A 58-year-old diabetic male with hepatic cirrhosis presented with fever and vague bone pains. Technetium methylene diphosphonate (Tc MDP) three phase bone scan (Figures 1 and 2) identified not only multiple sites of bone involvement but also extraskeletal renal involvement that was later proven by culture. Burkholderia pseudomallei was isolated from a blood culture, confirming a diagnosis of sy...

OBJECTIVE The aim of this study was to compare the renal function measured with either 99mTc-DTPA or 99mTc-EC dynamic scintigraphies with that measured using 99mTc-DMSA static scintigraphy. METHODS the values of relative renal function measured in 111 renal dynamic scintigraphies performed either with 99mTc-DTPA (55 studies) or with 99mTc-EC (56 studies) were compared with the relative functi...

Neuroblastoma is the third most common malignancy of childhood. Nowadays, MIBG has become a central procedure for staging and defining extent and location of neuroblastoma tumors. The recommendations of the International Neuroblastoma Staging System (INSS) indicate that MIBG scintigraphy must be performed in patients with neuroblastoma at the time of initial staging and as a followup tool durin...

The skeleton is a metabolically active organ that undergoes continuous remodelling throughout life. Normal healthy bones are dynamic structures with inherent basal levels of turnover sustained by balanced osteoblastic and osteoclastic activity. Increased bone turnover (ie osteoblastic activity) is the central mechanism of attempts at bone healing in case of any insult, whether it is benign or m...

INTRODUCTION L,L-ethylenedicysteine (EC) is a new carrier of technetium Tc 99m (99mTc) with a lower affinity to plasma albumin in comparison with diethylenetriamine pentaacetic acid (DTPA). We compared 99mTc-EC scan with 99mTc-DTPA scan in diuretic renography for patients with obstructive uropathy. MATERIALS AND METHODS Thirty-three patients with upper urinary tract obstruction were randomly ...
