Delayed SPECT improves prostate cancer detection
May 26, 2023 -- Delaying SPECT/CT imaging by 15 hours after radiotracer injection can enable the identification of more tumors in patients with relapsed prostate cancer, according to a study published May 25 in the Journal of Nuclear Medicine. Read More
PSMA-PET/CT is cost-effective over standard prostate cancer imaging
May 25, 2023 -- A cost analysis has demonstrated that prostate-specific membrane antigen (PSMA)-PET/CT imaging with F-18 DCFPyL radiotracer should be considered as an alternative to standard imaging for prostate cancer staging, according to a group in New York. Read More
Nomogram predicts relapse in prostate cancer patients
May 24, 2023 -- A nomogram can help predict relapse in patients with prostate cancer who undergo prostate-specific membrane antigen (PSMA)-PET-guided radiotherapy after prostatectomy, according to a study published May 23 in JAMA Network Open. Read More
PET reveals thermal burns due to multiple ICD shocks
May 23, 2023 -- PET imaging has shown for the first time that multiple shocks from implantable cardioverter defibrillators (ICDs) can result in subcutaneous tissue burns, according to a report published May 18 in HeartRhythm Case Reports. Read More
Tau PET adds certainty when diagnosing Alzheimer's disease
May 23, 2023 -- Tau PET scans can help diagnose Alzheimer's disease on top of extensive clinical work-ups in participants with cognitive symptoms, according to a study published May 22 in JAMA Neurology. Read More
Can automated PET tracer radiosynthesis replace manual methods?
May 23, 2023 -- Researchers have developed a new process for automatically synthesizing zirconium-89 (Zr-89)-based PET radiotracers -- a step that can facilitate larger numbers of scans in cancer patients in clinical trials, according to the group. Read More
Radiation exposure among interventionalists is low, but varies widely
May 22, 2023 -- Radiation exposure is generally low among interventional radiologists who perform stroke treatments, yet shows a wide range, underscoring that further work is needed to keep doses as low as possible, a German team has found. Read More
PET reveals effects of brain stimulation in coma patients
May 19, 2023 -- PET imaging has revealed that trigeminal nerve stimulation (TNS) increases brain metabolism and may promote recovery in vegetative or minimally conscious patients, according to a study published May 12 in Brain Stimulation. Read More
SPECT reduces kidney imaging times in children
May 17, 2023 -- Shorter scan times of five minutes during kidney imaging in children are feasible using newer SPECT cameras with cadmium-zinc-telluride (CZT) detectors, according to a study published May 15 in Pediatric Radiology. Read More
PET/CT fluoroscopy feasible during liver ablations, study finds
May 15, 2023 -- A research group from Brigham and Women's Hospital in Boston has found that PET/CT fluoroscopy is feasible and has the potential to assist doctors performing PET/CT-guided tumor ablations. Read More
