Ultrasound scanning and 99mTc sulphur colloid scintigraphy are widely used in the diagnosis of the Budd-Chiari syndrome and have been compared at the time of presentation in 18 patients in whom the diagnosis was subsequently confirmed by histology and hepatic venography. Ultrasound was diagnostic in 16 (87%). The findings seen most often included hepatic vein abnormalities, caudate lobe hypertr...

Although not as well standardized as gastric emptying (GE) scintigraphy, esophageal transit scintigraphy, if performed in a comprehensive manner including both quantitative and qualitative analysis of single- and multiple-swallow studies, is clinically useful when expertise in esophageal manometry is not available or not tolerated and when esophageal manometry or barium videofluoroscopy results...

Purpose: To identify and interrogate the role of Gallium-67 scintigraphy in the diagnosis of Sarcoidosis. Methods: A retrospective study of 75 patients with suspected Sarcoidosis in a large teaching hospital with a specialist Sarcoidosis Centre. Results: Ga-67 scintigraphy in patients considered on clinical grounds to have Sarcoidosis is a useful and sensitive test, and furthermore, by relaxing...

UNLABELLED 111In-granulocyte scintigraphy is often used as a diagnostic tool in patients with fever of unknown origin (FUO). However, its diagnostic performance has been studied in only a limited number of investigations, with most having been published more than 10 y ago; in addition, a broad range of sensitivities and specificities has been reported. Therefore, the aim of this study was to in...

testicular scintigraphy has been well validated in the evaluation of patients with suspected testicular torsion and provides an accurate evaluation of testicular perfusion at the lime of imaging. however, the presence of normal or increased perfusion to the testis does not definitively exclude the necessity for surgical intervention. a case of intermittent testicular torsion, with a review of t...

background: local ablative treatments play an important role for patients who cannot be treated surgically. radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. microwave ablation (mwa) is a new minimally invasive treatment promising several improvements. the aim of this retrospective study was to evaluate the eff...

OBJECTIVE The optimization of medical exposure is one of the major issues regarding radiation protection in the world, and The International Committee of Radiological Protection and the International Atomic Energy Agency recommend establishing diagnostic reference levels (DRLs) as tools for dose optimization. Therefore, the development of DRLs based on the latest survey has been required for nu...

UNLABELLED The emergence of MRI has challenged the long-standing primacy of skeletal scintigraphy in pediatric cases of suspected acute hematogenous osteomyelitis (AHO) with nondiagnostic radiographs. This study evaluated a strategy in which skeletal scintigraphy is the primary and MRI a supplemental test. METHODS We reviewed the records of 213 children (age range, 8 mo-18 y; mean age, 67 mo)...

Pulmonary embolism (PE) is a preventable cause of morbidity and mortality which needs prompt recognition. Ventilation-perfusion (V/Q) scan is a well-established diagnostic test for evaluation of suspected PE. We report a 32-year-old woman with history of rheumatologic disease and acute dyspnea, who was referred for V/Q scintigraphy. The planar images revealed multiple mismatched defects through...
