The role of fusion positron emission tomography/computed tomography scans (PET/CT) in staging of patients with pancreatic neoplasms (PN) is poorly defined. PET/CT may serve as an adjunct to standard imaging by increasing occult metastases detection. The purpose of this study was to assess the additional value, in relation to computed tomography (CT), of(More)
A procedure was devised to quickly and reliably determine the patency of the cystic duct in patients suspected of having acute cholecystitis. First the gallbladder was stimulated to empty by a cholecystokinin injection. Thirty minutes later a radiolabeled biliary marker, either 150 muCi 131-I rose bengal or 2 mCi 99-mTc dihydrothioctic acid, was injected,(More)
Two CT features were developed to quantitatively describe lung adenocarcinomas by scoring tumor shape complexity (feature 1: convexity) and intratumor density variation (feature 2: entropy ratio) in routinely obtained diagnostic CT scans. The developed quantitative features were analyzed in two independent cohorts (cohort 1: n = 61; cohort 2: n = 47) of(More)
PURPOSE Tumor response is considered a surrogate marker of survival. We investigated whether tumor response based on computed tomography (CT) scan or whole-body [(18)F]fluorodeoxyglucose positron emission tomography (PET) scan after neoadjuvant chemotherapy for resectable non-small-cell lung cancer (NSCLC) is prognostic of survival.

UNLABELLED In this study we developed 25 computed tomography descriptors among 117 patients with lung adenocarcinoma to semiquantitatively assess their association with overall survival. Pleural attachment was significantly associated with an increased risk of death and texture was most important for distinguishing histological subtypes. This approach has(More)
OBJECTIVE/BACKGROUND There is a high risk of relapse in stage IIIB/IIIC melanoma. The utility of 2-[fluorine-18]-fluoro-2-deoxy-D-glucose positron emission tomography integrated with computed tomography (FDG-PET/CT) in these patients to evaluate response to treatment or for surveillance after treatment is currently not well defined. METHODS Prospective(More)
In a randomized, double-blind trial, 5,000 USP units of sodium heparin or saline were give subcutaneously at least two hours before surgery and at 12 hour intervals thereafter to patients requiring total hip replacement, surgical correction of hip fracture, or major lower extremity amputation for vascular insufficiency. Lung perfusion scans were performed(More)
PURPOSE To correlate prospective imaging findings in patients with intractable partial epilepsy with site of surgery and clinical outcome. MATERIALS AND METHODS Thirty-five patients (25 male, 10 female) underwent positron emission tomography (PET; n=25), interictal single photon emission computed tomography (SPECT; n=33), or postictal SPECT (n=23) for(More)
PURPOSE To compare the ability of qualitative fludeoxyglucose F 18 positron emission tomography (QPET), qualitative MR imaging (QMR), and quantitative MR imaging with hippocampal formation volumetric assessment (HV MR) to lateralize the seizure focus in patients with temporal lobe epilepsy. METHODS Sixteen consecutive patients undergoing presurgical(More)
