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 111In-diethylenetriaminepentaacetic acidoctreotide, scintigraphy with 123I-metaiodobenzylguanidine (MIBG), and 18F-FDG PET. M...

OBJECTIVE To determine the sensitivity and specificity of thallium scintigraphy in detection of coronary artery disease in diabetic patients. STUDY DESIGN Cross-sectional validation study. PLACE AND DURATION OF STUDY The study was carried out from July to December 2007 in the Cardiology Department of the Pakistan Institute of Medical Sciences, Islamabad. METHODOLOGY A total of 60 diabetic...

Somatostatin receptor (SS-R) scintigraphy has been successfully used in the visualization of a variety of neuroendocrine tumours. In vitro studies have shown that SS-Rs are present in human malignant lymphomas. We conducted a prospective study in 56 consecutive untreated patients with histologically proven Hodgkin's disease (HD) and compared the results of SS-R scintigraphy with physical and ra...

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...
