A 21-year-old college student’s severe headaches were initially dismissed as stress during finals, but an MRI revealed a two-inch benign brain tumor pressing on the left frontal cortex. She underwent a six-hour craniotomy to remove it and is now preparing for radiation therapy to prevent regrowth, urging others to trust their gut and seek second opinions if symptoms persist.
A Minnesota-led study with 107 adults found that alcohol at a driving-penalty level increases local brain connectivity and clustering while reducing global connectivity, making brain regions more insular. These network changes measured by MRI after rest predict subjective intoxication and may explain common alcohol effects like visual and motor impairment; effects vary by individual and health status, with broader implications for understanding alcohol's impact on brain communication.
Twins ace Joe Ryan was scratched from a Grapefruit League start with right-side lower back tightness and is undergoing an MRI to assess the injury, leaving questions about Minnesota's rotation after Pablo López's Tommy John surgery; depending on MRI results, Ryan's spring ramp-up and potential World Baseball Classic involvement could be affected. He posted a 3.42 ERA over 171 innings last season and remains under team control through 2027.
A 12-month randomized trial found that healthy adults who followed a structured aerobic program (about 150 minutes per week) had brains that appeared roughly 0.6 years younger on MRI than those who did not, with the difference approaching a full year. The change was modest and not explained by a single measured factor, suggesting multiple potential mechanisms. While larger studies are needed to link brain-age reductions to dementia risk, the findings support following current exercise guidelines to help keep the brain biologically younger into midlife.
Twins right-hander Pablo López was sent for an MRI after elbow soreness surfaced during live batting practice, a precaution ahead of spring training. López is coming off a 2025 season shortened by a shoulder strain and forearm discomfort, with no surgery announced. If the MRI reveals an issue, Minnesota could need to adjust its rotation, though López and Joe Ryan headline a deep group of pitching options.
A JAMA Internal Medicine study of 602 adults aged 41–76 found 99% had at least one rotator cuff abnormality on MRI, yet most were asymptomatic. The findings suggest many MRI-detected changes are age-related and not clinically meaningful, prompting clinicians to rethink imaging for shoulder pain and emphasize functional symptoms and conservative care before pursuing MRI or surgery.
A 25,997-person UK MRI study used latent profile analysis to classify body-fat distribution into six patterns. Compared with the leanest group, all non-lean profiles showed lower brain volumes and less gray matter, independent of total fat. Two patterns—pancreatic-predominant and skinny-fat—were most strongly linked to brain aging, white-matter lesions, and cognitive decline, with some sex-specific effects (men showing faster brain aging and women showing links to epilepsy for the pancreatic-predominant type). While higher BMI correlated with brain changes, fat location adds independent risk. The study is cross-sectional and can’t prove causation, but if validated these fat-distribution patterns could inform earlier interventions for neurodegenerative risk.
Luka Doncic left the Lakers’ game against the 76ers with a left hamstring injury and will undergo an MRI to assess the extent of the damage.
In a 22-volunteer MRI study, yawning moved cerebrospinal fluid outward toward the spinal column and carried venous blood with it, freeing space for a surge of arterial blood—over a third more than during deep breathing. The researchers also found a unique yawning signature tied to tongue movement. They suggest yawning may be a brain-maintenance process supporting temperature regulation and waste clearance.
A small MRI study (22 healthy participants) shows yawning shifts cerebrospinal fluid away from the brain and briefly increases arterial inflow, unlike deep breaths. The finding suggests yawning may relate to brain maintenance or cooling, but the results are from a preprint on bioRxiv and not yet peer-reviewed.
A 12-month trial of 130 healthy adults (26–58) found that following WHO guidelines (about 150 minutes/week of moderate-to-vigorous exercise) led to brains that appeared roughly 0.6 years biologically younger on MRI than controls, while those who maintained usual routines looked about 0.35 years older. The difference approached statistical significance but was not itself definitive. The researchers couldn’t pinpoint the exact mechanism, with possibilities including subtle brain-structure changes, inflammation, or vascular factors, and long-term effects remain to be studied.
A UK Biobank study of 61,290 MRI scans used surface-to-surface analysis to link gluteus maximus morphology to type 2 diabetes risk, finding men with T2D tend to have a flattened, atrophied glute, while women show outward bulging from fat deposition. Larger gluteus maximus at baseline linked to lower future diabetes risk after adjusting for age, BMI, and lifestyle. The findings suggest muscle phenotype, not just quantity, matters for diabetes risk and could inform clinical assessments, though MRI-based shape analysis is not scalable for routine care and requires further longitudinal validation.
A large multicohort study of 3,737 cognitively healthy participants with 10,343 MRI scans and 13,460 memory assessments finds episodic memory declines with age are linked to broad brain tissue loss rather than a single region, with stronger effects after age 60 and more pronounced in APOE ε4 carriers; results imply aging-related cognitive decline shares mechanisms with neurodegenerative diseases and may require early, multi-area interventions across the brain.
Milwaukee Bucks star Giannis Antetokounmpo is expected to miss four-to-six weeks after re-aggravating his right calf. He will undergo an MRI, with expectations it will mirror his earlier calf injury. Bucks coach Doc Rivers expressed concern about the recurring issue, and Milwaukee’s playoff chances are fading as they sit 11th in the East. Antetokounmpo finished the game with 22 points, 13 rebounds and seven assists before leaving, with a return targeted for late February/early March.
Giannis Antetokounmpo is expected to miss about four to six weeks with a calf injury after 32 minutes in a 102-100 loss to the Nuggets; an MRI will clarify the damage and a return is anticipated in late February or early March. Milwaukee sit 11th in the Eastern Conference amid a slump as the regular season nears its end around April 12, with coach Doc Rivers defending the decision to keep Giannis in after the early issue and Antetounmpo previously criticizing teammates for the poor form.
