Inflammatory bowel diseases (IBD), such as Crohn's disease and ulcerative colitis, may be detected and monitored more effectively in the future with positron emission tomography/computed tomography (PET/CT), according to research published in the May issue of The Journal of Nuclear Medicine. Typically assessed by endoscopic and histologic evaluations, investigators demonstrated the ability of PET/CT to identify lesions along the complete intestinal wall that could be missed with traditional imaging techniques. http://medicalxpress.com/news/2013-05-inflammatory-bowel-disease-petct.html Diseases, Conditions, Syndromes Wed, 01 May 2013 15:52:19 EST news286642326 (HealthDay)—Abdominal computed tomography (CT) imaging, conducted for other indications, can be used to identify patients with osteoporosis, according to a study published in the April 16 issue of the Annals of Internal Medicine. http://medicalxpress.com/news/2013-04-routine-ct-imaging-osteoporosis.html Cancer Wed, 17 Apr 2013 05:08:21 EST news285394089 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 A multi-center analysis, led by Weill Cornell Medical College and published in the Journal of Clinical Gastroenterology, shows the use of temporary "fully covered self-expanding metal stents" (FCSEMS) can effectively fix a painful and potentially life-threatening benign biliary stricture—a severely blocked or narrowed bile duct. http://medicalxpress.com/news/2013-03-metal-stents-effective-treatment-blocked.html Cardiology Wed, 20 Mar 2013 13:34:21 EST news283005254 The underlying medical conditions facing young adults who undergo computed tomography (CT) exams represent a significantly greater health risk than that of radiation-induced cancer from CT, according to a new study published online in the journal Radiology. http://medicalxpress.com/news/2013-02-benefits-ct-outweigh-cancer-young.html Cancer Tue, 05 Feb 2013 00:00:01 EST news279222680 (Medical Xpress)—With demand for unresolved back pain relief growing as the U.S. population ages, Rush University Medical Center is doing more minimally invasive spine surgery procedures that allow patients to return to normal, day-to-day activities faster than if they undergo conventional surgery. http://medicalxpress.com/news/2013-01-minimally-invasive-spine-surgery-real-time.html Surgery Tue, 15 Jan 2013 08:30:01 EST news277460037 According to an article in the November issue of the Journal of the American College of Radiology, a medical imaging facility in San Diego, Imaging Healthcare Specialists, has implemented a successful radiation dose reduction program, reducing radiation exposure by up to 90 percent in some patients. http://medicalxpress.com/news/2012-11-imaging-facility-successful-dose-reduction.html Cancer Mon, 05 Nov 2012 16:33:49 EST news271355623 Giving some bowel cancer patients six weeks of chemotherapy before surgery can significantly shrink their tumour, making it easier to remove and potentially reducing the chances of the cancer coming back, according to results from a major Cancer Research UK-funded pilot study published this month in Lancet Oncology. http://medicalxpress.com/news/2012-11-bowel-cancer-chemo-swap-tumours.html Cancer Thu, 01 Nov 2012 10:06:05 EST news270983151 Early signs of lung cancer could be diagnosed using a simple blood test following a new discovery by scientists at the University of York. http://medicalxpress.com/news/2012-10-closer-lung-cancer-blood.html Cancer Mon, 15 Oct 2012 15:00:17 EST news269518514 Video gamers are generally the biggest consumers of computer graphics cards, using the devices to boost the speed and resolution of their digital quests to fend off invading extraterrestrials or outwit hostile dragons.

While this addition increases the amount of radiation dose a patient receives, research presented at the Society of Nuclear Medicine's2012 Annual Meeting finds that multiple molecular imaging studies need only one structural scan, which would slice off a significant amount of patient radiation exposure. http://medicalxpress.com/news/2012-06-reconfigured-hybrid-imaging-lowers-exposure.html Cancer Mon, 11 Jun 2012 14:30:03 EST news258639918 (HealthDay) -- There is a strong association between degenerative spondylolisthesis and spinous process fracture in patients undergoing interspinous process spacer (IPS) surgery, according to a study published online May 24 in The Spine Journal. http://medicalxpress.com/news/2012-06-spondylolisthesis-linked-spinous-fractures.html Diseases, Conditions, Syndromes Sat, 02 Jun 2012 04:50:01 EST news257829849 Radiologists and nuclear medicine physicians recommended additional imaging about 30% of the time in oncologic PET/CT reports, with about half of those recommendations being unnecessary, a new study shows. http://medicalxpress.com/news/2012-05-necessity-additional-imaging-petct-oncologic.html Cancer Fri, 04 May 2012 01:30:01 EST news255312493 National Jewish Health is seeking to refine and improve lung-cancer screening by combining a blood test with CT imaging to detect disease earlier and more effectively.

As a result of imaging with the radiopharmaceutical 3,4-dihydroxy-6-F-18-fluoro-L-phenylalanine (F-18-DOPA), physicians changed the intended management plan for 41 percent of patients with brain tumors. http://medicalxpress.com/news/2012-03-pet-tracer-brain-tumor-patients.html Cancer Thu, 01 Mar 2012 11:00:02 EST news249821026 A study presented at SNM's 58th Annual Meeting may provide a new tool for detection of malignant-stage ovarian cancer. Researchers found that positron emission tomography and computed tomography (PET/CT), which images both functional and anatomical changes in the body, was useful for preoperative cancer imaging of ovarian masses when used with a radiotracer that is actively metabolized by cells as fuel. Physicians imaging patients suspected of having malignant tumors can see where cancerous cells are hyper-metabolizing the tracer and accurately predict whether a mass is malignant, cancerous but stable, or benign. http://medicalxpress.com/news/2011-06-pet-imaging-malignancy-potential-ovarian.html Cancer Mon, 06 Jun 2011 21:10:01 EST news226584500 The coronary arteries of Princess Ahmose-Meryet-Amon - as visualised by whole body computerised tomography (CT) scanning - will feature in two presentations at the International Conference of Non-Invasive Cardiovascular Imaging (ICNC) this week in Amsterdam (15-18 May).
