Objective: The study aimed at evaluating the local tumor control, survival data and prognostic factors following treatment with transarterial chemoembolization (TACE) in the palliative therapy of patients with liver metastases from non-small-lung-cancer (NSCLC). Material and methods: The study was retrospectively performed following approval of the ethical committee. 56 patients (mean age, 53.4 years) with liver metastases of NSCLC (Stage IV) undergone repeated TACE. Overall, 214 TACE procedures were administered (mean, 3.8 sessions/patient). The administered chemotherapeutic agents included mitomycin, gemcitabine and cisplatin. For embolization lipiodol and degradable starch microspheres (DSM) were used.

Rosai-Dorfman disease (RDD), also referred to as sinus histiocytosis with massive lymphadenopathy (SHML), is a rareproliferative disorder of phagocytic histiocytes of unknown etiology. Systemic RDD most typically presents as painless cervical lymphadenopathy with constitutional symptoms. Extranodal involvement by RDD has been reported in nearly half of all cases, including skin, head/neck and upper respiratory tract.

A Retrospective Comparison of Pre-Operative Computed Tomographic Angiography (CTA) Performed at 100 versus 120 kVp Tube Energies and Surgical Findings at Laparoscopic Donor Nephrectomy
Pardeep Mittal, Courtney C Moreno, Jianhai Li, Kenneth Newell, William E Torres and William Small
Introduction: A retrospective review of patients who underwent preoperative Computed Tomographic Angiography (CTA) prior to living laparoscopic renal donation was performed. Image quality and accuracy were compared at 120 and 100 kVp tube energies with respect to quantitative image parameters and prediction of surgical findings. Material and methods: A total of 193 patients were reviewed, all of whom underwent laparoscopic donor nephrectomy with preceding CTA evaluation over a 5.5 year period.

The aim of this study was to evaluate radiation protection techniques in computed tomography (CT) scanning, address concerns on the increased population exposure during CT procedures, and provide a review on dose management and optimization procedures. Radiation protection in CT requires regular dose surveys and optimization of CT exposure parameters, establishing and/or implementing diagnostic references (DRLs), implementation of a comprehensive quality assurance program, reference dose levels, and CT dose saving protocols.

Objectives: Adult patients with intracranial hemorrhage (ICH) are often young but receive serial cranial computer tomography (CCT). To lower their cumulative radiation dose risks, we evaluated applicability of low dose cranial CT (LD-CCT) in the follow-up of ICH patients compared to an initial standard dose cranial CT (SD-CCT). Methods: 53 ICH patients underwent initial SD-CCT (350 mAs/120 kV) and follow-up LD-CCT (either 220 or 240 mAs/120 kV). Iterative reconstruction used for both dose levels was increased by one factor for LD-CCT. Image quality parameters [visual impression (VI), gray matter (GM)/white matter (WM) differentiation, edema, ICH, cerebrospinal fluid spaces (CSF), postoperative changes, basal cisterns] were retrospectively assessed independently by an experienced neuroradiologist and neurosurgeon. Significance level was set at p < 0.05.
