PET/MRI with DWI is best option to evaluate lymphomas
January 28, 2016 -- In the largest study of its kind to date, Austrian researchers have found that adding diffusion-weighted imaging (DWI) to FDG-PET/MRI can enhance the evaluation of patients with lymphoma, according to a study published online in Investigative Radiology.
Munich team shows promise of 3D in vivo skin mapping
January 21, 2016 -- Diagnosis of skin cancer currently requires a biopsy, which is costly, often causes permanent scarring, and may expose the patient to the risk of infection. New German research suggests optical imaging technologies may provide a viable, noninvasive alternative.
Global survey puts renewed emphasis on dose
January 8, 2016 -- European hospitals perform nuclear cardiology at lower doses than the rest of the world, and they use more of the best practices that have been identified, according to the results of a global survey published in the European Journal of Nuclear Medicine and Molecular Imaging.
Optical imager targets breast cancer screening
December 31, 2015 -- Diffuse optical imaging has been proposed as a nonionizing and relatively inexpensive alternative method for detecting breast cancers, including those in dense tissues. Now, U.S. scientists have developed a handheld optical scanner with the potential to image breast cancer in real-time.
Raman imaging steps closer to the clinic
December 28, 2015 -- For brain tumor patients undergoing surgery, the proportion of tumor removed is a major factor determining prognosis. However, diseased tissue may look like healthy brain, making it difficult for surgeons to locate the tumor margin.
PET features help guide dose escalation
December 18, 2015 -- Quantitative imaging features (QIFs) from FDG-PET combined with conventional prognostic factors of patients with non-small cell lung cancer (NSCLC) show potential to enhance overall survival risk stratification. That's the conclusion of study findings published in the Red Journal and Radiology.
Positron emission mammo shows prowess in cancer
December 14, 2015 -- Positron emission mammography (PEM) can detect almost all breast cancer index lesions located within its scanning range without limitations due to tumor size, grade, or histological subtype, according to a Dutch study presented at RSNA 2015 in Chicago.
EANM casts doubt on new hybrid imaging society
December 14, 2015 -- Concerns have been raised by the president of the European Association of Nuclear Medicine (EANM), Dr. Arturo Chiti, about the risk of duplicating efforts in the emerging field of hybrid imaging, after the recent announcement of the formation of a new hybrid imaging society.
Small fluorescent dye eases NIR-II imaging
December 11, 2015 -- Researchers are reporting on the first small-molecule fluorescent dye for "near-infrared-II" (NIR-II) imaging. The dye, which is rapidly excreted by the body, could be used to image tumors in vivo and for image-guided surgery and therapy (Nature Materials, 23 November 2015).
Beam-on PET tracks proton dose in real-time
November 26, 2015 -- Exploiting the superior dose deposition of particle therapy for clinical benefit necessitates an accurate technique for verifying dose delivery. Because the treatment beam stops inside the patient, such monitoring requires detection of secondary radiation created when the incident beam interacts with the tissue, Dutch researchers found.
