PURPOSE The aim of this study was to compare the diagnostic efficacy of whole-body magnetic resonance imaging (WB-MRI) as a new and rapid examination technique with skeletal scintigraphy for detection of skeletal metastases from solid tumors. MATERIAL AND METHODS In 129 patients with solid malignant tumors, WB-MRI was performed for individual comparison with skeletal scintigraphy. Examination...

OBJECTIVES We aimed to investigate the reliability of thyroid ultrasonography (US) and scintigraphy in determining the type of thyroid dysgenesis (TD). METHODS The study included 82 children (8.0±5.6 years) with a diagnosis of TD by thyroid scintigraphy with (99m)Tc and/or US. The patients were re-evaluated 6.0±5.1 years after the diagnosis. Thyroid US was performed in all cases, regardless o...

Objective. To compare the use of radiolabelled human monoclonal anti-TNF-a scintigraphy with clinical examination and MRI of hands and wrists joints in patients with active RA. Methods. Eight patients with active RA, 28-joint DAS (DAS-28)53.2 and a healthy volunteer underwent whole body and hand/wrist scintigraphy after the administration of anti-human TNF-a labelled with technetium-99m (Tc). O...

Objective. To determine the prevalence of missed lesions for parathyroid 4-dimensional computed tomography (4D CT) and scintigraphy and to describe the factors leading to missed lesions for both modalities. Study Design. Case series with chart review. Setting. Single center, hospital based. Subjects and Methods. Forty patients undergoing 4D CT and scintigraphy before parathyroidectomy between J...

BACKGROUND The imaging techniques most commonly used in the diagnosis of hyperparathyroidisms are ultrasound and scintigraphy. The diagnostic algorithms vary, depending mainly on the population, and experience of physicians. AIM Aim of the present research was to determine the usefulness of parathyroid scintigraphy and ultrasonography in patients diagnosed for hyperparathyroidism in own mater...

UNLABELLED Functional techniques are playing a pivotal role in the imaging of cancer today. Our aim was to compare, on a head-to-head basis, 3 functional imaging techniques in patients with histologically verified neuroendocrine tumors: somatostatin receptor scintigraphy (SRS) with (111)In-diethylenetriaminepentaacetic acid-octreotide, scintigraphy with (123)I-metaiodobenzylguanidine (MIBG), an...

BACKGROUND Active spondylolysis is an acquired lesion in the pars interarticularis and is a common cause of low back pain in the young athlete. OBJECTIVES To evaluate whether the one-legged hyperextension test can assist in the clinical detection of active spondylolysis and to determine whether magnetic resonance imaging (MRI) is equivalent to the clinical gold standard of bone scintigraphy a...

OBJECTIVES To review the findings of the patients with Sjögren's syndrome (SS) having technetium99-m-pertechnetate (99mTc-pertechnetate) and gallium67- citrate (Ga-67) salivary gland scintigraphy in the past eight years. METHODS The patients with SS, who were referred to our department for salivary gland scintigraphy during January -2008December 2015 were studied using both 99mTc-pertechnetat...

BACKGROUND Lymphoid cells may express somatostatin receptors (SS-Rs) on their cell surface. Therefore radiolabeled somatostatin analogues may be used to visualize SS-R-positive lymphoid neoplasms in vivo. Exact staging is the basis for treatment decisions in cutaneous malignant lymphoma. We considered the possibility that SS-R scintigraphy might offer a clinically useful method of diagnostic im...

This study aimed to evaluate the performance of a therapeutic vibrating mesh-type nebulizer for pulmonary delivery radioaerosols lung scintigraphy in healthy subjects. Six subjects (mean age 28.7 ± 6.2 years) inhaled 2 mL Tc-99m diethylenetriaminepentaacetic acid and normal saline solution (20 mCi) via (DK010, DELBio, Taipei, Taiwan). The nebulizer’s mass median aerodynamic diameter was between...
