Functional MRI assists in somatosensory cortex
Researchers from the U.K. and Germany have used ultrahigh-field functional MRI to produce a precise topographic map of the representation of touch in area 3b of the somatosensory cortex -- a region thought to only respond to mechanical stimulation.

Functional MRI sheds new light on sound and touch
Researchers in the U.S. and the Netherlands have observed auditory responses in the human somatosensory cortex, a region of the brain usually dedicated to processing touch. They measured functional MRI signal changes following a frequency discrimination task.

Right breast, 10 o’clock position, same patient: A 15 mm irregular hypoechoic solid lesion with suspicious morphology, situated approximately 6 mm from the index lesion. Biopsy confirmed invasive ductal carcinoma, Grade 2, ER positive, PR positive, HER2 positive, concordant with ultrasound features. Findings are in keeping with multifocal invasive ductal carcinoma in a heterogeneously dense breast. The patient was referred for surgical management.
Italian team seeks to optimize imaging of pelvic floor dysfunction

Sagittal T2-weighted MRD image at maximal pelvic floor contraction (squeeze). The pubococcygeal line (PCL) serves as a reference line extending from the inferior border of the pubic symphysis to the last coccygeal joint. The H line represents the anteroposterior dimension of the levator hiatus, while the M line measures the perpendicular descent of the levator plate relative to the PCL. The midpubic line (MPL) provides an additional reference for anterior-posterior alignment. Identifiable pelvic structures include the pubic symphysis (Ps), rectum (R), and bladder (B).
