PURPOSE We investigated the risk factors and management of pleural effusion associated with dasatinib therapy for chronic myelogenous leukemia (CML) after failure of imatinib. PATIENTS AND METHODS We analyzed 138 patients with CML treated with dasatinib from November 2003 to January 2006 in one phase I (n = 50) and four phase II (n = 88) studies for the(More)
PURPOSE To retrospectively evaluate bronchial and nonbronchial systemic arteries at multi-detector row helical computed tomography (CT) compared with conventional angiography in patients undergoing endovascular treatment of hemoptysis. MATERIALS AND METHODS Neither institutional board approval nor informed consent was required. Forty-eight consecutive(More)
Hemoptysis is symptomatic of a potentially life-threatening condition and warrants urgent and comprehensive evaluation of the lung parenchyma, airways, and thoracic vasculature. Multi-detector row computed tomographic (CT) angiography is a very useful noninvasive imaging modality for initial assessment of hemoptysis. The combined use of thin-section axial(More)
BACKGROUND The objective of the study was to determine the utility of integrated computed tomography / positron emission tomography (CT-PET) imaging for detecting interval distant metastases and assessing therapeutic response in patients with locally advanced, potentially resectable esophageal carcinoma after neoadjuvant therapy. METHODS A retrospective(More)
PURPOSE To prospectively evaluate gadolinium dose safety and effectiveness for 16-detector pulmonary computed tomographic (CT) angiography. MATERIALS AND METHODS Ethics committee approval and informed consent were obtained. Sixty patients with contraindications to iodine underwent CT of the pulmonary circulation with 0.5 mmol/L gadolinium chelate given at(More)
PURPOSE To retrospectively evaluate the sensitivity and specificity of contrast material-enhanced magnetic resonance (MR) angiography by using digital subtraction angiography as the reference standard in patients with hypertension and renal artery fibromuscular dysplasia (FMD). MATERIALS AND METHODS Institutional review board approval was obtained, with(More)
Gastrointestinal complications of chemotherapy may be serious and potentially life-threatening. Familiarity with and awareness of the potential complications associated with various chemotherapeutic agents/regimens is paramount to enable accurate and timely diagnosis. In this article we review the radiological manifestations of the most notable(More)
OBJECTIVE MDCT systems with fast scanning capabilities can acquire images of the thorax with reduced cardiac motion artifacts, enabling improved evaluation of the heart and surrounding structures in the course of routine thoracic CT. This article describes the principles of including an evaluation of the heart in the course of a chest CT examination in(More)
With increasing emphasis among the medical community on the early diagnosis and staging of colorectal cancer, interest has grown in CT colonography as a developing technique to challenge existing methods such as the barium enema and conventional colonoscopy. First introduced in 1994, CT colonography has experienced dramatic improvements in both hardware and(More)
Positron emission tomography (PET)/computed tomography (CT) has important utility and limitations in the initial staging of esophageal cancer, evaluation of response to neoadjuvant therapy, and detection of recurrent malignancy. Esophageal cancer is often treated by using a combined modality approach (chemotherapy, radiation therapy, and esophagectomy);(More)
