PET Scan after Chemo Could Avoid Need for Radiotherapy

2015 23 Apr

A positron-emission tomography (PET) scan immediately after treatment with chemotherapy can identify patients who have a very good outcome without additional radiotherapy, according to a study published in the New England Journal of Medicine . The "RAPID" trial involved 602 Hodgkin lymphoma patients who had a PET scan performed after their chemotherapy.... Read more

Noninvasive Imaging of Immune System Detects Tumours

2015 22 Apr

A new technique that allows real-time, noninvasive imaging of the immune system’s response to the presence of tumours offers a potential breakthrough both in diagnostics and in monitoring efficacy of cancer therapies. Developed in the lab of Whitehead Institute Member Hidde Ploegh, the method utilises the imaging power of positron emission tomography... Read more

1 Nanoparticle = 6 Types of Medical Imaging

2015 22 Jan

Researchers have created a nanoparticle that can be detected by six medical imaging techniques: computed tomography (CT) scanning, positron emission tomography (PET) scanning, fluorescence imaging, photoacoustic imaging, upconversion imaging and Cerenkov luminescence imaging. In the future, patients could receive a single injection of the nanoparticles... Read more

Live Coverage of the Immune System at Work via PET Imaging

2015 20 Jan

Researchers at Tübingen University have developed a new technique to safely mark T-cells for non-invasive in vivo imaging to better understand what happens during immune reactions in the body. This technique enabled the investigators to track the T-cell movement in mice using positron emission technology (PET). Previous methods used to follow the movement... Read more

RSNA 2014: An Imaging Biomarker of Alzheimer’s Disease?

2014 01 Dec

Based on findings of a new study, changes in brain connections visible on MRI could represent an imaging biomarker of Alzheimer's disease, the most common form of dementia. For this study, researchers examined the brain's structural connectome, a map of white matter tracts that carry signals between different areas of the brain. "The structural connectome... Read more

RSNA 2014: PET/CT Shows Pituitary Problems in Veterans with PTSD

2014 01 Dec

According to researchers, hybrid imaging with positron emission tomography and computed tomography (PET/CT) in the brain's pituitary region may be an effective method to differentiate military veterans with post-traumatic stress disorder (PTSD) from those with mild traumatic brain injury (MTBI). MTBI involves damage to the brain from an external force,... Read more

Bioimpedance Technique Enhances PET Scan Accuracy

2014 20 Oct

A recent study at the University of Eastern Finland (UEF) has developed a new technique based on bioimpedance that reduces image degradation caused by respiratory motion during a positron emission tomography (PET) scan. The novel technique allows for image reconstruction at a specific phase of the patient's breathing pattern, making it possible to reduce... Read more
