INTRODUCTION U.S. Army Special Forces Medics (18Ds) operate in austere environments where decisions regarding patient management may be limited by available resources. Portable ultrasound may allow for the detection of fractures in environments where other imaging modalities such as radiography are not readily available or practical. OBJECTIVE We used a simulation training model for the ultra...

Although musculoskeletal ultrasound (MSUS) has emerged as an indispensible tool among physicians involved in musculoskeletal medicine in the last two decades, only recently has it become more attractive to pediatric rheumatologists. Thereafter, the use of MSUS in pediatric rheumatology has started to increase. Yet, an ever-growing body of literature shows parity and even superiority of MSUS whe...

Optical mapping of excitation dynamically tracks electrical waves travelling through cardiac or brain tissue by the use of fluorescent dyes. There are several characteristics that set optical mapping apart from other imaging modalities: dynamically changing signals requiring short exposure times, dim fluorescence demanding sensitive sensors and wide fields of view (low magnification) resulting ...

PURPOSE To determine the potential application of contrast-enhanced ultrasound in the characterisation of focal liver lesions encountered in radiological practice at a district general hospital. MATERIALS & METHODS Retrospective analysis of 68 sequential patients undergoing contrast-enhanced ultrasound (CEUS) of liver. All patients were referred for CEUS following identification of 1 or more ...

The continued development of hardware and associated image processing techniques for quantitative phase microscopy has allowed superior phase data to be acquired that readily shows dynamic optical volume changes and enables particle tracking. Recent efforts have focused on tying phase data and associated metrics to cell morphology. One challenge in measuring biological objects using interferome...

Sixteen-channel coil dedicated for small animal MRI. An array comprises 8 5-cm-circular coils (a). The 16-channel coil has 2 sets of 8-array coils in the upper and lower parts (b). A white bar on the top is used to adjust the...

background: to date, several imaging techniques to track stem cells are used such as positron emission tomography (pet), single photon emission computed tomography (spect), bioluminescence imaging (bli), fluorescence imaging, ct scan and magnetic resonance imaging (mri). although, overall sensitivity of mri compared to spect and bioluminescence techniques are lower, but due to high spatial reso...
