Objective To examine the effects of positive end-expiratory pressure (PEEP) on extravascular lung water (EVLW), lung tissue, and lung volume. Design and setting Experimental animal study at a university research facility. Subjects Fifteen... more
Aim  Automatic CT dataset classification is important to efficiently create reliable database annotations, especially when large collections of scans must be analyzed. Method  An automated segmentation and labeling algorithm was developed... more
Subarachnoid hemorrhage (SAH) is a medical emergency which can lead to death or severe disability. Misinterpretation of computed tomography (CT) in patients with SAH is a common problem. How to improve the accuracy of diagnosis is a great... more
We propose a new hierarchical approach to resolution scalable lossless and near-lossless (NLS) compression. It combines the adaptability of DPCM schemes with new hierarchical oriented predictors to provide resolution scalability with... more
To study the impact of fused (18)F-fluoro-deoxy-D-glucose (FDG)-hybrid positron emission tomography (PET) and computed tomography (CT) images on conformal radiation therapy (CRT) planning for patients with esophageal carcinoma.... more

Biopsy of the musculoskeletal system is useful in the management of bone lesions particularly in oncology but they are often challenging procedures with a significant risk of complications. Computed tomography (CT)-guided needle biopsies... more
Neuroimaging plays a major role in the evaluation of patients with neurologic disorders. The utility of various neuroimaging studies is rapidly increasing in both clinical and research settings. Neurologists should learn about the... more
Congenital nasolacrimal duct mucocele (CNDM) is a very rare condition in newborns. Prolapse or expansion of the mucocele into the nose may lead to respiratory distress and difficulty in feeding. The triad of cystic medial canthal mass,... more
We studied the role of duplex Doppler ultrasonography in the diagnosis of renal obstruction caused by ureteral calculi. Using duplex Doppler sonography, we evaluated the intrarenal hemodynamics of 27 patients who presented to the... more
A method for automatic segmentation of pulmonary lobes from computed tomography (CT) scans is presented that is robust against incomplete fissures. The method is based on a multiatlas approach in which existing lobar segmentations are... more
