PET moves ahead in detection of hypoxic tumors
October 21, 2020 -- Researchers have used PET to provide a new way to diagnose hypoxia in tumors. They demonstrated that signs of tumor hypoxia can be spotted among the gamma rays collected routinely during a PET scan, providing clinicians with extra information to guide treatment decisions.

German group refines PET technique for prostate cancer
October 13, 2020 -- Researchers from Essen have used a PET-based optical imaging method known as Cerenkov luminescence imaging to highlight the presence of cancer cells after prostate cancer surgery. They published their results in the October edition of the Journal of Nuclear Medicine. Read More
Compton imaging opens up new diagnostic avenues
October 9, 2020 -- Compton imaging -- originally developed by astronomers for detecting gamma ray sources -- is now under investigation for clinical imaging. A high-performance Compton camera could prove invaluable for applications within nuclear medicine and molecular imaging, researchers have found. Read More
600+ km trek across the Himalayas for cancer therapy
September 23, 2020 -- It takes on average 18 hours by bus for patients to reach the cancer hospital in Nepal, and many of them travel over 600 km. Now the pandemic has made it even more difficult to get treatment, writes Tirthraj Adhikari, a medical physicist trained in Italy. He gives a personal account of the challenges faced by patients and staff. Read More
After Brexit: Device regulations come under scrutiny
September 15, 2020 -- The U.K. has produced advice on how to launch medical devices on the market after the Brexit transition period ends on 1 January 2021. Regulatory expert Mike Pogose discusses how the new procedures will affect imaging manufacturers and their customers. Read More
Dutch team unveils new findings on radiomics
September 14, 2020 -- Researchers from Amsterdam have found that molecular imaging can contribute to better treatment decisions for patients with head and neck squamous cell carcinoma by providing clinically valuable radiomics information on tumor phenotypes. Read More
European investigators shine new light on endocarditis
September 9, 2020 -- The diagnosis of infective endocarditis remains a serious clinical challenge, but F-18 FDG PET/CT is making progress and can be an extremely useful modality in these patients, with good sensitivity and specificity, three different research groups from Portugal, France, and Italy reported at the recent European Society of Cardiology virtual congress.

Post-treatment SPECT/CT monitors radionuclide dose
September 7, 2020 -- A research group from the Peter MacCallum Cancer Center in Melbourne, Australia, has pioneered a technique that uses a follow-up SPECT/CT examination after radionuclide therapy to personalize the radiation dose delivered to a patient. Read More
German investigators highlight clinical value of PET/MRI
September 3, 2020 -- In a study of more than 1,000 examinations, German researchers found that PET/MRI improved lesion detection by over 15% compared with PET/CT in malignant bone disease and lung cancer. Also, PET/MRI reduced ionizing radiation by nearly 80% when compared with PET/CT. Read More
What must radiologists know about the abscopal effect?
August 26, 2020 -- The abscopal effect occurs when radiation treatment -- or another type of local therapy -- not only shrinks the targeted tumor but also leads to the shrinkage of untreated tumors elsewhere in the body. History columnist Dr. Adrian Thomas reflects on its origins and future potential. Read More
