Jude Dineley, PhD[email protected]Nuclear MedicineUltralow-dose CT enables PET correctionThe use of ultralow-dose CT scans for attenuation correction and respiratory gating of PET scans is feasible, concluded a recent study published in Physics in Medicine and Biology. Doses an order of magnitude lower than existing low-dose CT protocols on PET/CT scanners were achieved.February 12, 2012Nuclear MedicineFully automated gating: A new era for PET?A fully automated algorithm that can extract a respiratory signal from raw PET data has the potential to make gating a more convenient -- and, therefore, more widely adopted -- utility in clinical PET, according to an article published in Medical Physics.November 24, 2010Page 1 of 1Top StoriesMRIUnstable brain networks may drive multiple sclerosis fatigueFatigue affects between 36.5% and 78% of people with multiple sclerosis and can dramatically impair their daily lives.Womens ImagingAI-calculated BAC on mammograms predicts cardiovascular disease in womenCardiac ImagingECR: Cardiac imaging is at the 'heart' of precision medicineUltrasoundUltrasound MinnieCast, Episode 3: Focused ultrasound brings hope to patientsWomens ImagingECR: LLMs help patients understand breast imaging reports

The CT image is shown in the axial plane. The PMV is automatically extracted using the developed deep learning model and overlayed onto the lungs for visual clarity.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/03/genkin.25LqljVF0y.jpg?auto=format%2Ccompress&crop=focalpoint&dpr=2&fit=crop&h=167&q=70&w=250)
