Ct Scan

An image produced by a CAT scanner. Also called CT scan. Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures of the body.

20% reduction in lung cancer mortality with low dose CT vs chest X ray
Scientists have found a 20 percent reduction in deaths from lung cancer among current or former heavy smokers who were screened with low-dose helical computed tomography (CT) versus those screened by chest X-ray. The primary research results from the National Lung Screening Trial (NLST) were published in the New England Journal of Medicine.

A better imaging agent for heart disease and breast cancer
Scientists are reporting development of a process for producing large quantities of a much-needed new imaging agent for computed tomography (CT) scans in heart disease, breast cancer and other diseases, and the first evidence that the material is safe for clinical use.

Airport full body scanners are safe, says ACR
Amid concerns regarding terrorists targeting airliners using weapons less detectable by traditional means, the Transportation Security Administration (TSA) is ramping up deployment of whole body scanners at security checkpoints in U.S. airports.

CT scans radiation raise cancer risk
Radiation doses from common CT procedures vary widely and are higher than generally thought, raising concerns about increased risk for cancer, according to a new study led by UCSF imaging specialists.

Gene variant linked to effectiveness of plavix
Patients with a certain genetic variation and who received the antiplatelet drug clopidogrel -- Plavix -- had a decreased platelet response to treatment, revealed by researchers.

Prostatectomy effective in men with aggressive prostate cancer
Prostate surgery prostatectomy is found very effective in preventing death in men with aggressive prostate cancers, revealed by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC), Cleveland Clinic and the University of Michigan.

CT colonography better for colorectal cancer screening
Computed tomographic (CT) colonography may offer patients at increased risk of colorectal cancer an alternative to colonoscopy that is less-invasive, is better-tolerated and has good diagnostic accuracy.

Men should get PSA testing at age 40
The American Urological Association (AUA) issued new clinical guidance – which directly contrasts recent recommendations issued by other major groups – about prostate cancer screening, asserting that the prostate-specific antigen (PSA) test should be offered to well-informed, men aged 40 years or older who have a life expectancy of at least 10 years.

X-rays help in early diagnosis of Parkinson's disease
It is estimated that 4 million people world-wide are suffering from Parkinson's disease, a complex disease that varies greatly among affected individuals.

Routine scans for low back pain do not improve outcomes
Physicians should not immediately order routine scans for low-back pain unless they observe features of a serious underlying condition, researchers in the Oregon Evidence-Based Practice Center at Oregon Health & Science University report.

Cardiac imaging exams have radiation risks
At the radiation dose levels used in cardiac imaging exams, such as cardiac CT or nuclear medicine scans, the risk of potentially harmful effects from ionizing radiation are low. However, since the exact level of risk is not known, people without symptoms of heart disease should think twice about seeking, or agreeing to, these types of cardiac studies.

MRI shows signs of multiple sclerosis before disease develops
With more and more people having brain MRIs for various reasons, doctors are finding people whose scans show signs of multiple sclerosis (MS) even though they have no symptoms of the disease.

Camera in a pill finds early signs of esophageal cancer
What if swallowing a pill with a camera could detect the earliest signs of cancer? The tiny camera is designed to take high-quality, color pictures in confined spaces. Such a device could find warning signs of esophageal cancer, the fastest growing cancer in the United States.

Australian Govt should allow GPs to order MRI scans for patients
The Australian Medical Association (AMA) has written to Health Minister, Nicola Roxon, urging her to implement the previous Government's policy to allow GPs to order Magnetic Resonance Imaging (MRI) scans for their patients. Prior to last year's election, it was announced that GPs would be able to directly refer patients for a Medicare-funded MRI scan of the knee or, where Multiple Sclerosis is suspected, of the brain.

Hazards of CT scans overstated in NEJM
A recent article by Drs. David Brenner and Eric Hall in the New England Journal of Medicine has suggested that the radiation dose from CT scans is a cause for concern, and may be responsible for a small percentage of cancer deaths in the United States. While the conclusions of the Brenner article have been portrayed by some as conclusive, in reality the scientific community remains divided in regards to the radiation dose effects of CT.
