Inferior vena cava filter placement is done to prevent or treat pulmonary emboli or deep venous thrombosis. http://medicalxpress.com/news/2013-04-venous-intravascular-ultrasound-guided.html Diseases, Conditions, Syndromes Fri, 19 Apr 2013 00:00:03 EST news285522614 One view 3D breast screening (tomosynthesis) means less radiation dose and about five seconds less compression, but a study from Yale University, New Haven, CT, found that obtaining both views is necessary to help ensure that a cancer won't be missed. http://medicalxpress.com/news/2013-04-views-d-breast-screening.html Cancer Fri, 19 Apr 2013 00:00:02 EST news285522593 Adding "chemical shift" techniques to MRI can help differentiate clear cell renal cell carcinoma from other types of renal cell cancer, a new study shows. That differentiation can help physicians better determine treatment for these patients. http://medicalxpress.com/news/2013-04-chemical-shift-mri-differentiate-renal.html Cancer Fri, 19 Apr 2013 00:00:01 EST news285522547 A new minimally invasive tumor ablation technique is providing hope for liver cancer patients who can't undergo surgery or thermal ablation, a study shows. http://medicalxpress.com/news/2013-04-ablation-technique-liver-cancer-patients.html Cancer Thu, 18 Apr 2013 00:00:04 EST news285436299 Screening breast ultrasound performed after mammography on women with greater than 50% breast density detects an additional 3.4 cancers or high risk lesions per one thousand woman screened, a detection rate just under that of screening mammography alone for women with less dense breasts, a new study shows. Screening mammography detects 4-5 cancers per thousand women screened. http://medicalxpress.com/news/2013-04-screening-breast-ultrasound-cancers-mammography.html Cancer Thu, 18 Apr 2013 00:00:02 EST news285436385 Multispectral photoacoustic imaging, which combines laser optics and ultrasound imaging technologies, can reliably distinguish between benign and malignant prostate tissue, a new study indicates. http://medicalxpress.com/news/2013-04-laser-optics-ultrasound-imaging-noninvasive.html Cancer Thu, 18 Apr 2013 00:00:01 EST news285436272 Combining CT imaging findings with baseline serum lactate dehydrogenase levels is showing promise as a way to predict survival in patients with metastatic melanoma being treated with anti-angiogenic therapy. http://medicalxpress.com/news/2013-04-ct-serum-ldh-survival-predictor.html Cancer Wed, 17 Apr 2013 00:00:03 EST news285354211 The estimated size of chest lymph nodes and lung nodules seen on CT images varies significantly when the same nodes or nodules are examined using lower versus higher doses of radiation, a new study shows. The size of lymph nodes and lung nodules is an important determinant of treatment and treatment success. http://medicalxpress.com/news/2013-04-dose-affects-size-lesions-chest.html Cancer Wed, 17 Apr 2013 00:00:02 EST news285354233 Radiation dose reduction has moved to the forefront of importance in medical imaging with new techniques being developed in an effort to bring doses down as low as possible. What difference can these techniques make? Researchers at Indiana University School of Medicine aimed to find out. http://medicalxpress.com/news/2013-04-iterative-reconstruction-longitudinal-dose-modulation.html Cancer Wed, 17 Apr 2013 00:00:01 EST news285354249 Adding a photo of a face to x-ray images can reduce "wrong-patient" errors five-fold, a new study finds. http://medicalxpress.com/news/2013-04-picture-wrong-patient-errors.html Cancer Mon, 15 Apr 2013 00:00:02 EST news285143610 It is unnecessary to scan trauma patients based on a non-focused standard trauma CT protocol, if the patient is transferred for care after already undergoing a focused CT examination based on the patient's history and physical examination, a new study shows. http://medicalxpress.com/news/2013-04-standard-ct-protocol-trauma-patients.html Cancer Mon, 15 Apr 2013 00:00:01 EST news285143636 Tomosynthesis (3D mammography) is better able to show infiltrating ductal carcinoma than 2D mammography in women at increased risk of breast cancer, a new study shows. http://medicalxpress.com/news/2013-04-tomosynthesis-infiltrating-ductal-carcinoma-patients.html Cancer Sat, 13 Apr 2013 04:32:13 EST news285046324 Dual energy CT is an effective way to evaluate emergency department patients with possible anterior cruciate ligament (ACL) tears, a new study shows. ACL tears are one of the most frequent ligamentous injuries of the knee; they are not commonly diagnosed in the emergency department because they are not seen on plain x-rays. http://medicalxpress.com/news/2013-04-dual-energy-ct-accurately-acl.html Other Sat, 13 Apr 2013 04:31:52 EST news285046305 MDCT is a better way to measure annular size in patients with aortic stenosis who are candidates for transcatheter aortic valve implantation (TAVI) than two dimensional echocardiography, a new study indicates. http://medicalxpress.com/news/2013-04-mdct-valve-implant-size-transcatheter.html Cardiology Sat, 13 Apr 2013 04:31:31 EST news285046279
