Contrast agents are useful in computed tomography due to their ability to opacify internal structures for easier viewing. This …

Low Dose Computed Tomography In Lung Cancer Diagnosis, Jocelyn M. King

Student Research Poster Presentations 2024

This project explains the role of low-dose computed tomography (LDCT) aiding in the diagnosis of lung cancer. General statistics, risks, signs, symptoms of lung cancer, as well as low dose scans are discussed. In addition, the doses of routine chest computed tomography scans (CT) and low-dose are compared. Lung cancer is the second most common form of cancer in the United States, however early detection with the use of LDCT reduces mortality rate. About 80% of lung cancer diagnosis is caused by smoking. The use of LDCT reduces mortality rate in addition to a lower dose to the patient. Risks …

Subdural Hematomas And The Help Of Computed Tomography, Kelsey Jackson

Medical Imaging Senior Posters

Subdural hematomas can occur at any age but are most commonly seen in the elderly population. Subdural hematomas affects 21 in every 100,000 individuals, and are becoming more common. They can occur for a variety of reasons such as trauma or underlying health conditions. Subdural hematomas occur due to a collection of blood in the subdural space between the dura and arachnoid mater. Computed tomography is the best imaging modality in the aiding of diagnosing subdural hematomas due to the easy accessibility, short scan times, and the ability to create cross sectional images. Subdural hematomas can be classified into categories …

Detecting A Pulmonary Embolism Using Computed Tomography, Marissa O'Brien

Medical Imaging Senior Posters

Abstract

A pulmonary embolism is a potentially fatal disease in which a blood clot obstructs the pulmonary artery. Pulmonary emboli affect thousands of people every year in the United States. A timely diagnosis is vital to ensure quick and proper treatment and resolution. Signs and symptoms can vary among different patients, but some include shortness of breath, chest pain, syncope, and leg pain. Computed tomography (CT) is the golden standard for diagnosis, specifically a CT pulmonary angiogram, which quickly and accurately visualizes clots in the pulmonary artery using iodinated contrast in the form of a bolus better than any other …

Computed Tomography Simulation In Radiation Therapy For Non-Small Cell Lung Cancer, Victoria Narbone

Student Research Poster Presentations 2023

The purpose of this research is to educate readers on the role of computed tomography (CT) simulation in the radiation therapy process, specifically for patients with lung cancer. The goal of radiation therapy treatment is to maximize the dose to a target, usually a tumor, while minimizing the dose to the normal surrounding tissue. CT imaging creates cross-sectional images of the patient’s anatomy which can be used to create a treatment plan. In non-small cell carcinoma (NSCLC) there are four critical structures of concern including the spinal cord, esophagus, heart, healthy lung. CT simulation uses images to localize the tumor …

Ct-Guided Bone Biopsy, Meredith Lambertino

Student Research Poster Presentations 2022

Abstract

Bone biopsies are used to diagnose cancer that may have spread to the bone or is already in the bone. For accurate cancer diagnoses, interventional radiology (IR) bone biopsies are best done under the guidance of computed tomography (CT) imaging. The equipment required for CT during this procedure includes a gantry, table, and operator console. IR supplies all the needles, sterile drapes, and CT Localization grid. Bone biopsies require the use of a variety of needles to plan the procedure and collect a cell sample for analysis. The benefits of this procedure include a brief recovery, a less invasive …

Imaging Aortic Pathologies In Computed Tomography (Ct), Hailey Clark

Medical Imaging Senior Posters

Computed tomography (CT) is an increasingly important imaging modality to visualization of aortic pathologies. The aorta is the largest vessel in the body and gives rise to several important arteries that supply surrounding organs, so pathologies of this vessel can prove dangerous. The two main pathologies that affect the aorta are aneurysms and dissections, each of which can rupture and quickly become fatal. Symptoms for these pathologies can vary widely but primarily include pain localized to the area of the aorta that is affected, with risk factors encompassing several heart conditions as well as genetic factors. The prognosis for aortic …

Computed Tomography Of Cardiac Malignancies, Nicholas Malloy

Student Research Poster Presentations 2021

Cardiac malignancies are tumors that develop in the heart; they are commonly asymptomatic, hard to locate and associated with a poor prognosis. The size and location of the tumor in the heart often play a role in the early or late discovery of the tumor. Cardiac malignancies can be either benign, such as cardiac myxoma or rhabdomyoma, or malignant, such as cardiac lymphoma or angiosarcoma. Fortunately, the advancement of imaging modalities—especially computed tomography—has improved early detection rates of cardiac tumors. Computed Tomography provides optimal spatial resolution for detection of malignancies and is typically more readily available than most modalities. Computed …

Low-Dose Lung Cancer Screening Computed Tomography, Makalie Blazick

Medical Imaging Senior Posters

Abstract

Low dose Computed Tomography (CT) screening is essential when finding and treating suspicious lung nodules. A CT machine uses a highly advanced detector assembly that measures the amount of radiation exiting the patient and records data. A CT machine also conducts three-dimensional reconstructions of images that is used for surgical planning, CT angiography (CTA), radiation therapy planning, and virtual reality imaging. The low dose lung cancer screening is usually reserved for older patients with the greatest risk of lung cancer, including former or current smokers. To determine if someone is eligible for low dose CT screening, the pack years …

New Dose Reduction Techniques In Computed Tomography, Andrew Taylor

Medical Imaging Senior Posters

The use of radiation reduction techniques in Computed Tomography (CT) is critical in reducing patient dose, and for establishing new standards in radiation monitoring and protection during imaging procedures. CT is used to obtain high quality image sets that contain more useful information than standard x-ray images for diagnostic purposes; however, it utilizes higher radiation dose. With the advancement of newer technologies and techniques, many CT procedures can be performed to achieve high-quality images while using less radiation, and in some cases, improve diagnostic quality as well. Assessing new dose reduction techniques for specific procedures in CT is useful for …

Single- And Dual-Energy Ct: A Comparison, Emilee Bixler

Student Research Poster Presentations 2020

This research offers a comparison of two types of computed tomography (CT) configurations by exploring each scanner type and the accompanying image specifications, protocols, radiation doses, geometric aspects, and photographic aspects of the resulting images. The comparison aimed to determine if single-energy CT (SECT) or dual-energy CT (DECT) had any clear advantages over the other scanner type. Several studies in the research resulted in DECT displaying a decrease in dose without compromising contrast-to-noise ratio (CNR). The studies in this research also showed DECT had a superior ability of decreasing iodine by 70% concentration dose while obtaining the same image quality …
