Electron-beam computed tomography - a more accurate replacement for coronary catheterizations

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Still a long way to go in diagnostic evaluation of all patients who suffer ischemic strokes

Women who survive a stroke are less likely than men to get crucial tests of their heart and neck arteries that can help improve their treatment and reduce their risk of a second stroke, a new University of Michigan study finds.

Experimental radioactive compound can show images of heart damage up to 30 hours after a brief interruption of blood flow and oxygen

The discovery may help physicians in emergency rooms and in their offices determine whether a patient's chest pain, which may have subsided hours earlier, is related to heart disease or something else, such as indigestion.

SARS can infiltrate brain tissue

Severe acute respiratory syndrome (SARS), by its very name, indicates a disease of the respiratory tract. But SARS can also infiltrate brain tissue, causing significant central nervous system problems, according to an article in the Oct. 15 issue of Clinical Infectious Diseases, now available online.

Enhanced imaging techniques could improve medical diagnosis

Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either - lower medical costs, new treatments, and earlier disease detection.

Study indicates that patients with a cervical spinal injury may harbor additional spinal damage not visible on regular x-rays

In fact, more than a third of patients who were thought to have low-risk injuries actually have additional damage that may include significant fractures with the potential to produce serious spinal problems if not detected and treated properly.

Surgeons have, for the first time, successfully removed a tumour with the aid of new 3-D computer modelling software

German cancer surgeons have, for the first time, successfully removed a tumour with the aid of new 3-D computer modelling software which the designers say will make these operations safer and more accurate.

Electron-beam computed tomography best for evaluating adults with congenital defects in the heart arteries

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for identifying which adult patients face the greatest risk of sudden death from congenital abnormalities in the arteries supplying blood to the heart, according to a study in the September 2005 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Combined computed tomography (CT) and positron emission tomography (PET) - may detect the spread of head and neck cancer more accurately

"PET/CT is very helpful in determining where we should pinpoint our biopsies for recurrent disease," said Dr. Carol Shores, assistant professor of otolaryngology/head and neck surgery at UNC and the report's senior author. Shores is a member of the UNC Lineberger Comprehensive Cancer Center.

Positron emission tomography (PET) imaging can identify effectiveness of chemotherapy early in high-risk breast cancer patients

The effectiveness of chemotherapy in patients with advanced breast cancer can be evaluated earlier by using 18F-FDG positron emission tomography (PET) imaging over other conventional imaging procedures, according to an article in the July issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine.

Cancer vaccine combined with hormone-deprivation therapy can help patients with recurrence of prostate cancer

A new study finds that a cancer vaccine combined with hormone-deprivation therapy can help patients with recurrence of prostate cancer. The results of this clinical trial, led by scientists at the National Cancer Institute (NCI), part of the National Institutes of Health, appear in the August 2005 issue of the Journal of Urology.

Treatment options for skull base tumors

It is estimated that in 2000, more than 359,000 persons were living with a diagnosis of a primary brain tumor in the United States. In 2005, it is estimated that nearly 12,800 deaths will be associated with malignant tumors of the brain and other parts of the central nervous system. Brain tumors are the leading cause of cancer-related deaths in children age 19 and younger.

Researchers use PET/CT for molecular imaging of the heart

For the first time, researchers used positron emission tomography (PET)/computed tomography (CT) for imaging the subcellar function of the heart - from its subcellular function to its morphologic appearance. The results of the study were reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Obesity is associated with an impairment of coronary circulatory function

A team of University of California, Los Angeles researchers found that positron emission tomography (PET) can provide important information on the relationship between heart function and obesity. Their findings were reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

PET might be a promising tool for early prediction of response to chemotherapy for ovarian can

Noninvasive positron emission tomography (PET) imaging may allow earlier prediction of a patient's response to chemotherapy for ovarian cancer, according to research reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Patients who need PET/CT scans should avoid drinking coffee

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 Hospital.

High-tech imaging software locates more accurately the abnormal electrical impulses that produce heart arrhythmias

Loyola University Health System is one of the first hospitals in the United States to employ new high-tech imaging software - in conjunction with a three-dimensional cardiac mapping and navigation system - to locate more accurately the abnormal electrical impulses that produce heart rhythm disturbances (arrhythmias). This technology represents a major breakthrough in treating complex arrhythmias.
