Mammography's alleged harms: Separating fact from fiction

Screening mammography is a tool that has been proved to reduce breast cancer death rates, but its effectiveness continues to be disputed by researchers, some of whom have resorted to guesswork to buttress their arguments, according to an opinion piece by mammography experts Dr. László Tabár and Dr. Peter B. Dean.

Analysis of Swedish county data is off the mark

In this week's study in the Journal of the National Cancer Institute, a research team claimed to find that mammography screening had no impact on mortality from breast cancer, based on their interpretation of data from Swedish counties. However, the group made a number of fatal mistakes in their analysis, according to Dr. László Tabár.

Cardiac stress test imaging comparison showing DeepAC and CT-based attenuation correction scans for two patients with quantitative perfusion data.

AI-driven cardiac PET attenuation correction shows promise

The algorithm could offer a “practical alternative in cardiac PET,” researchers noted.

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).

The left panel shows F-18 SynVesT-1 PET distribution volume (VT) maps of the brain and spinal cord in a naïve control mouse and a mouse with experimental autoimmune encephalomyelitis (EAE), a model of multiple sclerosis. The right panel shows Cu-11 UCB-J PET images of the brain of a 46-year-old male healthy control (left) and 43-year-old female MS patient (right).

AI approach could improve DBT efficiency

AI-based slab reconstruction may help improve screening DBT workflows while not compromising on image quality.

June 2, 2026

Slab reconstruction provides visualization of subtle architectural distortion similar to that of standard 1-mm slices in a false-positive screening exam. Images include breast exams from a 45-year-old woman who underwent screening mammography. Craniocaudal tomosynthesis images with (A) 1-mm slices and (B) 6-mm slab reconstructions show an area of architectural distortion in the subareolar region of the left breast (arrow). (C) Targeted ultrasound imaging shows a corresponding irregular hypoechoic mass (arrow), which was subsequently biopsied. Pathologic examination revealed a sclerosing papillary lesion.
