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.

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.

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”.

Children who take steroid drugs for nephrotic syndrome do not suffer bone loss

Childhood nephrotic syndrome, which affects 3 out of 100,000 children, is the most common chronic kidney disease in children. Although it does not impair kidney function, it weakens the body's ability to remove water and salt from the blood, and causes swelling in the belly, legs, and around the eyes.

Researchers find way to detect dangerous brain swelling in diabetic children

A rare swelling of the brain that is nonetheless the most common diabetes-related cause of death for children with the disease could be caught earlier — potentially saving lives — if practitioners learn to recognize key signs, researchers at the University of Florida report.

Computed tomography may improve screening of latent atherosclerosis

Atherosclerosis is the progressive narrowing and hardening of the arteries over time, known to occur to some degree with aging; but other risk factors (such as high cholesterol, high blood pressure, smoking, diabetes and family history for atherosclerotic disease) that accelerate this process have been identified.

Ultra-fast computed tomography (CT) scanner to look inside the heart and its arteries for calcium build-up

Many times, people with heart disease have few visible symptoms. This is one of the reasons why heart disease is the number one killer for both men and women in America. Saint Louis University and SLUCare offer a non-invasive test that could save your life or the life of someone you love.
