SIIM: LLMs can reliably perform numerical tasks in radiology

A study presented at SIIM 2026 showed how LLMs can perform well on numerical tasks in radiology.

PET/CT images performed at 10- and 60-minutes following injection of Ga-68 FAPI-46 (mean 181 MBq; range 143–225 MBq).

Early FAPI-PET scans match 60-minute scans for lung cancer staging

SIIM: LLMs have tradeoffs in energy use for imaging tasks

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.

X-ray score linked to hip fracture risk in the elderly

Abdominal aortic calcification (AAC) scores of 5 or higher were significantly associated with hip fractures.

June 8, 2026

Abdominal aortic calcification (AAC) score grading: 0 - no calcific deposits in front of the vertebrae; 1 - small scattered calcific deposits filling less than 1/3 of the longitudinal wall of the aorta; 2 - 1/3-2/3 of the wall calcified; 3 - 2/3 or more of the wall calcified.

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.

(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%.

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.

AI detects lung cancer nodules well but shows low specificity

By Kate Madden Yee

The finding suggests the models offer “a potential role as adjunctive tools for ruling out malignancy” rather than classifying it.

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).
