Patient position affects radiation exposure during PET/CT scans
Arm position is a significant factor influencing radiation exposure to patients during whole-body PET/CT scans, according to a team of radiologic technologists in Japan.The finding underscores the importance of considering these factors when evaluating radiation exposure in clinical practice, noted lead author Ken Takada, PhD, of Ogaki Municipal Hospital in Ogaki City, and colleagues.“These findings contribute to a better understanding of the radiation dosimetry associated with different patient positions during WB-PET/CT scans,” the group wrote, in an article published January 4 in Radiography.Generally, to optimize i...

Lung Cancer CT Screening Can Save Lives, But Study Finds Downsides
WEDNESDAY, Jan. 3, 2024 -- Numerous studies have confirmed that annual lung cancer screening using CT scans does save lives. However, new data has emerged showing that scans often pick up abnormalities that lead to follow-up invasive tests -- and... (Source: Drugs.com - Daily MedNews)

PET/CT predicts brain tumors in melanoma patients
PET/CT scans have the potential to predict brain metastasis in melanoma patients, according to a study published December 26 in Cancers.
In a retrospective study, a team at the University Hospital Salzburg in Austria studied baseline F-18 FDG-PET/CT imaging parameters in patients with melanoma and found they were associated with the development of metastatic brain tumors.
“In melanoma patients, identification of those who are at higher risk of brain metastasis occurrence can be crucial as subsequent surveillance and even prophylactic treatment options can be provided,” wrote lead author and nuclear medicine physician...

PET/CT scans ‘crucial’ in patients with NK/T-cell lymphoma
PET/CT has significant advantages over conventional methods for lesion detection and staging in patients with natural killer/T-cell lymphoma, according to a study published December 18 in Heliyon.In a retrospective analysis, a team in Taiyuan, China, found that F-18 FDG-PET/CT was superior for analyzing imaging manifestations of NK/T-cell lymphoma and suggested that the scans can improve treatment plans for patients.“F-18 FDG-PET/CT scanning is crucial in identifying tumor lesions, determining staging, and devising treatment strategies for individuals diagnosed with NK/T-cell lymphoma,” wrote lead author Huixia Geng, M...

AI predicts cardiovascular disease mortality risk on chest CT
A deep-learning algorithm could predict a patient’s risk of atherosclerotic cardiovascular disease (ASCVD) from analysis of noncontrast-enhanced chest CT exams, according to a study presented at the recent RSNA meeting. Researchers, led by presenter Vineet Kalathur Raghu, PhD, from Harvard Medical School and Massachusetts General Hospital, trained an AI model to predict a patient’s probability of cardiovascular mortality within 12 years. In testing, the algorithm yielded a statistically significant improvement in prediction performance over a baseline regression model. The algorithm, called CT-CV-Risk, also predicte...

Lymphoscintigraphy underused in the U.S. to diagnose lymphedema
Lymphoscintigraphy (LSG) is recommended but seldom used to diagnose lymphedema in real-world settings in the U.S., according to a study published on December 14 the Journal of Vascular Surgery: Venous and Lymphatic Disorders.The finding comes despite guidelines recommending LSG as the diagnostic test of choice and underlines the need for a better diagnostic test, wrote lead author Tina Moon, MD, of Tufts Medical Center in Boston and colleagues.“Optimal management of [lymphedema] requires a timely and accurate diagnosis to provide relief of the symptoms of heaviness and aching as well as reducing the risk of infection,”...
