Representative axial T1-weighted spin-echo thigh MRI scans in (A) a 61-year-old female participant and (B) a 62-year-old female participant. Both participants were of similar age and body mass index (BMI, calculated as weight in kilograms divided by height in meters squared). Both had Physical Activity Scale for the Elderly scores above the mean score in the study. According to the World Health Organization definition, the participant in B qualified as having abdominal obesity (abdominal circumference ≥ 88 cm). Abdominal circumference is a measure of central obesity that captures fat distribution and serves as an indicator of cardiometabolic health. Compared with the participant in A, the participant in B had a higher proportion of ultra-processed food (UPF) in their diet (87.1% vs 29.5%) and exhibited fattier thigh muscles bilaterally, with Goutallier grade (GG) for all thigh muscles summing to 25 for the participant in A and 38 for the participant in B.

MRI highlights worse muscle health from ultra-processed foods

A study has found that ultra-processed food consumption is tied to higher thigh-muscle fat infiltration on MRI.

Post-neoadjuvant chemotherapy (NAC) MRI scans in a 66-year-old woman with invasive breast cancer show a lesion that appears fragmented in the first postcontrast axial T1-weighted image (arrow in A) but becomes more conspicuous and homogeneous in the last delayed phase (arrow in B). Despite these visual differences, response classification was identical between abbreviated and full diagnostic MRI. Pathologic analysis confirmed a partial response with residual invasive carcinoma.
