Smokers who receive abnormal results using computed tomography to screen for lung cancer are more likely to quit

According to a new study, smokers who receive multiple abnormal results using computed tomography (CT) to screen for lung cancer are more likely to quit, suggesting an opportunity for doctors to motivate smokers to quit smoking.

Movie techniques, MRI/CT data combine with computer modeling of knee/patella to aid surgery

Take the kinds of movie techniques that allow animation with true-life action, throw in an anatomically-based muscle, ligament, tendon, bone and soft-tissue geometries dataset, and add individual patient MRI or CT scan data.

Benefits of lung cancer screening with CT questioned

Annual screening with helical computed tomography (CT) can help radiologists detect lung cancers at their earliest, most curable stage, but has not been shown to reduce mortality from the disease, according to a study published in the April issue of the journal Radiology.

Combining PET and CT scans leads to more accurate radiation therapy for lung cancer patients

Using Positron Emission Tomography in addition to Computed Tomography can reduce the amount of radiation exposure to normal tissue in some lung cancer patients

PET and CT scans provides accurate detection and localization of foot infection in diabetic patients

Pioneering research with combined positron emission tomography (PET) and computed tomography (CT) scans provides accurate detection and localization of foot infection in diabetic patients, according to an article in the March issue of the Journal of Nuclear Medicine.

Whole-body computed tomography (CT) is not a cost-effective screening method

The use of whole-body CT as a screening tool for cancer and other diseases is the focus of an ongoing debate. Proponents of whole-body CT emphasize the potential benefit of early detection of disease, but others caution that the costs, false-positive findings and unnecessary radiation might render the procedure more harmful than beneficial.

Blood clots in the lungs could be prevented with computed tomography (CT) scans of the legs

Researchers found that indirect CT venography (CTV) could identify blood clots in the legs that have the potential to break free, travel to the lung and block an artery--a life-threatening condition known as pulmonary embolism.

Researchers can now predict the likelihood of developing lung cancer

For the first time, researchers can predict the lung cancer risk for social smokers as well as habitual smokers.

Virtual colonoscopy raises issues for further study

The American Society for Gastrointestinal Endoscopy (ASGE) has reacted with caution to claims of the benefits of computed tomography (CT) colonography, also referred to as virtual colonoscopy, compared to standard colonoscopy.

Early results shed light on lung cancer screening advance

One in three smokers or former smokers screened for lung cancer at a baseline and one year follow-up visit using a recent advance in computed tomography tested positive according to a new study. Of those, 12 percent had lung biopsies, and 7 percent were diagnosed with lung cancer.

New data supporting the use of Renagel in patients who are new to hemodialysis

Genzyme Corporation announced that investigators tomorrow will unveil new preliminary data supporting the use of Renagel (sevelamer hydrochloride) in patients who are new to hemodialysis.

New computational techniques that can allow medical doctors to visualise and assess micro-vessel blood flow in tumours

Researchers at the Nanyang Technological University (NTU) Singapore, have developed new computational techniques and algorithms that can allow medical doctors to visualise and assess micro-vessel blood flow in tumours.

Dolphins brain size helps to provide some answers to how the species evolved in relation to humans

The intelligence and cognitive capabilities of dolphins and their aquatic cousins have long fascinated the public and the scientific community, but the question of how and why they have such large brains has mostly gone unanswered.

New statement published on nonmalignant diseases related to asbestos exposure

In its first official statement since 1986 on the topic, the American Thoracic Society (ATS) has published a document entitled “Diagnosis and Initial Management of Nonmalignant Diseases Related to Asbestos.”

Enhanced technology with improved features drives the mobile medical imaging equipment market

The increasing demand for digitisation among hospitals and high price of static modalities are driving demand for mobile medical imaging equipment.

CT scans may be delivering as much radiation as a low-dose atomic bomb

Those full-body CT scans advertised at some health care centers may be delivering as much radiation as a low-dose atomic bomb, according to a new study. And that means people who get them could be raising their cancer risk, researchers from Columbia University report in the journal Radiology (Vol. 232, No. 3:735-738).

Blacks and whites have similar amounts of coronary calcium deposits, which are a sign of atherosclerotic plaques

In contrast to earlier studies that indicated African-Americans tend to have lower amounts of atherosclerosis than whites, despite having higher cardiovascular death rates, heart scans in a large, representative population indicate that blacks and whites have similar amounts of coronary calcium deposits

Research provides definitive evidence that radiation risk is associated with full-body CT scans

The risk of cancer mortality from a single full-body computed tomography (CT) scan is modest, but not negligible, and the risks resulting from elective annual scans are much higher, according to a study published in the September issue of the journal Radiology.

Surgeons remodel and replace man's jaw bone allowing him to eat first dinner in 9 years

“By the 4th week post-transplantation the patient enjoyed his first dinner in 9 years (bread and sausages); before reconstruction he had only been able to eat soft food and soup”.
