Multivessel peripheral revascularization for acute stroke intervention: successful M2 bifurcation stenting and the growi...

Ramsey D. Badawi Patel, Ra Reilly, Jp

Published in Catheterization and Cardiovascular Interventions

A comprehensive endovascular skill set is desirable and key to successful intervention in the patient with complex cardiovascular disease. Acute stroke intervention is the next frontier for the endovascular specialist. We report a case of acute stroke intervention in a patient with severe peripheral vascular disease performed by interventional card...

Spatial distortion correction and crystal identification for MRI-compatible position-sensitive avalanche photodiode-base...

Abhijit Chaudhari Joshi, Aa Wu, Y Leahy, Rm Cherry, Sr Ramsey D. Badawi

Published in IEEE Transactions on Nuclear Science

Position-sensitive avalanche photodiodes (PSAPDs) are gaining widespread acceptance in modern PET scanner designs, and owing to their relative insensitivity to magnetic fields, especially in those that are MRI-compatible. Flood histograms in PET scanners are used to determine the crystal of annihilation photon interaction and hence, for detector ch...

A comparison of normalization effects on three whole-body cylindrical 3D PET systems.

Ramsey D. Badawi Ferreira, Nc Kohlmyer, Sg Dahlbom, M Marsden, Pk Lewellen, Tk

Published in Physics in Medicine and Biology

Normalization coefficients in three-dimensional positron emission tomography (3D PET) are affected by parameters such as camera geometry and the design and arrangement of the block detectors. In this work, normalization components for three whole-body 3D-capable tomographs (the GE Advance, the Siemens/CTI962/HR+ and the Siemens/CTI951R) are compare...

Impella 2.5 assisted balloon aortic valvuloplasty and percutaneous coronary intervention as a bridge to heart transplant...

Ramsey D. Badawi Grise, Ma Thornton, Sn

Published in The Journal of invasive cardiology

Percutaneous left ventricular assist device (pLVAD) utilization is increasing as the potential applications expand. We report a case of high-risk balloon aortic valvuloplasty and percutaneous coronary intervention using the Impella 2.5 pLVAD in a patient with severely depressed left ventricular function as a bridge to heart transplantation.

Use of positron emission tomography in oncology and its potential role to assess response to imatinib mesylate therapy i...

Van Den Abbeele, Ad Ramsey D. Badawi

Published in European Journal of Cancer

The reliability of established anatomical imaging techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI), is compromised in following response to certain types of treatment if metabolic improvement occurs before morphologic change is apparent. Thus, traditional imaging techniques cannot discriminate early tumor response b...

A technique for hemostasis and closure after percutaneous aortic valve replacement.

Ramsey D. Badawi

Published in Catheterization and Cardiovascular Interventions

Access closure is the key to successful retrograde percutaneous aortic valve replacement. It requires large-bore femoral arterial access (18-28F) which most operators manage with surgical access and closure under general anesthesia. We report a case example of how, using our center s peripheral interventional experience, we have developed a techniq...

Radiation risks to personnel and public during the treatment of malignant glioma using interstitial brachytherapy.

Baldock, C Hughes, Sw Sofat, A Batchelor, S Ramsey D. Badawi

Published in British Journal of Radiology

125I seeds are used in brachytherapy for the treatment of malignant gliomas. The use of such radioactive sources is associated with a certain radiological hazard to both personnel and members of the public. This hazard should be quantified so that the ALARA principle of radiological protection may be implemented satisfactorily. A study was undertak...

Nontyphoidal salmonella pericarditis: a case of Salmonella typhimurium phage type 2 pericarditis.

Using global illumination in volume visualization of rheumatoid arthritis CT data.

Zheng, L Abhijit Chaudhari Ramsey D. Badawi Ma, Kl

Published in IEEE Computer Graphics and Applications

Proper lighting in rendering is essential for visualizing 3D objects, but most visualization software tools still employ simple lighting models. The advent of hardware-accelerated advanced lighting suggests that volume visualization can be truly usable for clinical work. Researchers studied how volume rendering incorporating global illumination imp...
