This consensus statement from the members of the American Neurogastroenterology and Motility Society and the Society of Nuclear Medicine recommends a standardized method for measuring gastric emptying (GE) by scintigraphy. A low-fat, egg-white meal with imaging at 0, 1, 2, and 4 h after meal ingestion, as described by a published multicenter protocol,(More)
Three patients developed supraumbilical skin rashes during hepatic artery infusion chemotherapy by a surgically placed perfusion catheter and drug-infusion pump. In one patient, hepatic arterial scintigraphy with technetium-99m macroaggregated serum albumin showed increased uptake corresponding to the rash, and a hepatic arteriogram showed a dilated(More)
BACKGROUND AND AIMS Cholecystokinin-cholescintigraphy (CCK-CS) provides a physiologic, noninvasive, and quantitative method for assessing gallbladder contraction and calculation of a gallbladder ejection fraction (GBEF). At present, it is used most commonly to identify patients with suspected functional gallbladder disorder. However, the methodology of CCK(More)
This study examines the frequency and significance of diffuse liver uptake on 131I whole-body thyroid cancer scans. Sixty whole-body scans on 27 patients with differentiated thyroid cancer were reviewed. Liver uptake was quantitated on another 21 studies (16 patients). Diffuse hepatic uptake was seen in 44% of patients and 35% of all the studies. It(More)
PURPOSE To evaluate the safety, tolerability, and pharmacokinetics of biricodar (VX-710), an inhibitor of P-glycoprotein (P-gp) and multidrug resistance-associated protein (MRP1), alone and with doxorubicin in patients with advanced malignancies. The effect of VX-710 on the tissue distribution of (99m)Tc-sestamibi, a P-gp and MRP1 substrate, was also(More)
Radionuclide studies of gastric emptying and motility are the most comprehensive and physiologic studies of gastric motor function available. The studies are noninvasive, use a physiologic meal (solids with or without liquids), and are quantitative. Serial testing can determine the effectiveness of therapy. The Society of Nuclear Medicine (SNM) and the(More)
PURPOSE To establish normal gallbladder ejection fraction (GBEF) values for two sincalide (cholecystokinin [CCK]) infusion dose rates, 0.01 microg per kilogram of body weight infused for 3 minutes and 0.01 microg/kg infused for 60 minutes. MATERIALS AND METHODS Twenty healthy subjects were examined. GBEFs were calculated for the 3-minute infusion and for(More)
IMPORTANCE Existing data regarding the association between delayed initiation of antimicrobial therapy and the development of renal scarring are inconsistent. OBJECTIVE To determine whether delay in the initiation of antimicrobial therapy for febrile urinary tract infections (UTIs) is associated with the occurrence and severity of renal scarring. (More)
OBJECTIVE Although the prevalence of intracranial lymphoma is high among patients with AIDS, current imaging techniques are not reliable for differentiating this tumor from other common nonneoplastic lesions, such as those seen in toxoplasmosis. The purpose of this study was to prospectively investigate the use of 201Tl single-photon emission computed(More)
Tc-99m-MAA hepatic arterial perfusion scintigraphy ( HAPS ) using a totally implanted drug delivery system was employed for hepatic arterial chemotherapy in 147 patients (335 studies). Complete perfusion of the involved liver was seen in 88% of patients initially [more so in those with normal hepatic vascular anatomy (93%) than those with vascular variants(More)
