Radiation dose reduction of 50% in dynamic myocardial CT perfusion with skipped beat acquisition: a retrospective study
CONCLUSION: Skipping every second beat acquisition during dynamic myocardial CTP appears feasible and may result in a radiation dose reduction of 50%. Diagnostic performance does not decrease after removing 50% of time points in dynamic sequence.PMID:38630492 | DOI:10.1177/02841851241240446 (Source: Acta Radiologica)

The value of CT radiomics combined with deep transfer learning in predicting the nature of gallbladder polypoid lesions
CONCLUSION: The machine learning radiomics combined with deep learning model based on enhanced CT proves valuable in predicting the characteristics of cholesterol and adenomatous gallbladder polyps. This approach provides a more reliable basis for preoperative diagnosis and treatment of these conditions.PMID:38623640 | DOI:10.1177/02841851241245970 (Source: Acta Radiologica)

Clinical feasibility of post-contrast accelerated 3D T1-Sampling Perfection with Application-optimized Contrasts using different flip angle Evolutions (SPACE) with iterative denoising for intracranial enhancing lesions: a retrospective study
CONCLUSION: Although accelerated T1-SPACE markedly decreased the scan time, it showed lower overall image quality and lesion detectability than the standard T1-SPACE. Application of ID to accelerated T1-SPACE resulted in comparable overall image quality and detection of enhancing lesions in brain parenchyma as standard T1-SPACE. Accelerated T1-SPACE with ID may be a promising replacement for standard T1-SPACE.PMID:38623647 | DOI:10.1177/02841851241245104 (Source: Acta Radiologica)

Prominent crista terminalis mimicking a right atrial mass: a systematic literature review and meta-analysis
We describe up to date and detailed imaging features for the differential diagnostics of selected intracardiac masses using various imaging techniques, including multimodality cardiac imaging. Familiarity with the anatomy and the imaging findings of the prominent crista terminalis will reduce misdiagnosis and avoid additional tests and unwarranted clinical interventions, while in patients considered for invasive cardiac procedures it might increase their efficacy and safety.PMID:38619912 | DOI:10.1177/02841851241242461 (Source: Acta Radiologica)

Comparison of MRI findings of hypothalamic-optic chiasmatic gliomas and craniopharyngiomas
CONCLUSION: Although some neuroimaging findings may overlap, features such as presence of cyst and calcification, brain stem and optic pathway involvement, different enhancement patterns, and ADC values may be helpful in the differential diagnosis of HOCGs and craniopharyngiomas.PMID:38613353 | DOI:10.1177/02841851241241527 (Source: Acta Radiologica)

Does volumetric measurement of ADC values achieve higher diagnostic performance in bladder cancer MRI?
CONCLUSION: The selected ROI and volumetric measurement methods of mean and minimum ADC in bladder cancer yield different values, still having comparable diagnostic performance with accurate ROI sampling. The minimum ADC value by ROI is preferred in everyday clinical practice.PMID:38591942 | DOI:10.1177/02841851241241055 (Source: Acta Radiologica)
