we reported a 14 months old boy referred for evaluation of chylous ascites to our nuclear medicine department. tc-99m phytate was injected subcutaneously in his calves and whole body images as well as abdominal spect were performed. the spect images could localize an area of several intestinal lymphangiomata in the abdominal region. the abnormal region was surgically resected and the patient as...

PURPOSE To investigate the influence of partial colectomy associated with hepatectomy on the biodistribution of the (99m)Tc-phytate, on metabolic parameters, as well as labeling and morphology of red blood cells. METHODS Wistar rats were distributed into three groups (each with six), nominated as colectomy, colectomy+hepatectomy and sham. In the 30(th) postoperative day all rats were injected...

sentinel lymph node is the first regional lymph node that drains the lymph from the primary tumor. it is potentially the first nodeto receive the seeding of lymph‑borne metastatic cells. this study aimed to discuss lymphoscintigraphy procedural guidelines fordetection of sentinel node using tc‑phytate in isfahan, iran. moreover, the preliminary results of the first year’s clinical experience of...

We reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. She was planned to undergo mastectomy and lymphatic mapping. A dose of Tc-99m Phytate was injection in the peri-areolar region in an intra-dermal fashion. Two hours post-injection no sentinel node was visible in the axilla. Due to a high liver uptake, inadvertent intra-...

UNLABELLED Many groups have reported the adsorption or retention of (99m)Tc-radiopharmaceuticals on injection vials and disposable plastic syringes. Such an enormously high loss of radioactivity would result in poor images, radiation exposure, waste, and economic burdens. We therefore decided to investigate the extent of adsorption or retention of several (99m)Tc-radiopharmaceuticals on injecti...

amyloidosis is characterized by an abnormal extracellular deposition of amyloid in different organs, where it usually causes some type of dysfunction. its cause is unknown. five different types of amyloidosis have been described according to the underlying disease; immunoglobulin amyloidosis, familial amyloidosis, senile systemic amyloidosis, secondary amyloidosis and hemodialysis-associated am...
