Simulation-based education in ultrasound - diagnostic and interventional abdominal focus.

Simulation-based training (SBT) is increasingly acknowledged worldwide and has become a popular tool for ultrasound education. Ultrasound simulation involves the use of technology and software to create a virtual training setting. Simulation-based training allows healthcare professionals to learn, practice, and improve their ultrasound imaging skills in a safe learning-based environment.

Four Virtual-Reality Simulators for Diagnostic Abdominal Ultrasound Training in Radiology.

Ultrasound exams need skilled examiners, and simulation-based training could provide standardized and safe skill training. This study aims to give an overview of different types of virtual-reality simulators for use in abdominal diagnostic ultrasound training in radiology. Fifteen specialized radiologists and radiological residents were presented with two similar cases on four different simulators for abdominal ultrasound training.

Simulator training improves ultrasound scanning performance on patients: a randomized controlled trial.

Background: Simulation-based mastery training may improve clinical performance. The aim of this study was to determine the effect of simulation-based mastery training on clinical performance in abdominal diagnostic ultrasound for radiology residents.

Method: This study was a multicenter randomized controlled trial registered at clinicaltrials.

Determining procedures for simulation-based training in radiology: a nationwide needs assessment.

Objectives: New training modalities such as simulation are widely accepted in radiology; however, development of effective simulation-based training programs is challenging. They are often unstructured and based on convenience or coincidence. The study objective was to perform a nationwide needs assessment to identify and prioritize technical procedures that should be included in a simulation-based curriculum.

[Gastric bezoar caused by barium sulphate].

We present the first case of a gastric bezoar caused by barium sulphate acting as an intermittently occluding mass in a patient who had undergone small bowel follow-through on suspicion of small bowel obstruction (SBO) after total pancreatectomy. The patient underwent acute surgery but intermittent symptoms of SBO persisted. A barium bezoar was seen on plain abdominal film and afterwards diluted and fragmented gastroscopically.

The diagnostic value of adding dynamic scintigraphy to standard delayed planar imaging for sentinel node identification in melanoma patients.

Purpose: The aim of this study was to compare early dynamic imaging combined with delayed static imaging and single photon emission computed tomography (SPECT)/CT with delayed, planar, static imaging alone for sentinel node (SN) identification in melanoma patients.

Methods: Three hundred and seven consecutive melanoma patients referred for SN biopsy (SNB) were examined using combined imaging. Secondary interpretation of only the delayed static images was subsequently performed.

Studies on radionuclide imaging and contrast ultrasound for sentinel node diagnostics in breast cancer and melanoma.

Unlabelled: Malignant involvement of the regional lymph nodes in breast cancer, melanoma and other cancers is considered an important prognostic factor and determines the further treatment of the patient. Currently two methods are most often combined for SN detection, intra-operative blue dye injection around the tumour site and the radionuclide technique. The aims of this thesis were to evaluate the possibility of optimising the radionuclide SN procedures in patients with breast cancer and melanoma, and to examine the possibility of using contrast enhanced lympho-ultrasonography (CELUS) for SN detection.

Biopsy guided by real-time sonography fused with MRI: a phantom study.

Objective: The purpose of our study was to test the accuracy of sonographically guided biopsies in a phantom of structures not visible on sonography but shown on MRI by using commercially available sonography systems with image fusion software.

Materials And Methods: A previously recorded MRI examination from a custom-made phantom was loaded into the sonography system. The phantom contained spheres that were invisible to sonography and contained red dye.

Examples of in vivo blood vector velocity estimation.

In this paper, a case study of in-vivo blood vector velocity images of the carotid artery are presented. The transverse oscillation (TO) method for blood vector velocity estimation has been used to estimate the vector velocities. The carotid arteries of three healthy volunteers are scanned in-vivo at three different positions by experienced sonographers.
