OBJECTIVE To assess the effectiveness of bronchial artery embolization (BAE) in patients with malignant hemoptysis. METHODS An IRB-approved retrospective study at our academic institution was conducted on all patients treated by BAE for hemoptysis from lung malignancy. Outcome and safety measures were documented according to Society of Interventional(More)
This article educates the reader on idiopathic retroperitoneal fibrosis and emphasizes the importance of considering conditions that mimic this disease on PET/CT through an illustrative case of a 58 year-old man presenting with intermittent abdominal, back, and scrotal pain undergoing successive PET/CT scans, both for diagnosis and following treatment.
There are several artifacts encountered in positron emission tomography/computed tomographic (PET/CT) imaging, including attenuation correction (AC) artifacts associated with using CT for AC. Several artifacts can mimic a 2-deoxy-2-[18F] fluoro-d-glucose (FDG) avid malignant lesions and therefore recognition of these artifacts is clinically relevant. Our(More)
Vestibular influences on outflow from the spinal cord are largely mediated via spinal interneurons, although few studies have recorded interneuronal activity during labyrinthine stimulation. The present study determined the responses of upper thoracic interneurons of decerebrate cats to electrical stimulation of the vestibular nerve or natural stimulation(More)
There are several artifacts unique to PET/CT imaging, with CT-based attenuation correction (AC) artifacts being among the most commonly reported. AC artifacts from calcified lymph nodes represent clinically significant and easily misinterpreted PET/CT artifacts that have received little attention in the literature. In this case series, we report three cases(More)
Biofilms are etiologically important in the development of chronic medical and dental infections. The biofilm extracellular polymeric substance (EPS) determines biofilm structure and allows bacteria in biofilms to adapt to changes in mechanical loads such as fluid shear. However, EPS components are difficult to visualize microscopically because of their low(More)
PURPOSE To compare measures of clinical success, such as the need for subsequent intervention and mortality, in patients with left ventricular assist devices (LVADs) undergoing mesenteric angiography for gastrointestinal (GI) bleeding with respect to a control group. MATERIALS AND METHODS A retrospective study was conducted on 48 consecutive patients(More)
Giant encephalocele is an uncommon congenital anomaly with very few published reports available in the English literature. Tetralogy of Fallot associated with situs inversus is also infrequently reported. To our knowledge there are no published reports of an association between giant encephalocele and Tetralogy of Fallot. The additional finding of situs(More)
