OBJECTIVES The objective of this study was to evaluate the performance and utility of (99m)Tc HYNIC-TOC planar scintigraphy and SPECT/CT in the diagnosis, staging and management of gastroenteropancreatic neuroendocrine tumors (GPNETs). METHODS 22 patients (median age, 46 years) with histologically proven gastro- entero- pancreatic NETs underwent (99m)Tc HYNIC-TOC whole body scintigraphy and r...
UNLABELLED Delayed perfusion and enhanced hepatobiliary uptake are recognized findings on (99m)Tc-mercaptoacetyltriglycine ((99m)Tc-MAG3) scintigraphy in patients with renal insufficiency. Less well appreciated is the finding of bone marrow visualization. This study was performed to determine the frequency of this sign and to try to determine its association with laboratory parameters. METHOD...
UNLABELLED Planar lung scintigraphy is a standard method used for the diagnosis of lung embolism, but it is hampered by the high incidence of nondiagnostic tests. Ventilation/perfusion SPECT may possibly improve this situation. The objective of this study was to compare planar lung scintigraphy with ventilation/perfusion SPECT using pigs with artificially engendered lung emboli labeled with (20...
hepatobiliary scintigraphy is a sensitive method for intra & extera hepatic bile leak diagnosis. bile lead may be seen after hepatobiliary surgery, trauma, inflammatory disease or malignant neoplasms. although sonography and ct scanning are useful for diagnosis of peritoneal or perihepatic fluid, they cannot prove bile ascites. hepatobiliary scintigraphy with tc-99m-ida agents is a physiolo...
Aims In transthyretin amyloid (ATTR) amyloidosis various principal phenotypes have been described: cardiac, neuropathic, or a mixed cardiac and neuropathic. In addition, two different types of amyloid fibrils have been identified (type A and type B). Type B fibrils have thus far only been found in predominantly early-onset V30M and in patients carrying the Y114C mutation, whereas type A is note...
Objective. To create a ureteral obstruction experimental model that can be proved through (99m)Tc-DTPA renal scintigraphy and histopathological studies, without causing total renal function loss. Materials and Methods. Ten New Zealand white rabbits were submitted to a surgical experiment to create a model of unilateral obstruction to urinary flow. Surgery procedure provided unilateral ureteral ...
Abstract Parathyroid scintigraphy is an imaging technique that uses gamma-emitting radionuclide to locate hyperfunctioning parathyroid glands in patients with hyperparathyroidism. It valuable for preoperative assessment before parathyroidectomy, which a curative surgery most cases of primary hyperparathyroidism and some secondary There are several different techniques scintigraphy. In general, ...
BACKGROUND Management of cardiac amyloidosis (CA) is related to amyloid deposition. Our aim was to assess the effect of amyloid deposition on myocardial function. METHODSANDRESULTS Twenty-eight patients with transthyretin mutation and a group of 14 controls underwent echocardiography to quantify left ventricular (LV) dimensions, function, and global (G) longitudinal (L), radial (R) and circum...
Neuroblastoma is the most common extracranial solid malignancy in children, but is rare in adults. We report the case of a 33 year old man with recurrence of neuroblastoma, 2 years after the excision of the primary tumor in the right adrenal gland. The iodine-123-radioiodinated metaiodobenzylguanidine ((123)I-MIBG) and (99m)Tc-methylene diphosphonate ((99m)Tc-MDP) bone scans and the fluorine-18...
AIM Various studies have been conducted for determining the most optimal method for the early diagnosis of local recurrent or distant metastatic thyroid cancers. The aim of this study was to evaluate the clinical utility of technetium-99m (Tc-99m)-labeled octreotide derivatives in the detection of recurrence or distant metastases in medullary thyroid cancer patients and to compare the lesions w...
