Rim Enhancement after Technically Successful Transarterial Chemoembolization in Hepatocellular Carcinoma: A Potential Mimic of Incomplete Embolization or Reactive Hyperemia?
Autor: Kaspar Ekert, Christopher Kloth, Konstantin Nikolaou, Gerd Grözinger, Marius Horger, Wolfgang Thaiss
Publikováno v: Tomography, Vol 8, Iss 2, Pp 1148-1158 (2022)
Contrast enhancement at the margins/rim of embolization areas in hepatocellular-carcinoma (HCC) lesions treated with transarterial chemoembolization (TACE) might be an early prognostic indicator for HCC recurrence. The aim of this study was to evalua

Autor: Patricia Sandqvist, Jacob Farnebo, Inga-Lena Nilsson, Per Grybäck, Anders Sundin, Alejandro Sanchez-Crespo
Publikováno v: Insights into Imaging, Vol 12, Iss 1, Pp 1-9 (2021)
Abstract Objectives To investigate the incremental value of Sestamibi SPECT combined with a non-enhanced and contrast-enhanced CT, using SPECT/CT, for the preoperative localisation of small parathyroid adenomas (PTA). Methods Retrospectively, 147 pat

Evaluation of Reconstruction Accuracy of 4-D CT Images for Real-Time Position ManagementTM System
Autor: Sumalee Yabsantia
Publikováno v: Journal of Health Science and Medical Research (JHSMR), Vol 33, Iss 2, Pp 93-101 (2015)
Moving target volume is a significant problem for cancer treatment. Four-dimensional computed tomography was developed to improve the treatment of this target volume. In the present, respiratory signal are combined with computed tomography images to

Optimization of a protocol for contrast-enhanced four-dimensional computed tomography imaging of thoracic tumors using minimal contrast agent
Autor: Yibing Zhou, Ding-Qiang Yang, Guanghui Li, Jian-Guo Sun, Hongya Dai, Lu Chen, Xiaojing Wen
Publikováno v: Strahlentherapie Und Onkologie
Purpose The accuracy of target delineation for node-positive thoracic tumors is dependent on both four-dimensional computed tomography (4D-CT) and contrast-enhanced three-dimensional (3D)-CT images; these scans enable the motion visualization of tumo
