Atraumatic CBF Measurement With the Scintillation Camera
A scintillation camera connected to a dedicated computer system was employed for atraumatic CBF measurements in 43 patients after intravenous injection of 35 to 55 raCi Xe in saline solution. To validate this method results were compared to flow values in the same patients measured after intracarotid Xe injection. While the correlation between i.e. and i.v. values was not satisfactory when a hi...
متن کاملMeasurement of iodine-123 thyroid uptake using a gamma camera with LEAP collimator.
OBJECTIVE This study compared the 123I thyroid uptake measurements obtained from a gamma camera fitted with a low-energy all-purpose (LEAP) collimator to those obtained from a thyroid uptake probe and gamma camera fitted with a pinhole (PH) collimator. METHODS Thirty-one patients (27 female and 4 male patients) were studied for comparison between a probe and a gamma camera fitted with LEAP co...
متن کاملNeuroblastoma imaging using a combined CT scanner-scintillation camera and 131I-MIBG.
UNLABELLED High-dose administration of 131I-metaiodobenzylguanidine (131I-MIBG) continues to be a promising treatment for neuroblastoma. However, currently used methods of estimating 131I-MIBG uptake in vivo may be too inaccurate to properly monitor patient radiation exposure doses. To improve localization and uptake measurements over currently practiced techniques, we evaluated different metho...
متن کاملMeasurement of regional myocardial perfusion in man with 133 xenon and a scintillation camera.
A method was devised to quantitate regional capillary perfusion in the human heart by measuring the clearance constants (k) of Xenon-133 washout from multiple areas of the myocardium with a multiple-crystal scintillation camera. In 17 subjects, (133)Xe was injected into the right or left coronary artery or both and counts per second (cps) were recorded simultaneously on magnetic tape from each ...
متن کاملMultiple non-malignant iodine uptake in a 131I whole body scan of a patient with papillary thyroid carcinoma: Importance of SPECT/CT
After thyroidectomy in papillary thyroid carcinoma (PTC) patients, whole body radioiodine scan (WBIS) is necessary for localization of any abnormal radioiodine avid lesions. However false-positive radioiodine uptake in WBIS can be problematic. We report a 32 years old female patient with PTC. After thyroidectomy and radioiodine therapy WBIS was performed. In her post therapy WBIS, there were zo...
