Woodworkers in the furniture industry are exposed to wood dust in their workplaces. The aim of this study is to investigate the effect of occupational wood dust exposure on the nasal mucociliary transport rates (NMTRs) in woodworkers. Twenty five woodworkers and 30 healthy controls were included in this study. Wood dust concentration in workplaces was measured using the sampling device. (99m) T...

Lovering AT, Haverkamp HC, Romer LM, Hokanson JS, Eldridge MW. Transpulmonary passage of Tc macroaggregated albumin in healthy humans at rest and during maximal exercise. J Appl Physiol 106: 1986–1992, 2009. First published April 16, 2009; doi:10.1152/japplphysiol.01357.2007.—We have demonstrated that 50m-diameter arteriovenous pathways exist in isolated, healthy human and baboon lungs, ventila...

BACKGROUND & AIMS Efficacy of radioembolization is derived from radioinduced damage, whereas tumour dosimetry is not considered as yet in prospective clinical trials. OBJECTIVES This study evaluates the impact of tumour dose (TD), based on 99m Tc macroaggregated albumin (MAA) quantification, on response and overall survival (OS). MATERIALS AND METHODS We consecutively included 85 patients w...

Fast biodegradable (12 h < half-life < 48 h) radioactive labeled microspheres are needed for PET and SPECT lung perfusion and radiomicrosphere therapy planning. An emulsion method was used to create 30.1 ±4.8  μ m size range microspheres with biodegradable Chitosan glycol (CHSg). Microspheres were characterized and labeled with (99m)Tc or (68)Ga as an alternative to MAA in perfusion PET and SPE...

PURPOSE To determine (a) whether superselective angioscintigraphy with technetium-99m macroaggregated albumin (99mTc-MAA) can be used for the evaluation of arteriovenous shunting in tumors and vascular malformations of the head and spine and (b) whether the amount of microparticles shunted is related to diagnosis, lesion size, or angiographic pattern. METHODS Particles of 99mTc-MAA with a cal...

Objectives. The aim of this study was to assess the effectiveness of SPECT/CT for volume measurements and to report a case illustrating the major impact of SPECT/CT in calculating the vascularized liver volume and dosimetry prior to injecting radiolabelled yttrium-90 microspheres (Therasphere). Materials and Methods. This was a phantom study, involving volume measurements carried out by two ope...

Peritoneal radionuclide scan is an established imaging modality for evaluating peritoneopleural communications. In this case report, unusual mediastinal lymph node radiotracer uptake is seen in a patient with portal hypertension on peritoneal scintigraphy. This was suspected to be due to marked lymphatic enlargement from longstanding portal hypertension since childhood, permitting passage of th...

Background: Treatment records and follow-up data on 40 patients with primary and metastatic liver malignancies who underwent a single whole-liver treatment with Y-90 resin microspheres (SIR-Spheres® Sirtex Medical, Lake Forest, IL) were retrospectively reviewed. The objective of the study was to evaluate the anatomic and physiologic determinants of radiation dose distribution, and the dose resp...
