Diagnostic value of qualitative and quantitative enhancement parameters on contrast-enhanced mammography
CONCLUSION: Diagnostic accuracy of quantitative parameters was higher than that of qualitative parameters. High CNR, rim enhancement, and descending pattern were features commonly seen in malignant lesions, while low CNR, homogeneous enhancement, and ascending pattern were commonly seen in benign lesions.PMID:38619006 | DOI:10.4274/dir.2024.232472 (Source: Diagnostic and Interventional Radiology : The Turkish Society of Radiology)

Post-contrast abdominal magnetic resonance imaging of critically ill patients using compressed sensing free-breathing golden radial angle imaging
Diagn Interv Radiol. 2024 Apr 5. doi: 10.4274/dir.2024.232646. Online ahead of print.ABSTRACTObtaining diagnostic-quality magnetic resonance imaging (MRI) of the abdomen in critically ill patients can be difficult due to challenges with breath-holding and the inability to follow technologist instructions. Protocols that harness advances in commercially available MRI techniques provide a potential solution, particularly using the golden radial angle sparse parallel (GRASP) technique for dynamic post-contrast T1-weighted imaging. The GRASP technique uses a combination of free-breathing, a stack-of-stars radial acquisition, a...

Value of perfusion parameters from golden-angle radial sparse parallel dynamic contrast-enhanced magnetic resonance imaging in predicting pathological complete response after neoadjuvant chemoradiotherapy for locally advanced rectal cancer
CONCLUSION: The use of a combination of the GRASP DCE-MRI Ktrans with mrTRG and ADC can lead to a better pCR predictive performance.PMID:38528760 | DOI:10.4274/dir.2024.232460 (Source: Diagnostic and Interventional Radiology : The Turkish Society of Radiology)
