58 Clinical Trials for Various Conditions
This study explores the use of virtual reality (VR) to reduce pain and anxiety during thyroid biopsies and PICC line insertions under local anesthesia. One group experienced the procedure with VR, while the other group did not. Participants completed questionnaires before and after the surgery to measure pain and anxiety levels. The main goal is to observe if VR can significantly decrease pain and anxiety during these procedures.
This clinical trial is a prospective study of radiosurgery treatment for progressive GBM to test 1)the efficacy of radiosurgery for recurrent/progressive GBM compared to chemotherapy , and 2) the role of diffusion-weighted image (DWI) to predict the early tumor progression and treatment response.
Patients are being asked to participate in a study to better determine blood flow going to tumors in the liver. They will undergo an embolization procedure in interventional radiology where the goal is to provide treatment directly into the liver tumor. These treatments are delivered into the blood vessels feeding the tumors. Improving these treatments relies on better understanding the blood flow into the tumor. By understanding how much blood flows into the tumors, the goal is to make sure there is the best chance of killing the tumor. The investigators are attempting to use a special type of CT scan during the procedure to determine the blood flow to the tumors.
This is a research study to evaluate change in Quality of Life, as defined by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC C-30), from baseline to 1 month post treatment in two patient cohorts receiving Interventional Radiology Liver Directed Therapies or Hypofractionated Image-Guided Radiation Therapy.
The study will prospectively analyze the analgesic and anxiolytic effects of thermomechanical stimulation (cold and vibration effects) with or without patient selected music preference during non-sedating interventional radiology procedures.
This trial studies how well Optiflow THRIVE works in delivering oxygen to patients during total intravenous anesthesia while undergoing radiology procedures. The Optiflow THRIVE is an oxygen administration device that delivers high-flow and humidified oxygen through the nose. The Optiflow THRIVE device may improve oxygen delivery and reduce breathing complications.
The objective of this research is to use the Clear Guide SCENERGY technology, an FDA approved Ultrasound-CT fusion imaging system, that allows the user to fuse CT images onto a real-time ultrasound that is being performed on the patient. This fusion system will be used to perform ultrasound guided needle placements for patients undergoing percutaneous CT guided needle-based intervention. This study will consist of 20 patients, 10 patients using the CGM SCENERGY US-CT system and 10 patients using guidance only. The primary goal of the study is to prove that the new imaging fusion system is comparable to using either CT or US guidance alone to guide needle placement.
The goal of the study is to determine whether clinical decision support (CDS) for radiology affects the number, type, or appropriateness of targeted high-cost radiology imaging orders (i.e. magnetic resonance (MR), computed tomography (CT), nuclear medicine (NM) and Positron Emission Tomography (PET) scans). The CDS will be delivered to physicians in the Aurora Health Care system. It will be delivered in Epic, an industry-standard electronic medical record software, through ACR Select, which is a leading decision support tool based on the American College of Radiology (ACR) Appropriateness Criteria (see http://www.acr.org/Quality-Safety/Appropriateness-Criteria). The ACR Select tool rates imaging orders on a scale of 1-9 with 1-3 labelled as 'usually not appropriate', 4-6 'May be appropriate', and 7-9 'usually appropriate'.
The purpose of this study is to assess the accuracy and utility of point-of-care ultrasound (POCUS) of the bladder compared to patient's sensation of bladder fullness in predicting the ability to successfully perform a comprehensive transabdominal pelvic ultrasound in the pediatric Emergency Department (ED). We hypothesize that POCUS can more accurately and more quickly determine adequate bladder fullness to successfully perform transabdominal pelvic ultrasound than patient's perception of bladder fullness.
The goal of the study is to determine whether clinical decision support (CDS) affects the number, type, or appropriateness of targeted high-cost radiology images (i.e. MR and CT) ordered. The CDS will be delivered in Epic through ACRSelect software, which is a leading decision support tool based on the American College of Radiology (ACR) Appropriateness Criteria (see http://www.acr.org/Quality-Safety/Appropriateness-Criteria), and presents the ACR appropriateness scores for each image on a scale of 1-9 with 1-3 labelled as 'usually not appropriate', 4-6 'May be appropriate', and 7-9 'usually appropriate'.
Malignant ascites leads to significant morbidity in patients with terminal cancer. Paracentesis can provide relief, but repeat hospital visits, pain, and short duration of relief after paracentesis are detrimental to quality of life(QOL). Two devices are available as alternatives to paracentesis. The impact of either device on QOL has not fully been explored. A pilot nonrandomized trial measuring palliative care QOL and ascites symptom relief using validated survey instruments is proposed.
The study will test a hypothesis that the AccuCath™ System will have a higher rate of successful first attempt peripheral IV placement and higher clinician and patient satisfaction compared to Conventional IV Catheters.
The PREFER II trial primary objective of the trial is to show how much radiation attenuation is provided by XPF thyroid collars in absolute and relative terms.
The purpose of this study is to analyze the findings of 30 surgeons and 30 nuclear radiologists of 61 individual thyroid scans. The goal is to determine if surgeons are more prone to making a definitive diagnosis based on a given scan than a nuclear radiologist. Accuracy of localization of the two groups will be analyzed. A secure website has been designed to which the physician will be able to login and view and rate the quality of each image and make a localizing diagnosis. Once they are finished, they will not be able to make any more changes, and their responses will be compared to the responses of their colleagues. The results will be analyzed to find if there is a significant variation in the ratings between the surgeons and the nuclear radiologists as to the quality, location, and number of parathyroid glands, if any, on the scans.
The PREFER Trial primary objective of the trial is to show how much radiation attenuation is provided by XPF in absolute and relative terms.
The purpose of this study is to collect data on the standard of care use of the St. Jude Medical (SJM) Angio Seal™ Evolution™ and V-Twist Integrated Platform (VIP) Devices in diagnostic and/or interventional radiology patient populations.
We propose an observational study to assess the ability of intensivists to evaluate for deep vein thrombosis using 2 point compression ultrasonography.
The purpose of this study is to quantify levels of resident anxiety under the current system (take call alone) and compare results to a modified system.
Primary Objectives: * To measure and record patients' pain levels before, during, and after standard procedures performed in IR. * To compare different procedures to respective pain levels and patient satisfaction (as determined by questionnaire).
This study aims to test the effectiveness of virtual reality (VR) as a non-pharmaceutical intervention to reduce pain and anxiety in children undergoing peripheral intravenous catheter (PIVC) access in the Department of Radiology and Imaging or the outpatient Infusion Center at CHLA, as measured by self- and proxy-report.
Background: Radiologic images are getting more complex. They are also being used more often. Medical personnel are overwhelmed with data. Computer Aided Detection (CAD) and diagnosis may be able to improve medical care. Researchers want to create and test ways to use CAD. To do this, they want to use data from the Clinical Center s Department of Diagnostic Radiology. Objective: To create algorithms and software that accurately detect and characterize lesions, model anatomy, and monitor diseases on radiologic studies. Eligibility: People of all ages who have radiologic exams stored in the clinical PACS (picture archiving system) of the Clinical Center since July 6, 1953 with no end date. People with target lesions of any kind will be included. Design: This study will use existing data. Participants will include males and females of all ages. They will be chosen by keyword search on NIH databases. The data that is used may include CT, MRI, ultrasound, and other images. It may include a participant s name, date of birth, and date of exam. It may include the name of the doctor, radiologist, and hospital. Data such as age, gender, race, disease, and treatment may be used. Other data from charts or studies may be used. Imaging data of all organs of the body will be studied. Data will be kept in computers and servers. The equipment will be password protected. Printouts will be stored in locked rooms. This study will last 10 years.
Brief Summary A task like breast cancer screening (mammography) can be described as a "hybrid search" task. In basic visual search tasks, observers search for a target among distractors that are not the target. In hybrid search, observers search for two or more target types. In mammography, observers are searching for masses, calcifications ("calcs"), and some other signs of cancer like architectural distortion. In this experiment, the investigators have created a simulated version of mammography where non-expert (non-radiologist) observers can look for simulated masses and calcs. There are two types of stimuli, a 2D version (like an x-ray) and a 3D version (like the output of Digital Breast Tomosynthesis - DBT). The question that is being asked is whether it is better to ask about masses and calcs separately (first one, then the other) or to just let observers look for both at the same time.
This study aims to test the effectiveness of virtual reality (VR) as a non-pharmaceutical intervention to reduce pain and anxiety in children undergoing painful procedures in Phlebotomy, Radiology, Infusion, Orthopedics, Gastroenterology, and Immunology, amongst others, at CHLA, as measured by self- and proxy-report. Examples of the painful procedures include IV sticks, cast removals, allergy testing, and anorectal manometries.
This is a prospective, observational study designed to evaluate the role of dynamic computed tomographic perfusion (CTP) and Computed Tomography-Derived Fractional Flow Reserve (CT-FFR) in patients presenting with chest discomfort.Patients with lesions greater than 50% and who meet all other inclusion/exclusion criteria will qualify to be a subject in the CTP study /CT-FFR 49. Those who agree to participate will be scheduled to have the CT-FFR and CTP performed within sixty days of the initial Coronary CTA procedure. A CTA will be performed at rest for FFR. The patient will then take approximately a 30 min break. Regadenoson will then be administered and the dynamic CT procedure will be done for perfusion. If patients are deemed to be appropriate for invasive angiography by the referring physician, coronary lesions between 40% and 80% will get a fractional flow measurement performed if indicated on a clinical basis. Stenosis in vessels less than 1.5 mm will be excluded from the study. The CT-FFR and CTP will be performed in these patients within 60 days of index coronary angiography.
Does a radiology clinical dashboard increase radiologist use of specific reporting language for chest X-rays (CXRs) and thereby decrease rates of unnecessary Emergency Department (ED) prescriptions and follow-up imaging?
One method of breast cancer screening involves radiologists reading digital tomosynthesis (DBT) images. DBT consists of a 3D stack of x-ray "slices" through the breast. The exam is accompanied by a 2D image like a standard mammogram, a single x-ray of the breast. In a screening setting, most cases are normal. Sometimes it is obvious that a case is normal from a quick look at the 2D image. It would speed up the process of screening if readers could dismiss a clearly normal case on the basis of the 2D image, alone, without looking at the DBT images. Obviously, the investigators would only want to "triage" cases in this way if the investigators were almost perfectly sure that no cancers would be missed. In this study, the investigators look at radiologist's willingness to triage cases and on the accuracy of their answers. In addition, the investigators ask about the impact of an Artificial Intelligence (AI) opinion. Would it be possible to triage an image on the basis of the AI opinion, alone? Radiologists will look at each case for up to five seconds and offer an opinion (on a 1-10 scale) about how sure they are that a case is normal. Next, they will see the opinion of the AI. Finally, they will say (using a 1-10) scale, how willing they would be for the AI to triage this case without human intervention. This study is the start of an effort to understand the conditions under which radiologists might be willing to declare a case "normal" with little or no human examination.
The objectives of this project are to (1) assemble a crowdsourced, de-identified radiographic repository; and (2) train and validate existing COVID-NET deep learning diagnostic models.
Magnetic resonance imaging is an important and increasingly prevalent imaging modality used in healthcare. Children often find the procedure anxiety provoking causing difficulty in staying still and providing quality images. The use of preparation techniques including play therapy and role play utilizing such tools as a fiberglass mock MRI have shown to reduce anxiety and facilitate better image quality. Modalities of preparation including Virtual Reality (VR) pose as an alternative to habituate children for a MRI procedure.
The purpose of this study is to assess the safety and performance of the HydroMARK Breast Biopsy Site Marker manufactured in the Devicor Medical Products, Inc. Tijuana facility.
The overall goal of this project is to compare the absolute quantification of myocardial perfusion done by using CT myocardial perfusion imaging (CT-MPI) and the coronary flow measured by using CT Fractional Flow Reserve analysis (CT-FFR) to the gold standard represented by PET myocardial perfusion imaging (PET-MPI).
