Virtual Colonoscopy in Colorectal Cancer Prevention and Screening

...rectal cancer can be done// by a three-dimensional computed tomography (CT) colonography or virtual colonoscopy. More people would want to be screened by this method when it is covered by third-party payers. "Our positive experience with virtual colonoscopy screening covered by health insurance demonstrates...

Researchers Study Effects Of Fat Around The Heart

...unty. The study uses the latest tests, including computed tomography, ultrasound, and magnetic resonance imaging, to screen healthy men and women between the ages of 45 and 84 for early heart disease. After the initial screenings for heart disease, the study will measure the occurrence of heart attacks, str...

The Pain from Fibromyalgia Is Real, Researchers Say

...esonance imaging (fMRI) and single photon emission computed tomography (SPECT) – indicate there is a difference between patients with and without fibromyalgia. “In people without pain, these structures encode pain sensations normally. In people with fibromyalgia, the neural activity increased,” says Daniel ...

Inhaled Particles Increases the Risk of Lung Cancer

... by Dr. McCunney on recent studies suggesting that computed tomography scans might be an effective way to screen for early-stage lung cancers in workers with certain occupational exposures, as well as in smokers. The studies in the special issue help to advance scientific understanding of the relationships ...

Surfing Safer Than Soccer: Study

Researchers, in the first study of its kind, have computed the rate of injury among competitive surfers and found they are less prone to harm than collegiate soccer or basketball// players. Led by researchers at Rhode Island Hospital and Brown Medical School, the findings of the study are published in the Ja...

Relationship Between Delirium and Dementia

...mission tomography (PET) and single photo emission computed tomography (SPECT) -- which offer the possibility of using highly sensitive imaging techniques to detect changes in the brain following episodes of delirium and thereby investigate the mechanisms and networks involved in its onset and consequences. ...

New Computed Imaging Technique Uses Hazy Images to Improve View

New Guidelines For Assessing Lymphoma Treatment

...an by normal tissue. In contrast to conventional computed tomography (CT) or magnetic resonance imaging (MRI), PET is able to distinguish between viable tumor and non-cancerous scar tissue that is often left behind after successful treatment of lymphoma. Incorporation of PET imaging into response assessment...

Cataplexy During Status Cataplecticus Resembles REM Sleep

... the use of brain perfusion single photon emission computed tomography (SPECT), have led to the discovery that cataplexy during status cataplecticus, a case of prolonged cataplexy, partially resembles normal rapid eye movement (REM) sleep but without the other imaging characteristics of this state, according ...

Lung Cancer Risk High Among Women

...t recent studies suggest that a test called spiral computed tomography can detect lung cancer when it is still curable. If you’re considering having a screening test, the March 2007 issue of Harvard Women’s Health Watch suggests you weigh the following factors. The benefit. Women have more to gain from scre...

No Survival Benefit for CT Screening for Lung Cancer

... first report of an international study looking at computed tomography (CT) to screen current or former smokers for lung cancer found that screening did not reduce deaths from lung cancer.// Although CT screening found nearly three times as many lung cancers as predicted, the researchers found that early det...

Calcium in Arterial Plaque is a Good Indicator for Risk of Stroke

RF Ablation a Safe Alternative Option for Treating Lung Cancer

...aluated the outcomes of 153 patients who underwent computed tomography (CT)-guided RF ablation for 189 inoperable lung cancers, including 116 primary lung cancers and 73 metastases to the lung from other cancers. The majority of the patients, who ranged in age from 17 to 94, also suffered from severe cardiopu...

Follow Screening Regimen for Early Cancer Detection

Researchers find that annual computed tomography (CT) screening plays a vital role in identifying early-stage lung cancer//. “The regimen of screening determines how early the cancer is diagnosed. This is critical, as it provides the opportunity for earlier treatment which can be curat...

Cryoablation: A New Treatment Option for Some Kidney Tumor Patients

...being treated cannot be effectively monitored with computed tomography (CT) or ultrasound. The Mayo study findings show that cryoablation can be used for some larger tumors with simultaneous operation of multiple cryoprobes guided by ultrasound. The ablation margin (the edge of the frozen tissue) can be accur...

CT Imaging With Novel Contrast Agent May Predict Heart Attack in Waiting

... Mount Sinai School of Medicine have shown the use computed tomography (CT) imaging along with a novel contrast agent know as N1177 can detect dangerous, high-risk plaque which cause heart attack and stroke. The findings may help physicians diagnosis a heart attack before the attack occurs. High-risk plaque...

Study Finds the Effect of Alcohol and Aspirin in TBI Patients

...admission to the hospital, and degree of injury on computed tomography (CT) scanning. It is known that up to 50 percent all cases of ICH can increase with time, resulting in worsening neurological status and appearance on CT scan. More than half of the patients brought to the hospital with TBI are intoxicat...
