PURPOSE The authors present initial progress toward a clinically compatible x-ray phase contrast CT system, using glancing-angle x-ray grating interferometry to provide high contrast soft tissue images at estimated by computer simulation dose levels comparable to conventional absorption based CT. METHODS DPC-CT scans of a joint phantom and of soft tissues were performed in order to answer sev...

INTRODUCTION Sprained ankle is a very common injury in children. Proper treatment of ligament injuries enables full recovery. X-ray and US examinations are commonly available diagnostic methods. MATERIAL AND METHODS Two hundred and six children (113 girls and 93 boys, mean age 10.6) with recent ankle joint sprain (up to 7 days of injury) were subject to a retrospective analysis. All patients ...

A 39-year-old male with a history of cocaine abuse presents to the emergency room with pain in the right leg and fever (39oC) 6 days after injecting himself in the thigh with midazolam pills diluted in tap water to control symptoms of withdrawal. Physical examination revealed rubor, swelling and tenderness of the thigh without crepitation, suggestive of cellulitis. Laboratory findings consisted...

X-ray computed tomography has become an important tool for studying the microstructures of biological soft tissues, such as ligaments and tendons. Due to the low X-ray attenuation of such tissues, chemical contrast agents are often necessary to enhance contrast during scanning. In this article, the effects of using three different contrast agents--iodine potassium iodide solution, phosphotungst...

A young child presented with intermittent bowel obstruction. The abdominal X-ray was not closely examined, and a contrast study was performed that demonstrated multiple tubular filling defects indicative of worms. The patient was treated accordingly. Reviewing the abdominal X-ray demonstrated numerous serpigenous, tubular, soft-tissue densities in gas-filled bowel loops.

REAL-TIME, 3-DIMENSIONAL TRANSESOPHAGEAL ECHOCARDIOGRAPHY (RT 3D TEE) IS NOW USED ROUTINELY IN CONJUNCTION with x-ray fluoroscopy to guide percutaneous structural heart disease (SHD) interventions. Unlike fluoroscopy, RT 3D TEE provides excellent detail of 3D anatomy and soft tissue structures, and provides “live” intraprocedure guidance. A novel 3D echo-x-ray navigation system that successfully

Using dedicated contrast agents high-quality X-ray imaging of soft tissue structures with isotropic micrometre resolution has become feasible. This technique is frequently titled as virtual histology as it allows production of slices of tissue without destroying the sample. The use of contrast agents is, however, often an irreversible time-consuming procedure and despite the non-destructive pri...

Dual-energy (DE) breast x-ray imaging involves acquiring images using a lowand high-energy x-ray spectral pair. These images are then subtracted with a weighting factor that eliminates the soft-tissue signal variation present in the breast leaving only contrast that is attributed to an exogenous imaging agent. We have previously demonstrated the potential for silver (Ag) as a contrast material ...
