Objective
The present study aimed to characterize and differentiate the ultrasonography (US) and computed tomography (CT) features of mammary analogue secretory carcinoma (MASC) and acinic cell carcinoma (AciCC).
Methods and patients
A total of 83 patients with clinically proven MASC and AciCC were analyzed. The following characteristics were assessed on US, CT, and magnetic resonance imaging:...
To realize dose deformation and accumulation using image registration technology, and evaluate the anatomic changes and corresponding dosimetric variations for patients with nasopharyngeal carcinoma (NPC). 15 patients with NPC treated with IMRT were selected in this study, the original treatment plan(Plan1(CT1)) based on the first CT scan(CT1) and the second plan(Plan2(CT2)) based on the repeated...
The purpose of this study is to evaluate the dosimetric gain of the adaptive radiotherapy (ART) over conventional intensity modulated radiation therapy (IMRT) by using as the deformable image registration technique for dose mapping and summation to assess the dosimetric difference on target and organs at risk (OARs) dose. We retrospectively collected planning CT images and fractional CT images from...
