OBJECTIVES To analyze the predictive values of selective venous sampling (SVS) in our own experience and in a systematic meta-analysis of the international literature and to compare them with the results of noninvasive localization studies before reoperative parathyroid surgery. DATA SOURCES Twenty-one consecutive patients with persistent or recurrent renal hyperparathyroidism underwent preop...

background: diagnosis of coronary artery disease (cad) in patients with left bundle branch block (lbbb) is considered as a challenge in cardiology due to the low accuracy of noninvasive methods such as basal and stress electrocardiography (ecg). this diagnostic challenge can be reduced but not eliminated using dipyridamole as a stress method instead of exercise. the aim of this study was to ass...

background renal scintigraphy with technetium 99m labeled dimercaptosuccinic acid (99mtc-dmsa) is a traditional imaging technique commonly used to detect renal scar in patients with probable vesicoureteral reflux (vur) and/or urinary tract infection (utis). we determined whether normal results of dmsa renal scan obviate the need for voiding cystourethrography (vcug) in evaluating children with ...

Sentinel node biopsy (SNB) in breast cancer is a promising surgical technique that avoids unnecessary axillary lymph node dissection. To optimize lymphatic mapping with radiopharmaceuticals, mammary lymphoscintigraphy with 30-50 MBq of technetium-99m-diethylenetriamine pentaacetic acid human serum albumin (99mTc-HSAD), technetium-99m-human serum albumin (99mTc-HSA), or technetium-99m-tin colloi...

Abstract Molybdenum-99 ( 99 Mo) is a parent radioisotope of Technetium-99m 99m Tc) widely used in nuclear diagnostics. The production this by PT. INUKI generated radioactive fission waste (RFW) that theoretically contains 239 Pu and 235 U, posing proliferation risk. This paper discusses the determination radionuclides inventory RFW proposed strategy for its management. was calculated using ORIG...

uclear imaging of the heart is fast emerging as a valuable and widely used non-invasive procedure, that reveals vital information about cardiac structure, physiology, perfusion and metabolism. Commonly perfonned nuclear imaging techniques in cardiology are radionuclide ventriculography (RNV) done by labelling autologous red blood cells with Technetium-99m (Tc-. 99m) and myocardial perfusion ima...

PURPOSE To evaluate whether scintigraphy with technetium-99m-labeled ceftizoxime ((99m)Tc-CFT) can differentiate mediastinitis from aseptic inflammation associated with sternotomy. METHODS Twenty female Wistar rats were randomly distributed into four groups: S (control) -partial upper median sternotomy with no treatment; SW (control) - sternotomy and treatment of sternal wounds with bone wax;...

A 10-year-old boy with a history of bloody discoloration of urine following recent appendectomy was referred to our department for urinary leakage/fistula evaluation. A renal Technetium-99m-L,L-ethylenedicysteine (99mTc-EC) scintigraphy was performed. After injection of radiotracer, a focus of activity appeared in the supralateral part of the right kidney which was confirmed as accum...

IMPORTANCE Parathyroid hormone (PTH)-secreting thymomas are an exceedingly rare entity. A PTH-secreting thymoma was discovered in the workup of a patient with primary hyperparathyroidism. A concomitant parathyroid adenoma was removed from the same patient. We present the intriguing clinical course and review the literature on this rare entity. In addition, we discuss the use of scanning with te...

Radionuclide myocardial perfusion imaging in conjunction with exercise or pharmacologic stress testing is an established technique for diagnosing and assessing the severity of coronary artery disease (1 ). Currently TI is the most widely used radiopharmaceutical for myocardial perfusion imaging. Thallium-201, however, has disadvantages such as low photopeak energy (69-83 keV), which can cause d...
