Cone beam CT guidance provides superior accuracy for complex needle paths compared with CT guidance 23 Aug 2013 | 10:00 pm
Objective: To determine the accuracy of cone beam CT (CBCT) guidance and CT guidance in reaching small targets in relation to needle path complexity in a phantom. Methods: CBCT guidance combines th...
Venous compression syndromes: clinical features, imaging findings and management 23 Aug 2013 | 10:00 pm
Extrinsic venous compression is caused by compression of the veins in tight anatomic spaces by adjacent structures, and is seen in a number of locations. Venous compression syndromes, including Paget–...
Biphasic and monophasic repair: comparative implications for biologically equivalent dose calculations in pulsed dose rate brachytherapy of cervical c... 21 Aug 2013 | 02:09 pm
Objective: To consider the implications of the use of biphasic rather than monophasic repair in calculations of biologically-equivalent doses for pulsed-dose-rate brachytherapy of cervix carcinoma. ...
Justification of CT examinations in young adults and children can be improved by education, guideline implementation and increased MRI capacity 20 Aug 2013 | 07:37 pm
Objective: To determine whether the justification of CT examinations performed on young patients can be improved by various interventions and whether these have an effect on the total number of CTs p...
Stereotactic ablative radiotherapy in the UK: current status and developments 20 Aug 2013 | 07:37 pm
Stereotactic ablative radiotherapy (SABR) has developed from the principles and techniques used in the stereotactic radiosurgery treatment of brain metastases. Advances in computer technology, imaging...
K-edge ratio method for identification of multiple nanoparticulate contrast agents by spectral CT imaging 20 Aug 2013 | 07:37 pm
Objective: Recently introduced energy-sensitive X-ray CT makes it feasible to discriminate different nanoparticulate contrast materials. The purpose of this work is to present a K-edge ratio method f...
Planning comparison between standard and conformal 3D techniques in post-operative radiotherapy of gastric cancer: a systematic review 20 Aug 2013 | 07:37 pm
The objective of this study was to establish the impact of three-dimensional conformal radiotherapy (3D-CRT) technique in post-operative radiotherapy of gastric cancer. A bibliographical research was ...
Inter- and intrascanner variability of pulmonary nodule volumetry on low-dose 64-row CT: an anthropomorphic phantom study 20 Aug 2013 | 07:37 pm
Objective: To assess inter- and intrascanner variability in volumetry of solid pulmonary nodules in an anthropomorphic thoracic phantom using low-dose CT. Methods: Five spherical solid artificial n...
Iodine quantification with dual-energy CT: phantom study and preliminary experience with VX2 residual tumour in rabbits after radiofrequency ablation 20 Aug 2013 | 07:37 pm
Objective: The purpose of our study was to validate iodine quantification in a phantom study with dual-source dual-energy CT (DECT) and to apply this technique to differentiate benign periablational ...
Whole-tumour CT-perfusion of unresectable lung cancer for the monitoring of anti-angiogenetic chemotherapy effects 20 Aug 2013 | 07:37 pm
Objective: To determine whether CT-perfusion (CT-p) can be used to evaluate the effects of chemotherapy and anti-angiogenic treatment in patients with non-small-cell lung carcinoma (NSCLC) and whethe...
