Regional breath sound distribution analysis in single-lung transplant recipients.

Background: Perfusion scintigraphy has been used to evaluate and monitor graft function in single-lung transplant recipients. In this study, our objective was to determine whether quantitatively measured regional breath sounds, using a computerized breath sound analysis device, correlate with the standard methods of monitoring graft function used at our facility for single-lung transplant patients.

Methods: Quantitative regional breath sound measurements (QLD VRI) were performed with a VRIxp device on 37 single-lung transplant patients, who underwent perfusion scans and lung function testing for routine follow-up.

Quantitative lung perfusion following single lung transplantation.

Background: Following successful lung transplantation, most of the lung perfusion, as well as ventilation, is shifted towards the transplanted lung. We investigated the changes in perfusion during exercise in lung transplant recipients.

Patients And Methods: Twelve patients were included in the study.

Short- and long-term outcome of lung volume reduction surgery. The predictive value of the preoperative clinical status and lung scintigraphy.

The NETT study assessed the benefits of lung volume reduction surgery (LVRS) versus medical treatment. However, data is available only on the early outcome of LVRS (24 months). We evaluate the factors affecting the outcome at one-year and up to 6 years after LVRS.

Lymphatic drainage to the popliteal basin in distal lower extremity malignant melanoma.

Unlabelled: Hypotheses Melanoma of the distal lower extremity may drain to the popliteal basin. Drainage pathways and retrieval of the popliteal sentinel nodes may affect patient outcome.

Design: Retrospective analysis of popliteal involvement in patients with stage IB or higher melanoma, operated on from August 1, 1993, to July 31, 2003.

PET-CT fusion imaging in differentiating physiologic from pathologic FDG uptake.

Interpretation of positron emission tomographic (PET) scans in the absence of correlative anatomic information can be challenging. PET-computed tomography (CT) fusion imaging is a novel multimodality technology that allows the correlation of findings from two concurrent imaging modalities in a comprehensive examination. CT demonstrates exquisite anatomic detail but does not provide functional information, whereas 2-[fluorine 18]fluoro-2-deoxy-D-glucose (FDG) PET reveals aspects of tumor function and allows metabolic measurements.
