Indigenously Developed Close Delivery System For Oral Iodine-131 Therapy: Nominal Cost But Phenomenal Protection., Imran A Shah

Department of Radiology

Abstract

BACKGROUND:

Administration of radiopharmaceuticals through intravenous and oral routes is the major source of radiation exposure to nuclear medicine (NM) technologists. Adopting new strategies to minimize radiation exposure is an important step toward safe practice in nuclear pharmacy.

MATERIALS AND METHODS:

We have indigenously developed a relatively close delivery system for oral administration of radioiodine-131 ((131)I) to minimize radiation exposure to the technologists.

RESULTS:

The efficacy of this indigenously developed close system was assessed upon 23 patients who were given (131)I therapies for benign (13 patients) and malignant thyroid disorders (10 patients). There was 64 ± 6% (P < 0.05) reduction in exposure rate using indigenously developed delivery system.

CONCLUSION: …

An Unsuspected Bleeding Meckel's Diverticulum In An Adult Detected On Mesenteric Angiography, Muhammad Ali, Raza Sayani, Muhammad Azeemuddin, Tanveer-Ul-Haq, Rizwan Khan

Department of Radiology

Meckel's diverticulum is usually asymptomatic and found in almost 2% of the population. Haemorrhage from a Meckel's diverticulum is common in children but rare in adults. Here we report a case of 20 years old male with recurrent gastrointestinal bleeding. Meckel's diverticulum was diagnosed due to abnormal vascularity on mesenteric angiography and embolization was performed. Diagnosis was correlated with other radiological imaging and later elective resection was performed. This case is reported to emphasize the potential role of mesenteric angiography in the detection and management of bleeding Meckel's diverticulum and correlation with other radiological imaging.

Consistent Surgeon Evaluations Of Three-Dimensional Rendering Of Pet/Ct Scans Of The Abdomen Of A Patient With A Ductal Pancreatic Mass., Matthew E Wampole, John C Kairys, Edith P Mitchell, Martha L Ankeny, Mathew L Thakur, Eric Wickstrom

Department of Biochemistry and Molecular Biology Faculty Papers

Two-dimensional (2D) positron emission tomography (PET) and computed tomography (CT) are used for diagnosis and evaluation of cancer patients, requiring surgeons to look through multiple planar images to comprehend the tumor and surrounding tissues. We hypothesized that experienced surgeons would consistently evaluate three-dimensional (3D) presentation of CT images overlaid with PET images when preparing for a procedure. We recruited six Jefferson surgeons to evaluate the accuracy, usefulness, and applicability of 3D renderings of the organs surrounding a malignant pancreas prior to surgery. PET/CT and contrast-enhanced CT abdominal scans of a patient with a ductal pancreatic mass were segmented into 3D …

The Impact Of Lateral Electron Disequilibrium On Stereotactic Body Radiation Therapy Of Lung Cancer, Brandon Disher

Electronic Thesis and Dissertation Repository

Stereotactic Body Radiation Therapy (SBRT) is an effective treatment option for patients with inoperable early-stage lung cancer. SBRT uses online image-guidance technology [e.g. cone-beam CT (CBCT)] to focus small-fields of high energy x-rays onto a tumour to deliver ablative levels of radiation dose (e.g. 54 Gy) in a few treatment fractions (e.g. 3). For the combination of these treatment parameters and a low density lung, lateral electron disequilibrium (LED) can potentially occur, reducing lung and tumour doses. The goal of this thesis was to determine the impact of LED on stereotactic body radiation therapy for lung cancer.

Optimization Of A Boundary Element Approach To Electromagnet Design With Application To A Host Of Current Problems In Magnetic Resonance Imaging, Chad T. Harris

Electronic Thesis and Dissertation Repository

Magnetic resonance imaging (MRI) has proven to be a valuable methodological approach in both basic research and clinical practice. However, significant hardware advances are still needed in order to further improve and extend the applications of the technique. The present dissertation predominantly addresses gradient and shim coil design (sub-systems of the MR system).

A design study to investigate gradient performance over a set of surface geometries ranging in curvature from planar to a full cylinder using the boundary element (BE) method is presented. The results of this study serve as a guide for future planar and pseudo-planar gradient systems for …

Body Mri Artifacts In Clinical Practice: A Physicist's And Radiologist's Perspective., Martin J Graves, Donald Mitchell

Department of Radiology Faculty Papers

The high information content of MRI exams brings with it unintended effects, which we call artifacts. The purpose of this review is to promote understanding of these artifacts, so they can be prevented or properly interpreted to optimize diagnostic effectiveness. We begin by addressing static magnetic field uniformity, which is essential for many techniques, such as fat saturation. Eddy currents, resulting from imperfect gradient pulses, are especially problematic for new techniques that depend on high performance gradient switching. Nonuniformity of the transmit radiofrequency system constitutes another source of artifacts, which are increasingly important as magnetic field strength increases. Defects in …

Marine-Lenhart Harboring Papillary Thyroid Cancer, Brian Y. Chou, Md, Sharon Segal, Do, Edmund A. Pribitkin, Md, Jeffery L. Miller, Md

Department of Otolaryngology - Head and Neck Surgery Presentations and Grand Rounds

Introduction

Graves' disease with functioning nodules is referred to as Marine-Lenhart Syndrome. Only 2.7% of the patients with Graves’disease have concomitant functioning nodules.¹ Thyroid scintigraphy often definitively confirms the diagnosis. However, in addition to a hyperfunctioning (i.e. "hot") nodule, the thyroid scan may reveal isofunctioning (i.e. "warm"), and or a nonfuntioning (i.e. "cold") nodule as compared to the normal surrounding thyroid. Since hyperfuntioning nodules rarely harbor malignancy, if one is found that corresponds to the nodule in question, no cytologic evaluation is usually necessary.² Conversely, the majority of all nonfunctioning nodules may be benign or less frequently malignant, …

Hepatic Artery Pseudoaneurysm Mimicking Mirizzi Syndrome, Zahid Anwar, Raza Sayani, Darakshan Kanwal, Mohammed Ali, Mohammed Anwar Saeed

Department of Radiology

Acute cholecystitis leading to development of a pseudoaneurysm of the hepatic artery is a very rare complication; however, a pseudoaneurysm resulting in gallbladder neck compression with dilatation of intrahepatic duct giving a Mirizzi syndrome like presentation is virtually unreported to the best of our knowledge. We report a case of a 60 years male patient who presented in emergency department with right hypochondrial pain and mild jaundice. Initial diagnosis of hepatic artery pseudoaneurysm causing compression of neck of gallbladder and common bile duct was made on ultrasound examination. This was resulting in gross distention of gallbladder and mild dilatation of …
