BACKGROUND Pulmonary zygomycosis (PZ), an emerging mycosis among patients with cancer, has a clinical manifestation similar to that of invasive pulmonary aspergillosis (IPA). Most cases of PZ in such patients develop as breakthrough infections if treatment with antifungal agents effective against Aspergillus species is administered. However, clinical(More)
PURPOSE To retrospectively establish normal values for pulmonary vein diameter, cross-sectional area, and shape depicted at computed tomography (CT). MATERIALS AND METHODS Institutional review board waived patient consent requirement and approved the study. Thin-section contrast material-enhanced spiral chest CT scans in 104 patients, 68 women and 36 men(More)
Detection of incidental malignant lesions in the breast has a significant clinical impact not only on healthy individuals but also on patients with known malignant disease. This review describes a spectrum of metastatic breast lesions incidentally detected by FDG PET-CT at staging that may be misinterpreted as second primary malignancy. The common(More)
BACKGROUND Integrated computed tomography-positron emission tomography imaging with coregistration of anatomic and functional imaging data may improve the accuracy of malignant pleural mesothelioma staging. We evaluate the use of integrated computed tomography-positron emission tomography in patients with malignant pleural mesothelioma who are being(More)
OBJECTIVE The purpose of this study was to report the prevalence of abnormalities that do not show increased 18F-FDG uptake on the CT component of integrated PET/CT in patients with non-small cell lung cancer. MATERIALS AND METHODS Images from all PET/CT studies performed consecutively between April and October 2003 on patients with non-small cell lung(More)
PURPOSE To evaluate and classify the various drainage patterns of the pulmonary veins as depicted with thin-section chest computed tomography (CT). MATERIALS AND METHODS Thin-section (2.5-mm collimation) contrast material-enhanced CT scans of 201 consecutive patients obtained over a 3-month period for diagnosis of pulmonary embolism (n = 197), pulmonary(More)
PURPOSE To determine the sensitivity of fluorodeoxyglucose (FDG) positron emission tomography (PET) in patients with T1 (< or =3 cm) lung cancers. MATERIALS AND METHODS One hundred eighty-five patients with 192 histopathologically proved T1 lung cancers underwent FDG PET imaging at the time of diagnosis. PET results were correlated with tumor size,(More)
Measuring tumor response to chemotherapy is important for both clinical decision-making and for multi-institutional studies. Thymoma tends to spread along the pleura: a challenge for accurate tumor measurement. Inaccurate and inconsistent tumor measurements often compromise results from clinical trials that are dependent on identifying response rate and(More)
OBJECTIVE A potential source of false-positive FDG PET interpretations in oncologic imaging is FDG uptake in brown fat. The purpose of this study was to determine the prevalence, location, and appearance of hypermetabolic brown fat in the mediastinum. MATERIALS AND METHODS All PET/CT scans obtained at our cancer institution from August to October 2003(More)
PURPOSE To determine whether contrast material-enhanced helical computed tomography (CT) of the thorax and upper abdomen changes the tumor stage and management compared with nonenhanced helical CT in patients with newly diagnosed lung cancer. MATERIALS AND METHODS During 15 months, any patient in whom lung cancer was strongly suspected or newly diagnosed(More)
