Medical-imaging-achieved-without-tomography

2021 05 Nov

A research team, led by investigators at the University of California, Davis, and Hamamatsu Photonics, has demonstrated the first experimental cross-sectional medical image that doesn't require tomography. The work, published 14 October in Nature Photonics , could allow medical imaging with better sensitivity and time resolution.   Normally, X-ray...Read more

Nuclear-stress-test-identifies-heart-attack-risk-in-diabetics

2019 08 Jul

Nuclear stress tests reveal an increased risk of cardiac-related deaths in patients with diabetes, a new study in Radiology: Cardiothoracic Imaging confirms.     Positron Emission Tomography (PET) Myocardial Perfusion Imaging (MPI) uses radioisotopes and a special camera to capture how efficiently blood is flowing through the heart under stress....Read more

Imaging-modalities-in-pancreatic-cancer-diagnosis

2017 10 May

A systematic review concludes that different imaging modalities, except for positron emission tomography (PET), have comparable sensitivity, specificity and diagnostic accuracy for the diagnosis of pancreatic ductal adenocarcinoma. The findings are published in European Journal of Radiology. See Also : Benefit-Risk Assessment in Diagnostic Imaging...Read more

Antibody-gives-better-diagnosis-of-alzheimer-s-than-imaging-with-tracers

2016 22 Feb

Researchers in Sweden have found that an antibody gives more exact information than regular radioactive tracers used in PET brain scans, which could lead to more effective diagnosis of early onset Alzheimer’s disease and improvements in monitoring the effects of medication. Counting over 100,000 people, Alzheimer’s is the most common dementia...Read more

Oesophageal-cancer-pet-does-not-improve-treatment

2015 08 Sep

Positron emission tomography (PET) is increasingly being used to assess the effectiveness of chemo- or radiotherapy in patients with cancer of the oesophagus. Now researchers say that no robust evidence exists to show that PET improves the treatment for these patients. Their finding is reported in the journal Deutsches Ärzteblatt International . Cancer...Read more

Pet-imaging-detects-fast-growing-prostate-cancer

2015 25 Aug

A Johns Hopkins-led study shows that PET imaging with a specific biomarker could detect fast-growing primary prostate cancer and distinguish it from benign prostate lesions. The finding, reported in The Journal of Nuclear Medicine , is important for patients with suspected prostate cancer that has not been confirmed by standard biopsy. The study...Read more

2015 11 Jun

Researchers have developed a molecular imaging technique that could save lives by revealing troublesome thrombi, or blood clots. Their work was presented at the 2015 annual meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI).   "Thrombosis is the underlying cause of deadly diseases such as stroke, pulmonary embolism, deep vein...Read more
