urinary tract infections are common in children. the available gold standard method for diagnosis, tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation. this study was performed to compare and assess the efficacy of power doppler ultrasound versus tc-99m dmsa scan for diagnosis of acute pyelonephritis. a quasi experimental study was conducted...

abstract background: screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (apn). diuretic tc-99m mercaptoacetyltriglycine (mag3) scintigraphy with zero time injection of furosemide (mag3-f0) was observed to display focal parenchymal disorders. the advantages of mag3 include: lower radiation dose and short duration of the test. the aim of this stu...

BACKGROUND AND THE PURPOSE OF THE STUDY Technetium-99m is the major radionuclide used in the world and mainly is provided by fission product. However extensive research has been conducted on the use of accelerators for production of (99m)Tc. This investigation reports the production of (99m)Tc radioisotope using cyclotrons and the preparation, quality control and biodistribution studies of four...

introduction due to limitation of colonoscopy in assessing the entire bowel and patients’ intolerance in inflammatory bowel disease (ibd), in the current study, we aimed to prospectively compare the accuracy of 99m tc(v)-dimercaptosuccinic acid (dmsa) and fecal calprotectin with ileocolonoscopy as new methods for localizing inflammations. methods current prospective study conducted between 2012...

This case report illustrates the dynamic and static renal scintigraphic images of a patient with an unusual large diverticulum of the renal pelvis. The initial diagnosis by intravenous pyelography (IVP) and ultrasonographic (US) examination was a renal pelvic diverticulum of the left kidney, and the patient was referred to the nuclear medicine department for exploration of the effect of the pel...

We reviewed Tc-99m DMSA scintigraphy in children with vesicoureteral reflux (VUR) in order to assess whether repeated Tc-99m DMSA scans are necessary for the follow up of these patients. Ninety-seven children who were followed up for more than one year (1-7.4 years, average 2.8 years) after the first DMSA scan were included in the study. Fifty-one patients had been diagnosed as primary VUR and ...

A 2.5-year-old boy with a history of the previous incidental finding of an ectopic kidney in ultrasonography was referred to our nuclear medicine center for 99mTc-DMSA renal scintigraphy. The scan showed an unusual type of ectopic fused kidneys on the right side of the lower abdomen. In this anomaly, kidneys were fused completely across the medial portion of both upper and lower pole...

Urinary tract infection (UTI) is a common disease in childhood specially in female. In this study 50 patients with stablished diagnosis of UTI were evaluated by both renal scan with Tc-99m DMSA and renal sonography. The study revealed that most urinary tract infections are in children, Female sex between 5-9 years of age. Therefore the most important complications (Renal scarring) are als...
