Study Type: Commentary/opinion piece (career development focus in AJR)

Key Question: How can radiologists effectively negotiate career opportunities and terms (e.g., contracts, promotions, compensation)?

Key Findings: Not determinable — no abstract text was supplied, so specific data, strategies, or outcomes cannot be summarised.

Clinical Relevance: Career negotiation skills are increasingly relevant to UK radiology consultants and trainees navigating job planning, private practice, and academic contracts within NHS and mixed-sector arrangements.

Limitations: No abstract was provided; this summary is based solely on the title and cannot reflect the article's actual content, evidence base, or conclusions. *Please provide the full abstract text for an accurate, evidence-based structured summary.*

Study Type: Expert panel narrative review

Key Question: What is the current evidence base, and what are the benefits and risks, of whole-body MRI (WB-MRI) screening in asymptomatic individuals?

Key Findings:

• WB-MRI is increasingly used commercially for multicancer and nononcologic screening (e.g., aneurysm detection, body composition, musculoskeletal assessment) despite absence of clinical guidelines endorsing population-level use.
• Evidence to date is largely limited to detection frequencies rather than outcomes data (mortality, morbidity, cost-effectiveness).
• Key harms include overdiagnosis/overtreatment of indolent disease, downstream costs from indeterminate findings, and unregulated commercial marketing raising informed consent and psychosocial concerns.

Clinical Relevance: As commercial WB-MRI screening expands in the UK, radiologists should understand its unproven benefit-harm balance to inform patient counselling, referral triage, and departmental policy on incidental findings management.

Limitations: As a narrative expert review rather than systematic synthesis, conclusions rely on selective evidence and expert opinion rather than pooled quantitative data.

Study Type: Retrospective cohort study (single-centre, real-world, non-trial setting)

Key Question: Does upfront biparametric MRI screening for prostate cancer outperform a simulated PSA-triggered pathway in asymptomatic Korean men undergoing routine health check-ups?

Key Findings:

• Among 618 men (median PSA 0.98 ng/mL), 13.4% were PI-RADS ≥3, with only 1.5% (9/618) diagnosed with clinically significant prostate cancer (csPCa).
• A simulated PSA-triggered pathway (PSA >3.0 ng/mL) would have avoided 90% of MRI scans and 70% of unnecessary biopsies, missing only 1 csPCa case overall.
• In the PROSA-trial-eligible subgroup (n=442), PSA-gating avoided ~89% of MRIs and 68% of biopsy consultations without missing any of 5 csPCa cases.

Clinical Relevance: These findings caution against extrapolating upfront-MRI screening protocols (validated in Western trial populations) to lower-incidence Asian populations, supporting continued PSA-based triage to avoid resource strain within NHS imaging and biopsy services.

Limitations: Retrospective, single-centre design with simulated (not actual) comparison of PSA-triggered pathway, limiting causal and generalisability conclusions.

Study Type: Retrospective cohort study (propensity-weighted national claims analysis)

Key Question: Does the short-term safety profile of uterine fibroid embolization (UFE) differ from myomectomy when analysed by surgical subtype rather than pooled together?

Key Findings:

• 30-day major adverse events were lower with UFE (2.5%) than abdominal (5.4%, OR 0.44) or laparoscopic myomectomy (2.5%, OR 0.77), but higher than hysteroscopic myomectomy (1.0%, OR 1.95).
• UFE showed lower readmission and bleeding rates versus incisional approaches, but higher ED visit rates across all myomectomy comparators (OR 1.30–2.38).
• Pooling all myomectomy subtypes masked these differences, showing no significant overall difference versus UFE (OR 1.14).

Clinical Relevance: For UK MDTs counselling patients on uterus-preserving fibroid treatment, this highlights that UFE's safety advantage is subtype-dependent—greatest versus abdominal myomectomy but absent versus hysteroscopic myomectomy—informing more nuanced, procedure-specific risk discussions.

Limitations: Claims-based data lack clinical granularity (e.g., fibroid size/number, indication, complication severity) and residual confounding despite propensity weighting.

Study Type: Cannot be determined; likely a commentary/editorial given the title and journal format, but insufficient information to confirm.

Key Question: Unable to determine—no abstract text was supplied.

Key Findings: Not available; no data or content provided to summarise.

Clinical Relevance: Cannot be assessed without access to the article's content.

Limitations: The absence of an abstract precludes any meaningful clinical appraisal; the full text would need to be reviewed to produce an accurate summary.

Study Type: Narrative review (Special Series Review)

Key Question: Can fibroblast activation protein (FAP)-directed PET imaging be applied beyond oncology to assess fibrotic and inflammatory disease activity?

Key Findings:

• FAP is upregulated in activated fibroblasts across non-malignant conditions involving tissue remodeling, including ischemic and non-ischemic cardiomyopathy, valvular disease, atherosclerosis, vasculitis, aneurysms, interstitial lung disease, inflammatory arthritis, and IgG4-related disease.
• Early exploratory studies suggest FAP-PET may act as a biomarker of active fibrotic/inflammatory processes in these conditions, though robust clinical validation is lacking.
• FAP-targeted radiopharmaceutical therapies and CAR-T approaches are being explored preclinically for non-oncologic fibrotic disease.

Clinical Relevance: FAP-PET could offer NHS radiology and cardiology services a novel, non-invasive tool for monitoring fibrotic and inflammatory disease activity across multiple specialties, potentially informing future multiparametric imaging pathways.

Limitations: Evidence is derived largely from small, early-phase, exploratory studies without established diagnostic accuracy or outcome data.

Study Type: Systematic review and meta-analysis (5 observational studies, n=133)

Key Question: What is the prevalence and regional distribution of late gadolinium enhancement (LGE) on cardiac MRI in patients with mitochondrial myopathy?

Key Findings:

• Pooled LGE prevalence was 20.72% (95% CI: 5.63–41.00%), with substantial heterogeneity (I² = 81.1%)
• Inferolateral wall was the most commonly affected region (8.47%, 95% CI: 0.60–21.65%), followed by other locations (4.93%) and septum (2.76%, least frequent)

Clinical Relevance: CMR with LGE may help detect subclinical myocardial fibrosis in mitochondrial myopathy patients referred to UK cardiac imaging services, supporting earlier identification of cardiac involvement in this rare disease group.

Limitations: Small number of studies and patients, with high statistical heterogeneity, limits confidence in pooled estimates and precludes conclusions on prognostic significance.

Study Type: Prospective substudy of a randomised controlled trial

Key Question: Can single-slice quantitative thigh MRI serve as a surrogate marker for whole-body composition and detect fasting-induced changes in muscle and fat?

Key Findings:

• Extensor thigh muscle area strongly predicted whole-body muscle mass on both wbMRI and BIA (R²=0.77 and 0.72 respectively).
• Thigh fat fraction and intermuscular adipose tissue were only weak-to-moderate predictors of visceral fat volume (R²=0.15–0.43).
• No statistically significant fasting-related changes in muscle area, fat fraction, or intermuscular fat were seen versus controls (all P≥0.45).

Clinical Relevance: Single-slice thigh MRI could offer a simplified, lower-cost surrogate for whole-body muscle mass assessment relevant to sarcopenia and metabolic research within NHS imaging protocols, though it is unsuitable for tracking visceral fat or short-term dietary intervention effects.

Limitations: Small sample size (n=66) over a short one-month intervention limits power to detect subtle body composition changes.
