RETRACTED: 3D-Method for Determining the Imaging Quality of Ultrasound Probes
Abstract:
Monitoring ultrasonic probe quality remains an important problem which impacts diagnostic accuracy. Here we present a quantitative method to assess probe quality primarily based on measuring probe maximum contrast (dB) and dynamic range. Contrast relevant parameters of 26 transducer models manufactured by five manufacturers were measured with a novel Random Void Phantom (RVP) approach. 3D-data were acquired and analysed to determine image quality. Acoustic contrast values ranging from 15dB to 36dB were observed. By examining artefact producing side lobes, the novel RVP approach presented here per...
Lung Cancer and Isolated Adrenal Metastases: Different Disease?
Abstract:
Distant metastases generally indicate disseminated disease and the standard treatment for these patients is palliative chemotherapy. Retrospective series showed that selected patients with metastatic lung cancer and a solitary extrathoracic disease could be effectively treated with curative intention by resection of both primary tumor and the single site of metastatic disease. According to current data, adrenalectomy might be considered as an alternative option for patients with isolated adrenal metastases. Significant morbidity and mortality may be happened by these procedures, and a cautious analysis of pros and cons should be discussed with the patient. We present a review of the literature and updated recommendations focusing lung cancer with solitary adrenal metastasis.
