FDG-PET shows where exercise could stall Alzheimer's
People with sedentary lifestyles who exercised regularly over several months showed increased brain glucose metabolism on FDG-PET in one brain region associated with the early onset of dementia or Alzheimer's disease, according to a study published online February 3 in Brain Plasticity.

MRI scoring system improves ovarian cancer detection
Researchers from France and the U.K. have developed an MRI-based, five-point scoring system that can distinguish between malignant and benign ovarian cysts with an accuracy of 90% when ultrasound exams are inconclusive, according to a study published January 24 in JAMA Network Open.

MRI data show smoking, alcohol age the brain
It is no secret that excessive smoking and alcohol consumption harm one's health. Now, MR images and a machine-learning metric show that these bad habits also can age the brain prematurely, according to a study published online on January 30 in Scientific Reports.

No signs of residual gadolinium after MR arthrography
No signs of residual gadolinium uptake in the brain were found following intra-articular administration of a gadolinium-based contrast agent (GBCA) for MR arthrography in a new study, published online January 25 in Skeletal Radiology. The findings indicate that residual gadolinium may not occur with intra-articular use.

Deep learning could help MS patients avoid GBCA MRI
With the aid of a deep-learning model, a team of researchers has detected with greater than 70% accuracy active lesions in patients with multiple sclerosis (MS), potentially helping them avoid repeat MRI scans and multiple doses of gadolinium-based contrast agents (GBCAs), according to a study published in the February issue of Radiology.

MRI shows air pollution effect on kids' brain development
Air pollution is not only bad for the lungs, it could be bad for the brain as well -- especially in children. Brain MR images showed reduced gray-matter volume in kids who were exposed to high levels of traffic-related air pollution since birth, according to a January 24 study in PLOS One.

CT, MRI for lower back pain still prevalent in ED
The rate of CT and MRI scans for back pain remained steady from 2001 to 2016 despite efforts to curtail unnecessary imaging tests in emergency departments (EDs) for lower back pain, according to a study published in the February issue of the American Journal of Roentgenology.

Adding MBI to DBT finds more breast cancers
By Amerigo Allegretto
Adding molecular breast imaging (MBI) to DBT screening leads to more invasive cancers detected in women with dense breasts.
September 23, 2025
Images in a 62-year-old woman who presented for screening. (A) Image from DBT screening (the synthesized 2D mediolateral oblique view of the left breast is shown) at year on was interpreted as negative and showing heterogeneously dense breast. (B) Image from molecular breast imaging screening (mediolateral oblique view) at year one reveals a 0.9-cm non-mass focal area of uptake in the left breast (arrow). (C) Targeted ultrasound scan (transverse image) shows a suspicious mass in the 3-o’clock position of the left breast, 4 cm from the nipple. Ultrasound-guided core biopsy and lumpectomy revealed a 0.9-cm grade 2 invasive ductal carcinoma, an estrogen receptor–negative, progesterone receptor–negative, human epidermal growth factor receptor 2–negative lesion, with two sentinel nodes negative (N0).

An example of a typical BgRT plan: A) PET scan on diagnostic PET/CT and B) X1 PET-Linac for patient #15 with a PET avid rib metastasis with GTV size= 3.1 cc, PTV = GTV + 5mm, BTZ (biological tracking zone) = PTV + 5 mm, AC = 14.33 kBq/mL and NTS = 21.04. Red, magenta, and green contours represent GTV, PTV, and BTZ. C) Dose distribution and D) bounded-DVH of a BgRT plan are displayed for the same patient. The bounded Dose-Volume Histogram (DVH) models variations in BgRT delivery, encompassing fluctuation in target background signal variation, target localization and dose delivery uncertainties.
