We describe two cases of right hyperglycemia hemichorea (HGHC) with identical Tc-99m TRODAT-1/ Tc-99m ECD scan findings. While the brain MRI showed signal alterations within the left putamen, there was evidence of hyperperfusion on Tc-99m TRODAT-1 but hypoperfusion on Tc-99m ECD within the left putamen, in association with hyperperfusion within left thalamus on Tc-99m ECD. The discrepancy betwe...

OBJECTIVE Two sequential (99m)Tc methylene diphosphonate (MDP) scans were performed on a 42-y-old woman with insulin-dependent diabetes mellitus, chronic right pyelonephritis and anemia. The initial scan showed reduced skeletal uptake with intense and diffuse hepatic uptake. Because these findings were similar to those seen when excessive hydrolyzed-reduced (99m)Tc colloids are present in the r...

Radionuclide Tc99m DTPA (Diethylenetriaminepenta Acetic Acid) renal imaging is being used to assist in the evaluation of overall GFR, the intra-renal transit time, the cortical transit time, response to frusimide injection, diagnosis of ATN and rejection in renal transplant cases. A study was conducted at PINSTECH in order to prepare DTPA kit locally and evaluate the labeling efficiency as well...

UNLABELLED After the extravasation of a therapeutic dose of (131)I-metaiodobenzylguanidine that produced a radiation burn to a patient's forearm, we instituted a catheter placement verification protocol. METHODS Before therapy infusion, proper placement is verified by administering 37 MBq of (99m)Tc-pertechnetate through the catheter, and monitoring activity at the administration site and on ...

A 21-year-old patient with long-standing inferior vena cava obstruction secondary to idiopathic thrombosis extending from the external iliac veins underwent a radionuclide venography with Tc-99m pertechnetate labeled erythrocytes. The blood pool phase of the study revealed bilaterally distorted inferior epigastric veins mimicking normal venous flow pattern. The authors present this case to disc...

OBJECTIVE To perform a retrospective review of all patients receiving technetium-99m ((99m)Tc)-labelled sulesomab over a 4-year period to determine if soft tissue infections can be accurately identified. METHODS AND MATERIALS We reviewed the results of 124 (99m)Tc-sulesomab studies performed over a 4-year period. Of these, 34 were performed for undiagnosed fever in which soft tissue infection...

UNLABELLED All patients with primary hyperparathyroidism should undergo localization studies before reoperation, but it is not known which method is most accurate. The purpose of this prospective study was to compare the performance of planar scintigraphy with (123)I/(99m)Tc-sestamibi, (99m)Tc-sestamibi SPECT (SPECT/CT), (11)C-methionine PET/CT, and selective venous sampling (SVS) in persistent...

introduction: in the current study, we evaluated the feasibility of body outlining using tc-99m filled flood source for lymphoscintigraphy imaging. methods: 80 patients were included in the study. sentinel node mapping was done using tc-99m antimony sulfide colloid. for outlining the body a tc-99m filled flood source was used which was placed behind or lateral to the patients for anterior and ...

We report a case of Sipple's syndrome with a hepatic tumor. A 28-year-old male with medullary thyroid cancer and bilateral pheochromocytomas was diagnosed as having Sipple's syndrome. The hepatic tumor was found to be hypervascular by means of a dynamic abdominal CT scan. An I-131-MIBG scan showed no increased accumulation in the tumor. A whole body Tc-99m-MIBI scan had shown, however, increase...

using gate’s technique for gfr measurement with gamma camera, the patient is received 5mci of tc-99m-dtpa. by this amount of radioactivity, good quality renal scan is not possible. this study tries to optimize gate’s technique for gfr measurement during routine renal scan (with 10-15 mci). methods and materials: scanning was performed for 60 seconds from samples of tc-99m with activities of 3, ...
