NCT02163005
Patients with an allergy to iodine based intravenous contrast cannot undergo a CT scan with contrast, unless they are premedicated. Premedication can result in a delay in diagnosis, that can be significant with acute conditions such as Pulmonary embolism. The investigators are evaluating the use of Gadolinium as an alternative contrast agent in CT. Gadolinium has been used extensively in MRI exams but the dose that is used is not sufficient to provide good enhancement on CT. Dual Energy CT is a new technology that has better sensitivity to lower doses of intravenous contrast and the investigators aim to study its effectiveness in improving the enhancement with Gadolinium. The investigators will compare enhancement of Iodine with enhancement of Gadolinium during Dual Energy CT, to assess the possibility that Gadolinium could be used as an alternative for patients who are suspected of having Pulmonary embolism. They will recruit up to 50 patients who are having a routine Chest CT during treatment for a malignancy and administer Gadolinium contrast and Iodine contrast during a chest CT exam. The enhancement with the two agents can be compared.
NCT00951496
This randomized phase III trial studies bevacizumab and intravenous (given into a vein) chemotherapy to see how well they work compared with bevacizumab and intraperitoneal (given into the abdominal cavity) chemotherapy in treating patients with stage II-III ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer. Monoclonal antibodies, such as bevacizumab, can block the ability of tumor cells to grow and spread by blocking the growth of new blood vessels necessary for tumor growth. Drugs used in chemotherapy, such as paclitaxel, carboplatin, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving bevacizumab together with intravenous chemotherapy is more effective than giving bevacizumab together with intraperitoneal chemotherapy in treating patients with ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer.
