C-index for Cox regression and random survival forests models using two feature sets. Adding historical registry data decreases the C-index for Cox regression but increased it for the random survival forests model, consistent with the non-linear structure in the registry data.

fMRI reveals postmenopausal brain connectivity shifts in midlife women

By Kate Madden Yee

The findings suggest that menopause represents "an important neurological transition," researchers noted.

June 9, 2026

Network-level analysis comparing functional association strength between ROIs of pre- and postmenopausal groups. Lower levels of connectivity were identified among one cluster (F3,106 = 8.84, Puncorrected < 0.001, PFDR = 0.012) in the postmenopausal group, which included the right supramarginal gyrus anterior division, right planum temporale, and right Heschl’s gyrus, among others. FDR, false discovery rate; ROI, region of interest.

MRI finds perfusion defects across a range of lung impairments

By Kate Madden Yee

Impaired lung function is associated with increased pulmonary perfusion defects detectable by a particular MRI technique.

Caption: Representative images show emphysema and functional lung maps derived by CT and PREFUL-MRI: (A–C) CT-derived emphysema images, (D–F) perfusion maps, (G–I) regional ventilation maps, (J–L) flow-volume loop correlation metric maps, (M–O) ventilation/perfusion combined parameter maps. (A, D, G, J, M) Images in a 63-year-old male with normal spirometry: FEV1%pred = 89.0%, FEV1/FVC = 0.73; emphysema percentage = 0.2%, QDP = 7%, VDPRVent = 2%, VDPFVL-CM = 1%. (B, E, H, K, N) Images in a 65-year-old female with PRISm + RP: FEV1%pred = 71.2%, FVC %pred = 76.8%, FEV1/FVC = 0.76; emphysema percentage = 4.7%, QDP = 10%, VD-PRVent = 18%, VDPFVL-CM = 6%. (C, F, I, L, O) Images in a 57-year-old male with AO: FEV1%pred = 56.8%, FEV1/FVC = 0.52; emphysema = 11.1%, QDP = 31%, VDPRVent = 33%, VDPFVL-CM = 41%. AO = airflow obstruction, FEV1 = forced expiratory volume in 1 second, FVC = forced vital capacity, FVL-CM = flow-volume loop correlation metric, %pred = percent predicted, PREFUL = phase-resolved function lung, PRISm = preserved ratio impaired spirometry, QDP = perfusion defect percentage, RVent = regional ventilation, VDP = ventilation defect percentage.

Image-guided focal laser ablation effective for prostate cancer

By Amerigo Allegretto

MRI-directed, ultrasound-guided TPLA may be a promising technique to treat prostate cancer while avoiding radical therapies.

June 3, 2026

Preablation, postablation, and recurrence multiparametric MRI scans depict a 63-year-old man treated with transperineal focal laser ablation (TPLA) for localized prostate cancer. Clinical parameters included an initial prostate-specific antigen (PSA) level of 7.2 ng/mL, a Prostate Imaging Reporting and Data System (PI-RADS) grade 4 lesion (red circles) in the right apical peripheral zone, and a maximum tumor length of 5 mm. MRI-guided targeted biopsy confirmed a Gleason score 3+4 prostate cancer tumor. (A) Pre-ablation axial T2-weighted MRI scan and apparent diffusion coefficient (ADC) image shows the apical PI-RADS 4 lesion (circles). (B) Six-month post-ablation axial T2-weighted MRI scan and ADC image show cystic necrosis (arrows). There was no evidence of recurrence; the PSA level was 1.5 ng/mL. (C) One-year after ablation, the patient’s PSA level had increased to 4.3 ng/mL. Axial T2-weighted MRI scan and the ADC image shows a recurrent lesion (blue circles) in the right apical peripheral zone adjacent to the ablation scar. Targeted biopsy confirmed Gleason score 3+4 prostate cancer, which was classified as in-field recurrence of clinically significant prostate cancer and subsequently re-treated with TPLA. In summary, serial multiplanar MRI demonstrates treatment response after TPLA with post-ablation necrosis, followed by MRI-detected IFR confirmed with biopsy at 12-month follow-up. Multiparametric MRI was performed with a 3.0-T MRI scanner (Skyra; Siemens Healthineers) using T2-weighted, diffusion-weighted, and ADC sequences, with gadobenate dimeglumine contrast material administration (Bracco Diagnostics).
