New CT rule-out examination cuts patient x-ray exposure
High radiation exposure has been the bogeyman keeping the cardiac CT triple rule-out exam for chest pain from widespread application.
High radiation exposure has been the bogeyman keeping the cardiac CT triple rule-out exam for chest pain from widespread application. The use of radiation dose reduction techniques addresses that concern.
Dr. Kevin Takakuwa and colleagues at Thomas Jefferson University reviewed data from 267 consecutive patients who underwent triple rule-out cardiac CT angiography after presenting to the emergency roon with symptoms of acute coronary syndrome. Ninety-five patients underwent the triple rule-out CTA protocol with tube current modulation, and 172 did so without it. Investigators found that patients undergoing triple rule-out without tube current modulation received average effective radiation doses of 18 mSv. Those getting the exam with tube current modulation, however, had effective radiation doses reduced by more than 50% without image quality loss. Findings were published in the American Journal of Roentgenology (2009;192[4]:866-872).
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
