(HealthDay)—For young adults needing either a chest or abdominopelvic computed tomography (CT), the short-term risk of death from underlying morbidity is greater than the long-term risk of radiation-induced cancer, according to a study published in the May issue of Radiology. http://medicalxpress.com/news/2013-05-ct-indicator.html Cancer Mon, 20 May 2013 14:20:01 EST news288273516 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 Severity of emphysema, as measured by computed tomography (CT), is a strong independent predictor of all-cause, cardiovascular, and respiratory mortality in ever-smokers with or without chronic obstructive pulmonary disease (COPD), according to a study from researchers in Norway. In patients with severe emphysema, airway wall thickness is also associated with mortality from respiratory causes. http://medicalxpress.com/news/2013-01-severity-emphysema-mortality.html Diseases, Conditions, Syndromes Fri, 18 Jan 2013 00:00:02 EST news277661731 (HealthDay)—The impact of different screening modalities on cancer risk has been quantified in two studies presented at the annual meeting of the Radiological Society of North America, held from Nov. 25 to 30 in Chicago. http://medicalxpress.com/news/2012-11-rsna-breast-ca-prior-ct.html Cancer Tue, 27 Nov 2012 20:10:03 EST news273262209 Young patients who undergo chest or abdominopelvic CT are more than 35 times more likely to die of their disease than develop a radiation induced cancer, according to an analysis of 23,359 patients, some of whom were scanned more than 15 times. http://medicalxpress.com/news/2012-05-ct-induced-cancer-minimal-dying-disease.html Cancer Tue, 01 May 2012 03:05:07 EST news255060289 An article in the September issue of the Journal of the American College of Radiology summarizes methods for radiation dose optimization in chest computed tomography (CT) scans. Chest CT is the third most commonly performed CT examination, frequently used to diagnose the cause of clinical signs or symptoms of the chest, such as cough, shortness of breath, chest pain or fever. http://medicalxpress.com/news/2011-09-experts-pointers-optimizing-dose-chest.html Cancer Thu, 01 Sep 2011 04:45:23 EST news234071115 Researchers from Boston University School of Medicine (BUSM) have found that computed tomography pulmonary angiography (CTPA), meant to improve detection of life-threatening pulmonary embolisms (PE), has led to over-diagnosis and over treatment of this condition. These findings, which appear in May 9 issue of the Archives of Internal Medicine. may continue to grow worse as the as the use of CT scans continue to rise. http://medicalxpress.com/news/2011-05-evidence-over-diagnosis-pulmonary-embolisms-result.html Cancer Mon, 09 May 2011 16:40:04 EST news224177189 The use of breast shields is the technique of choice to protect the breasts of women from radiation exposure while undergoing chest CT examinations, according to a new study. http://medicalxpress.com/news/2011-05-breast-shields-dose-posteriorly-centered.html Cancer Wed, 04 May 2011 04:58:54 EST news223703922 Recent studies have shown that a 64-detector CT angiography utilizing prospective electrocardiographic (ECG) gating produces a quality image but considerably reduced patient radiation dose when compared to retrospective ECG gating, according to research being presented at the 2011 American Roentgen Ray Society's annual meeting. http://medicalxpress.com/news/2011-05-low-dose-chest-ct-effective-cardiothoracic.html Cancer Wed, 04 May 2011 04:57:36 EST news223703835
