Changes in brain density can help predict schizophrenia
Changes in brain density could be used to predict whether an individual who is at risk for schizophrenia is likely to develop the condition or not. view more (2006-12-07)
CT scans better than X-rays when detecting abnormalities in patients with H1N1 virus
Computed tomography (CT) scans are better than standard radiography (X-rays) in showing the extent of disease in patients with the H1N1 virus. view more (2009-10-21)
Compiling Multiple CT Scans Simplifies Probe Repositioning During Radiofrequency Ablation
Merging multiple CT images (summation of CT scans) increases the accuracy of probe repositioning during radiofrequency ablation treatments of various lesions, according to a recent study performed at Dartmouth-Hitchcock Medical Center in Lebanon, NH. view more (2008-09-04)
Hazards of CT scans overstated
Concerns over possible radiation effects of CT scans detailed in a report yesterday in the New England Journal of Medicine should not scare people away from getting medically needed CT scans, as the scans play a critical role in saving the lives of thousands of people every day. view more (2007-12-03)
Columbia researchers: Growth of CT scan use may lead to significant public health problem
Computed Tomography (CT) scans are an increasingly used X-ray-based tool for providing a three-dimensional view of a particular organ or tissue. view more (2007-11-29)
CT scans show patients with severe cases of H1N1 are at risk for developing acute pulmonary emboli
Researchers utilizing computed tomography (CT) scans have found that patients with severe cases of the H1N1 virus are at risk for developing severe complications, including pulmonary emboli (PE). view more (2009-10-14)
Type of lung cancer screening used to detect disease may impact 5-year survival rates
Dr. Hisao Asamura and his team of researchers at The National Cancer Center Hospital in Tokyo, Japan examined the records of 2,281 patients who underwent lung cancer resection surgery between 2000 and 2006. view more (2009-05-05)
Patients may want to skip that cup of coffee before undergoing PET/CT scans
Patients who need a positron emission tomography (PET)/computed tomography (CT) procedure to evaluate known or suspected malignancies should lay off the java, according to research by Medhat M. Osman, M.D., Ph.D., assistant professor in the department of internal medicine's division of nuclear medicine and director of PET at Saint Louis University... view more... (2005-06-21)
Scan visualises poor memory in the elderly
Dutch psychologists have found that elderly persons with a poor memory demonstrate less activity in the mediotemporal lobe when storing new information than elderly persons with a normally functioning memory. Sander Daselaar from the Free University of Amsterdam made scans of the activity in various brain areas. These showed differences between... view more... (2003-03-21)
Concern over safety of commercial ultrasound scans
Expectant parent' desire to see images of their unborn children has given rise to commercial companies offering keepsake ultrasound scans without medical supervision, often referred to as "boutique ultrasonography." view more (2007-02-06)
New imaging compound might 'see' Alzheimer's earlier
A new imaging molecule that can detect and map plaques and tangles in the brains of people with Alzheimer's disease could eventually lead to earlier diagnosis of the devastating disease, researchers at the University of California, Los Angeles report in the Dec. 21, 2006, issue of the New England Journal of Medicine. view more (2006-12-21)
Imaging technique helps predict breast cancer spread before surgery
Whole-body positron emission tomography (PET) scans could help physicians determine whether breast cancer has spread to the lymph nodes in the armpit prior to surgery. view more (2006-08-22)
Low dose radiation in infancy may affect intellect
Exposure to low doses of ionising radiation in infancy affects intellectual capacity in later life, conclude researchers from Sweden in this week's BMJ. CT scanning, which delivers high doses of ionising radiation, is increasingly being used in young children after minor head trauma. The study involved 3,094 men who had received radiation therapy... view more... (2004-01-03)
New technology developed at Barrow Neurological Institute enhances MRI capabilities
Researchers at Barrow Neurological Institute in Phoenix have developed a new method that allows technicians to obtain clearer Magnetic Resonance Imaging (MRI) scans with less sensitivity to patient motion. view more (2006-01-05)
Skin Condition Linked to Genetics in Caucasian and Chinese Populations
A study at the University of Sheffield in the UK was conducted on the skin condition called psoriasis, revealing a link between susceptibility to psoriasis and regions on chromosomes 6p21 and 4q28-q31. According to the study, psoriasis, a chronic inflammatory dermatosis, is believed to be inherited and triggered by environmental, as well as... view more... (2004-07-15)
MRI/PET Scanner Combo
Two kinds of body imaging -- positron emission tomography (PET) and magnetic resonance imaging (MRI) -- have been combined for the first time in a single scanner. view more (2008-03-10)
Experts warn over health check brain scans
A new study has voiced concern about the growing market for brain screening tests, which people can buy as part of a general health MOT. view more (2009-09-04)
PET Scans May Improve Accuracy of Dementia Diagnosis
A new study shows that the use of positron emission tomography (PET) scans may improve the accuracy of dementia diagnoses early in disease onset for more than one out of four patients. view more (2009-06-16)
Iterative reconstruction technique significantly reduces patient radiation dose during CT scans
Computed tomography (CT) scans are responsible for more than two thirds of the total radiation dose associated with medical imaging exams. view more (2009-08-19)
Mathematicians find way to improve medical scans
Mathematicians at the University of Liverpool have found that it is possible to gain full control of sound waves which could lead to improved medical scans, for technology such as ultra sound machines. view more (2008-01-08)
