Utility And Accuracy Of Primary And Secondary Ultrasonographic Signs For Diagnosing Acute Appendicitis In Pediatric Patients, W. Akhtar, Mujtaba Z. Naveed, Kumail Khandwala

Department of Radiology

Introduction Making an accurate diagnosis of acute appendicitis (AA) is vital to prevent the morbid complications associated with untreated AA. This is challenging in up to 30% of pediatric patients which is a significantly high number. Ultrasound (US) has been generally used as the initial mode of imaging in pediatric patients due to the lack of ionizing radiation. Given its variable accuracy, adjuvants such as secondary signs can be used to aid the radiologist in making an accurate diagnosis. Materials and methods Patients between the ages of two and sixteen years with acute abdominal pain suspicious for AA, who underwent …

Focal electrical stimulation of the brain incites a cascade of neural activity that propagates from the stimulated region to both nearby and remote areas, offering the potential to control the activity of brain networks. Understanding how exogenous electrical signals perturb such networks in humans is key to its clinical translation. To investigate this, we applied electrical stimulation to subregions of the medial temporal lobe in 26 neurosurgical patients fitted with indwelling electrodes. Networks of low-frequency (5-13 Hz) spectral coherence predicted stimulation-evoked increases in theta (5-8 Hz) power, particularly when stimulation was applied in or adjacent to white matter. Stimulation tended …

Lonidamine (LND), a metabolic modulator, sensitizes DB-1 human melanoma to doxorubicin (DOX) chemotherapy by acidifying and de-energizing the tumor. This report compares the effects of LND on two human melanoma lines, DB-1 and WM983B, which exhibit different metabolic properties. Using liquid chromatography mass spectrometry and Seahorse analysis, we show that DB-1 was more glycolytic than WM983B in vitro. ³¹P magnetic resonance spectroscopy (MRS) indicates that LND (100 mg/kg, i.p.) induces similar selective acidification and de-energization of WM983B xenografts in immunosuppressed mice. Over three hours, intracellular pH (pHi) of WM983B decreased from 6.91 ± 0.03 to 6.59 ± 0.10 (p …

Radiation In Its Origin: Health Risks Resulting From Prolonged Exposure To Radon, Tetiana Soloviova, Evans Lespinasse

Publications and Research

Among non-smokers, radon is the number one cause of lung cancer, and the second cause of lung cancer overall, according to the Environmental Protection Agency. Radon cannot be detected through one's sense of sight, smell, hearing, taste or touch. The only way to detect it is by testing certain spaces or environments with specialized instruments. This radioactive gas is present in trace quantities in the earth and produced by decaying uranium. It enters buildings through cracks in walls, floors, construction joints or gaps around service pipes, electrical wires and sump pits. It emits heavy nuclear fragments of alpha particles (two …

Upper Gastrointestinal Bleed Embolization With Onyx®: The "Tattoo Effect", Driss Raissi, Qian Yu, S. Houssam Mardini

Radiology Faculty Publications

Endoscopic intervention is well validated for the control of upper gastrointestinal bleeding (UGIB). In cases of refractory bleeding, transarterial embolization is a safe and effective alternative. Ethylene vinyl alcohol (EVOH) commonly known as Onyx^® is an inherently black liquid embolic approved for use in cerebrovascular arteriovenous malformations and is increasingly used as an embolic agent in multiple peripheral and visceral territories. Onyx^® has a uniquely undesirable property of causing black color discoloration when used in peripheral applications adjacent to the skin akin to a "tattoo effect." Knowledge of the agents used by the interventional radiologist, clinical correlation, and …

Functional Brain Activation Changes Associated With Practice In Delaying Smoking Among Moderate To Heavy Smokers: Study Protocol And Rationale Of A Randomized Trial (Cope)., Andrew T. Fox, Delwyn Catley, Kimber P. Richter, Edward F. Ellerbeck, Morgan G. Brucks, Vlad B. Papa, Laura E. Martin

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Most smokers struggle to overcome tobacco addiction. Neuroscientific models of addiction emphasize the importance of brain regions associated with cognitive control and reward to understand the cycle of addiction and relapse. During an attempt at abstinence, the cognitive control system appears to be underpowered to override the heightened reward system of the addicted brain. Thus, one neural target for treatment is to strengthen the cognitive control system. It may be possible to improve the functioning of the cognitive control system via deliberate practice.

METHODS/DESIGN: This study will determine the effects of practicing delaying smoking on brain and behavioral measures …

While there are several techniques proven to acquire DTI data, there are no standardized accepted methods for acquisition and processing. As more medical systems are utilizing this technology to evaluate the spinal cord, it is important to study the reproducibility of the DTI metrics among various scanner platforms, coil configurations and software implementations to determine the variance in obtaining normative spinal cord DTI data. This preliminary data for a multi-site DTI study examines the effects of these different MR …

Prevalence Of Subarachnoid Haemorrhage Among Patients With Cranial Venous Sinus Thrombosis In The Presence And Absence Of Venous Infarcts, Muhammad Azeemuddin, Muhammad Awais, Fatima Mubarak, Noor Ul-Ain Baloch

Department of Radiology

Introduction: In patients with cranial venous sinus thrombosis, the occurrence of subarachnoid haemorrhage in association with haemorrhagic venous infarcts is a well described phenomenon. However, the presence of subarachnoid haemorrhage in patients with cranial venous sinus thrombosis in the absence of a haemorrhagic venous infarct is exceedingly rare.
Methods: We retrospectively reviewed charts and scans of all patients who had cranial venous sinus thrombosis confirmed by magnetic resonance venography at our hospital between September 2004 and May 2015. The presence of subarachnoid haemorrhage was ascertained on fluid-attenuated inversion recovery, susceptibility-weighted imaging and/or unenhanced computed tomography scans by a single experienced …

Nanoparticles As Multimodal Photon Transducers Of Ionizing Radiation, Edwin C. Pratt, Travis M. Shaffer, Qize Zhang, Charles Michael Drain, Jan Grimm

Publications and Research

In biomedical imaging, nanoparticles combined with radionuclides that generate Cerenkov luminescence are used in diagnostic imaging, photon-induced therapies, and as activatable probes. In these applications, the nanoparticle is often viewed as a carrier inert to ionizing radiation from the radionuclide. However, certain phenomena such as enhanced nanoparticle luminescence and generation of reactive oxygen species cannot be explained by only Cerenkov luminescence interactions with nanoparticles. Herein, we report methods to examine the mechanisms of nanoparticle excitation by radionuclides, including interactions with Cerenkov luminescence, β particles, and γ radiation. We demonstrate that β scintillation contributes appreciably to excitation and reactivity in certain …

A Narrative Review On Contrast-Enhanced Ultrasound In Aortic Endograft Endoleak Surveillance., Sriharsha Gummadi, John R. Eisenbrey, Andrej Lyshchik

Department of Radiology Faculty Papers

Endovascular repair of abdominal aortic aneurysms have been performed successfully since 1991. However, 20% to 50% of these patients may develop an endoleak or continued aneurysmal sac expansion or perfusion despite stent graft coverage. Current recommendations suggest lifelong surveillance with computed tomographic angiography (CTA) at least 1 month after intervention and yearly after that. In select patients with a stable aneurysm sac on computed tomography performed 1 year after treatment, future screening could be performed with ultrasonography. However, color Doppler ultrasound can fail to detect as many as 31% of endoleaks. Contrast-enhanced ultrasound (CEUS) provides an alternative approach to excluded …

Use Of Ultrasound For Diagnosis Of Pneumonia In Adults, A Review, Dafang Chen, Rodrigo Cavallazzi

The University of Louisville Journal of Respiratory Infections

Pneumonia is a common lung infection with significant morbidity and mortality. Currently, the diagnosis of pneumonia is made by patient history confirmed with chest radiograph or computed tomography. These modalities, however, have limitations including low accuracy, radiation exposure, and high cost. Lung ultrasound has become more prevalent in evaluating pulmonary conditions and has shown to be highly accurate in the diagnosis of pneumonia. The purpose of this review is to discuss sonographic findings associated with pneumonia, techniques used to obtain quality images, and the evidence in literature supporting the use of lung ultrasound in the diagnosis of pneumonia. Numerous studies …

Role Of Multi-Parametric (Mp) Mri In Prostate Cancer, Syed Muhammad Nazim, Ather Enam, Basit Salam

Section of Urology

Multi-parametric magnetic resonance imaging is increasingly being recommended as standard imaging modality for prostate cancer diagnosis and staging. It comprises structural T2 and T1 sequences supplemented by functional imaging techniques, i.e. diffusion-weighted, dynamic contrast enhanced and spectroscopic imaging. Pre-biopsy multi-parametric magnetic resonance imaging is recommended for both detection and staging as it avoids biopsy artefact, and when normal, has a negative predictive value of 95% for significant cancer. Magnetic resonance imaging-guided prostate biopsy targets only area(s) considered to be suspicious for prostate cancer, hence resulting in improved accuracy. Dynamic contrast enhancing helps in the detection of cancer and for the …
