Experience With An Ultrasound Donation Program In A Low-Income Country, Michelle Hershman, Melody Hershman, Yamile Blain, Marie Evelyne Moise, Natasha Monchil, Amy A. Walters, Berndt P. Schmit

Journal of Global Radiology

Increasing radiology capacity in low-income countries (LIC) can improve clinicians’ access to diagnostic imaging tools and improve patient care. Ultrasound (US) is important in LIC due to its lower cost compared to that of CT or MRI scans and its excellent diagnostic ability. The relative portability of the equipment makes it ideal for donation by charitable organizations. We describe our experience as a radiology-capacity-focused charity working with the Haitian healthcare system and propose strategies to increase ultrasound capacity in other poor countries.

Radiopharmaceutical Validation For Clinical Use, Charles A. Kunos, Rodney Howells, Aman Chauhan, Zin W. Myint, Mark E. Bernard, Riham H. El Khouli, Jacek Capala

Internal Medicine Faculty Publications

Radiopharmaceuticals are reemerging as attractive anticancer agents, but there are no universally adopted guidelines or standardized procedures for evaluating agent validity before early-phase trial implementation. To validate a radiopharmaceutical, it is desirous for the radiopharmaceutical to be specific, selective, and deliverable against tumors of a given, molecularly defined cancer for which it is intended to treat. In this article, we discuss four levels of evidence—target antigen immunohistochemistry, in vitro and in vivo preclinical experiments, animal biodistribution and dosimetry studies, and first-in-human microdose biodistribution studies—that might be used to justify oncology therapeutic radiopharmaceuticals in a drug-development sequence involving early-phase ...

Image Guided Central Venous Catheter Placement, Nurullah Dogan, Mustafa Gok, Demet Gunduz

Health Sciences

Nowadays, central venous catheters (CVCs) are widely used medical tools for patients with chronic diseases or patients following in intensive care units (ICU), both for treatment and follow-up (drugs, fluids, blood and blood products, hemodynamic monitoring, etc.). With new drugs and treatment methods, demand for CVCs is increasing accordingly. While it was applied with landmark technique by only surgical departments for many years, it has been used by interventional radiologists under the guidance of imaging methods since 1990s. Due to the low rates of perioperative and early complications and the short duration of the procedure, imaging-guided CVC implantation has been ...

A Concise Review Of The Multimodality Imaging Features Of Renal Cell Carcinoma, Ali Morshid, Elif S. Duran, Woongsoon J. Choi, Cihan Duran

School of Medicine Publications and Presentations

The evaluation of renal cell carcinoma (RCC) is routinely performed using the multimodality imaging approach, including ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). Ultrasonography is the most frequently used imaging modality for the initial diagnosis of renal masses. The modality of choice for the characterization of the renal mass is multiphasic CT. Recent advances in CT technology have led to its widespread use as a powerful tool for preoperative planning, reducing the need for catheter angiography for the evaluation of vascular invasion. CT is also the standard imaging modality for staging and follow-up. MRI ...

Radiology request forms are the basis of communication between referring physicians and radiologists. These are the sole documents on the basis of which a justification to carry out a radiological procedure is carried out. However, across the globe, there is a problem of inadequately filled radiology request forms. Several interventions like standardization and the use of technology have been proposed worldwide to overcome the shortcomings of inadequately filled radiology request forms. We carried out a two-phase audit assessing the impact of a technological intervention on the quality of radiology requests with the results showing marked improvement in key parameters. A ...

Phase 1

Introduction:

In esophageal carcinoma, lymph node involvement is a crucial aspect of nodal staging and determining treatment strategies. Although grayscale endoscopic ultrasound (EUS) is the standard of care for staging, it is unable to identify lymph node drainage from primary tumors or sentinel lymph nodes (SLN). The goal of this study was to determine if Contrast Enhanced Endoscopic Ultrasound (CE- EUS) is superior to EUS in the identification of SLNs and nodal staging in esophageal carcinoma.

Methods:

In the unblinded pilot study, patients with newly diagnosed esophageal carcinoma were recruited to undergo CE-EUS and standard EUS. EUS was performed and ...

Radiation Medicine Faculty Publications

Translational animal models for oral mucositis (OM) are necessary to simulate and assess the bioclinical effects and response in humans. These models should simulate high levels of radiation exposure that leads to oxidative stress and inflammatory‐initiated tissue changes. Hamster models have been extensively studied to observe pathological effects of radiation exposure and help in the development of effective treatments. To successfully evaluate the potential for treatment regimens with consistency and relevance, a radiation‐induced OM hamster model was developed using a clinical linear accelerator utilized by cancer patients daily. The dose exposure to the isolated, everted cheek pouch of ...
