INTRODUCTION Burkitt's lymphoma accounts for approximately 25% of lymphomas diagnosed in children of developmental age. The tumor is localized mainly in the intestine (usually in the ileocecal region), mesenteric lymph nodes and extraperitoneal space. The clinical symptoms are non-specific and include: abdominal pain, vomiting, gastrointestinal bleeding, and acute abdomen suggesting appendiciti...

Damage induced in polymer composites by various impacts must be evaluated to predict a component's post-impact strength and residual lifetime, especially when impacts occur in structures related to human safety (in aircraft, for example). X-ray tomography is the conventional standard to study an internal structure with high resolution. However, it is of little use when the impacted area cannot ...

Introduction/Purpose Most image-guided interventions such as biopsies or tumor ablations can be readily performed under CT or ultrasound guidance. MRI may be indicated whenever a suspect lesion can not reliably be visualized with these imaging modalities [1]. In a standard 1.5T MRI scanner, however, the remaining space is practically too small to handle an instrument inside the bore. Freehand b...

The rapid growth in information and communication technologies has advances the medical data management systems immensely. In this regard, many different techniques and also the advanced equipment like Magnetic Resonance Imaging (MRI) Scanner, Computer Tomography (CT) scanner, Positron Emission of Tomography (PET), mammography, ultrasound, radiography etc. are used. Nowadays there is a rise of ...

Our aim was to assess the feasibility and accuracy of contrast-enhanced ultrasound (CEUS) of the breast with SonoVue microbubbles for pre-operative size measurement of invasive breast carcinomas. Seven patients diagnosed with nine invasive breast carcinomas prospectively underwent gray-scale ultrasound and CEUS of the breast according to a standardized protocol. CEUS of the breast was performed...

Ultrasound elastography is a promising imaging technique that can assist in diagnosis of thyroid cancer. However, the complexity of the tissue movements under freehand compression requires the use of a parametric displacement model and a specific estimation method adapted to sub-pixel motion. Therefore, the aim of this study was to develop a motion estimation method for ultrasound elastography ...

INTRODUCTION TO THE PROBLEM Muhimbili Orthopaedic Institute (MOI) is a public, academic tertiary care referral center in Dar es Salaam, Tanzania, East Africa. MOI is the main referral center for orthopedic and neurosurgical patients in Tanzania. In July 2014, the Radiology Department at MOI consisted of two attending radiologists, 10 technologists, and three IT staff with imaging capabilities o...

PURPOSE Voltage-based device-tracking (VDT) systems are commonly used for tracking invasive devices in electrophysiological cardiac-arrhythmia therapy. During electrophysiological procedures, electro-anatomic mapping workstations provide guidance by integrating VDT location and intracardiac electrocardiogram information with X-ray, computerized tomography, ultrasound, and MR images. MR assists ...
