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 ...

We investigated the diagnostic capabilities of I-131, Tl-201, and Tc-99m-MIBI (hexakis-2-methoxyisobutyl-isonitrile) scintigraphy for thyroid cancer metastases after total thyroidectomy over the entire body and for every locus before and after thyroid bed ablation. After total thyroidectomy of thyroid cancer, 36 cases were subjected to I-131 treatment 64 times. They consisted of 17 men and 19 w...

Accumulation of both Tc-99m pertechnetate and radioiodine upon scintigraphy in thyroid carcinoma and/or in its metastases is a rare occurrence. In this paper we describe a patient who was taken to surgery for left lobectomy of the thyroid with follicular adenocarcinoma and who had accumulation of both I-131 and Tc-99m pertechnetate in lung metastases. The accumulation of I-131 was less than tha...

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...

thyroid scintigraphy has been helpful in detecting and evaluation of thyroid nodules. sodium pertechnetate tc-99m is the most commonly used radionuclide for thyroid imaging because of its general availability, favorable dosimetric characteristics and low cost. but, there are reports of occasional disparity in isotope uptake in lesions compared with radioiodide. in order to determine percentage ...

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...
