Background: The rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. Materials and Methods: The system is composed of a micro positron emission tomography (mPET), 7T magnetic resonance imaging (MRI), and a customized MRI-compatible foc...
Twelve left camel forelimbs were collected, and ultrasonography was performed at five different levels around the metacarpal region. Limbs were then cut in the transverse plane at levels corresponding to the ultrasound images. Transverse and sagittal plane images were taken at each of the five levels, keeping all ultrasound imaging factors constant. Echogenicity, diameter, width and cross secti...
the most common soft tissue tumors during infancy and childhood are vascular lesions. although the vast majority of these lesions have typical clinical features and do not require any further exam, but sometimes atypical superficial or deeply located lesions need complementary studies to be diagnosed and classified. in that way it is also very important to exclude very less common malignant sof...
C onsiderable attention is currently being focused on the development of intravascular and intracardiac ultrasound imaging.1-4 Variously termed as "ultrasound angioscopy," "intravascular ultrasound imaging," or "intraluminal ultrasound imaging," this technique basically refers to the imaging modality of visualizing blood vessels and cardiac structures by an ultrasound transducer placed at the t...
