BACKGROUND/AIM Ureteropelvic junction obstruction and vesicoureteral reflux are the most frequent entities identified on the basis of antenatal hydronephrosis. The aim of this study was to determine the incidence and pattern of abnormal renal scintigraphy findings in postnatal investigation of children with antenatal hydronephrosis. METHODS Twenty-four infants (19 boys and five girls) present...

Introduction: It has been suggested that calculation of differential renal function (DRF) using 99mTc-DMSA may lead to overestimation of the function of an obstructed kidney. The aim of this study was to evaluate the effect of diuretic administration on the determination of DRF using 99mTc-DMSA scintigraphy in patients with dilated pelvis. Methods: Thirty three patients, aged from 2 month...

Primary hyperparathyroidism caused by parathyroid adenoma requires surgical resection. To confine the extent of surgery to very minimum and exclude an atypical location, preoperative imaging aims at identifying suspicious gland. For this purpose, Technetium-99m (99mTc)-sestamibi scintigraphy SPECT have become international standard, in inconclusive cases also with C-11 methionine F-18 choline P...

The ideal imaging method in inflammatory bowel disease would reliably detect inflammation, identify the correct intestinal location, and assess the severity of the disease. The aim of this study was to compare scintigraphic methods of quantifying overall disease activity using both indium-111 (111In) and technetium-99M (99mTc) HMPAO labelled leucocyte scans. The four day faecal excretion of 111...

BACKGROUND Assessing the neuroendocrine (NE) pattern in castration-resistant prostate cancer (CRPC) may prove useful in selecting potential responders to target therapies such as somatostatin analogues. The aim of this study was to define a panel of markers or examinations appropriate to characterize NE differentiation (NED). METHODS Forty-seven patients with CRPC underwent a systematic diagn...

OBJECTIVE To investigate the in vivo and in vitro expression of somatostatin receptors (SS-R) on synovial membranes of patients with rheumatoid arthritis (RA). METHODS The joints of 14 consecutive patients with active RA, 4 patients with severe osteoarthritis (OA), and 30 control patients were studied. The somatostatin analog [111In-DTPA-D-Phe1]-octreotide was used for in vivo SS-R scintigrap...
