Patients without stones in ERCP were also negative in CT. The patient having the failed ERCP was considered positive in CT. The CT sensitivity was 80% and specificity was 100%, with an accuracy of 90%. Helical CT without contrast has sensitivity and specificity good enough to be used as a...
To compare the effectiveness of the bismuth breast shield and partial CT scan in reducing entrance skin dose and to evaluate the effect of the breast shield on image quality (IQ). Methods. Nanodots were placed on an adult anthropomorphic phantom. Standard chest CT, CT with shield, and partial...
腹部增强CT常用于检查肝脏、胆囊、胰腺、肾脏疾病[1-2]。对比剂可以显著提升增强CT的诊断效率,但可能引起一些不良反应[3]。碘克沙醇是一种等渗非离子型碘对比剂,近年来多用于增强CT中,与其他碘对比剂相比在保证图像质量的同时具有更好的安全性[4]。但目前碘克沙醇较多的研究集中于心脏冠状动脉CT,在腹部增强...

They have been shown to have a biodistribution throughout the lungs that allow an accurate assessment of regional lung perfusion and ventilation function. The principle of lung V/Q PET/CT imaging is to assess similar physiological processes than with conventional V/Q scan, but with greater ...
For CT scan image segmentation, we used a convolutional–deconvolutional capsule network, called SegCaps [25], and a CapsNet [26] with a combination of IELMs trained for improved generalization. While compared to the performance of other DL models, we found that the performance of CapsNet when ...
Member's most recent CAC scan was at least 5 years ago; and Discovery of coronary calcium would change management. Aetna considers calcium scoring by means of low-dose CT angiography medically necessary for persons who meet criteria for diagnostic cardiac CT angiography to assess whether an adequat...
