CT Scans Said to Accurately Detect Small Cancers

...diological Society of North America shows computed tomography scans may accurately detect small cancers and stones in the kidneys, bladders and urinary tracts of high-risk patients.// Multi Detector CT Urography ( MDCTU ) scans can be performed using helical CT scanners, which pass X-rays through the body fro...

Sympathy and brain function

...very early age. Researchers used positron emission tomography (PET) to explore the neural mechanisms of imitation by measuring increases in blood flow in the brain. In the study where researchers looked at imitation, they discovered a consistent pattern of increased brain activity involving the superior tempora...

OCT - Optical Coherence Tomography - the buzzword in cardiology

...vard Medical School who has used optical coherence tomography to gauge stent status.// This is a new imaging technique similar to ultrasound and will allow cardiologists to view the status of coronary stents used to open clogged arteries during angioplasty. A more glamorous way of putting it would be to ...

Overactive brain regions can lead to anorexia nervosa

...e disorder. Researchers had used positron emission tomography (PET) imaging to find out about the function and the level of activities of brain dopamine receptors. Researchers could only include women who had recovered from the disorder versus normal women for their study, as women who are still suffering from ...

PET scans can detect the results of cognitive behavior therapy

Positron emission tomography (PET) scan images can successfully detect the changes in the brain // that occur following the cognitive behavior therapy in patients. Researchers behind the study feel that this may prove that cognitive behavior therapy can bring about changes in th...

Caffeine can interfere with PET scan results

MRI for distinguishing between dementia and Alzheimer’s diseas

...low is usually measured by using positron emission tomography or single proton emission computerized Tomography that involves injecting the patients with radioactive tracers. These expensive procedures are time consuming as well. The advent of the new technique will not only be non-invasive, but quick and easy ...

Predicting Severity Of Appendicitis With Computed Tomography

...on the findings of a clinical tool called computed tomography can be used to predict the severity of acute appendicitis, // according to a new study. Researchers examined 105 patients, between ages 15 and 89 who underwent an appendectomy within three days of an abdominal CT. Results of the CT were compared w...

Understanding The Harmful Effects Of Radiation Exposure

Being Obese Increases Ones Risk Of A wrong Diagnosis During Medical Imaging

...uracy of imaging equipment scans, such as computed tomography (CT) and magnetic resonance imaging (MRI). The number of problems with imaging overweight people nearly doubled from 0.10 percent to 0.19 percent in the past decade, which correlates with the increase in obesity statistics which have nearly doubled ...

Loss Of Brain Tissue Linked To Obesity

...dy and were followed from 1968 to 1992. A computed tomography (CT) scan conducted at the final exam found nearly 50 percent of the women had lost brain tissue, mainly in the temporal lobe. Women with this loss of brain tissue had an average BMI of 27, about one- to 1.5-points higher than women without the brain...

Effective Diagnosis Of Spinal Cord Injuries

...y and who were assessed with both MRI and computed tomography at admission and at a follow-up examination about 10 months later. They examined whether there is an association between the degree of spinal cord injury compression in the period just after traumatic injury and clinical neurological outcome. They fo...

Urine Test for Kidney Cancer

...y to detect kidney cancer is with a computed axial tomography scan or magnetic resonance imaging, but Frozzitta's tests showed uncertain results. "Seventy percent to 90 percent of kidney masses that appear to be malignant on CAT scans or MRI are, which means that 10 percent to 30 percent are not. Unfortunately...

A Combination Of Drugs Effective In The Treatment Of Hormone-Refractory Prostate Cancer

...cific antigen (PSA) of more than 50%, the computed tomography findings did not show an equivalent response. The patients' median time to progression was 10 months, with a range of 6 months to over 20 months. Two patients are living; 8 died due to disease progression; and 2 died of other causes. The toxicity ...

PET Scans Found To Reveal Hidden Cancers

New research shows positron emission tomography scans not only detect known abnormalities in cancer patients but // may also identify new, unrelated cancers. Researchers evaluated 1,750 PET scans of patients with known or suspected cancers to determine if the scans also identify unexpected abnorm...

Radiation Exposure Found To Affect Intellect Later In Life

Since diagnosis is difficult, about 25 percent to 40 percent of people who are diagnosed with the disease are already in an advanced stage. However, the cancer is often curable if caught early. Finding a s...

Treating Stroke Patients in Rural Areas
