Researchers used nuclear imaging to study how mice absorb radioactive iodine, finding that a dose five times higher than the FDA-recommended dosage is needed for effective protection. The team discovered that using this higher dose can improve image quality and reduce false-positive readings.
Researchers at JLab and College of W&M studied radiation blockers to enhance nuclear imaging accuracy. They found that higher doses of potassium iodide blocked radioactive iodine uptake better in mice. The study uses a unique medical imaging system and precise detectors, providing insights into the body's metabolism and thyroid function.
Drezek has been recognized by the Beckman Foundation for her research on novel optical molecular imaging technologies for early cancer detection. Her award includes a three-year $264,000 grant to develop and refine this technology.
The UK NHS telemedicine initiative has failed to deliver promised benefits, with integration issues and inadequate patient consultation hindering its success. New portable telecare systems for monitoring chronic illnesses are being developed but face similar challenges.
The researchers created nano-sized probes using emissive polymersomes that can optically image tissue structures deep below the skin, with potential to target multiple cancer cell-surface markers simultaneously. The probes use near-infrared light to produce a bright signal detectable through imaging systems.
A statistical model was developed to automatically determine heart contours from X-ray images, reducing time and variability in observer interpretations. This technology has been incorporated into a commercial software application used by physicians and surgeons to improve diagnosis and treatment of heart conditions.
A new esophageal capsule has been found to be as effective as traditional endoscopy in detecting Barrett's esophagus, a pre-cancerous condition. The study showed a high sensitivity of 97% and specificity of 100% in identifying esophageal abnormalities.
A perfect lens could improve electronic circuitry, fiberoptic communications, and medical imaging, but mathematical analysis shows it is not feasible. Researchers used rigorous math to demonstrate that a perfect lens would struggle with the concept of negative refraction.
The study found that CT scans for facial trauma reduced hospital costs by 22%, mainly due to time savings. This is because CT scans take only 10 seconds, while X-rays take 25 minutes, resulting in less room use and technologist time.
Researchers at Jefferson Lab are adapting detector technology to develop a new gene therapy technique for cystic fibrosis, which affects 30,000 Americans. The technology allows for successful imaging of gene transfer in mice, paving the way for clinical trials.
The study found that dedicated CT technology detected lower spine fractures in 36 patients, while plain radiographs only detected them in 28. Transverse process fractures were also identified more accurately on MDCT. The benefits of using MDCT include improved patient care and cost savings.
The study found that over half of the centers offering full-body scans were located on the east and west coasts, with California and New York having the largest concentrations. The researchers recommend stricter regulation to protect healthcare consumers from unregulated repeat exams and unwarranted expenditures.
A new microdialysis probe can detect cytokine markers indicating early infection or rejection responses to implants. This detection method aims to bioengineer the site for optimal device performance, ultimately benefiting public health and economic development.
Dr. Halas' nanoshell technology has the potential to revolutionize breast cancer detection and treatment by providing earlier diagnosis, increased imaging resolution, and real-time information about tumor cells. This innovative approach uses near infrared light to target and destroy tumors without harming healthy tissue.
Researchers demonstrate noninvasive microscopy scans producing images of diseased tissue at the cellular level, rivaling traditional histopathology methods. The technique uses natural fluorescence and multiphoton microscopy to enable optical biopsies on living animals or humans without surgical intervention.
A new study finds that diffusion-weighted MR imaging can detect stroke with high accuracy, outperforming traditional CT scans. The technique is 100% specific and 90% sensitive in identifying patients who have had a stroke.
A study of 33 patients found MR imaging to be more effective than ultrasound in diagnosing large lesions and precisely localizing paratesticular lesions. The use of MR imaging as a follow-up to sonography can reduce costs and recovery time associated with unnecessary biopsies or surgical intervention.
A researcher at the University of Toronto has developed a method to automatically remove the unsightly scarlet spots, known as red-eye, from digital images. The software isolates the reddened areas of the eyes and replaces them with natural eye color, providing a convenient solution for consumers.
Researchers at Rutgers-Newark are using electrical imaging to monitor the performance of permeable reactive barriers, which remove contaminants from groundwater. The study aims to improve the understanding of iron wall impacts and develop a tool for long-term monitoring of underground technologies.
Researchers at Johns Hopkins Medicine have developed a novel imaging technique to detect tiny tumors that cause a rare bone disorder. The method, which uses radioactive pentetreotide to identify tumor locations, has correctly pinpointed tumors in five of seven patients with oncogenic osteomalacia.
The Keck Foundation is funding a $750,000 grant to develop a 3D fusion microscope at Northeastern University. The instrument will enable three-dimensional imaging of biological specimens using five advanced technologies, with applications in embryonic development and spinal cord injury research.
