Lateral approach for radiocarpal wrist arthrography.

Objective: We describe a technique of radiocarpal arthrography using the lateral approach. This technique may be used as an alternative to conventional dorsal techniques.

Conclusion: Radiocarpal injection using the lateral approach can be considered as an alternative to conventional dorsal approaches in the evaluation of wrist pain and instability.

In vivo validation of 3'deoxy-3'-[(18)F]fluorothymidine ([(18)F]FLT) as a proliferation imaging tracer in humans: correlation of [(18)F]FLT uptake by positron emission tomography with Ki-67 immunohistochemistry and flow cytometry in human lung tumors.

Purpose: Tumor proliferation has prognostic value in resected early stage non-small cell lung cancer (NSCLC) and can, therefore, predict which NSCLCs are at high risk for recurrence after resection and would benefit from additional therapy. It may also predict which tumor will respond to cell cycle-targeted chemotherapy and help assess the tumor response, besides helping to differentiate benign from malignant lung lesions. We evaluated whether the uptake of the new positron emission tomography (PET) tracer 3'deoxy-3'-[18F]fluorothymidine (FLT) in a series of suspected NSCLCs correlated with tumor proliferation assessed by Ki-67 immunohistochemistry and flow cytometry.

The impact of fluorodeoxyglucose F 18 positron-emission tomography on the surgical staging of non-small cell lung cancer.

Objectives: Staging data on patients with non-small cell lung cancer were prospectively collected to evaluate the accuracy and anatomic information provided by fluorodeoxyglucose F 18 positron-emission tomography and its impact on improving the accuracy of surgical staging.

Methods: A total of 142 patients with potentially resectable non-small cell lung cancer were imaged with positron-emission tomography (neck to pelvis). Positron-emission tomographic scans were read prospectively with thoracic computed tomographic comparison.

The Ki-67 index and survival in non-small cell lung cancer: a review and relevance to positron emission tomography.

Purpose: We reviewed the current literature to discover the range of studies covering tissue-based and noninvasive methods for determining tumor stage and the prognostic value of staging in non-small cell lung cancer.

Design: Despite refinements in staging of non-small cell lung cancer, each stage remains heterogeneous because each stage contains patients who are at higher risk for recurrence than other patients within the same stage. Tissue-based and noninvasive methods have been investigated to complement tumor stage in assessing non-small cell lung cancer prognosis.
