CT-guided percutaneous ablation for liver cancer treatment is a relevant technique for patients not eligible for surgery and with tumors that are inconspicuous on US imaging. The lack of real-time imaging and the use of a limited amount of CT contrast agent make targeting the tumor with the needle challenging. In this study, we evaluate a registration framework that allows the integration of di...

Visual field deficits due to optic radiation injury are a common complication of temporal lobectomy in epilepsy surgery. In this prospective study, diffusion tensor imaging (DTI) based fiber tracking was performed on 48 patients who had temporal lobectomy for pharmaco-resistant epilepsy. Pre- and intra-operative DTI based fiber tracking was used to visualize the optic radiation and to predict t...

AIM To show our experience using the portable gamma camera during surgery in the detection of the sentinel node in breast cancer. MATERIAL AND METHODS A total of 46 women diagnosed with breast cancer were included. This study was carried out by means of the periareolar intradermal injection. Planar images and SPECT/CT were acquired. On the following day, the sentinel nodes were localized intr...

Introduction: Tonsillectomy is a painful surgical procedure accompanied by moderate to severe pain several days after surgery. Despite the often tonsillectomy, under-treatment of has been consistently reported. The cause this inadequate education health care professionals regarding management. Objectives: aim study was assess perioperative treatment given tonsillectomy patients in otorhinolaryn...

Modeling of the tomographic weights usually incorporates angle of view, decay and attenuation. A usual assumption is that the gamma camera is a long way from the object, this leads to the approximation that the angle of view subtending the front of the collimator tube is the same as that subtending the back (Weir & Green, 1994). However, if the distance between camera and subject is small then ...

PURPOSE To compare patients with or without intra-operative fracture during cementless bipolar hemiarthroplasty. METHODS Records of 76 men and 202 women who underwent cementless bipolar hemiarthroplasty for femoral neck fractures were reviewed. Patients with and without intra-operative fractures and patients with different types of intra-operative fractures were compared. RESULTS Two men an...

The aim of this study was to ascertain the incidence of "increased endometrial vascularity" recorded in the ultrasound scan reports, in the context of RPOC and correlate this finding with the incidence of life threatening intra-operative bleeding. Ultrasound scan reports sometimes mention the presence of increased endometrial / sub-endometrial vascularity in the context of retained products of ...

PURPOSE To establish the feasibility of single-surgeon laparoscopy with application of a novel endoscope-holder device and to compare this technique with traditional assistant-driven laparoscopic camera control. MATERIALS AND METHODS Bilateral simple nephrectomies were performed in six pigs. On one side, the operating surgeon employed the "scope holder" and performed the surgery without a lap...
