Applications of gold nanoparticles for medical imaging
Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...
متن کاملMedical emergencies in medical imaging.
Sending inpatients to the medical imaging department is sometimes tantamount to discharging them from hospital for hours at a time. Consider, for example, a patient with an unexplained acute abdomen where an urgent CT scan is indicated. Patient transport, logistical delays and the procedure itself may lead to gaps in monitoring vital signs, providing intravenous fluids and administering medicat...
متن کاملMedical Imaging
Over the past fifty years the processes and techniques of medical imaging have undergone a veritable explosion, calling into service increasingly sophisticated mathematical tools. Mathematics provides a language to describe the measurement processes that lead, eventually, to algorithms for turning the raw data into high-quality images. There are four principal modalities in wide application tod...
متن کاملMedical imaging Ultrasound imaging systems
By transmitting acoustic energy into the body and receiving and processing the returning reflections, phased-array ultrasound systems can generate images of internal organs and structures, map blood flow and tissue motion, and provide highly accurate blood velocity information. Historically, the large number of high-performance phased-array transmitters and receivers required to implement these...
