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 ... Read More

The purpose of this study is to determine if the measurement (with a standard nuclear camera) of radioactivity normally present in the nervous system of your heart at four hours after the injection of radioactive drug for your diagnostic I-123 MIBG scan is any different than radioactivity measured in your heart at one and/or two hours after your diagnostic scan injection. If equivalent information to the conventional 4 hr H/M ratio could be collected by ... Read More

This study will compare the safety and effectiveness of PF-05280586 versus rituximab-EU in patients with CD20-positive, low tumor burden follicular lymphoma. The primary hypothesis to be tested in this study is that the effectiveness of PF-05280586, as measured by the Overall Response Rate, is similar to that of rituximab-EU. Read More

This is an interdisciplinary study that falls into the Humanitarian Use Device category. There are no hypotheses to be tested in this treatment protocol. The study has the following objectives: 1. Provide supervised access to treatment with TheraSphere® to eligible patients with primary cancer to the liver who are not surgical resection candidates. 2. Evaluate patient experience and toxicities associated with TheraSphere® treatment. 3. ... Read More

Percutaneous, image-guided tumor ablation has evolved as a genuine alternative for the treatment of unresectable hepatocellular carcinoma. Published data exploring stereotactic or proton beam percutaneous irradiation have revealed,that hepatocellular carcinoma (HCC) is radiosensitive to certain protocols. In Phase I and II studies, the investigators investigated the potential role of local irradiation in primary and secondary liver tumors employing a ... Read More

Distal embolization can occur during coronary angioplasty performed in the acute phase of myocardial infarction and is associated with poor long-term outcome. We hypothesize that the use of a system allowing thrombus aspiration before angioplasty and stent implantation will limit infarct size and its severity. Read More

Background: - Noninvasive cardiac stress testing is imperfect. Inconclusive test results generate further expensive testing. - In patients with known or suspected coronary artery disease, both computed tomography (CT) and magnetic resonance imaging (MRI) have been shown to provide suitable results for detecting the disease. However, both types of scans have limitations in their usefulness, and it is not known whether one is ... Read More

The purpose of this study is to determine the use of 177Lu-PP-F11N for imaging and therapy of patients with advanced medullary thyroid carcinoma (MTC). 177Lu-PP-F11N is a gastrin analogon, binding to cholecystokinin-2 receptors. This receptors show an overexpression on more than 90 % of medullary thyroid carcinomas. In the pilot (phase 0) study we will correlate the tumour detection rate with the surgery and histology (proof of concept study). Furthermore, ... Read More

Background: The field of nuclear medicine has changed a lot in the past decades. Technology has gotten better, so patients are exposed to less radiation. But now workers are doing procedures more often and using lead aprons less. So they may be exposed to more radiation. This may put them at higher risk for cancers and other health problems that are related to radiation. Researchers want to collect data from technologists to learn more about the risks and ...

The synergistic value of the fusion of physiologic and anatomical data has been described using several co-registration techniques for various nuclear medicine procedures and morphologic imaging modalities (single photon emission computed tomography-computed tomography [SPECT-CT], SPECT-magnetic resonance imaging [MRI], camera-based positron emission tomography [PET]-CT and PET-CT). The researchers hypothesize that fusion of nuclear medicine (NM) and CT data ... Read More

This study will develop and evaluate new techniques for computer-aided detection and diagnosis (CAD) of medical problems using images from diagnostic tests such as computed tomography (CT), ultrasound, nuclear medicine and x-ray images. The Food and Drug Administration has approved CAD techniques for detecting masses and calcifications on mammography and lung nodules using chest x-rays. Many other applications of CAD would potentially benefit patients. This ... Read More

Pain during nuclear medicine breast lymphnode detection procedures has been reported as high as 8.8/10. Using Sodium Bicarbonate to alkalinize the radio-pharmaceutical injection, pain can safely be reduced from 6.6/10 to 4.7/10, during breast lymph node detection procedures. In sites other then the breast, using Bicarbonate to make the injection's pH closer to natural, attempts to lower the pain levels will be performed. Hypothesis: The perceived pain ... Read More

The incidence of hemodynamically relevant dialysis fistula stenoses/obstructions after 1 year is between 60-90% (from 62.5 to 91% radiocephalic, brachiocephalic 70-84%, PTFE shunts 62-87%), necessitating a therapeutic measure to preserve dialysis access during this period in 1/3 of the patients. This therapeutic measure is a dilatation of the stenosis using a standard PTA balloon (POBA, plain old balloon angioplasty with a primary technical success rate of ... Read More

Ionizing radiation has a number of harmful effects in humans. The most important among these is the induction of cancer. It is assumed that damage to DNA in the nucleus of a single cell can induce cancer. Among the different types of lesions inducted, DNA double-strand breaks (DSBs) are considered to be the most relevant effects that can initiate carcinogenesis. The investigators are already conducting several other studies to prospectively compare the ... Read More
