Health: Improving the recognition of brain tumours
Researchers at the Institute of Nuclear Chemistry in Jülich have developed a short-lived, radioactive amino acid that delivers much more precise information on brain tumours and their structure than was possible in the past. By combining positron emission tomography (PET), a process that visualises the spread of radioactive substances in the... view more... (2005-05-04)
Combination of PET/CT tests can expedite diagnosis of lung cancer in a fast-track setting
Research published in the October 2009 issue of the Journal of Thoracic Oncology has found an effective combination of positron emission tomography (PET)/computed tomography (CT) (PET/CT) tests to diagnose lung cancer in a "fast-tracked" outpatient setting. view more (2009-10-01)
Hybrid Scanner Brings Molecular Functioning to the Forefront
A major barrier to developing a hybrid positron emission tomography (PET)/magnetic resonance (MR) imaging system could be removed by using a novel approach for reconstructing data. view more (2009-06-16)
EU joint effort leads to better cancer diagnosis in northern Italy
Since March 16, one of the most important drugs used primarily to diagnose cancer was made available for commercial production and distribution in some hospitals and treatment centres in northern Italy. The availability of the drug, 18F-Fludeoxyglucose (18F-FDG), is the result of a joint agreement between the Institute for Health and Consumer... view more... (2004-04-27)
Early detection of lung cancer: New data presented at multidisciplinary meeting
New data from several studies evaluating new techniques for early diagnosis and treatment of lung cancer are being presented at the first European Multidisciplinary Conference on Thoracic Oncology (EMCTO) in Lugano, Switzerland (1-3 May 2009). view more (2009-05-04)
Patients may want to skip that cup of coffee before undergoing PET/CT scans
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... view more... (2005-06-21)
Warp speed brings Dirac into the 21st century
You`d be forgiven for thinking that an American predicted anti-matter. Or that it only existed in Star Trek. In fact, it was Paul Dirac, a Bristol born physicist, who predicted the stuff that propels starships in science fiction movies and who has also influenced much of our modern day technology, for example, computers. Today, 8 August is the... view more... (2002-08-06)
Combining PET and CT scans makes cancer treatment more accurate
Doctors have discovered that combining images derived from positron emission tomography and computed tomography in the planning and delivery of radiation treatment for patients with head and neck cancer leads to more accurate delivery of the radiation dose and an increased chance for survival. view more (2006-05-02)
18F-DG PET/CT can highly increase the detection of colorectal cancer
Combined positron emission tomography and computed tomography (PET/CT) is currently widely used in the clinical diagnosis of cancer to provide functional and morphological imaging. view more (2007-10-11)
Rochester researchers delve into concussions
Concussion patients with a normal head CT scan may believe they are free of brain injury, but CT scans often miss damage at the molecular level, warns a University of Rochester Medical Center study. view more (2006-03-01)
Fusing physics with medicine to fight cancer
Everyone's lives are touched by cancer - it is a disease that affects 1 in 3 of us throughout our lifetime. Future developments that lead to earlier diagnosis and more effective therapy lie in further successful collaboration between high energy physicists and the healthcare industry. view more (2005-04-28)
A potential new imaging agent for early diagnosis of most serious skin cancer
Scientists in Australia are reporting development and testing in laboratory animals of a potential new material for diagnosing malignant melanoma, the most serious form of skin cancer. view more (2009-10-01)
FLT PET Assesses Treatment Response on Tumor Growth—Not Size—With Non-Hodgkin's Lymphoma
Positron emission tomography (PET)—with the radiolabeled thymidine analog [18F]Fluorothymidine (FLT)—is "a promising, sensitive tool" for assessing drug effects on tumor growth in patients with diffuse large B-cell lymphoma. view more (2006-06-07)
Johns Hopkins Researchers Study Nearly 2,000 Cancer Patients and Detect Unexpected, Additional Malignancies
A team of researchers at Johns Hopkins Medical Institutions in Baltimore, Md., reports that whole-body positron emission tomography/computed tomography (PET/CT) scans may help physicians identify new, unexpected malignant cancerous tumors in patients, according to an article in the May issue of the Society of Nuclear Medicine's Journal of Nuclear... view more...

New image analysis techniques to monitor how breast tumours respond to drugs
New techniques that might allow magnetic resonance imaging (MRI), to be used to give doctors subtle information about a tumour’s physiology and how it reacts to drug therapy are being developed. view more (2001-12-18)
Ultrasound more cost efficient than other medical imaging choices
In comparing ultrasound with other medical imaging methods such as MRI and CT scans, a literature review of published studies in the May/June issue of Journal of Diagnostic Medical Sonography (JDMS) describes the use of ultrasound to provide an accurate diagnosis more cost effectively than the alternatives. view more (2009-05-21)
EARLY DETECTION OF LUNG CANCER POSSIBLE WITH CAT AND PET SCANS (pp 588, 593)
Issue 23 August 2003 Embargoed 0001 h (London time) 22 August 2003. Preliminary results from a European study in this week's issue of THE LANCET show that combined use of spiral computed tomography (CT) and positron emission tamography (PET) scanning can reliably detect early lung cancer. Authors of the study suggest that use of these imaging... view more... (2003-08-20)
Molecules of positronium observed in the laboratory for the first time
Physicists at UC Riverside have created molecular positronium, an entirely new object in the laboratory. Briefly stable, each molecule is made up of a pair of electrons and a pair of their antiparticles, called positrons. view more (2007-09-13)
From diagnostic tool to cancer therapy
Cancer patients could be benefiting more than they realise from diagnostic scans. Research published today in Breast Cancer Research suggests that a radioactive molecule widely used to evaluate advanced tumours can kill cancer cells. Dr Ekaterina Dadachova and her team from the Albert Einstein College of Medicine of Yeshiva University, USA,... view more... (2003-08-20)
New mammography technology effective in detecting breast cancer
A study has found that positron emission mammography (PEM), a new technique for imaging the breast, is not affected by either breast density or a woman's hormonal status, two factors that limit the effectiveness of standard mammography and MRI at detecting cancer. view more (2008-12-02)
