virtual reality (VR) is not new to the field of medicine or radiology but has grown exponentially in recent years. Exploration of VR in medicine to augment educational experiences and aid in procedural training began in the 1990s. Surgeons have benefited from VR, both for training and planning purposes.

Preliminary investigation: Feasibility study of a virtual reality breast biopsy simulation.

Rationale And Objectives: Ultrasound-guided breast biopsies are the most frequently performed imaging-guided breast procedures. During training, learners may lack exposure due to limited volume and sensitive anatomy. Current simulation training often involves the use of manufactured or homemade (chicken or turkey breast) phantoms.

Utilizing a Virtual Reality Matrix in Medical Education.

Virtual reality (VR) is an emerging technology that has demonstrated incredible value within medical education. However, medical institutions adopting VR as a learning tool need to ensure that the immersive technology product they pick possesses standard usability criteria. The current literature is limited in defining what specific criteria institutions should look for, or how to select between various VR products.

Virtual Reality Simulation-Based Training in Image-Guided Breast Intervention in Low- and Middle-Income Countries.

Online education has revolutionized global radiology education for low- and middle-income countries (LMICs). However, procedures requiring hands-on training, such as breast biopsies, are primarily taught through in-person sessions and patient interaction. Virtual reality (VR) offers an immersive way to simulate these sessions remotely.

Ultrafast MR imaging findings of 2 different subtypes in a male patient with bilateral breast cancer.

Bilateral breast cancer in males is an exceedingly rare diagnosis. In this case report, we will discuss the ultrafast sequence findings of a bilateral male breast cancer with different subtypes on his staging dynamic contrast enhanced (DCE) MRI with ultrafast technique. A 94-year-old male presented with bilateral palpable complaints in his breasts.

Obesity-induced Endothelial Dysfunction is Prevented by Neutrophil Extracellular Trap Inhibition.

Endothelial dysfunction precedes atherosclerosis and may constitute a critical link between obesity-related inflammation and cardiovascular disease. Neutrophil extracellular traps (NETs) have been shown to promote vascular damage in murine models of autoimmune disease and atherosclerosis. The impact of NETs towards endothelial dysfunction associated with obesity is unknown.

Angiotensin II-induced Hypertension is Reduced by Deficiency of P-selectin Glycoprotein Ligand-1.

Identification of inflammatory mediators that regulate the vascular response to vasopressor molecules may aid in the development of novel therapeutic agents to treat or prevent hypertensive vascular diseases. Leukocytes have recently been shown to be capable of modifying blood pressure responses to vasopressor molecules. The purpose of this study was to test the hypothesis that deficiency of the leukocyte ligand, Psgl-1, would reduce the pressor response to angiotensin II (Ang II).

Proprotein convertase subtilisin/kexin type 9 (PCSK9) Deficiency is Protective Against Venous Thrombosis in Mice.

The effect of lipid lowering on the incidence of deep venous thrombosis (DVT) is controversial. The purpose of this study was to determine the effect of proprotein convertase subtilisin/kexin type 9 (PCSK9) deficiency on development of DVT in mice. Pcsk9 deficient (pcsk9 ) and wild-type (WT) littermates underwent partial inferior vena cava (IVC) ligation to induce venous thrombosis.

Hematopoietic Deficiency of miR-223 Attenuates Thrombosis in Response to Photochemical Injury in Mice.

Some studies have shown that levels of MicroRNA (miR)-223 derived from platelets in the plasma are reduced following inhibition of platelet function, while others have shown a correlation between low plasma miR-223 and high on-treatment platelet reactivity. The present study seeks to investigate the role of miR-223 in arterial thrombosis. A model of photochemical-induced carotid thrombosis was applied to miR-223 deficient mice and littermate (WT) controls.

Psgl-1 Deficiency is Protective against Stroke in a Murine Model of Lupus.

Systemic lupus erythematosus (SLE) is associated with an elevated risk of vascular complications, including premature stroke. Therapies targeting leukocyte recruitment may be beneficial in reducing vascular complications associated with SLE. Lupus was induced in female wild-type (WT) and P-selectin glycoprotein ligand-1 deficient (Psgl-1(-/-)) mice with pristane.

Renal denervation attenuates progression of atherosclerosis in apolipoprotein E-deficient mice independent of blood pressure lowering.

The renal autonomic nervous system may contribute to hypertension and vascular disease. Although the effects of renal artery denervation on blood pressure lowering are controversial, there may be other beneficial vascular effects independent of blood pressure lowering. Bilateral renal denervation (RDN) or sham operation (SO) was performed in 14-week-old male apolipoprotein E-deficient mice on a Western diet starting at 10 weeks of age.
