Reading the evidence in diagnostics and medical technology
A test or device is judged by how well it detects a condition, how often it gives false alarms or misses cases, and whether using it improves outcomes for people. Accuracy depends on who is tested and how common the condition is, so a test that performs well in a specialist hospital can perform differently in the community. Check the reference standard, the population studied, the sensitivity and specificity and whether results were confirmed in a separate group.
Evidence from open-access studies
These open-access studies come from PubMed’s best-match results for this heading (papers whose main topic it is), ranked here by citation count, with one recent addition. Each abstract is reproduced in full under its recorded open licence so that you can read the authors’ own words. They illustrate the literature; they are not a systematic summary of it. Citation counts measure attention, not reliability or clinical benefit.

AimsMicrovascular obstruction (MVO) remains a major complication following coronary reperfusion, but its pathogenesis is poorly defined. We evaluated myocardial platelet activation and thrombosis using fluorine-18-labelled GP1 ([18F]GP1) positron emission tomography (PET) in patients with anterior ST-segment elevation myocardial infarction.Methods and resultsIn a single-centre observational cohort study, 100 patients with acute anterior ST-segment elevation myocardial infarction underwent hybrid cardiac [18F]GP1 PET and magnetic resonance (MR) imaging with gadolinium enhancement and repeat imaging at 3-6 months. Myocardial [18F]GP1 uptake was quantified using target-to-background ratio (TBRmax) and percentage myocardial uptake (burden) and compared with MR measures of infarction, MVO and adverse ventricular remodelling. One hundred patients (60 ± 10 years, 91% male) underwent [18F]GP1 PET/MR imaging at a median of 13 days following index presentation. Increased myocardial [18F]GP1 uptake was observed in 44% of participants (TBRmax 1.89 ± 0.50). All 40 patients with MR-defined MVO demonstrated myocardial [18F]GP1 uptake. Myocardial [18F]GP1 uptake burden correlated with (ρ = 0.84; P ConclusionMVO following ST-segment elevation myocardial infarction is universally associated with myocardial platelet activation, extending beyond structural abnormalities identified by cardiac MR. These findings are consistent with an important mechanistic contribution of platelet-mediated microvascular thrombosis to no-reflow and MVO, highlighting a potentially targetable biological pathway in a condition for which effective therapies remain elusive.

PurposeDeep inspiration breath hold (DIBH) is widely used to reduce cardiac dose in left-sided breast radiotherapy. However, the reliability of DIBH at CT simulation, has not been systematically evaluated despite the importance of CT simulation as the basis for treatment planning. We investigated the clinical impact of surface-guided breathing training on DIBH reliability and cardiac dose sparing.MethodsIn this retrospective cohort study, 115 breast cancer patients undergoing DIBH CT simulation were analyzed before and after implementation of surface-guided breathing training using an SGRT system. DIBH performance was quantified by partial lung volume increase (PLVI) and breath-hold variability. Correlations between external surface motion and internal DIBH depth were assessed. Cardiac dose metrics were compared, with a subgroup analysis for patients receiving lymphatic drainage area (LDA) irradiation.ResultsPrior to training, insufficient DIBH CTs-including negative PLVI cases-were observed. After training implementation, all CT scans were acquired in intended breath-hold states, eliminating insufficient DIBH acquisitions. Mean PLVI increased by ~ 9%, and breath-hold variability decreased by ~ 26%. Sternum motion correlated most strongly with PLVI, with multiregion surface monitoring yielding the highest internal correlation. These improvements were reflected in significant reductions in cardiac dose, particularly in the LDA subgroup, with selected heart dose metrics reduced up to 96%, while maintaining target coverage.ConclusionsDIBH at CT simulation with surface-guided breathing training proves to be reliable. The training prevents planning CTs in wrong breathing states and thus enables clinically meaningful cardiac dose reduction in breast radiotherapy.

BackgroundMotion artifacts caused by cardiac pulsation remain a major technical challenge in coronary CT angiography (CCTA). Although an advanced cardiac motion correction (CMC) algorithm has been developed and successfully implemented in clinical practice, the effectiveness of this algorithm in improving coronary image quality in clinical settings has not yet been fully investigated.PurposeTo evaluate the impact and clinical value of a motion correction algorithm on image quality in non-ECG-gated CCTA.MethodsWe retrospectively enrolled 76 patients who underwent CCTA for suspected coronary artery disease. Based on the mean heart rate (HR) recorded during scanning, patients were divided into three groups: low HR (HR ≤ 60 bpm), intermediate HR (60 ResultsAt high HRs, the difference in subjective image quality of the right coronary artery (RCA) between STD and CMC reached statistical significance (p 0.05). However, at high HRs, CMC was significantly superior to STD with respect to vessel sharpness of the RCA (p ConclusionsThe CMC improves image quality in CCTA, with particularly notable benefits for the RCA under high HR conditions.
